4. Sociology and Everyday Life: The Immigration Debate
All “unauthorized immigrants” in the United States entered the country illegally.

5. Sociology and Everyday Life: The Immigration Debate
Most people migrate to another country because of “push” factors that make them unhappy in their country of origin, such as poor economic conditions, political unrest, or war.

6. Sociology and Everyday Life: The Immigration Debate
U.S. immigrant are just as likely to have college degrees as are native-born Americans.

7. Sociology and Everyday Life: The Immigration Debate
Immigrants increase unemployment and lower wages among native workers.

8. Sociology and Everyday Life: The Immigration Debate
Most children living in undocumented immigrant families were born in the United States and are, therefore, U.S. citizens.

9. Sociology and Everyday Life: The Immigration Debate
When a Gallup poll asked Americans if illegal immigrants mostly take jobs that Americans want, or if they mostly take low-paying jobs that Americans don’t want, the majority of Americans indicated that they believe that most undocumented immigrants take low- paying jobs that Americans don’t want.

10. Sociology and Everyday Life: The Immigration Debate
To become a naturalized U.S. citizen, immigrants must pass a basic test on English and U.S. civics.

11. Sociology and Everyday Life: The Immigration Debate
Foreign-born non-U.S. citizens who marry a U.S. citizen are automatically granted U.S. citizenship.

12. Demography: The Study of Population
Demography is a subfield of sociology that examines population size, composition, and distribution.

13. Figure 15.1 Growth in the World’s Population, 2012

14. Fertility is the actual level of childbearing for an individual or a population.
The crude birth rate is the number of live births per 1,000 people in a population in a given year.

15. Mortality is the incidence of death in a population.
The crude death rate is the number of deaths per 1,000 people in a population in a given year.

16. Table 15. 1 The Ten Leading Causes of Death in the U. S

17. Migration is the movement of people from one geographic area to another for the purpose of changing residency.
International versus internal
Immigration versus emigration
Push versus pull factors

18. Consider This…
Figure 15.2
Political unrest, violence, and war are “push” factors that encourage people to leave their country of origin. By contrast, job opportunities, such as construction work in the United States, are a major “pull” factor for people from low-income countries.

19. Consider This…
Figure 15.3
This fence between Mexico and the United States has been the subject of extensive media attention and public controversy. Although not a continuous fence, the barriers – combined with a “virtual fence” of sensors and cameras monitored by the U.S. Border Patrol – are designed to prevent illegal migration between the two countries.

20. Polling Question
Should immigration be controlled? How?

21. Population composition is the biological and social characteristics of a population, including age, sex, race, marital status, education, occupation, income, and size of household.
The sex ratio is the number of males for every hundred females in a given population.
A population pyramid is a graphic representation of the distribution of a population by sex and age.

22. Figure 15.4 Population Pyramids for Mexico, Iran, the U.S., and France

23. Population Growth in Global Context
The Malthusian perspective: the power of population is infinitely greater than the power of the earth to produce subsistence for man.

24. The Marxist perspective: overpopulation occurs because capitalists desire to have a surplus of workers in order to suppress wages and force workers concerned about losing their livelihoods to be more productive.

25. The Neo-Malthusians perspective
Zero population growth is the point at which no population increase occurs from year to year.

26. The demographic transition is the process by which some societies have moved from high birth and death rates to relatively low birth and death rates as a result of technological development.

27. Polling Question
What causes birth rates and death rates to change?

28. Figure 15.5 The Demographic Transition