17.1: Population Dynamics
17.1.1: Fertility
There are a number of different ways, taking different factors into account, to measure fertility rate.
Learning Objective
Examine the impact of fertility rates on society and the various ways fertility is computed and discussed
Key Points
- There are a number of different approaches to measuring fertility rate—such as crude birth rate (CBR), general fertility rate (GFR), child-woman ratio (CWR), total fertility rate (TFR), gross reproduction rate (GRR), and net reproduction rate (NRR).
- Fertility rates are influenced by a number of factors, including intentional measures such as contraception and major social events.
- Demographers have posited a demographic-economic paradox, in which fertility rates decline as countries become more economically developed.
- Almost universally, higher levels of educational attainment correspond to lower fertility rates.
Key Terms
- fecundity
-
Ability to produce offspring.
- contraception
-
The use of a device or procedure to prevent conception as a result of sexual activity.
- fertility
-
The birthrate of a population; the number of live births per 1000 people per year.
Example
- Replacement level refers to the fertility rate needed to maintain a stable population size. Imagine that you have a fish tank with four fish, and that every year, one fish dies. In order to meet the replacement level, one new fish would have to be born every year to maintain a population of four fish over time. If three of the original fish were female and capable of laying an egg, they would have to exhibit a fertility rate of .33 to reach replacement level.
In demography, fertility refers to the actual production of offspring, rather than the physical capability to produce, which is called fecundity. To estimate how quickly a population is growing, demographers must know how frequently people are added to the population by being born, so they measure fertility. There are a number of different approaches to measuring fertility rate—such as crude birth rate (CBR), general fertility rate (GFR), child-woman ratio (CWR), total fertility rate (TFR), gross reproduction rate (GRR), and net reproduction rate (NRR).
Period Measures
Crude birth rate (CBR) is the number of live births in a given year per 1,000 people alive at the middle of that year. General fertility rate (GFR) is the number of births in a year divided by the number of women of childbearing age (usually 15 to 49 years old, or sometimes 15 to 44 years old), times 1000. It focuses on potential mothers only, and takes the age distribution into account. Child-Woman Ratio (CWR) is the ratio of the number of children under 5 to the number of women 15-49, times 1000.
Cohort Measures
Age-specific fertility rate (ASFR) is the number of births in a year to women in a 5-year age group, divided by the number of all women in that age group, times 1000. The usual age groups are 10-14, 15-19, 20-24, etc.
Total fertility rate (TFR) is the total number of children a woman would bear during her lifetime if she were to experience the prevailing age-specific fertility rates of women and survive until the end of her reproductive life . TFR equals the sum for all age groups of 5 times each ASFR rate. The TFR is a synthetic rate, not based on the fertility of any real group of women since this would involve waiting until they had completed childbearing. The TFR represents the average number of children a woman would have were she to fast-forward through all her childbearing years in a single year, under all the age-specific fertility rates for that year.
Total Fertility Rate
This map shows countries coded by total fertility rates, with 0-1 children at the bottom of the spectrum and 7-8 at the top. A number of factors, such as development index and religious tradition, contribute to variations in fertility rates.
The TFR (or TPFR—total period fertility rate) is a better index of fertility than the crude birth rate because it is independent of the age structure of the population, but it is a poorer estimate of actual completed family size than the total cohort fertility rate. In particular, the TFR does not necessarily predict how many children young women now will eventually have, as their fertility rates in years to come may change from those of older women now.
Gross reproduction rate (GRR) is the number of girl babies who would be born to a woman completing her reproductive life at current age-specific fertility rates. It assumes that all of the baby girls will grow up and live to at least age 50. Like the TFR, the GRR ignores life expectancy. It assumes that all women will survive at least until the end of their reproductive lives.
Net reproduction rate (NRR) starts with the GRR and adds the realistic assumption that some of the women will die before age 59; therefore they will not be alive to bear some of the potential babies that were counted in the GRR. NRR is always lower than GRR, but in countries where mortality is very low, almost all the baby girls grow up to be potential mothers, and the NRR is practically the same as GRR.
Factors Impacting Fertility
Human fertility depends on a long list of factors, including physical health and nutrition, sexual behavior, culture, instinct, endocrinology, timing, economics, way of life, and emotions. Fertility rates vary among countries and cultures because these factors vary. Demographers study the factors that affect fertility in order to better understand fertility patterns and their variance. Three of the major categories they study are physical health and nutrition, sexual behavior and human fertility, and political issues regarding childbirth and childrearing.
Population Control
The birth rate is an issue of concern for many governments and policymakers. Some, including those of Italy and Malaysia, seek to increase the national birth rate using pronatal measures such as financial incentives to new mothers. Conversely, other countries have policies to reduce the birth rate, such as China’s former one-child policy.
In some places, government policies have been focused on reducing birth rates by improving women’s sexual and reproductive health and rights. Typically, high birth rates have been associated with health impairments and low life expectancy, low living standards, low status of women, and low levels of education. There are claims that as countries go through economic development and social change, birth rate declines. Indeed, demographers consistently find that one of the strongest predictors of fertility rates is women’s educational attainment. Almost universally, higher levels of educational attainment correspond to lower fertility rates.
Fertility Rate and Human Development Index
Fertility has been found to correlate to human development index, with more developed countries having lower fertility rates than less developed ones.
17.1.2: Mortality
Mortality rate measures the number of deaths in a population over a given period of time.
Learning Objective
Explain the various ways mortality is calculated, such as the crude death rate, infant mortality rate and life expectancy
Key Points
- Like fertility, mortality rate can be measured in a number of ways.
- Specific measures of mortality include the crude death rate, the infant mortality rate, and life expectancy.
- Infant mortality rates measure the annual number of deaths of chldren less than 1 year old per thousand live births.
- Life expectancy measures the number of years that an individual at a given age can expect to live, given present mortality rates.
- Different causes of death become more or less prevalent as countries become more economically developed, and death rates vary between countries.
- Different causes of death become more or less prevalent as countries become more economically developed, and death rates vary between countries.
Key Terms
- crude death rate
-
the total number of deaths per year per 1000 people
- life table
-
In actuarial science and demography, a life table is a table which shows, for each age, what the probability is that a person of that age will die before his or her next birthday (“probability of death”).
- Causes of death
-
The causes of death tend to vary between countries. For example, mortality due to malnutrition tends to be much higher in developing countries, whereas in developed countries, people are more likely to die of age-related diseases.
Examples
- If you have a tank of one thousand goldfish and 100 die in the first year, they exhibit a mortality rate, or crude death rate, of 100 deaths/1000 members of the population, or 10%.
- Men and women may have different life expectancies, so mortality rates can vary with the gender distribution of a population. Thus, for example, the number of deaths per 1000 people can be higher for developed nations than in less-developed countries, despite life expectancy being higher in developed countries due to standards of health being better.
Mortality rate is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. This measure is also called the crude death rate. As of July 2009 the crude death rate for the whole world is about 8.37 per 1000 per year according to the current CIA World Factbook.
Just as demographers measure fertility in different ways, they also measure mortality in various ways. Some of the more common demographic measures of mortality include the crude death rate (the annual number of deaths per 1000 people), the infant mortality rate, or the annual number of deaths of children less than 1 year old per thousand live births, and life expectancy, which measures the number of years that an individual at a given age can expect to live, given present mortality rates.
Like fertility, mortality also depends on the age and gender distribution of a population. Older people are more likely to die, so countries with a higher proportion of old people may also have a higher mortality rate. Similarly, men and women may have different life expectancies; therefore, mortality rates can vary with the gender distribution of a population. Thus, for example, the number of deaths per 1000 people can be higher for developed nations than in less-developed countries, despite life expectancy being higher in developed countries due to better standards of health. This happens because developed countries typically have a completely different population age distribution, with a much higher proportion of older people, due to both lower recent birth rates and lower mortality rates.
To more accurately estimate mortality rates, demographers calculate age and gender specific mortality rates. These rates are compiled in a life table, which shows the mortality rate separate for each age group and gender. A life table is necessary to give a good estimate of life expectancy.
Like fertility, mortality rates vary between countries, especially between developing and developed countries. Overall, developing countries tend to have higher mortality rates, higher infant mortality rates, and lower life expectancies. The causes of death also tend to vary between countries. For example, mortality due to malnutrition tends to be much higher in developing countries, whereas in developed countries, people are more likely to die of age-related diseases.
Sociologists have theorized that one of the best predictors of longevity, or a high life expectancy, is education, even when other factors are controlled, people with more education tend to live longer. A few additional years of schooling statistically corresponds to several additional years of life expectancy and vastly improved health in old age. The mechanism through which this works is not the schooling itself, but rather schooling’s influence on other health-related behaviors. Education tends to lower the likelihood of smoking and engaging in unhealthy and high risk behaviors. Education also increases the probability of engaging in healthy behaviors, like exercise.
Crude Death Rate by Country
The crude death rate is a measure of how many people per 1000 members of a population die each year. It varies between countries based on various economic, social, and environmental factors.
17.1.3: Migration
Migration is the movement by people from one place to another.
Learning Objective
Discuss the types of migration in society and the various theories that explain migration
Key Points
- Migration is the physical movement by people from one place to another; it may be over long distances, such as from one country to another, and can occur as individuals, family units, or large groups.
- Lee’s laws divide factors causing migrations into two groups of factors: push and pull factors. Push factors are things that are unfavorable about the area that an immigrant is coming from; pull factors are things that attract the immigrant to the new location.
- Types of migration include seasonal migration, urbanization, suburbanization, and forced migration.
- International migration is known as immigration.
- Sociologists use multiple theories to explain migration based on economic and social factors.
Key Terms
- immigration
-
The passing or coming of a person into a country for the purpose of permanent residence.
- emigration
-
The movement of a person or persons out of a country or national region, for the purpose of permanent relocation of residence.
- Seasonal migration
-
Movement from one place to another generally associated with agriculture and tourism; seasonal agricultural migrants follow crop cycles, moving from place to place to plant or harvest crops.
Example
- An example of internal migration that is motivated by both social and economic factors is the trend among young, well-educated Americans to move to large cities after college or graduate school. This migration pattern, which abandoned cities refer to as “the brain drain,” occurs as young graduates seek high-paying jobs and powerful social networks.
Human Migration
Migration is the physical movement by people from one place to another; it may be over long distances, such as from one country to another, and can occur as individuals, family units, or large groups. When referring to international movement, migration is generally called immigration.
Lee’s laws divide factors causing migrations into two groups of factors: push and pull factors. Push factors are things that are unfavorable about the area that an immigrant is coming from; pull factors are things that attract the immigrant to the new location.Historically, migration has been nomadic, meaning people sustained movement from place to place over their lifetimes. Although only a few nomadic people have retained this lifestyle in modern times, migration continues as both involuntary migration (such as the slave trade, human trafficking, and ethnic cleansing) and voluntary migration within a region, country, or beyond. Specific types of migrants can include colonizers (who forcefully enter into a country or territory), refugees (who are forced to flee their country), and temporary migrants (who travel to a new place temporarily, such as business travelers, tourists, or seasonal farm workers).
Along with fertility and mortality, migration is one of three major variables studied by demographers to measure population change.
Types of Migration
Seasonal migration is generally associated with agriculture and tourism. Seasonal agricultural migrants follow crop cycles, moving from place to place to plant or harvest crops. Some countries, including the United States, allow special permits for seasonal agricultural workers to temporarily work in the country without granting full citizenship rights. Seasonal tourists seek out certain natural amenities, like snow-capped mountains for skiing and winter sports or desert sunshine for a break from oppressive winters.
Urbanization refers to migration from rural to urban areas. Since the 1970s, urbanization has become more common in developing countries, where industrialization has made agriculture more efficient and has increased the demand for urban labor. Previously, massive urbanization also took place in developed countries; beginning in Britain in the late eighteenth century, millions of agricultural workers left the countryside and moved to the cities.
Industrialization also sparked transnational labor migration that has further swelled urban populations. In the early twentieth century, transnational labor migration reached a peak of three million migrants per year. During this period, emigration rates were especially high in Italy, Norway, Ireland and the Guangdong region of China.
In the United States, industrialization also led to considerable internal migration (or human migration within a nation) of African Americans from the rural South to the urban North. From 1910-1970, approximately seven million African Americans migrated north to escape both poor economic opportunities and considerable political and social prejudice in the South. They settled in the industrial cities of the Northeast, Midwest, and West, where relatively well-paid jobs were available. This phenomenon came to be known in the United States as the Great Migration.
In many developed countries, urbanization has slowed and the population has begun to move out of cities — in some cases back to rural areas, but most frequently, to newly-built suburbs. The movement from cities to surrounding suburbs is called suburbanization and represents yet another form of internal migration.
Yet another kind of migration, forced migration refers to the coerced movement of a person or persons away from their home or home region. It has been a means of social control under authoritarian regimes, taking the form of ethnic cleansing, slave trades, human trafficking, and forced displacement.
Theories of Migration
According to neoclassical economic theory, labor migration is motivated primarily by wage differences between two geographic locations. These differences can usually be explained by differences in the supply of and demand for labor. Areas with a shortage of labor but an excess of capital will have a high relative wage, whereas areas with a high labor supply and a dearth of capital will have a low relative wage. Following neoclassical principles, migrants tend to move from low-wage areas to high-wage areas where their labor is in higher demand.
The new economics of labor migration theory criticizes neoclassical economic theory for its narrow focus on individual decisions. According to the new economics theory, migration flows and patterns cannot be explained solely at the level of individual workers and their economic incentives. Instead, wider social entities must be considered as well. One such social entity is the household. Migrants may choose to move in order to reduce the social and economic risk that a household experiences as a result of having insufficient income. The household, in this case, needs extra capital, which can be attained by family members who participate in migrant labor abroad and send money back home as remittances. These remittances can also have a broader effect on the economy of the receiving country as a whole as they bring in capital.
World systems theory looks at migration from a global perspective.It explains that interaction between different societies can be an important factor in social change within societies. Trade with one country, which causes economic decline in another, may create incentives to migrate to a country with a more vibrant economy. It can be argued that even after decolonization, the economic dependence of former colonies still remains.
Net Migration Rates by Country
Social, economic, and environmental conditions (such as unemployment, drought, or conflict) can drive large numbers of people to migrate across national borders, as shown by this map. Positive migration rates are indicated in blue; negative migration rates in orange; stable in green; and no data in gray.
17.2: Population Growth
17.2.1: Implications of Different Rates of Growth
Different rates of growth can lead to overpopulation or underpopulation, both of which have potential consequences.
Learning Objective
Discuss the implications both overpopulation and underpopulation can have for society
Key Points
- When the fertility rate is at the replacement level, a population will remain stable, neither growing nor shrinking.
- Fertility rates above the replacement level will cause the population to grow; fertility rates below the replacement level will cause the population to shrink.
- Overpopulation is judged relative to carrying capacity and can have deleterious effects. When the population is too large for the available resources, famine, energy shortages, war, and disease can result.
- Recently, in some countries, sub-replacement fertility rates have led to underpopulation. This can lead to economic decline, the aging of the population, and poverty.
Key Terms
- fertility rate
-
The average number of children that would be born to a woman over her lifetime if she followed the current average pattern of fertility among a given group of women and survived through her reproductive years; used as an indicator of strength of population growth.
- Replacement level
-
Regarding fertility, refers to the number of children that a woman must have in order to replace the existing population.
- gross domestic product
-
(GDP) The market value of all officially recognized final goods and services produced within a country in a year; often used as an indicator of a country’s material standard of living.
- carrying capacity
-
The number of individuals of a particular species that an environment can support.
Examples
- Urban areas in developing countries, such as Mumbai, India, have developed massive slums as population growth has exceeded the amount of available land and housing.
- In countries such as Italy, slow population decline has worried policymakers as GDP growth depends upon a large, skilled labor pool and a strong consumer market.
Fertility rates refer to the rates of birth per 1,000 women of reproductive age in a given population. When the fertility rate is at the replacement level, a population will remain stable, neither growing nor shrinking. However, when the fertility rate deviates from the replacement level, the size of the population will change. Fertility rates above the replacement level will cause the population to grow; fertility rates below the replacement level will cause the population to shrink.
The population reached 6 billion people around 1999, and increased to around 7 billion by 2012. However, in some countries the birth rate is falling while the death rate is not, leading to a decline in the population growth rate. The population growth rate has been decreasing in higher income countries; however the number of people added to the global population each year continues to increase due to increasing growth rates in lower income countries.
Overpopulation
High fertility rates lead to population growth, which, under certain circumstances, can cause a condition known as “overpopulation. ” Overpopulation is not a function of the number or density of individuals, but rather the number of individuals compared to the resources they need to survive. In other words, it is a ratio: population to resources. Humans are not unique in their capacity for overpopulation; in general terms, overpopulation indicates a scenario in which the population of a living species exceeds the carrying capacity of its ecological niche.
When estimating whether an area is overpopulated, resources to be taken into account include clean water, food, shelter, arable land, and various social services (such as jobs, money, education, fuel, electricity, medicine, proper sewage and garbage management, and transportation).
Overpopulation can have deleterious effects. When population outstrips available resources, calamity can result, including famine, shortages of energy sources and other natural resources, rapid and uncontrolled spread of communicable diseases in dense populations, and war over scarce resources, such as land. Dense populations may also settle available land and crowd out other land uses, such as agriculture.
Different rates of growth
Presently, every year the world’s human population grows by approximately 80 million. However, that population growth is not distributed evenly across all countries. Most population growth comes from developing countries, where birthrates remain high. Meanwhile, about half the world lives in nations with sub-replacement fertility. In some of these countries, the population has actually begun to shrink (e.g., Russia). All of the nations of East Asia – with the exceptions of Mongolia, the Philippines, and Laos – have fertility rates below replacement level. Russia and Eastern Europe are dramatically below replacement fertility. Western Europe also is below replacement. In the Middle East Iran, Tunisia, Algeria, Turkey, and Lebanon are below replacement. Some countries still have growing populations due to high rates of immigration, but have native fertility rates below replacement: Canada, Australia, and New Zealand are similar to Western Europe, while the United States is just barely below replacement with about 2.0 births per woman.
A new fear for many governments, particularly those in countries with very low fertility rates, is that a declining population will lead to underpopulation and will reduce the gross domestic product (GDP) and economic growth of the country, as population growth is often a driving force of economic expansion. To combat extremely low fertility rates, some of these governments have introduced pro-family policies that include incentives, such as payments to parents for having children and extensive parental leave for parents.
Slums in Mumbai
Rapid population growth in Indian cities has resulted in vast slums as populations have exceeded available land and housing.
17.2.2: Three Demographic Variables
The basics of demographic population growth depend on the rate of natural increase (births versus deaths) and net migration.
Learning Objective
Explain how population growth is calculated
Key Points
- Demography is the statistical study of human populations. It encompasses the study of the size, structure, and distribution of these populations, and spatial and/or temporal changes in them in response to birth, migration, aging, and death.
- Population change depends on the rate of natural increase and net migration.
- Natural increase is calculated by the fertility rate minus the mortality rate.
- Net migration depends on in-migration and out-migration.
Key Terms
- mortality rate
-
The number of deaths per given unit of population over a given period of time.
- demography
-
The study of human populations and how they change.
- Net migration
-
The difference of immigrants and emigrants of an area in a period of time, divided (usually) per 1,000 inhabitants (considered on midterm population). A positive value represents more people entering the country than leaving it, while a negative value mean more people leaving than entering it.
- Natural increase
-
Population growth that depends on the fertility rate and the mortality rate.
Example
- The United States illustrates how the rate of natural increase and net migration combine to create population change—the fertility rate in the U.S. is at almost exactly replacement level, but migration into the country is high enough to lead to population growth.
Demography is the statistical study of human populations. It can be a very general science that can be applied to any kind of dynamic living population, or one that changes over time or space. It encompasses the study of the size, structure, and distribution of these populations, and spatial and/or temporal changes in them in response to birth, migration, aging, and death.
Human population growth depends on the rate of natural increase, or the fertility rate minus the mortality rate, and net migration. The basics of demography can be reduced to this formula:
(Births – Deaths) +/- ((In-Migration) – (Out Migration)) = Population Change.
As this equation shows, population change depends on three variables: (1) the natural increase changes seen in birth rates, (2) the natural decrease changes seen in death rates, and (3) the changes seen in migration. Changes in population size can be predicted based on changes in fertility, mortality, and migration rates.
Natural increase refers to the increase in population not due to migration, and it can be calculated with the fertility rate and the mortality rate. Net migration is the mathematical difference between those migrating into a country and those migrating out of a country.
This basic equation can be applied to populations and subpopulations. For example, the population size of ethnic groups or nationalities within a given society or country is subject to the same sources of change as the national population. However, when dealing with ethnic groups, “net migration” might have to be subdivided into physical migration and ethnic re-identification (assimilation). Individuals who change their ethnic self-labels or whose ethnic classification in government statistics changes over time may be thought of as migrating or moving from one population subcategory to another. More generally, while the basic demographic equation holds true by definition, the recording and counting of events (births, deaths, immigration, emigration) and the enumeration of the total population size are subject to error. Allowance needs to be made for error in the underlying statistics when any accounting of population size or change is made.
US Fertility Rate
The US fertility rate has leveled off at about 2.0, which is nearly equal to the replacement level. This means that population growth in the US is due to inward migration, rather than a high birthrate.
17.2.3: Problems in Forecasting Population Growth
Population growth is difficult to predict because unforeseen events can alter birth rates, death rates, migration, or resource limitations.
Learning Objective
Explain the various ways sociologist try to estimate the rate of population growth, such as through fertility, birth and death rates
Key Points
- Population forecasts try to estimate the rate of population growth. However, unpredictable factors can change fertility rates, mortality rates, or migration rates, which can cause difficulty in forecasting.
- Certain government policies are making it easier and more socially acceptable to use contraception and abortion methods. Likewise, some countries are instituting pro-natalist policies to encourage fertility.
- Malthusian catastrophe refers to a scenario where overpopulation would compromise global food security, leading to mass starvation.
- In the future, food production be increased by innovations such as genetically modified crops, more efficiently employing agricultural technology, and aquaculture. This would raise the limit on the number of people the world can support.
Key Terms
- forecast
-
An estimation of a future condition.
- Birth rates
-
The birth rate is typically the rate of births in a population over time. The rate of births in a population is calculated in several ways: live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques.
- Green Revolution
-
Green Revolution refers to a series of research, development, and technology transfer initiatives, occurring between the 1940s and the late 1970s, that increased agriculture production around the world, beginning most markedly in the late 1960s
Examples
- The Green Revolution is an example of rapidly changing technology that lowered worldwide death rates, thus throwing off estimates of population change.
- Worldwide, nearly 40% of pregnancies are unintended (some 80 million unintended pregnancies each year). An estimated 350 million women in the poorest countries of the world either did not want their last child, do not want another child or want to space their pregnancies, but they lack access to information, affordable means and services to determine the size and spacing of their families.
Forecasts try to estimate the rate of population growth, but this is understandably difficult to predict. For example, the UN has issued multiple projections of future world population, based on different assumptions. From 2000 to 2005, the UN consistently revised these projections downward, until the 2006 revision, issued on March 14, 2007, revised the 2050 mid-range estimate upwards by 273 million. The UN now estimates that, by 2050, world population will reach 9 billion people. However, this forecast, like all population forecasts, is subject to change.
Population growth is difficult to predict because unforeseen events can alter birth rates, death rates, migration, or the resource limits on population growth. Birth rates may decline faster than predicted due to increased access to contraception, later ages of marriage, the growing desire of many women in such settings to seek careers outside of child rearing and domestic work, and the decreased economic “utility” of children in industrialized settings. Countries may also choose to undertake mitigation measures to reduce population growth. For example, in China, the government has put policies in place that regulate the number of children allowed to each couple. Other societies have already begun to implement social marketing strategies in order to educate the public on overpopulation effects. Certain government policies are making it easier and more socially acceptable to use contraception and abortion methods.
Such policies could have a significant effect on global fertility rates. Worldwide, nearly 40% of pregnancies are unintended (some 80 million unintended pregnancies each year). An estimated 350 million women in the poorest countries of the world either did not want their last child, do not want another child or want to space their pregnancies, but they lack access to information, affordable means and services to determine the size and spacing of their families. In the United States, in 2001, almost half of pregnancies were unintended. Fertility rates could be significantly reduced by providing education about overpopulation, family planning, and birth control methods, and by making birth-control devices like male/female condoms, pills, and intrauterine devices easily available. At the same time, other countries may roll back access to contraception, as has happened recently in Afghanistan. Or they may implement pro-natalist policies, like those seen in much of Europe where governments are concerned with sub-replacement fertility. Any of these changes could affect fertility rates and therefore alter forecasts of population growth.
At the same time, other factors could affect mortality rates, which would also alter population forecasts. Death rates could fall unexpectedly due to advances in medicine or innovations that stretch resources so population can continue to grow past what seemed like intractable resource limits. For example, in the mid-20th century, the Green Revolution in agriculture dramatically increased available food by spreading farming technology like fertilizer and increasing efficiency in agriculture. In the future, production might be increased by innovations such as genetically modified crops, more efficiently employing agricultural technology, and aquaculture.
At the same time, death rates can also increase unexpectedly due to disease, wars, and other mass catastrophes. According to some scenarios, disasters triggered by the growing population’s demand for scarce resources will eventually lead to a sudden population crash, or even a Malthusian catastrophe, where overpopulation would compromise global food security and lead to mass starvation .
The Green Revolution
The Green Revolution was a period of rapid technological innovation in agricultural, which made food resources more widely available than expected and thus reduced the global mortality rate. This type of unanticipated change can reduce the accuracy of population forecasts.
17.2.4: Malthus’ Theory of Population Growth
Malthus believed that if a population is allowed to grow unchecked, people will begin to starve and will go to war over increasingly scarce resources.
Learning Objective
Discuss Malthus’s controversial theory on population growth, in terms of the concept of “moral restraint”
Key Points
- Thomas Malthus warned that without any checks, population would theoretically grow at an exponential rate, rapidly exceeding its ability to produce resources to support itself.
- Malthus argued that an exponentially growing population will self-correct through war, famine, and disease.
- Malthus cautioned that in order to avoid catastrophe such as famine and war, people should enact deliberate population control, such as birth control and celibacy.
- Malthusian catastrophes refer to naturally occurring checks on population growth such as famine, disease, or war.
- These Malthusian catastrophes have not taken place on a global scale due to progress in agricultural technology. However, many argue that future pressures on food production, combined with threats such as global warming, make overpopulation a still more serious threat in the future.
Key Terms
- Malthusian catastrophes
-
Malthusian catastrophes are naturally occurring checks on population growth such as famine, disease, or war.
- exponential growth
-
The growth in the value of a quantity, in which the rate of growth is proportional to the instantaneous value of the quantity; for example, when the value has doubled, the rate of increase will also have doubled. The rate may be positive or negative.
- carrying capacity
-
The number of individuals of a particular species that an environment can support.
Example
- Advocates of Malthusian theory point to epidemics that diminished urban populations after early periods of urbanization as evidence that Mathus’ predictions were correct. For example, from 1918-1922, an estimated 75,000,000 people worldwide are thought to have died from an influenza epidemic. Malthusians would cite this as a natural check on populations that were outpacing natural resource availability.
Early in the 19th century, the English scholar Reverend Thomas Malthus published “An Essay on the Principle of Population.” He wrote that overpopulation was the root of many problems industrial European society suffered from—poverty, malnutrition, and disease could all be attributed to overpopulation. According to Malthus, this was a mathematical inevitability. Malthus observed that, while resources tended to grow arithmetically, populations exhibit exponential growth. Thus, if left unrestricted, human populations would continue to grow until they would become too large to be supported by the food grown on available agricultural land. In other words, humans would outpace their local carrying capacity, the capacity of ecosystems or societies to support the local population.
As a solution, Malthus urged “moral restraint. ” That is, he declared that people must practice abstinence before marriage, forced sterilization where necessary, and institute criminal punishments for so-called unprepared parents who had more children than they could support. Even in his time, this solution was controversial.
According to Malthus, the only alternative to moral restraint was certain disaster: if allowed to grow unchecked, population would outstrip available resources, resulting in what came to be known as Malthusian catastrophes: naturally occurring checks on population growth such as famine, disease, or war.
Over the two hundred years following Malthus’s projections, famine has overtaken numerous individual regions. Proponents of this theory, Neo-Malthusians, state that these famines were examples of Malthusian catastrophes. On a global scale, however, food production has grown faster than population due to transformational advances in agricultural technology. It has often been argued that future pressures on food production, combined with threats to other aspects of the earth’s habitat such as global warming, make overpopulation a still more serious threat in the future.
Overpopulated Urban Slums
Malthusians would cite epidemics and starvation in overpopulated urban slums, like this one in Cairo, as natural checks on growing populations that have exceeded the carrying capacities of their local environments.
17.2.5: Demographic Transition Theory
Demographic transition theory outlines five stages of change in birth and death rates to predict the growth of populations.
Learning Objective
Break down the demographic transition model/theory into five recognizable stages based on how countries reach industrialization
Key Points
- Demographic transition theory suggests that populations grow along a predictable five-stage model.
- In stage 1, pre-industrial society, death rates and birth rates are high and roughly in balance, and population growth is typically very slow and constrained by the available food supply.
- In stage 2, that of a developing country, the death rates drop rapidly due to improvements in food supply and sanitation, which increase life spans and reduce disease.
- In stage 3, birth rates fall due to access to contraception, increases in wages, urbanization, increase in the status and education of women, and increase in investment in education. Population growth begins to level off.
- In stage 4, birth rates and death rates are both low. The large group born during stage two ages and creates an economic burden on the shrinking working population.
- In stage 5 (only some theorists acknowledge this stage—others recognize only four), fertility rates transition to either below-replacement or above-replacement.
Key Term
- demographic transition theory
-
Describes four stages of population growth, following patterns that connect birth and death rates with stages of industrial development.
Whether you believe that we are headed for environmental disaster and the end of human existence as we know it, or you think people will always adapt to changing circumstances, we can see clear patterns in population growth. Societies develop along a predictable continuum as they evolve from unindustrialized to postindustrial. Demographic transition theory (Caldwell and Caldwell 2006) suggests that future population growth will develop along a predictable four- or five-stage model.
Stage 1
In stage one, pre-industrial society, death rates and birth rates are high and roughly in balance. An example of this stage is the United States in the 1800s. All human populations are believed to have had this balance until the late 18th century, when this balance ended in Western Europe. In fact, growth rates were less than 0.05% at least since the Agricultural Revolution over 10,000 years ago.
Population growth is typically very slow in this stage, because the society is constrained by the available food supply; therefore, unless the society develops new technologies to increase food production (e.g. discovers new sources of food or achieves higher crop yields), any fluctuations in birth rates are soon matched by death rates.
Stage 2
In stage two, that of a developing country, the death rates drop rapidly due to improvements in food supply and sanitation, which increase life spans and reduce disease. Afghanistan is currently in this stage.
The improvements specific to food supply typically include selective breeding and crop rotation and farming techniques. Other improvements generally include access to technology, basic healthcare, and education. For example, numerous improvements in public health reduce mortality, especially childhood mortality. Prior to the mid-20th century, these improvements in public health were primarily in the areas of food handling, water supply, sewage, and personal hygiene. Another variable often cited is the increase in female literacy combined with public health education programs which emerged in the late 19th and early 20th centuries.
In Europe, the death rate decline started in the late 18th century in northwestern Europe and spread to the south and east over approximately the next 100 years. Without a corresponding fall in birth rates this produces an imbalance, and the countries in this stage experience a large increase in population.
Stage 3
In stage three, birth rates fall. Mexico’s population is at this stage. Birth rates decrease due to various fertility factors such as access to contraception, increases in wages, urbanization, a reduction in subsistence agriculture, an increase in the status and education of women, a reduction in the value of children’s work, an increase in parental investment in the education of children and other social changes. Population growth begins to level off. The birth rate decline in developed countries started in the late 19th century in northern Europe.
While improvements in contraception do play a role in birth rate decline, it should be noted that contraceptives were not generally available nor widely used in the 19th century and as a result likely did not play a significant role in the decline then.
It is important to note that birth rate decline is caused also by a transition in values; not just because of the availability of contraceptives.
Stage 4
During stage four there are both low birth rates and low death rates. Birth rates may drop to well below replacement level as has happened in countries like Germany, Italy, and Japan, leading to a shrinking population, a threat to many industries that rely on population growth. Sweden is considered to currently be in Stage 4.
As the large group born during stage two ages, it creates an economic burden on the shrinking working population. Death rates may remain consistently low or increase slightly due to increases in lifestyle diseases due to low exercise levels and high obesity and an aging population in developed countries.
By the late 20th century, birth rates and death rates in developed countries leveled off at lower rates.
Stage 5 (Debated)
Some scholars delineate a separate fifth stage of below-replacement fertility levels. Others hypothesize a different stage five involving an increase in fertility.
The United Nations Population Fund (2008) categorizes nations as high-fertility, intermediate-fertility, or low-fertility. The United Nations (UN) anticipates the population growth will triple between 2011 and 2100 in high-fertility countries, which are currently concentrated in sub-Saharan Africa.
For countries with intermediate fertility rates (the United States, India, and Mexico all fall into this category), growth is expected to be about 26 percent. And low-fertility countries like China, Australia, and most of Europe will actually see population declines of approximately 20 percent.
Demographic Transition Overview
Conclusions
As with all models, this is an idealized picture of population change in these countries. The model is a generalization that applies to these countries as a group and may not accurately describe all individual cases. The extent to which it applies to less-developed societies today remains to be seen. Many countries such as China, Brazil and Thailand have passed through the Demographic Transition Model (DTM) very quickly due to fast social and economic change. Some countries, particularly African countries, appear to be stalled in the second stage due to stagnant development and the effect of AIDS.
17.3: Urbanization and the Development of Cities
17.3.1: The Earliest Cities
Early cities arose in a number of regions, and are thought to have developed for reasons of agricultural productivity and economic scale.
Learning Objective
Summarize the various beginnings of cities, from centers of agriculture to areas of protection, and the factors they need to be successful
Key Points
- The very first cities were founded in Mesopotamia after the Neolithic Revolution, around 7500 BCE.
- Agriculture is believed to be a pre-requisite for cities, which help preserve surplus production and create economies of scale.
- Cities reduced transport costs for goods, people, and ideas by bringing them all together in one spot.
Key Terms

The Neolithic Revolution or Neolithic Demographic Transition, sometimes called the Agricultural Revolution, was the world’s first historically verifiable revolution in agriculture.
- Old World
-
The known world before the discovery of the Americas.
Examples
- Rome is a well-known example of an ancient city that served political and commercial functions, as well as acting as a cultural and social center.
- Many early cities were surrounded by patrolled walls, demonstrating the importance of protection in urban centers of early civilizations.
Early cities developed in a number of regions, from Mesopotamia to Asia to the Americas. The very first cities were founded in Mesopotamia after the Neolithic Revolution, around 7500 BCE. Mesopotamian cities included Eridu, Uruk, and Ur. Early cities also arose in the Indus Valley and ancient China. Among the early Old World cities, one of the largest was Mohenjo-daro, located in the Indus Valley (present-day Pakistan); it existed from about 2600 BCE, and had a population of 50,000 or more. In the ancient Americas, the earliest cities were built in the Andes and Mesoamerica, and flourished between the 30th century BCE and the 18th century BCE.
Ancient cities were notable for their geographical diversity, as well as their diversity in form and function. Theories that attempt to explain ancient urbanism by a single factor, such as economic benefit, fail to capture the range of variation documented by archaeologists. Excavations at early urban sites show that some cities were sparsely populated political capitals, others were trade centers, and still other cities had a primarily religious focus. Some cities had large dense populations, whereas others carried out urban activities in the realms of politics or religion without having large associated populations. Some ancient cities grew to be powerful capital cities and centers of commerce and industry, situated at the centers of growing ancient empires. Examples include Alexandria and Antioch of the Hellenistic civilization, Carthage, and ancient Rome and its eastern successor, Constantinople (later Istanbul).
The Formation of Cities
Why did cities form in the first place? There is insufficient evidence to assert what conditions gave rise to the first cities, but some theorists have speculated on what they consider pre-conditions and basic mechanisms that could explain the rise of cities. Agriculture is believed to be a pre-requisite for cities, which help preserve surplus production and create economies of scale. The conventional view holds that cities first formed after the Neolithic Revolution, with the spread of agriculture. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and settle near others who lived by agricultural production. Agriculture yielded more food, which made denser human populations possible, thereby supporting city development. Farming led to dense, settled populations, and food surpluses that required storage and could facilitate trade. These conditions seem to be important prerequisites for city life. Many theorists hypothesize that agriculture preceded the development of cities and led to their growth.
A good environment and strong social organization are two necessities for the formation of a successful city. A good environment includes clean water and a favorable climate for growing crops and agriculture. A strong sense of social organization helps a newly formed city work together in times of need, and it allows people to develop various functions to assist in the future development of the city (for example, farmer or merchant). Without these two common features, as well as advanced agricultural technology, a newly formed city is not likely to succeed.
Cities may have held other advantages, too. For example, cities reduced transport costs for goods, people, and ideas by bringing them all together in one spot. By reducing these transaction costs, cities contributed to worker productivity. Finally, cities likely performed the essential function of providing protection for people and the valuable things they were beginning to accumulate. Some theorists hypothesize that people may have come together to form cities as a form of protection against marauding barbarian armies.
17.3.2: Preindustrial Cities
Preindustrial cities had important political and economic functions and evolved to become well-defined political units.
Learning Objective
Examine the growth of preindustrial cities as political units, as well as how trade routes allowed certain cities to expand and grow
Key Points
- Preindustrial cities were political units, like today’s states. They offered freedom from rural obligations to lord and community.
- In the early modern era, larger capital cities benefited from new trade routes and grew even larger.
- While the city-states, or poleis, of the Mediterranean and Baltic Sea languished from the 16th century, Europe’s larger capitals benefited from the growth of commerce following the emergence of an Atlantic trade.
Key Terms
- Preindustrial cities
-
While ancient cities may have arisen organically as trading centers, preindustrial cities evolved to become well defined political units.
- rural obligations
-
For people during the medieval era, cities offered a newfound freedom from rural obligations. City residence brought freedom from customary rural obligations to lord and community.
- lord
-
A titled nobleman or aristocrat
Example
- London is an example of a city that was well established in the preindustrial era as a political and economic center.
Cities as Political Centers
While ancient cities may have arisen organically as trading centers, preindustrial cities evolved to become well defined political units, like today’s states. During the European Middle Ages, a town was as much a political entity as a collection of houses. However, particular political forms varied. In continental Europe, some cities had their own legislatures. In the Holy Roman Empire, some cities had no other lord than the emperor. In Italy, medieval communes had a state-like power. In exceptional cases like Venice, Genoa, or Lübeck, cities themselves became powerful states, sometimes taking surrounding areas under their control or establishing extensive maritime empires. Similar phenomena existed elsewhere, as in the case of Sakai, which enjoyed a considerable autonomy in late medieval Japan.
For people during the medieval era, cities offered a newfound freedom from rural obligations. City residence brought freedom from customary rural obligations to lord and community (hence the German saying, “Stadtluft macht frei,” which means “City air makes you free”). Often, cities were governed by their own laws, separate from the rule of lords of the surrounding area.
Trade Routes
Not all cities grew to become major urban centers. Those that did often benefited from trade routes—in the early modern era, larger capital cities benefited from new trade routes and grew even larger. While the city-states, or poleis, of the Mediterranean and Baltic Sea languished from the 16th century, Europe’s larger capitals benefited from the growth of commerce following the emergence of an Atlantic trade. By the early 19th century, London had become the largest city in the world with a population of over a million, while Paris rivaled the well-developed regional capital cities of Baghdad, Beijing, Istanbul, and Kyoto. But most towns remained far smaller places—in 1500 only about two dozen places in the world contained more than 100,000 inhabitants. As late as 1700 there were fewer than 40, a figure which would rise thereafter to 300 in 1900. A small city of the early modern period might have contained as few as 10,000 inhabitants.
17.3.3: Industrial Cities
During the industrial era, cities grew rapidly and became centers of population growth and production.
Learning Objective
Discuss the problems urbanization created for newly formed cities
Key Points
- Rapid growth brought urban problems, and industrial-era cities were rife with dangers to health and safety.
- Poor sanitation and communicable diseases were among the greatest causes of death among urban working class populations.
- In the 19th century, better sanitation led to improved health conditions.
Key Terms
- industrial cities
-
Rapid growth brought urban problems, and industrial-era cities were rife with dangers to health and safety. Quickly expanding industrial cities could be quite deadly, full of contaminated water and air, and communicable diseases.
- industrial era
-
During the industrial era, cities grew rapidly and became centers of population and production.
Example
- Upton Sinclair’s The Jungle chronicles the dangerous living conditions endured by immigrant factory workers in the early-1900s, a period of rapid urbanization in the U.S. The book’s protagonist immigrates from Eastern Europe to Chicago in search of employment and eventual prosperity, but instead finds dangerous assembly lines, unsanitary water, and cramped tenement buildings.
During the industrial era, cities grew rapidly and became centers of population and production. The growth of modern industry from the late 18th century onward led to massive urbanization and the rise of new, great cities, first in Europe, and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. In 1800, only 3% of the world’s population lived in cities. Since the industrial era, that figure, as of the beginning of the 21st century, has risen to nearly 50%. The United States provides a good example of how this process unfolded; from 1860 to 1910, the invention of railroads reduced transportation costs and large manufacturing centers began to emerge in the United States, allowing migration from rural to urban areas.
Rapid growth brought urban problems, and industrial-era cities were rife with dangers to health and safety. Rapidly expanding industrial cities could be quite deadly, and were often full of contaminated water and air, and communicable diseases. Living conditions during the Industrial Revolution varied from the splendor of the homes of the wealthy to the squalor of the workers. Poor people lived in very small houses in cramped streets. These homes often shared toilet facilities, had open sewers, and were prone to epidemics exacerbated by persistent dampness. Disease often spread through contaminated water supplies.
In the 19th century, health conditions improved with better sanitation, but urban people, especially small children, continued to die from diseases spreading through the cramped living conditions. Tuberculosis (spread in congested dwellings), lung diseases from mines, cholera from polluted water, and typhoid were all common. The greatest killer in the cities was tuberculosis (TB). Archival health records show that as many as 40% of working class deaths in cities were caused by tuberculosis.

17.3.4: The Structure of Cities
Urban structure is the arrangement of land use, explained using different models.
Learning Objective
Analyze, using human ecology theory, the similarities and differences between the various urban structure models, such as grid model, sectoral model and concentric ring model, among others
Key Points
- In the grid model of cities, land is divided by streets that run at right angles to each other, forming a grid. This model promotes development.
- The concentric ring model describes the city as an ecosystem in which residents sort themselves into a series of rings based on class and occupation. This model’s general applicability has been challenged.
- Urban structure can also describe the location of the central business district, industrial parks, or urban open spaces.
- The sectoral model says the city develops in wedge-shaped sectors instead of rings: certain areas of a city are more attractive for various activities, which flourish and expand outward in a wedge.
- The multiple nuclei model assumes that car ownership granted people more mobility and led the the development of specialized regional centers within cities.
- The irregular pattern model was developed to better explain urban structure in the Third World. It attempts to model the lack of planning or construction found in many rapidly built Third World cities.
Key Terms
- Human Ecology
-
Human ecology described the city as analogous to an ecosystem, with natural processes of adaptation and assimilation.
- urban open space
-
In land use planning, urban open space is open space areas for parks, green spaces, and other open areas.
- central business district
-
The central area of a city in which a concentration of certain retail and business activities takes place, especially in older cities with rail transportation.
Examples
- Washington, D.C. is an example of a city that was planned in a classic European style, with streets radiating off of a central point. Midtown Manhattan, by contrast, employs a more modern grid pattern to create easily navigable and divisible blocks.
- Areas with dispersed, rural populations have few major cities, since the small populations do not have a great demand for goods and services. For example, Cheyenne, Wyoming is an extremely small urban center compared to Chicago, Illinois. This dispersion of cities illustrates central place theory.
Urban Structure Models
Grid
In grid models, land is divided by streets intersect at right angles, forming a grid. Grid plans are more common in North American cities than in Europe, where older cities tend to be build on streets that radiate out from a central square or structure of cultural significance. Grid plans facilitate development because developers can subdivide and auction off large parcels of land. The geometry yields regular lots that maximize use and minimize boundary disputes. However, grids can be dangerous because long, straight roads allow faster automobile traffic. In the 1960s, urban planners moved away from grids and began planning suburban developments with dead ends and cul-de-sacs.
Concentric Ring Model
The concentric ring model was postulated in 1924 by sociologist Ernest Burgess, based on his observations of Chicago . It draws on human ecology theories, which compared the city to an ecosystem, with processes of adaptation and assimilation. Urban residents naturally sort themselves into appropriate rings, or ecological niches, depending on class and cultural assimilation. The innermost ring represents the central business district (CBD), called Zone A. . It is surrounded by a zone of transition (B), which contains industry and poorer-quality housing. The third ring (C) contains housing for the working-class—the zone of independent workers’ homes. The fourth ring (D) has newer and larger houses occupied by the middle-class. The outermost ring (E), or commuter’s zone, is residential suburbs.
Toronto’s Central Business District
Skyscrapers populate Toronto’s central business district
Concentric Zone Model
The Concentric Ring Model described the city as a series of concentric rings, each home to a different group and social function.
This model’s general applicability has been challenged. It describes an American geography in which the inner city is poor while suburbs are wealthy—elsewhere, the converse is the norm. In new, western U.S. cities such as Los Angeles, advances in transportation and communication have blurred these “zones. ” Further, the model fails to account for topographical and physical features of the landscape. Even in Chicago, the concentric rings were semi-circles, interrupted by Lake Michigan.
Sectoral
In 1939, the economist Homer Hoyt adapted the concentric ring model by proposing that cities develop in wedge-shaped sectors instead of rings. Certain areas of a city are more attractive for various activities, whether by chance or geographic/environmental reasons. As these activities flourish and expand outward, they form wedges, becoming city sectors . Like the concentric ring model, Hoyt’s sectoral model has been criticized for ignoring physical features and new transportation patterns that restrict or direct growth.
Hoyt’s Sectoral Model of Urban Growth
In Hoyt’s model, cities grow in wedge-shaped sectors radiating from the center.
Multiple Nuclei
The multiple nuclei model was developed in 1945 to explain city formation after the spread of the automobile. People have greater movement due to increased car ownership, allowing for the specialization of regional centers. A city contains more than one center around which activities revolve. Some activities are attracted to particular nodes while others try to avoid them. For example, a university node may attract well-educated residents, pizzerias, and bookstores, whereas an airport may attract hotels and warehouses. Incompatible activities will avoid clustering in the same area.
Irregular Pattern
The irregular pattern model was developed to explain urban structure in the Third World. It attempts to model the lack of planning found in many rapidly built Third World cities. This model includes blocks with no fixed order; urban structure is not related to an urban center or CBD.
Alternate Uses of “Urban Structure”
Urban structure can also refer to urban spatial structure; the arrangement of public and private space in cities and the degree of connectivity and accessibility. In this context, urban structure is concerned with the arrangement of the CBD, industrial and residential areas, and open space.
A city’s central business district (CBD), or downtown, is the commercial and often geographic heart of a city. In North America, this is referred to as “downtown” or “city center. ” The downtown area is often home to the financial district, but usually also contains entertainment and retail. CBDs usually have very small resident populations, but populations are increasing as younger professional and business workers move into city center apartments.
An industrial park is an area zoned and planned for the purpose of industrial development. They are intended to attract business by concentrating dedicated infrastructure to reduce the per-business expenses. They also set aside industrial uses from urban areas to reduce the environmental and social impact of industrial uses and to provide a distinct zone of environmental controls specific to industrial needs.
Urban open spaces provide citizens with recreational, ecological, aesthetic value. They can range from highly maintained environments to natural landscapes. Commonly open to public access, they may be privately owned. Urban open spaces offer a reprieve from the urban environment and can add ecological value, making citizens more aware of their natural surroundings and providing nature to promote biodiversity. Open spaces offer aesthetic value for citizens who enjoy nature, cultural value by providing space for concerts or art shows, and functional value—for example, by helping to control runoff and prevent flooding.
17.3.5: The Process of Urbanization
Urbanization is the process of a population shift from rural areas to cities, often motivated by economic factors.
Learning Objective
Analyze the proces of urbanization and its effects on economics and the environment in society
Key Points
- Urbanization may be driven by local and global economic and social changes, and is generally a product of modernization and industrialization.
- Urbanization has economic and environmental effects. Economically, urbanization drives up prices, especially real estate, which can force original residents to move to less-desirable neighborhoods.
- Environmentally, cities cause “heat islands”, where less vegetation and open soil raise city temperatures by 2 to 10 degrees Fahrenheit.
- Recently in developed countries, sociologists have observed suburbanization and counterurbanization, or movement away from cities, which may be driven by transportation infrastructure, or social factors like racism.
Key Terms
- counterurbanization
-
A demographic and social process whereby people move from urban areas to rural areas.
- urbanization
-
The physical growth of urban areas as a result of rural migration and even suburban concentration into cities.
- rural flight
-
A term used to describe the migratory patterns of peoples from rural areas into urban areas.
- suburbanization
-
A term used to describe the growth of areas on the fringes of major cities; one of the many causes of the increase in urban sprawl.
- gentrification
-
A shift in an urban community toward wealthier residents and/or businesses and increasing property values; often resulting in poorer residents being displaced by wealthier newcomers.
Examples
- Mexico City has undergone rapid urbanization according to the pattern seen in many developing countries. Mexico has rapidly changed from a primarily agricultural country to one with significant industry, including industrialized agriculture. Consequently, huge numbers of rural dwellers migrated to Mexico City, making it an extremely densely populated city of nearly 9 million.
- Chicago is an example of a U.S. city that has seen vast suburbanization as middle and upper class residents move to nearby suburbs. The population living within city limits is under 3 million, but the population of the “metro area,” which includes suburbs, is over 9 million.
Urbanization and rural flight
Urbanization is the process of a population shift from rural areas to cities. During the last century, global populations have urbanized rapidly:
- 13% of people lived in urban environments in the year 1900
- 29% of people lived in urban environments in the year 1950
One projection suggests that, by 2030, the proportion of people living in cities may reach 60%.
Rural and Urban World Population
Over time, the world’s population has become less rural and more urban.
Urbanization tends to correlate positively with industrialization. With the promise of greater employment opportunities that come from industrialization, people from rural areas will go to cities in pursuit of greater economic rewards.
Another term for urbanization is “rural flight. ” In modern times, this flight often occurs in a region following the industrialization of agriculture—when fewer people are needed to bring the same amount of agricultural output to market—and related agricultural services and industries are consolidated. These factors negatively affect the economy of small- and middle-sized farms and strongly reduce the size of the rural labor market. Rural flight is exacerbated when the population decline leads to the loss of rural services (such as business enterprises and schools), which leads to greater loss of population as people leave to seek those features.
As more and more people leave villages and farms to live in cities, urban growth results. The rapid growth of cities like Chicago in the late nineteenth century and Mumbai a century later can be attributed largely to rural-urban migration. This kind of growth is especially commonplace in developing countries.
Urbanization occurs naturally from individual and corporate efforts to reduce time and expense in commuting, while improving opportunities for jobs, education, housing, entertainment, and transportation. Living in cities permits individuals and families to take advantage of the opportunities of proximity, diversity, and marketplace competition. Due to their high populations, urban areas can also have more diverse social communities than rural areas, allowing others to find people like them.
Economic and Environmental Effects of Urbanization
Urbanization has significant economic and environmental effects on cities and surrounding areas. As city populations grow, they increase the demand for goods and services of all kinds, pushing up prices of these goods and services, as well as the price of land. As land prices rise, the local working class may be priced out of the real estate market and pushed into less desirable neighborhoods – a process known as gentrification.
Growing cities also alter the environment. For example, urbanization can create urban “heat islands,” which are formed when industrial and urban areas replace and reduce the amount of land covered by vegetation or open soil. In rural areas, the ground helps regulate temperatures by using a large part of the incoming solar energy to evaporate water in vegetation and soil. This evaporation, in turn, has a cooling effect. However in cities, where less vegetation and exposed soil exists, the majority of the sun’s energy is absorbed by urban structures and asphalt. During the day, cities experience higher surface temperatures because urban surfaces produce less evaporative cooling. Additional city heat is given off by vehicles and factories, as well as industrial and domestic heating and cooling units. Together, these effects can raise city temperatures by 2 to 10 degrees Fahrenheit (or 1 to 6 degrees Celsius).
Suburbanization and Counterurbanization
Recently in developed countries, sociologists have observed suburbanization and counterurbanization, or movement away from cities. These patterns may be driven by transportation infrastructure, or social factors like racism. In developed countries, people are able to move out of cities while still maintaining many of the advantages of city life (for instance, improved communications and means of transportation). In fact, counterurbanization appears most common among the middle and upper classes who can afford to buy their own homes.
Race also plays a role in American suburbanization. During World War I, the massive migration of African Americans from the South resulted in an even greater residential shift toward suburban areas. The cities became seen as dangerous, crime-infested areas, while the suburbs were seen as safe places to live and raise a family, leading to a social trend known in some parts of the world as “white flight. ” Some social scientists suggest that the historical processes of suburbanization and decentralization are instances of white privilege that have contributed to contemporary patterns of environmental racism.
In the United States, suburbanization began in earnest after World War II, when soldiers returned from war and received generous government support to finance new homes. Suburbs, which are residential areas on the outskirts of a city, were less crowded and had a lower cost of living than cities. Suburbs grew dramatically in the 1950s when the U.S. interstate highway system was built, and automobiles became affordable for middle class families. Around 1990, another trend emerged known as counterurbanization, or “exurbanization”. The wealthiest individuals began living in nice housing far in rural areas (as opposed to forms).
Suburbanization may be a new urban form.Rather than densely populated centers, cities may become more spread out, composed of many interconnected smaller towns. Interestingly, the modern U.S. experience has gone from a largely rural country, to a highly urban country, to a country with significant suburban populations.
17.3.6: U.S. Urban Patterns
The U.S. Census Bureau classifies areas as urban or rural based on population size and density.
Learning Objective
Discuss the different ways governments and society define the term “urban”
Key Points
- Different agencies and individuals define urban in different ways, but the U.S. Census Bureau’s definitions are considered standard.
- The U.S. Census Bureau defines “urban areas” as areas with a population density of at least 1,000 people per square mile and at least 2,500 total people.
- As of December, 2010, about 82% of the population of the United States lived within the boundaries of urbanized area.
Key Term
- population density
-
The average number of people who live on each square mile (or kilometer) of land.
Example
- Boise, Idaho is an example of an urban area that is officially defined as urban by U.S. Census Bureau criteria, but in many ways differs from larger, more recognizable cities like New York and Los Angeles. Small cities like Boise are defined by having at least 1,000 people per square mile and over 2,500 people overall. Usually, this type of population center is associated with a cluster of industrial and cultural enterprises.
Different international, national, and local agencies may define “urban” in various ways. For example, city governments often use political boundaries to delineate what counts as a city. Other definitions may consider total population size or population density. Different definitions may also set various thresholds, so that in some cases, a town of just 2,500 may count as an urban city, whereas in other contexts, a city may be defined as having at least 50,000 people. Other agencies may define “urban” based on land use: places count as urban if they are built up with residential neighborhoods, industrial sites, railroad yards, cemeteries, airports, golf courses, and similar areas. Using this sort of definition, in 1997, the U.S. Department of Agriculture tallied over 98,000,000 acres of “urban” land.
In spite of these competing definitions, in the United States “urban” is officially defined following guidelines set by the U.S. Census Bureau. The Census Bureau defines “urban areas” as areas with a population density of at least 1,000 people per square mile and at least 2,500 total people. Urban areas are delineated without regard to political boundaries. Because this definition does not consider political boundaries, it is often used as a more accurate gauge of the size of a city than the number of people who live within the city limits. Often, these two numbers are not the same. For example, the city of Greenville, South Carolina has a city population under 60,000 and an urbanized area population of over 300,000, while Greensboro, North Carolina has a city population over 200,000 and an urbanized area population of around 270,000. That means that Greenville is actually “larger” for some intents and purposes, but not for others, such as taxation, local elections, etc.
As of December, 2010, about 82% of the population of the United States lived within the boundaries of urbanized area. Combined, these areas occupy about 2% of the land area of the United States. The majority of urbanized area residents are suburbanites; core central city residents make up about 30% of the urbanized area population (about 60 million out of 210 million). In the United States, the largest urban area is New York City, with over 8 million people within the city limits and over 19 million in the urban area. The next five largest urban areas in the United States are Los Angeles, Chicago, Washington, D.C., Philadelphia, and Boston.

17.3.7: The Rural Rebound
During the 1970s and again in the 1990s, the rural population rebounded in what appeared to be a reversal of urbanization.
Learning Objective
Explain the rural rebound and how it contributes to the suburbanization of society
Key Points
- Much of the “rural” rebound was driven by suburbanization, which is the movement of people from cities to surrounding suburbs, ex-urbs, or edge cities.
- Suburbanization may be driven by white flight.
- Counterurbanization refers, broadly, to movement away from the city, which may include urban-to-rural migration and suburbanization.
- Counterurbanization has created shrinking cities and attempts to better control urban growth.
Key Terms
- white flight
-
The large-scale migration of whites of various European ancestries, from racially mixed urban regions to more racially homogeneous suburban areas.
- ex-urbs
-
The expression exurb (for “extra-urban”) was coined by Auguste Comte Spectorsky in his 1955 book The Exurbanites to describe the ring of prosperous communities beyond the suburbs that are commuter towns for an urban area.
- counterurbanization
-
Counterurbanisation is a demographic and social process whereby people move from urban areas to rural areas.
Example
- Population trends in Boston, Massachusetts show the modern process of suburbanization. Since the 1950s, many middle and upper class individuals have moved to nearby suburbs to escape crime and urban decay. Since the 1990s, however, a new trend among middle and upper class residents is to move to New Hampshire. While the trend is not hugely widespread, it is clearly motivated by attempts to avoid high tax rates and urban crowding, and is enabled only by modern communications and transportation technology. It is thus a new, modern form of suburbanization.
The rural rebound refers to the movement away from cities to rural and suburban areas. Urbanization tends to occur along with modernization, yet in the most developed countries many cities are now beginning to lose population. In the United States in the 1970s, demographers observed that the rural population was actually growing faster than urban populations, a phenomenon they labeled the “rural rebound. ” This trend reversed in the 1980s, due in part to a recession that hit farmers particularly hard. But again in the 1990s, rural populations appeared to be gaining at the expense of cities. Indeed, in the last 50 years, about 370 cities worldwide with more than 100,000 residents have undergone population losses of more than 10%, and more than 25% of the depopulating cities are in the United States.
Rather than moving to rural areas, most participants in the so-called the rural rebound migrated into new, rapidly growing suburbs. The rural rebound, then, may be more evidence of the importance of suburbanization as a new urban form in the most developed countries.
Suburbanization
Suburbanization is a general term that refers to the movement of people from cities to surrounding areas. However, the suburbanization that took place after 1970 was different from the suburbanization that had occurred earlier, after World War II. In this more recent wave of suburbanization, people moved beyond the nearby suburbs to farther-away towns. Sociologists have invented several new categories to describe these new types of suburban towns; two of the most notable are ex-urbs and edge cities.
The expression exurb (for “extra-urban”) refers to a ring of prosperous communities beyond a city’s suburbs. Often, these communities are commuter towns or bedroom communities. Commuter towns are primarily residential; most of the residents commute to jobs in the city. They are sometimes called bedroom communities because residents spend their days away in the cities and only come home to sleep. In general, commuter towns have little commercial or industrial activity of their own, though they may contain some retail centers to serve the daily needs of residents. Although most exurbs are commuter towns, most commuter towns are not exurban.
Exurbs vary in wealth and education level. In the United States, exurban areas typically have much higher college education levels than closer-in suburbs, though this is not necessarily the case in other countries. They typically have average incomes much higher than nearby rural counties, reflecting the urban wages of their residents. Although some exurbs are quite wealthy even compared to nearer suburbs or the city itself, others have higher poverty levels than suburbs nearer the city. This may happen especially where commuter towns form because workers in a region cannot afford to live where they work and must seek residency in another town with a lower cost of living. For example, during the “dot com” bubble of the late twentieth century, housing prices in California cities skyrocketed, spawning exurban growth in adjacent counties.
White Flight
Sociologists have posited many explanations for counterurbanization, but one of the most debated is whether suburbanization is driven by white flight. The term white flight was coined in the mid-twentieth century to describe suburbanization and the large-scale migration of whites of various European ancestries, from racially mixed urban regions to more racially homogeneous suburban regions. During the first half of the twentieth century, discriminatory housing policies often prevented blacks from moving to suburbs; banks and federal policy made it difficult for blacks to get the mortgages they needed to buy houses, and communities used restrictive housing covenants to exclude minorities.
White flight during this period contributed to urban decay, a process whereby a city, or part of a city, falls into disrepair and decrepitude. Symptoms of urban decay include depopulation, abandoned buildings, high unemployment, crime, and a desolate, inhospitable landscape. White flight contributed to the draining of cities’ tax bases when middle-class people left, exacerbating urban decay caused in part by the loss of industrial and manufacturing jobs as they moved into rural areas or overseas where labor was cheaper.
More recently, the concept has been extended to newer forms of suburbanization, including migration from urban to rural areas and to exurbs. In a similar vein, some demographers have described the rural rebound, and the newest waves of suburbanization, as a form of ethnic balkanization, in which different ethnic groups (not only whites) sort themselves into racially homogeneous communities. These phenomena, however, are not so clearly driven by the restrictive policies, laws, and practices that drove the white flight of the first half of the century.

Suburban neighborhoods often feature large, manicured lawns.
17.3.8: Models of Urban Growth
Models of urban growth try to balance the advantages and disadvantages of cities’ large sizes.
Learning Objective
Summarize the various theories of urban growth and the implications each theory has for today’s society
Key Points
- The growth machine theory of urban growth says urban growth is driven by a coalition of interest groups who all benefit from continuous growth and expansion. Thus, the growth of cities is a social phenomenon.
- Urban sprawl results when cities grow uncontrolled, expanding into rural land and making walking, public transit, or bicycling impractical.
- Critics of urban life often focus on urban decay, which may be self-perpetuating, according to the broken windows theory.
- Urban renewal attempts to counter urban decay and restore growth.
- The New Urbanism and smart growth movements both challenge the value of urban growth and expansion, and they try to improve urban life by keeping it on a human scale.
Key Terms
- New Urbanism
-
New Urbanism is an urban design movement that promotes walkable neighborhoods that contain a range of housing and job types.
- urban renewal
-
Urban renewal refers to programs of land redevelopment in areas of moderate- to high-density urban land use.
- smart growth
-
Smart growth programs draw urban growth boundaries to keep urban development dense and compact.
Example
- Harlem, New York is an example of a neighborhood with a long history of urban growth and decay. Around the 1920s, Harlem was associated with the Harlem Renaissance, a period of concentrated artistic and cultural innovation and rising standards of living that might now be considered an era of urban renewal. Since that period, the neighborhood experienced urban decay and became a hotbed of crime and poverty. In recent years, various organizations have sought to renew the neighborhood by encouraging the development of new residences and businesses.
Cities are dynamic places—they grow, shrink, and change. Sociologists have developed different theories for thinking about how urban populations change.
Growth Machine Theory
The growth machine theory of urban growth says urban growth is driven by a coalition of interest groups who all benefit from continuous growth and expansion. First articulated by Molotch in 1976, growth machine theory took the dominant convention of studying urban land use and turned it on its head.
The field of urban sociology had been dominated by the idea that cities were basically containers for human action, in which actors competed among themselves for the most strategic parcels of land, and the real estate market reflected the state of that competition. Growth machine theory reversed the course of urban theory by pointing out that land parcels were not empty fields awaiting human action, but were associated with specific interests—commercial, sentimental, and psychological. In other words, city residents were not simply competing for parcels of land; they were also trying to fulfill their particular interests and achieve specific goals. In particular, cities are shaped by the real estate interests of people whose properties gain value when cities grow. These actors make up what Molotch termed “the local growth machine. “
Urban Sprawl
Whether explained by older theories of natural processes or by growth machine theory, the fact of urban growth is undeniable: throughout the twentieth century, cities have grown rapidly. In some cases, that growth has been poorly controlled, resulting in a phenomenon known as urban sprawl. Urban sprawl entails the growth of a city into low-density and auto-dependent rural land, high segregation of land use (e.g., retail sections placed far from residential areas, often in large shopping malls or retail complexes), and design features that encourage car dependency.
Urban sprawl’s segregated land use means that the places where people live, work, shop, and relax are far from one another, which usually makes walking, public transit, or bicycling impractical. As a result, residents must use an automobile. Urban sprawl tends to include low population density: single family homes on large lots instead of apartment buildings, single story or low-rise buildings instead of high-rises, extensive lawns and surface parking lots, and so on.
Critics of urban sprawl argue that it creates an inhospitable urban environment and that it encroaches on rural land, potentially driving up land prices and displacing farmers or other rural residents. Urban sprawl is also associated with negative environmental and public health effects, many of which are related to automobile dependence: increases in personal transportation costs, air pollution and reliance on fossil fuel, increases in traffic accidents, delays in emergency medical services response times, and decreases in land and water quantity and quality.
Urban Decay
Some have suggested that urban sprawl is driven by consumer preference; people prefer to live in lower density, quieter, more private communities that they perceive as safer and more relaxed than urban neighborhoods. Such preferences echo a common strain of criticism of urban life, which tends to focus on urban decay. According to these critics, urban decay is caused by the excessive density and crowding of cities, and it drives out residents, creating the conditions for urban sprawl.
BROKEN WINDOWS
An alternative theory suggests that density does not cause crime, and crime does not cause people to leave the city; when people leave, city neighborhoods are abandoned and neglected, resulting in crime and decay. This theory, known as the “broken windows theory,” argues that small indicators of neglect, such as broken windows and unkempt lawns, promote a feeling that an area is in a state of decay. Anticipating decay, people likewise fail to maintain their own properties.
RESPONSES TO DECAY
Cities have responded to urban decay and urban sprawl by launching urban renewal programs. Two specific types of urban renewal programs—New Urbanism and smart growth—attempt to make cities more pleasant and livable.
Smart growth programs draw urban growth boundaries to keep urban development dense and compact. In addition to increasing the density of cities, urban growth boundaries can protect the surrounding farmland and wild areas. Smart growth programs often incorporate transit-oriented development goals to encourage effective public transit systems and make bicyclers and pedestrians more comfortable.
New Urbanism is an urban design movement that promotes walkable neighborhoods with a range of housing options and job types. As an approach to urban planning, it encompasses principles such as traditional neighborhood design and transit-oriented development. A neighborhood designed along New Urbanist principles would have a discernible center (such as a square or a green) with a transit stop nearby. Most homes would be within a five-minute walk of the center and would provide a variety of housing options, including houses, row houses, and apartments to encourage the mixing of younger and older people, singles and families, and poor and wealthy.

17.4: Urban Life
17.4.1: Sociological Perspectives on Urban Life
Urban sociology is the study of social life and interactions in urban areas, using methods ranging from statistical analysis to ethnography.
Learning Objective
Explain urbanization in terms of functionalism and what the Chicago School understood to be some of the causes of urban social problems at that time
Key Points
- Georg Simmel is widely considered to be the father of urban sociology, as he pioneered studies of the interrelation of space and social interaction.
- Urban sociology attempts to account for the interrelation of subcultures in urban areas, as well as the internal structures of segments of society.
- Like biological systems, urban subgroups are dependent on one another for healthy functioning and are also dynamic—that is, they flourish and decline based on political, economic, and social tides.
Key Terms
- subculture
-
A portion of a culture distinguished from the larger society around it by its customs or other features.
- alienation
-
Emotional isolation or dissociation.
Example
- Nels Anderson’s 1923 study of “The Hobo” sought to explain the internal structure of hobo communities in Chicago. This is one of the earliest examples of a subcultural study that explained the organization of urban subgroups as opposed to strictly highlighting the disorganization that accompanied urbanization.
Urban sociology is the sociological study of life and human interaction in metropolitan areas. It is a well-established subfield of sociology that seeks to study the structures, processes, changes and problems of urban areas and to subsequently provide input for planning and policymaking. In other words, it is the sociological study of cities and their role in the development of society. Like most areas of sociology, urban sociologists use statistical analysis, observation or ethnography, social theory, interviews, and other methods to study a range of topics, including migration, economic and demographic trends, as well as things like poverty, race relations, crime, sexuality, and many other phenomena that surface in dynamic cities.
After the Industrial Revolution sociologists such as Max Weber and Georg Simmel began to focus on the accelerating process of urbanization and the effects it had on feelings of social alienation and anonymity. Notably, Georg Simmel is widely considered to be the father of urban sociology for his contributions to the field in in works such as The Metropolis and Mental Life, published in 1903.
The Chicago School
The Chicago School of Sociology is widely credited with institutionalizing urban sociology as a disciplinary sub-field through pioneering studies of urban spaces and social interactions . This group of sociologists studied the built urban environment in Chicago through the early twentieth century and they have left a lasting impact on the field, as subsequent researchers adopted qualitative methods such as ethnography and land-use mapping to theorize urban phenomena. The Chicago School combined sociological and anthropological theories to understand the interrelation of urban structures and micro-interactions in cities. The Chicago School sought to provide subjective meaning to how humans interact under structural, cultural and social conditions.
The Chicago School of Sociology
The Chicago School of Sociology, developed at the University of Chicago, is credited with developing modern urban sociology as researchers worked to elucidate patterns of urban life.
Scholars of the Chicago School originally focused around one integral question: How did an increase in urbanism during the time of the Industrial Revolution contribute to the magnification of then-contemporary social problems? Sociologists centered in Chicago due to its “tabula rasa” state (people’s minds before they receive impressions gained from experience), having expanded from a small town of 10,000 in 1860 to a urban metropolis of two million in the next half decade. Along with this expansion came many of the era’s emerging social problems, ranging from issues of homelessness and poor living conditions to the low-wage and long-hour work periods that many European immigrants faced upon arrival in the city. Furthermore, unlike many other metropolitan areas, Chicago did not expand outward at the edges as predicted by early expansionist theorists, but instead reformatted the space available in a concentric ring pattern. As with many modern cities the business district that occupied the city center was surrounded by slums and blighted neighborhoods, which were further surrounded by working class homes and the early forms of the modern suburbs. Urban theorists suggested that these spatially-defined regions helped to solidify and isolate class relations within the modern city, moving the middle class away from the urban core and into the privatized environment of the outer suburbs.
Due to the high concentration of first-generation immigrant families in the inner city of Chicago during the early twentieth century, many prominent early studies in urban sociology focused around the effects of carrying culture roles and norms into new and developing environments. Political participation and the rise in inter-community organizations were also highly followed in this period, with many metropolitan areas adopting census techniques that allowed for information to be stored and easily accessible by participating institutions such as the University of Chicago. Sociologists Park, Burgess and McKenzie, professors at the University of Chicago and three of the earliest proponents of urban sociology, developed subcultural theories, which helped to explain the role of local institutions in the formation of ties. Subcultural theories popularized the idea that segments of society, such as gangs and homeless populations, had internal systems of value and order. This theory was in contrast to the prevailing belief that urbanization produced only social disorganization and alienation.
Urban Ecology
Urban ecology refers to an idea that emerged out of the Chicago School that likens urban organization to biological organisms. Urban ecology has remained an influential theory in both urban sociology and urban anthropology over time. The theory is essentially an extended metaphor that helps to explain how conflicting subgroups exist in shared urban spaces and systems. Like biological systems, urban subgroups are dependent on one another for healthy functioning and are also dynamic—that is, they flourish and decline based on political, economic, and social tides. Relating this to functionalist theory, one can look at immigration and emigration trends. As people enter and leave a country, they are dependent upon one another, as well as the new culture, to assimilate and enter into a new society. Immigrants become emigrants and vice-versa; in this way, the chain of life continues in terms of societal relations.
17.4.2: Social Interaction in Urban Areas
Social scientists have focused on social interactions in urban areas because cities bring together many cultural strands.
Learning Objective
Design a research question using one of the four central approaches to the anthropological study of cities
Key Points
- Urban areas impact individuals’ relationships with one another. Economic problems and power dynamics are intensified in small spatial areas in which resources are scarce due to dense populations.
- Social scientists seek to understand how metropolitan social dynamics are distinct from those in other contexts.
- German sociologist Georg Simmel was a founding father of this sociological subfield. He gave a speech that analyzed the effects of urbanity on the mind of the individual, arguing that urban life irreversibly transforms one’s mind.
- Social scientists ask two sets of questions about social life in urban areas. The first set asks how social interactions are shaped by urban environments, and the other asks more pointed questions about how the architecture and physical space of a city influence social interactions.
Key Terms
- urban ecology model
-
In the urban ecology model, the social scientist considers how individuals interact with others in their urban community.
- sociology of architecture
-
Sociology of architecture is a term that describes the sociological study of either the built environment or the role and occupation of architects in modern societies.
- sociology of space
-
The sociology of space is a sub-discipline of sociology that is concerned with the spatiality of society. It examines the constitution of spaces through action, as well as the dependence of action on spatial structures.
Examples
- Urban social structure differs in significant ways from rural life, which in turn affects the form of social interactions. For example, on a daily basis an urban dweller is likely to come into contact with numerous strangers, if only in passing. By contrast, rural dwellers may come into contact with only people who look familiar. Contact with the hypothetical person that Georg Simmel calls “the stranger” changes the way urban dwellers think about intimacy, personal space, and casual interactions. To be concrete, an urban dweller may be suspicious of passersby, while a rural dweller may greet them.

Around half of the world’s population currently lives in an urban area, and the United Nations World Urbanization Prospects Report suggests that 60% of the world’s population will live in an urban area by the year 2030. As such, social scientists have paid increasing attention to the particular types of social dynamics that develop in urban environments.
Social scientists have focused on social interactions in urban areas because cities have the unique capacity to bring together many cultural strands. Economic problems and power dynamics are intensified in small spatial areas in which resources are scarce due to dense populations. Further, cities operate as zones of confluence for economic relationships and other types of diversity as new ideas, people, and goods are constantly flowing through urban areas. As a result, the people there have to respond to new influences, often bringing dominant strains of culture to the fore. What does a particular group of people value? What can they tolerate? What do they revolt against? All of these questions play out in cities.
Urban anthropology is an anthropological subfield primarily concerned with urbanization, poverty, and the consequences of neoliberalism, or the contemporary political movement that advocates economic liberalization, free trade, free movement, and open markets. There are four central approaches to an anthropological study of cities. The first is an urban ecology model in which the social scientist considers how individuals interact with others in their urban community. Second, one could focus on power and knowledge, specifically how these elements are combined in the development of urban structures. Third, one can study how localities relate to communities beyond their bounds, such as an analysis of the relationship between the local and the global. Finally, one can consider how political economy, or the study of production, law, and distribution, is essential to a city’s infrastructure and the consequences of this interdependence. These questions have been closely examined in urban contexts in the past fifty years.
Despite the relatively recent ascent of urban sociology, sociologists have long studied the sociological implications of space. Georg Simmel, a German sociologist from the turn of the twentieth century, famously considered the social impact of urban environments in The Metropolis and Mental Life. Published in 1903, this work was originally given as one of a series of lectures on all aspects of city life by experts in various fields, ranging from science to religion to art. Simmel was originally asked to lecture on the role of intellectual life in Berlin, but he effectively reversed the topic in order to analyze the effects of urbanity on the mind of the individual. Simmel argues that urban life irreversibly transforms one’s mind. Simmel does not say that these changes are negative, but writes that structural forces on socialization are particularly strong in an urban milieu.
Social scientists thus ask two sets of questions about social life in urban areas. The first set asks how social interactions are shaped by urban environments and how social interactions in urban environments are distinct from social interactions in other contexts. These are the types of questions asked by Simmel and urban anthropologists. The other strand of analysis asks more pointed questions about how the architecture and physical space of a city influence social interactions. This second set of questions is taken up by urban planners, architects, and, in the social sciences, by individuals who study the sociology of architecture and the sociology of space. Clearly, questions about social interactions in urban areas cluster loosely and are quite broad. However, it is clear that social dynamics are influenced by urbanity and sociologists intentionally study this field in broad terms to understand the multifaceted ways in which urban life influences society.
Urban Social Life
In cities, such as Beijing, people are exposed to large populations of unfamiliar faces, including transient visitors. This changes one’s orientation to the urban community.
17.4.3: Urban Neighborhoods
Neighborhoods are small units of social organization within a larger social area, such as a city or town.
Learning Objective
Name three classic qualities of a neighborhood
Key Points
- Neighborhoods have historically existed in every large urban area.
- Neighborhood action tends to quickly produce visible results, particularly when compared to larger social units. Because neighborhood action involves interaction with others, such actions create stronger social ties among those inhabiting the area.
- Neighbors socialize one another through significant numbers of face-to-face interactions.
- The tendency of members of a neighborhood to share voting patterns and other views is called the neighborhood effect.
- In Canada and the United States, neighborhoods are often given official or semi-official status through neighborhood associations, neighborhood watches, or block watches.
Key Terms
- Social ties
-
Because neighborhood action involves others, such actions create stronger social ties amongst those inhabiting the area.
- neighborhood effect
-
Individuals in neighborhoods tend to vote similarly.
- neighborhood
-
A division of a municipality or region, formally or informally divided
Example
- Greenwich Village is an example of a famous neighborhood in New York City known broadly for countercultural and artistic activities. People likely move to Greenwich Village because they hold values that are in line with its reputation, but once they move there socialization among neighbors likely increasing the strength and specificity of their shared views through the neighborhood effect. One might move to Greenwich Village due to an in social justice and then develop a particular interest in economic fair trade, for example.
A neighborhood is a geographically localized community within a larger city, town, or suburb. Neighborhoods are often social communities with considerable face-to-face interactions among members. While neighborhoods have expanded with industrialization and the development of even larger urban areas, neighborhoods have always existed. Archaeologists have demonstrated through excavations that pre-industrial urban areas contained neighborhoods. As is true in the present day, neighborhoods were historically generated by social interaction among people living near one another. They are extremely localized social units only a step above a household and not directly under government control. In this sense, neighborhoods are usually informal, rather than pre-planned by government agencies. In some pre-industrial urban traditions, basic municipal functions, such as protection, social regulation of births and marriages, cleaning, and upkeep were handled informally by neighborhoods rather than by urban governments. As is still commonly the case, neighborhoods in pre-industrial cities often had some degree of social specialization or differentiation. Ethnic neighborhoods were important in past cities and remain common in cities today.
Sociologists are interested in neighborhoods as small, localized social, economic, and political units. Neighborhoods are close to universal, as most people in urbanized areas would consider themselves to be living in one. Neighborhood action tends to quickly produce visible results, particularly when compared to larger social units. Because neighborhood action involves frequent interaction with others, such actions create stronger social ties among those inhabiting the area.
In Canada and the United States, neighborhoods are often given official or semi-official status through neighborhood associations, neighborhood watches, or block watches. These may regulate such domestic matters as lawn care and fence height and provide other social services such as block parties, neighborhood parks, and community security.
Though neighborhoods are less strictly regulated by government officials, this is not to say that neighborhoods lack political power. Indeed, sociologists and political scientists have found that individuals in neighborhoods tend to vote similarly in what is referred to as the neighborhood effect. The voting preference of a neighborhood tends to be formed by consensus, where people tend to vote with the general trend the neighborhood. Of course, this is not to imply pure causation, but rather tha individuals with similar voting preferences choose to live in the same area. Socialization within neighborhoods is quite significant, particularly when this form of socialization involves significant face-to-face interactions with one’s neighbors.
Neighborhood Watch
Neighborhood watches are one form of semi-formal neighborhood associations that contribute to the regulation of crime in an area that is not an independent political unit. Neighborhood watch associations function under citywide police and have no legal authority as crime enforcement officers.
17.4.4: Urban Decline
Urban decline is the process whereby a previously functioning city or neighborhood falls into disrepair.
Learning Objective
Analyze the causes and solutions to urban decline experienced both during the Industrial Revolution and in America today
Key Points
- It is often caused by a decline in the economic opportunities available in a particular city.
- The issues associated with the modern iteration of urban decline began during the Industrial Revolution, when many people moved to cities looking for industrial work, and then fell into poverty with economic changes and deindustrialization.
- Deindustrialization is the process of social and economic change caused by the removal or reduction of industrial capacity in a region that is known for its manufacturing industry.
- New Urbanism seeks to combat the economic and architectural problems associated with urban decline.
- In the United States, early government policies included “urban renewal” and the construction of large-scale housing projects for the poor.
Key Terms
- white flight
-
The large-scale migration of whites of various European ancestries, from racially mixed urban regions to more racially homogeneous suburban areas.
- deindustrialization
-
The loss or deprivation of industrial capacity or strength.
- blight
-
Anything that impedes growth or development, or spoils any other aspect of life.
Example
- San Antonio, Texas is an example of a U.S. city that formally adopted the precepts of New Urbanism in an attempt to eradicate urban decline. After facing economic hardship and seeing the decline of local infrastructure and resources, San Antonia created official districts with self-governing neighborhood associations, and redeveloped urban space to create neighborhood centers.
Urban decline is the process whereby a previously functioning city or neighborhood falls into disrepair and decrepitude. Features of urban decline include deindustrialization, depopulation, economic restructuring, abandoned buildings, high unemployment, fragmented families, political disenfranchisement, crime, and a desolate landscape. Since the 1970s and 1980s, urban decline has been associated with Western cities having experienced institutional restructuring. In many countries outside of the West, urban decline manifests as peripheral slums at the outskirts of cities. In contrast, in North American and British cities, the impoverished areas begin to develop in the city center as individuals relocate their residences to suburban areas outside of the city. This process is frequently called white flight, in reference to the fact that the central urban areas usually remain inhabited by minority populations when white populations leave. Another characteristic of urban decay is blight, the visual, psychological, and physical effects of living daily life among empty lots, abandoned buildings, and condemned houses. Such desolate properties are socially dangerous to the community because they attract criminals and gangs, increasing the volume of crime.
Causes
But what causes urban decay? Though scholars can identify factors that contribute to urban decline, it is notoriously difficult to explain precisely why one urban area slips into decline and another with similar circumstances does not. That being said, urban decline results from some combination of socioeconomic decisions, such as the city’s urban planning decisions, the poverty of the local populace, the construction of urban infrastructure (such as freeways, roads, and other elements of transportation), and the depopulation of peripheral lands by suburbanization.
Historic Causes
In some ways, urban decline is an inevitable result of urbanity itself. Cities tend to grow because of momentary economic booms. These economic successes can either evolve and sustain themselves, or contract. Economic decline tends to lead to urban decline. Given that economic fluctuations have such profound effects on urban development, it makes sense that issues associated with the modern iteration of urban decline began during the Industrial Revolution, the time period in the late eighteenth and early nineteenth century when rural people flocked to cities for employment in manufacturing. Overpopulation in very small spatial areas became a serious issue. While the individuals who worked in manufacturing positions frequently worked and lived in extremely poor conditions, the owners of the mills became rich quickly, bringing a striking influx of economic growth suddenly to cities. However, subsequent economic changes left many newly-grown cities economically vulnerable and marred with employment factors that contribute to urban decline.
Changes in means of transport, from public to private—or specifically from public trains to private motor cars—eliminated some advantages of living and working in the city and enabled suburbanization. Following World War II, political decisions in the U.S. further solidified the already growing trend of suburbanization. Many cities used city taxes to build new infrastructure in remote, racially-restricted suburban towns. Historically in the U.S., the white middle class gradually left the cities for suburban areas because of the perceived higher crime rates and dangers caused by African-American migration to northern cities after World War I; this demonstrates so-called white flight. This trend became more permanent with the construction of the Interstate Highway System under President Dwight D. Eisenhower in the 1960s.
Recent Causes
Deindustrialization, or the process of social and economic change caused by the removal or reduction of industrial capacity in a region that is known for its manufacturing industry, is one of the main recent causes for urban decline in the United States. Deindustrialization is a main culprit in creating the economic conditions that contribute to urban decline by pushing jobs outside of the main urban area. An example of deindustrialization and urban decline in the United States is Detroit. After free-trade agreements were instituted with less developed nations in the 1980s and 1990s, Detroit-based auto manufacturers relocated their production facilities to other areas where wages and working standards (and therefore costs of operation) were lower. Detroit and other industrial towns, such as Cleveland, Pittsburgh, and St. Louis, were once centers of production and associated with high standards of living. Today, they are associated with a high concentration of poverty, unemployment, abandoned buildings and noticeable isolation.
Response
The current response to urban decay has been positive public policy and urban design using the principles of New Urbanism. New Urbanism is an urban design movement that promotes walkable neighborhoods that contain a range of housing and professional options. The movement came about in the U.S. in the 1980s and continues to have impact on urban planning .
Pruitt-Igoe Housing Development Decay
The Pruitt-Igoe housing projects in St. Louis were built under a policy of urban renewal intended to provide affordable housing, but soon turned into a site of urban blight. They have since been demolished and the land is being redeveloped under a policy of New Urbanism.
17.4.5: Homelessness
Homelessness is a social problem, caused by structural inequalities and lack of resources, where certain individuals are at higher risk.
Learning Objective
Explain the various social factors that contribute to homelessness, including categories of high risk people
Key Points
- Those at a higher risk of becoming homeless include veterans, people suffering from substance abuse or mental disorders, and the unemployed.
- Homelessness is a problem intimately associated with urban areas and the resource limitations that exist because of a populous urban environment.
- Social factors also contribute to homelessness, especially economic downturns, deinstitutionalization, and lack of family support.
- As with veterans, many individuals with substance abuse problems and mental disorders have difficulty finding work.
Key Terms
- homelessness
-
The condition of a person or persons living without a regular dwelling. People who are homeless are most often unable to acquire and maintain regular, safe, and adequate housing.
- Medicaid
-
U.S. government system for providing medical assistance to persons unable to afford medical treatments.
- deinstitutionalization
-
The process of abolishing a practice that has been considered a norm.
Example
- After the economic crash of 2008, many families were no longer able to make payments on their mortgages and were evicted from their homes. Oftentimes, these families either stayed for short periods with extended family or lived in their vehicles. While these families do not adhere to the stereotypical images of a homeless person who sleeps on the street, they are homeless under the law and according to most colloquial understandings of the term.
Homeless people are those who lack a regular, adequate residence. Although homeless people stereotypically live on the streets, many may spend some nights in shelters, transitional housing, or cars and makeshift dwellings.
Homelessness is a social problem, due in large part to structural inequality and the maldistribution of resources. However, individual risk factors help explain why certain individuals become homeless instead of others . Those at a higher risk of becoming homeless include veterans, people suffering from substance abuse or mental disorders, and the unemployed.
Risk Factors
Many veterans return from war with insufficient training to successfully navigate the job market or with skills that are not in demand in the civilian world. They may also suffer from chronic physical or psychological conditions sustained in combat that make regular employment difficult. The federal government provides services to help veterans transition to civilian life, but some still struggle and, unable to find a job or to reintegrate, end up homeless.
Individuals with substance abuse problems and mental disorders represent a large number of the homeless. In the United States, 22 percent of the homeless have serious mental illnesses or are physically disabled, and 30 percent have substance abuse problems. Popular perception often blames the victim, suggesting these individuals are at fault for becoming homeless. However, this perspective denies structural elements that contribute to both homelessness and substance abuse.
Although most homeless people are single men, in tough economic times, families are at increased risk of homelessness due to unemployment. When unemployment rates increase, homelessness tends to increase, too. When markets crash, even families that appeared to be middle class may suddenly become homeless. In the United States, 23 percent of homeless people are families with children—the fastest growing segment of the homeless, due largely to the economic collapse in 2008.
Social Causes
Economic downturns are one of many social factors that cause homelessness. Urbanization itself may contribute to the problem. Cities must sustain a large population in a small area, which puts pressure on resources . In the United States, 71 percent of the homeless reside in urban areas.
Street Dwellers in Mumbai
On the outskirts of large developing cities, it may be a fine line between living in a slum or as a homeless person, as neither group generally possesses legal rights to land or a permanent dwelling.
Homeless people who suffer from substance abuse or mental illness often lack access to effective treatment options, a condition exacerbated by deinstitutionalization in the 1960s and 1970s. Prior to the 1960s, individuals with mental illness were frequently committed to long-term institutions, but deinstitutionalization closed these institutions in favor of community-based treatment. Unfortunately, many people released from these institutions had no place to go and wound up homeless.
Family support can provide a buffer against homelessness; those who lack support are at increased risk. Over half of children who “age out” of social systems such as foster care find themselves homeless. Social stigma also contributes to homelessness. Teenagers who become homeless have often run away from home or been thrown out by their parents, frequently because of their sexual orientation. A 2010 study by the Center for American Progress revealed that 20 to 40 percent of homeless youth identify as LGBT.
Solutions
Given its diverse and deeply entrenched causes, homelessness is hard to address. In the past, some purported solutions have been more attentive to the desires of privileged members of society than to the homeless; they have reinforced stigma and criminalized vagrancy in an attempt to sweep the problem under the rug. Rather than stigmatizing or criminalizing homeless individuals, a long-term approach to combat homelessness must focus on meeting the needs of the homeless. The most promising solutions are holistic approaches that combine housing, health care, and education, but such programs are limited. Instead, a policy patchwork provides some housing, some healthcare, and some education, but not a comprehensive plan.
Nonprofit and government programs exist to provide affordable housing, but face funding problems and a history of failure. In the mid-twentieth century, the government attempted to solve the housing crisis by creating massive housing projects with low rents to support the needs of low-income families, but facilities were decrepit, had little security, and eventually became havens for crime—perpetuating, rather than solving, many of the problems faced by low-income individuals. Many of these projects have been destroyed and government housing authorities have focused more on creating mixed-income affordable housing.
Given the large percentage of homeless who suffer from illness, adequate health care is an essential component to ensuring that people stay off of the streets. But in the United States, most people get health insurance through employers, leaving the unemployed with inadequate access to healthcare. Medicaid was established to provide healthcare to the indigent, but Medicaid lacks funding to adequately meet homeless needs.
Education can provide homeless children a way out, but practical barriers, such as residency restrictions, medical record verification, and transportation issues, often keep homeless youth out of school. The McKinney-Vento Act attempts to overcome these barriers by mandating equal opportunity for a free public education for homeless students.
Homeless Seek Shelter
People who are homeless are often forced to sleep under makeshift shelters that offer little protection from the elements and no security.
17.4.6: Alienation
Alienation refers to the distancing of people from each other, from what is important and meaningful to them, or from themselves.
Learning Objective
Compare the theories of economic and social alienation posited by Marx, Simmel, Tönnies, and Durkheim
Key Points
- Alienation has been primarily described in two ways: economic alienation, as articulated by Karl Max, or social alienation, as described by Émile Durkheim with his concept of anomie.
- Both economic and social alienation come to bear in urban environments as cities exacerbate the economic pressures associated with capitalism and create environments in which it is more difficult to attach oneself to a social structure.
- Social alienation was famously described by French sociologist Émile Durkheim in the late nineteenth century with his concept of anomie.
- Anomie describes a lack of social norms, or the breakdown of social bonds between an individual and his community ties, resulting in the fragmentation of social identity.
Key Terms
- alienation
-
Emotional isolation or dissociation.
- capitalism
-
A socio-economic system based on private property rights, including the private ownership of resources or capital, with economic decisions made largely through the operation of a market unregulated by the state.
- anomie
-
Alienation or social instability caused by erosion of standards and values.
Example
- A person who lives in a densely populated Manhattan high-rise apartment building but does not know anyone in the building might experience anomie, or a feeling of detachment and alienation from their social surroundings.
Alienation refers to the estrangement, division, or distancing of people from each other, from what is important and meaningful to them, or from their own sense of self. The term “alienation” has a long and storied history within sociology, most famously with Karl Marx’s use of the phrase in the mid-nineteenth century to describe the distancing of a worker from the product of his labors. This article seeks to trace “alienation” through sociological theory by discussing Marx’s use of the term, applying it to social contexts with Emile Durkheim’s notion of anomie, and finally discussing alienation in a modern context using technological examples.
Karl Marx
Marx most clearly articulates his meaning of alienation in Economic and Philosophic Manuscripts (1844) and The German Ideology (1846). Here, Marx contends that alienation is endemic in any system based on capitalism. Marx argues that in emerging systems of capitalist industrial production, workers inevitably lose control of their lives and their selves by not having any control of their work. As a result, workers never become autonomous, self-realized human beings in any significant sense, except in the ways in which the bourgeoisie wants the worker to be realized. Marx refers to this as being alienated from one’s work, and as such one’s self.
Marx’s criticisms were directed at capitalist structures, not urban areas specifically. However, one cannot completely divorce urbanity and capitalism. Of course, urban areas do not come from capitalism; there have been urban areas throughout history, emerging from many different economic systems. However, capitalist economies do tend to encourage individuals to congregate in urban areas when seeking out industrialized work. Countries’ populations tend to trend more urban the more capitalist the country’s economy. Limitations on resources are exacerbated when there is a large population in a particular area. When there is more stress on limited available resources, one pays more attention to how those resources are distributed, such as by the free market means of capitalism. As such, the issues that arise with the unequal distribution of resources under capitalism’s tenets are exacerbated in urban areas. Further, scholars following Marx more directly applied his theories to urban spaces.
Georg Simmel and Ferdinand Tönnies
Late-eighteenth-century German sociologist Georg Simmel, considered to be one of the founders of urban sociology, wrote The Philosophy of Money, describing how relationships are increasingly mediated by money. Simmel’s colleague, Ferdinand Tönnies, authored Gemeinschaft and Gesellschaft (Community and Society) about the loss of primary relationships, such as familial bonds, in favor of goal-oriented, secondary relationships in capitalist, urban environments.
Tönnies’s work shifted from conceiving of alienation in economic terms to thinking of alienation in social terms. Of course, this transition is not so simple; Marx’s work on economic alienation was fundamentally social in nature. However, many of Marx’s predecessors focused on the social consequences of alienation where Marx emphasized the economic causes for alienation. Thus, the reorientation to social alienation did not represent a break in thinking on alienation, just a shift to new directions.
Émile Durkheim
Social alienation was famously described by French sociologist Émile Durkheim in the late nineteenth century with his concept of anomie. Anomie describes a lack of social norms, or the breakdown of social bonds between an individual and his community ties, resulting in the fragmentation of social identity. According to Durkheim, when one is caught in a normless state in society, one has no parameters to hold on to and, accordingly, cannot situate oneself within that society, and so becomes socially adrift and isolated. Durkeim writes that anomie is common when the surrounding society has undergone significant changes in its economic fortunes, whether for better or for worse, and more generally, when there is a significant discrepancy between the ideological theories and values commonly professed, and what is actually practicable in everyday life. Durkheim was writing at a time of sudden industrialization and mass movement of families from rural areas into urban areas. The sociocultural changes associated with such a move contributed to individuals feeling uncomfortable with their new environments, and feeling as though they could not easily place themselves in a social order .
Urban Anomie
A resident in a high-rise apartment building that may house hundreds or thousands of people may feel social alienation if they do not engage in face-to-face interactions with neighbors, who remain strangers despite close physical proximity.
The general principles outlined by Durkheim in his descriptions of anomie can be seen in any social context, including our own. Current debates about social alienation and anomie pop up in many social critiques of an increasingly technological world. Many popular critics and scholars have wondered if the development of a more robustly technological sociality, through mechanisms such as Facebook and multiplayer online gaming sites, can approximate the same positive consequences of more traditional, face-to-face socialization.
Labor and Alienation
An employee on a car assembly line might feel alienation from the product of his/her labor, as he/she cannot claim credit for the finished product (the car), and perhaps cannot even afford to own the car the assembly line produces.
17.4.7: Community
The term community refers to a group of interacting people, living in some proximity, either in space, time, or relationship.
Learning Objective
Diagram examples of geimeinschaft, gesellschaft, mechanical solidarity, and organic solidarity within your own community or communities, keeping in mind that these concepts cannot always be neatly separated
Key Points
- Members of communities share either proximity or interests.
- In the late nineteenth century, sociologist Ferdinand Tönnies theorized types of social groups by dividing human associations into gemeinschaft (communities) and gesellschaft (societies).
- Geimeinschaft are characterized by community members having shared views of society and close social ties. Gesellschaft are characterized by members having personal interest in being a member of society.
- Sociologist Émile Durkheim theorized community by understanding social solidarity in terms of mechanical solidarity and organic solidarity.
- Mechanical solidarity is the sense of community that comes about when members are relatively homogeneous.
- Organic solidarity comes about when individuals are mutually dependent upon one another.
Key Terms
- Gemeinschaft und Gesellschaft
-
Gemeinschaft und Gesellschaft are sociological categories introduced by the German sociologist Ferdinand Tönnies for two normal types of human association.
- mechanical solidarity
-
It normally operates in “traditional” and small scale societies. In simpler societies (e.g., tribal), solidarity is usually based on kinship ties of familial networks.
- organic solidarity
-
It is social cohesion based upon the dependence individuals have on each other in more advanced societies.
Examples
- The bond between two people who are both lawyers is an example of gemeinschaft, or mechanical solidarity; the two share a community because they have their occupation in common. The bond between a lawyer and a criminal is an example of gesellschaft or organic solidarity; the two exist in the same society in a relationship based on interdependence, as the criminal provides income to the lawyer and the lawyer provides legal services to the criminal.
- The bond between a lawyer and a criminal is an example of gesellschaft or organic solidarity — the two exist in the same society in a relationship based on interdependence, as the criminal provides income to the lawyer and the lawyer provides legal services to the criminal.
The term community refers to a group of interacting people, living in some proximity, either in space, time, or relationship. A community is typically a social unit that is larger than a single household, comprised of individuals that share values and thus create an environment of social cohesion. Members of a community have things in common, be it a shared geographic location or a shared interest. Increasingly, the notion of community is becoming unhinged from geographic location as individuals form more and more developed webs of society online around shared interests and pursuits.
Gemeinschaft and Gesellschaft
German sociologist Ferdinand Tönnies distinguished between two types of human association: gemeinschaft, or community; and gesellschaft, or society. In his 1887 book, aptly titled Gemeinschaft und Gesellschaft, Tönnies argued that gemeinschaft is perceived to be a tighter and more cohesive social entity, due to the presence of a “unity of will.” He added that family and kinship ties were the perfect expressions of gemeinschaft, but that other shared characteristics, such as living in the same place or believing the same things, could also result in the same sense of community that is the fundamental element of gemeinschaft. Gemeinschaften are broadly characterized by a moderate division of labor, strong personal relationships, strong families, and relatively simple social institutions. Governance does not need to be strong to enforce social norms due to a collective sense of loyalty that individuals feel for community, and an internal alignment and identification with the social norms.
Gesellschaft, on the other hand, is a group in which group members are motivated to take part in the group purely for reasons of self-interest. While individuals may come to identify with their societies, the larger association never takes precedence over the individual’s self interest and, as such, these associations lack the same level of shared norms as gemeinschaft. Unlike gemeinschaften, gesellshcaften emphasize secondary relationships rather than familial ties, resulting in an individual feeling less of a bond and less loyalty to society at large. Social cohesion in gesellschaften typically derives more from an elaborate division of labor. Ultimately, Tönnies viewed gemeinschaft and gesellschaft as pure, sociological categories that are not represented in real life. In reality, all associations are a mix of gemeinschaft and gesellschaft.
Mechanical and Organic Solidarity
In 1893, French sociologist Émile Durkheim incorporated the ideas of gemeinschaft and gesellschaft, particularly their influences on their respective divisions of labor, into his theory of social solidarity, published as The Division of Labor in Society. In this work, Durkheim establishes two types of social communities that correlate with types of society. Mechanical solidarity is a type of community in which social cohesion comes from the homogeneity of individuals. People feel connected, as though they are a part of a community, because they are similar. Mechanical solidarity speaks to the moderate division of labor and close resemblance in social norms exhibited by Tönnies’s gemeinschaft.
Durkheim distinguished mechanical solidarity from organic solidarity, or a sense of community developed by the sense of interdependence that arises from specialization of work and complementary skills and interests between people. This mirrors Tönnies’s gesellchaft. Industrialized societies build their senses of community by making people dependent upon one another due to highly specialized divisions of labor. For example, operating under a form of mechanical solidarity, Tina feels like she and Amy belong to the same community because they are both hunters. Under the parameters of organic solidarity, Tina and Amy feel like they belong to the same community because they perform different tasks and help one another. Tina hunts and Amy does not know how, but Amy knows how to build a house and Tina does not. Tina and Amy help each other, each providing a needed service for the other, and thus create a sense of social solidarity—a sense of community.
17.4.8: Noninvolvement and the Diffusion of Responsibility
Diffusion of responsibility is a phenomenon in which a person is less likely to take responsibility for an action when others are present.
Learning Objective
Give examples of the bystander effect, diffusion of responsibility, and anomie in contemporary society
Key Points
- The bystander effect refers to cases where individuals do not offer any means of help to a victim in an emergency situation when they believe that others are present and will assist.
- Alternatively, diffusion of responsibility can also encompass a person’s refusal to take personal responsibility for their own actions, such as the “only following orders” defense used in the Nuremberg Trials.
- Refusal to assume personal responsibility for one’s actions or inaction can result in one feeling alienated from society and feeling useless. These are characteristics of Durkheimian anomie.
- Refusal to assume personal responsibility for one’s actions or inaction can result in one feeling alienated from society and feeling useless, characteristics of Durkheimian anomie.
Key Terms
- anomie
-
Alienation or social instability caused by erosion of standards and values.
- diffusion of responsibility
-
Diffusion of responsibility is a socio-psychological phenomenon whereby a person is less likely to take responsibility for an action (or for inaction) when others are present.
- bystander effect
-
When someone is less likely to help another if other potential helpers are present.
Examples
- Psychological experiments have demonstrated that individuals are unlikely to consider a situation abnormal if there are sufficient bystanders who act as though the situation is conventional. Participants were placed in a classroom with two actors who sat silently by as smoke began to fill the room. In many cases, the participant did not comment on the apparent smoke for long after they took note of it.

Diffusion of responsibility is a socio-psychological phenomenon whereby a person is less likely to take responsibility for an action (or for inaction) when others are present. In such situations, individuals assume that others have already taken responsibility and therefore they have no moral obligation to do so. Alternatively, individuals might feel as though no one can find them responsible because there is no way to single out their behaviors from the rest of the group. Because they will not be forced to take responsibility, they choose not to do so on their own accord. Diffusion of responsibility tends to occur in groups of people above a critical size and when responsibility is not explicitly assigned. It rarely occurs when the person is alone and diffusion increases in groups of three or more.
Bystander Effect
The bystander effect is another phenomenon that is closely related to diffusion of responsibility. It refers to cases where individuals do not offer any means of help to a victim in an emergency situation when they believe that others are present. The probability of helping victims is inversely related to the number of bystanders; the greater the number of bystanders, the less likely it is that any one of them will help. The mere presence of bystanders greatly decreases intervention because as the number of bystanders increases, any given bystander is less likely to interpret the incident as a problem and less likely to assume responsibility for taking action.
Nuremberg Defense
Diffusion of responsibility also includes positive behaviors, or the commission of actions, when an individual feels that he can pin the consequences of those behaviors on others rather than assume personal responsibility for them. This type of positive diffusion of responsibility constitutes the basis of the Nazi defense in the international Nuremberg Trials. The Nuremberg Trials were a series of military tribunals held by the victorious Allied forces following World War II in which many Nazi leaders were prosecuted for war crimes. The main Nuremberg Trial charged 24 Nazi leaders with participation in a conspiracy for a crime against the peace, planning, initiating, and waging wars of aggression and other crimes against the peace, war crimes, and crimes against humanity. Significantly, while all of the 24 charged were all high up in Nazi leadership, they were not the main Nazi war architects, such as Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, since all three of these men had committed suicide before the trials began. As such, the 24 men charged were all in serious leadership positions, but also received orders from higher-ups. This fact—that the defendants had received orders—became the heart of their defense, as they argued that they were not responsible for the charges because they were “only following orders. “
Urban Contexts
Some have argued that the problems associated with the diffusion of responsibility, particularly the form that manifests as inaction, multiply in urban contexts. When there are more people around, the more likely you are to assume that someone else will do something about the problem rather than fix it yourself. This sense of a lack of individual impact in populous places contributes to the overrepresentation of anomie in urban areas. Anomie was a concept developed by French sociologist Émile Durkheim in his 1897 study Suicide, describing a lack of social norms, or the breakdown of social bonds between an individual and his community ties, resulting in the fragmentation of social identity. According to Durkheim, when one is caught in a normless state in society, one has no parameters to hold on to and, accordingly, cannot situate oneself within that society and becomes socially adrift and isolated. Durkheim writes that anomie is common when the surrounding society has undergone significant changes in its economic fortunes, whether for better or for worse, and more generally, when there is a significant discrepancy between the ideological theories and values commonly professed and what is actually practicable in everyday life. When one feels that he need not take personal responsibility for his actions (or inaction, as it may be) but can instead rely upon the actions of others, one may feel unconnected to society. In this sense, diffusion of responsibility may mean that one feels insignificant and unconnected.
Rio de Janeiro Mugging
Studies have shown that bystanders who observe street crime are unlikely to intervene, often under the belief that others will take responsibility for intervening in the situation.
17.5: Urban Problems and Policy
17.5.1: Suburbanization
Suburbanization is a term used to describe the growth of areas on the fringes of major cities.
Learning Objective
Analyze the various push and pull factors that lead to suburbanization, including the concept of white flight, as well as the impact of suburbanization on urban areas
Key Points
- In the mid-twentieth century United States, suburbanization was caused by federal governmental incentives to encourage suburban growth and a phenomenon dubbed “white flight” where white residents sought to distance themselves from racial minorities in urban areas.
- Push factors are those that push people out of urban areas while pull factors are those that entice individuals to leave urban zones for the suburbs.
- Pull factors are those that attract people to suburbs in particular (like more land or bigger homes).
- White flight refers to the large-scale migration of whites from racially mixed urban regions to more racially homogenous suburban areas.
Key Terms
- white flight
-
The large-scale migration of whites of various European ancestries, from racially mixed urban regions to more racially homogeneous suburban areas.
- Interstate Highway System
-
The Dwight D. Eisenhower National System of Interstate and Defense Highways (commonly known as the Interstate Highway System, Interstate Freeway System or the Interstate) is a network of limited-access roads, including freeways, highways, and expressways, forming part of the National Highway System of the United States.
- Redlining
-
Redlining is the practice of increasing the cost of services such as banking and insurance or denying access to jobs, health care, or even supermarkets to residents in particular areas.
Examples
- St. Louis is an example of a city that fell into urban decline largely as the result of white flight that led to widespread suburbanization. While white flight was concentrated in the post-WWII era, the effects are still present today. The population within St. Louis city limits has a much greater proportion of racial minorities than the suburbs surrounding the city does, and primary business districts have developed in the suburbs rather than in the original city center.
- The traditional suburban cul-de-sac residential design is one pull towards suburban living for many families. Cul-de-sacs are intended to prevent fast-moving traffic and strangers from entering residential neighborhoods, and are thus taken to indicate that suburbs are a safe place for children.
Suburbanization is a term used to describe the growth of areas on the fringes of major cities. Sudden and extreme relocation out of urban areas into the suburbs is one of the many causes of urban sprawl, as suburbs grow to accommodate the increasingly large population. Many residents of suburbs still work within the central urban area, choosing instead to live in the suburbs and commute to work.
Suburbanization is caused by many factors that are typically classified into push and pull factors. Push factors are those that push people out of their original homes in urban areas into suburban areas. Pull factors are those that attract people to suburbs in particular. The main push factors in encouraging suburbanization have to do with individuals feeling tired of city life and the perception that urban areas are overpopulated, over-polluted, and dirty. Further, the mid-twentieth century movement of “white flight” significantly contributed to the rise of suburbs in the United States. The term refers to the large-scale migration of whites from racially mixed urban regions to more racially homogenous suburban areas. White flight began in earnest in the United States following World War II and continues, though in less overt ways, today.
For many of the families that fled the city in favor of the suburbs, the catalyst was the perception of racially diverse urban areas as lower-class and crime-ridden. Real estate law at the time enabled this process, as many minorities were legally excluded from purchasing properties in suburban areas. These racist practices, called redlining, barred African-Americans from pursuing home ownership, even when they could afford it. Suburban expansion was reserved for middle-class white people, facilitated by increasing wages in the postwar economy and by federally guaranteed mortgages that were only available to whites because of redlining. African-Americans and other minorities were relegated to a state of permanent rentership.
The effects of white flight are still seen today. Take, for example, the case of St. Louis, Missouri. St. Louis is a city surrounded by suburbs that are clumped together as the county of St. Louis. St. Louis County developed as whites fled the city for the suburbs. The racial makeup of the city St. Louis and St. Louis County still reflect the racial component of the county’s origins. According to the 2010 United States Census, the city of St. Louis is 49.2 percent African-American, 43.9 percent Caucasian, 3.5 percent Hispanic, 2.9 percent Asian, and 0.3 percent Native American. By comparison, St. Louis County is 70.3 percent Caucasian, 23.3 percent African American, 3.5 percent Asian, 2.5 percent Hispanic, and 0.03 percent Pacific Islander. At the turn of the century, the racial disparities were even more exaggerated.
Pull factors for suburbanization at the turn of the century included more open spaces, the perception of being closer to nature, and lower suburban house prices and property taxes in comparison to cities. Certain infrastructure changes encouraged families to leave urban areas for suburban ones, primarily the development of the Interstate Highway System and insurance policies favoring suburban areas. Following World War II, President Dwight D. Eisenhower launched an initiative to create federal highways to allow for expansion outside of urban areas. Thus, the interstate highway project of the 1950s was developed with suburbanization in mind. Additionally, the government agreed to underwrite mortgages for suburban one-family homes. In effect, the government was encouraging the transfer of the middle-class population out of the inner city and into the suburbs. This movement is thought to have exacerbated urban decline in cities. Insurance companies also fueled the push out of cities and the growth of suburbs, as it redlined many inner-city neighborhoods. This means that insurance companies would refuse to grant mortgage loans to families seeking housing in urban areas and would instead offer lower rates in suburban areas; combined with the federal loans for single-family suburban homes, one sees a joint enterprise between both public and private entities to encourage suburbanization.
The mass movement of families from urban to suburban areas has had a serious economic impact with changes in infrastructure, industry, real estate development costs, fiscal policies, and more. As a result of the mass residential migration out of urban centers, many industries have followed suit. Companies are increasingly looking to build industrial parks in less populated areas, largely to match the desires of employees to work in more spacious areas closer to their suburban homes. “Making it to the suburbs” has become a modern iteration of the American dream. As residential wealth and corporations continue to leave urban zones in favor of suburban areas, the risk of urban decline increases.
17.5.2: Disinvestment and Deindustrialization
Deindustrialization refers to the process of social and economic change ignited by the removal or reduction of industrial activity.
Learning Objective
Examine the four elements of deindustrialization and its impact on society, in terms of economic restructuring and societal crisis
Key Points
- Deindustrialization is primarily caused by offshoring and shifts toward service sector economies.
- Deindustrialization can have serious socioeconomic consequences in urban areas that used to be reliant on the manufacturing industry for jobs.
- The shift to a service sector economy is called economic restructuring.
- Real industrial production rose in the United States in every year from 1983 to 2007. However, the number of American workers in the manufacturing industry has declined steadily from its peak of 31.5 million in 2000.
Key Terms
- Foreign direct investment
-
Foreign direct investment is investment directly into production in a country by a company located in another country, either by buying a company in the target country or by expanding operations of an existing business in that country.
- balance of trade deficit
-
A situation in which a country imports more manufactured products than it exports.
- economic restructuring
-
Economic restructuring refers to the phenomenon of shifting between two types of economies, such as from a manufacturing to service economy or agricultural to manufacturing economy.
Example
- Detroit, Michigan is an example of a U.S. city that, like other northern manufacturing cities in what is now known as the “rust belt,” has undergone rapid deindustrialization. Detroit was once known for automobile manufacturing and was associated with comfortable, middle-class living. After automobile manufacturing was largely moved overseas, Detroit has come to be known for urban decay and an abandoned city center.
Deindustrialization refers to the process of social and economic change ignited by the removal or reduction of industrial activity/capacity in an area that was formerly supported by the manufacturing industry. Deindustrialization is limited to recent historical moments. It is the inverse process of industrialization—the process of social and economic change that began in the eighteenth century, transforming agrarian societies into industrial ones.
Characteristics of Deindustrialization
Deindustrialization is marked by some combination of four elements.
First, a straightforward decline in the output of manufactured goods or in employment in the manufacturing sector may indicate deindustrialization. However, not every simple decline in output or employment of the manufacturing sector necessarily indicates deindustrialization; short-run downturns may be part of the economic cycle and should not be mistaken for long-term deindustrialization.
Second, deindustrialization may be indicated by a shift from manufacturing to the service sector— economic sectors that focus on serving others rather than producing some physical object. Service sector jobs are seen in government, telecommunication, healthcare, banking, education, legal services, tourism, real estate, or consulting. This shift towards service sector employment would result a shrinking manufacturing sector.
Third, deindustrialization can be marked by a balance of trade deficit, or a situation in which a country imports more manufactured products than it exports.
Finally, deindustrialization can be observed when a nation’s balance of trade deficit is so sustained that the country is unable to pay for the necessary imports of materials needed to further produce goods, initiating a downward spiral of economic decline.
Economic Progress
How is it that economies find themselves in situations of deindustrialization? One explanation centers on economic progress. As economies that were once industrial improve their methods through technological innovation, businesses will find ways to increase productivity or product growth while decreasing the amount of resources they need to devote to production. One “resource” that is particularly expensive is labor. With better technology, employers are able to produce at least the same amount of their product with fewer employees. The decline in employment in manufacturing sectors that comes about from this progress can indicate deindustrialization.
Economic Resturcturing
Another explanation focuses on economic restructuring—institutional and governmental encouragement of the development of a more robust service sector, often at the expense of the manufacturing sector. As the service sector has developed, more and more manufacturing plants have shifted their operations overseas in a process called offshoring. American companies are still involved in the financial aspects of the company; the company remains an American property or American financiers invest through foreign direct investment in companies based abroad. In this model, daily operation occurs overseas, including the hiring of foreign workers in the country where the manufacturing operations are now based. Offshoring demonstrates the importance of scale when considering the process of deindustrialization. While moving a company from the United States to India might result in deindustrialization in America, it does nothing to diminish industry globally. Rather, it redistributes industrialization to India. As such, deindustrialization can be seen as a redistribution of industrial capacity and development rather than a simple decline.
Deindustrialization as a Crisis
When one limits one’s view to a national context, deindustrialization is seen as a crisis. The fact that global industrial capacity has merely been redistributed is little comfort when jobs are being lost at home. According to the Organization for Economic Cooperation and Development (OECD), real industrial production rose in the United States in every year from 1983 to 2007. However, people commonly refer to the United States being in caught in a deindustrialization crisis; growth has slowed and more countries have moved their operations overseas. The number of American workers in the manufacturing industry has declined steadily from its peak of 31.5 million in 2000.
The city of Detroit represents the deindustrialization crisis in the American context. After free-trade agreements were instituted with less-developed nations in the 1980s and 1990s, Detroit-based auto manufacturers relocated their production facilities to other countries with lower wages and work standards. This process took a heavy toll on an auto industry, which was already losing jobs due to technological innovations that required less manual labor. Detroit was once a center of production associated with a high-quality, middle-class standard of living. Today, Detroit is associated with a high concentration of poverty, unemployment, noticeable racial isolation, and a deserted urban center. Deindustrialization can have strongly negative effects in urban areas that were formerly heavily reliant upon the manufacturing sector .
The United States Rust Belt
The Rust Belt refers to northern U.S. cities that have undergone rapid deindustrialization, including the loss of manufacturing jobs. On the map, green areas have seen gains in manufacturing jobs while all other areas have experienced losses.

17.5.3: The Potential of Urban Revitalization
Urban revitalization involves redeveloping blighted urban areas for new uses.
Learning Objective
Examine the postwar development of urban revitalization, specifically related to Title I of the Housing Act of 1949
Key Points
- Urban revitalization has been around since European city planners in the nineteenth century began to consider how to reorganize overpopulated urban areas.
- Title I of the Housing Act of 1949 kick-started the urban renewal program that would reshape American cities.
- Urban renewal can have many positive effects, including better quality housing, reduced sprawl, increased economic competitiveness, improved cultural and social amenities, and improved safety.
- The government has only had mixed success in actually restoring urban areas and has tried to rebrand urban renewal as community redevelopment.
Key Terms
- Housing Act of 1949
-
The American Housing Act of 1949 was a landmark, sweeping expansion of the federal role in mortgage insurance and issuance and the construction of public housing. It was part of Harry Truman’s program of domestic legislation, the Fair Deal.
- eminent domain
-
(US) The right of a government over the lands within its jurisdiction. Usually invoked to compel land owners to sell their property in preparation for a major construction project, such as a freeway.
Example
- The Chicago Housing Authority is transitioning from building high-rise complexes to mid-rise, mixed-income complexes. This shift is part of a large redevelopment plan that seeks to eradicate crime-ridden neighborhoods such as the Cabrini Green Housing Project.
Urban revitalization is hailed by many as a solution to the problems of urban decline by, as the term suggests, revitalizing decaying urban areas. Urban revitalization is closely related to processes of urban renewal, or programs of land redevelopment in areas of moderate- to high-density urban land use. Urban revitalization has been around since European city planners in the nineteenth century began to consider how to reorganize overpopulated urban areas. However, the modern instantiation of urban revitalization is very much a product of the post-World War II economic and social environment. With the influx of money following World War II, the federal government spotlighted American urban areas as the object of renovation.
Most of the postwar development was focused on suburbanization, but urban revitalization was a statutory corollary to suburban development. Title I of the Housing Act of 1949 kick-started the urban renewal program that would reshape American cities. The Act provided federal funding to cities to cover the cost of acquiring declining areas of cities perceived to be slums. According to the act, the federal government paid two-thirds of the cost of acquiring the site, called “the write down,” while the local governments paid for the remaining one-third. Most of the money went towards purchasing the property from the present owners. This process is called “eminent domain,” or the process through which the government acquires private property for the larger public good. The process of eminent domain requires that the government provide due compensation but does not necessarily require the private property owner’s consent. In the post-war era, after acquiring the properties, the government gave much of the land to private developers to construct new urban housing. These federal incentives to revitalize declining urban areas were particularly attractive to cities that were in states of economic decline at the time.
Urban revitalization certainly provides potential for future urban growth, though the story of successes and failures remains mixed so far. Urban renewal can have many positive effects. Replenished housing stock might signify an improvement in quality; urban renewal may increase density and reduce sprawl, and it might have economic benefits that improve the economic competitiveness of the city’s center. It can also improve cultural and social amenities, through the construction of public spaces and community centers, and can improve safety.
Melbourne Docklands Renewal
The Melbourne Docklands were once a vast expanse of unused docks, but they have now been turned into a residential and commercial development.
17.5.4: Urban Gentrification
Gentrification occurs when wealthier people buy or rent property in a low-income or working class neighborhood, displacing residents.
Learning Objective
Discuss the process of gentrification based on three models – demographic, sociocultural and political/economy
Key Points
- While gentrification can bring about higher tax revenues from higher property values, gentrification also dislocates pre-gentrification residents by raising rents beyond their price ranges.
- Gentrification has encountered backlash from the original residents of a community, many of whom organize to fight against the white and wealthy incoming population.
- Several explanations for gentrification exist, including a demographic-ecological model, a sociocultural model, and a political economic model.
Key Terms
- urban pioneers
-
In the 1970s, the first few suburban transplants were called urban pioneers and demonstrated that cities were actually appropriate and viable places to live.
- baby boomer generation
-
The baby boomer generation, or those born during the spike in births in the twenty years following World War II, is starting to reach senior citizenship, and will soon pull from the public funds of Social Security and Medicare.
- gentrification
-
The process of renewal and rebuilding accompanying the influx of middle class or affluent people into deteriorating areas that often displaces earlier usually poorer residents.
Example
- In Gentrification Amid Urban Decline: Strategies for America’s Older Cities, Michael Lang reports on the process and socioeconomic and cultural impact of gentrification in Darien Street in the Bella Vista neighborhood of Philadelphia. A portion of Darien Street is effectively an alleyway because it does not connect to any of the city’s main arteries or thoroughfares and was unpaved for most of its existence. In its early days, this alleyway housed only Italian families. After World War II, the local government launched plans to construct a cross-town highway, so most of the Italian inhabitants of Darien Street moved out; as they moved out, even poorer African-American residents moved in. By the early 1970s, Darien Street houses held very little property value and many homes were abandoned or beyond repair. In 1977, Philadelphia launched a gentrification effort. The first house that was rehabilitated was a corner property that a teacher remodeled and occupied. The next years featured mostly white, middle-class men moving into abandoned houses. Between 1977 and 1979, five of the seven pre-1977 families residing on Darien Street had been pushed out because of increased rents. The remaining two families rented and were expecting to be economically evicted. In five years, from 1977 to 1982, the gentrification of Darien Street replaced the original population, transitioning from seven black households and one white household to two black households and eleven white households. The average rent increased 488%, from $85 to $500 per month. By 1981, a house that had been purchased for $5,000 sold for $35,000. Of the five black households displaced, three found houses within two blocks of their original residence, one left Pennsylvania, and one moved into a public housing project five blocks away. The benefits of Darien Street gentrification included increased property tax revenues and an improved property quality. However, as with all gentrification processes, one must ask whether these improvements outweigh the displacement and economic evictions that they brought about.
Gentrification has gained attention over the last 50 years, as sociologists attempt to explain the influx of middle-class people to cities and neighborhoods and the displacement of lower-class working residents. Gentrification occurs when wealthier people buy or rent property in low-income or working class neighborhoods, driving up property values and rent. While it brings money into blighted urban areas, it often comes at the expense of poorer, pre-gentrification residents who cannot afford increased rents and property taxes .
The first urban pioneers in a gentrifying neighborhood may have lower incomes, but possess the cultural capital (e.g., education) characteristic of suburban residents. They are often socially and professionally dominant while economically marginalized. Partially due to their age and low-incomes, these individuals frequently reside in households with roommates and are more tolerant of the perceived evils of the city, such as crime, poor schools, and insufficient public services. Thus, they are willing to move into marginal neighborhoods. When the number of urban pioneers reaches such a critical mass, it attracts business investment and new amenities such as bars, restaurants, and art galleries. Once the urban pioneers and businesses have taken the financial risk out of the community, risk-averse investors and residents may enter the newly gentrified neighborhood. Renewed business attracts more investment capital and new residents, increasing local property values. Ironically, upon full gentrification, the urban pioneers are frequently evicted as rents and taxes rise, and the young, poor professionals can no longer afford to live in the area.
Gentrification is often resisted by those displaced by rising rents . However, while protests have an economic dimension, claims are usually articulated as a loss of culture or dismay over the homogenization and flattening of a formerly diverse neighborhood: gentrification generally increases the proportion of young, white, middle- to upper-income residents.
Explanations of Gentrification
Demographic
The demographic explanation emphasizes the impact of the baby boomer generation, born after World War II. In the 1970s, this led to a spike in the young adult population, increasing demand for housing. To meet the demand, urban areas had to be “recycled,” or gentrified. The new baby boomer residents departed from the suburban family idea, marrying later and having fewer children; women in the baby boomer generation were the first to enter the workforce in serious numbers. New urban residents were composed of higher, dual-income couples without children, less concerned about space for large families—one of the main draws to the suburbs for their parents. Instead, they were interested in living in cities close to their careers and enjoying the amenities their higher incomes could afford.
Sociocultural
The sociocultural explanation is based on the assumption that values and beliefs influence behavior. It focuses on the changing lifestyles and values of the middle- and upper-classes in the 1970s. At this time, the suburban ideal was falling out of favor; fewer people were moving to suburbs and more were moving back to cities. These first few suburban transplants, or urban pioneers, demonstrated that cities were viable places to live and began developing a type of inner-city chic that was attractive to other baby boomers, which in turn brought an influx of young affluence to inner cities.
Political Economy
Political economic explanations argue new economic or policy incentives contribute to gentrification. In part, the changing political climate of the 1950s and 1960s produced new civil rights legislation, such as anti-discrimination laws in housing and employment and desegregation laws. These policies enabled black families to move out of urban centers and into the suburbs, thus decreasing the availability of suburban land, while integrationist policies encouraged white movement into traditionally black urban areas.
An alternative explanation suggests that developers and government encouraged gentrification with an eye toward profit. Gentrification may be driven by governments hoping to raise property values and increase revenue from taxes. It may be the result of fluctuating relationships between capital investments and the production of urban space. During the two decades following World War II, low rents in the city’s periphery encouraged suburban development; as capital investment moved to suburbs, inner-city property values fell. Developers were able to see that they could purchase the devalued urban land, redevelop the properties, and turn a profit.
Artists move into Williamsburg
In Williamsburg and other parts of Brooklyn, New York, artists have adopted industrial spaces as studios and galleries. This cultural redevelopment is evidence of gentrification.
17.5.5: Shrinking Cities and Counter-Urbanization
Counterurbanization is movement away from cities, including suburbanization, exurbanization, or movement to rural areas.
Learning Objective
Analyze the reasons for suburbanization and counterurbanization, specifically white flight
Key Points
- White flight is one explanation for widespread counterurbanization in the post-WWII era in the U.S. It refers to the movement of middle and upper-class whites to suburbs to avoid living in areas with high proportions of racial minorities.
- Counterurbanization can lead to shrinking cities. Cities with declining populations experience economic strains as infrastructure exceeds the needs of a shrinking population and costs more per capita than during the city’s peak.
- Several approaches have been employed in attempts to address the problems of shrinking cities. Often these approaches aim to increase urban density.
Key Terms
- exurbanization
-
Exurbanization refers to the process in the 1990s when upper class city dwellers moved out of the city, beyond the suburbs, to live in high-end housing in the countryside.
- urban decay
-
Urban decay is a process whereby a city, or part of a city, falls into disrepair and decrepitude.
- white flight
-
The large-scale migration of whites of various European ancestries, from racially mixed urban regions to more racially homogeneous suburban areas.
Examples
- Baltimore, Maryland is an example of a U.S. shrinking city—its population has decreased by over 300,000 since 1950. As a result, the city has faced immense economic strain in recent decades and has seen a sharp rise in crime and poverty.
- Portland, Oregon is an example of a shrinking city that has successfully used policy to reduce the drainage of economic resources to suburbs, by instituting an urban growth boundary that prevents urban sprawl.
Suburbanization and Counterurbanization
Recently, in developed countries, sociologists have observed suburbanization and counterurbanization, or movement away from cities, which may be driven by transportation infrastructure or social factors like racism. In developing countries, urbanization is characterized by large-scale movements of people from the countryside into cities. In developed countries, people are able to move out of cities while maintaining many of the advantages of city life because improved communications and means of transportation. In fact, counterurbanization appears most common among the middle and upper classes who can afford to buy their own homes.
White Flight
Sociologists have posited many explanations for counterurbanization, but one of the most debated known as “white flight. ” The term “white flight” was coined in the mid-twentieth century to describe suburbanization and the large-scale migration of whites of various European ancestries from racially mixed urban regions to more racially homogeneous suburban regions. During the first half of the twentieth century, discriminatory housing policies often prevented blacks from moving to suburbs; banks and federal policy made it difficult for blacks to get the mortgages they needed to buy houses, and communities used restrictive housing covenants to exclude minorities.
White flight during the post-war period contributed to urban decay, a process whereby a city, or part of a city, falls into disrepair and decrepitude. Symptoms of urban decay include depopulation, abandoned buildings, high unemployment, crime, and a desolate, inhospitable landscape. White flight contributed to the draining of cities’ tax bases when middle-class people left. Urban decay was caused in part by the loss of industrial and manufacturing jobs as they moved into rural areas or overseas, where labor was cheaper.
Suburbanization
In the United States, suburbanization began in earnest after World War Two, when soldiers returned from war and received generous government support to finance new homes. These young men were also interested in settling down, buying their own homes, and achieving independence and a less hectic daily life with a more affordable cost of living than they could find in cities. Thus, suburbs were built—smaller cities located on the edges of a larger city, which often include residential neighborhoods for those working in the area. Suburbs grew dramatically in the 1950s when the U.S. Interstate Highway System was built and automobiles became affordable for middle class families.
Exurbanization
Around 1990, another trend emerged, called exurbanization: upper class city dwellers moved out of the city, beyond the suburbs, to live in high-end housing in the countryside. This exurbanization may be a new urban form. Rather than densely populated centers, cities may become more spread out, composed of many interconnected smaller towns. The history of counterurbanization calls into question depictions of urbanization as a one-way process. The modern U.S. experience has followed a circular pattern over the last 150 years, from a largely rural country, to a highly urban country, to a country with significant suburban populations.
Shrinking Cities
Whatever its causes, counterurbanization has had serious effects on cities. As a result of counterurbanization, some cities are now losing population. These shrinking cities may face serious problems as they attempt to maintain infrastructure built for a much larger population. As cities shrink, residents must contribute more per capita to maintain fixed infrastructure costs (e.g., for roads, sewers, and public transportation). Dispersed neighborhoods that characterize shrinking cities are also a major source of fiscal distress. These cities must still provide services like fire protection and trash pickup to fewer and fewer citizens over a larger geographic distance, raising the per capita cost.
Several approaches have been employed in attempts to address these problems. Often these approaches aim to increase urban density. For example, planners may revitalize core areas, like downtown, to make them more attractive to businesses and residents. Other cities have tried setting an urban growth boundary to limit sprawl, which increases density within the boundary. The boundary generally encompasses the city and its surrounding suburbs, requiring the entire area to work together to prevent urban shrinkage. This method is being used successfully in many cities (such as Portland, Oregon) to maximize returns on infrastructure investments.
Baltimore—A Shrinking City
Baltimore, Maryland is an example of a shrinking American city. Its population has decreased by over 300,000 since 1950, leaving infrastructure for a larger population unused.
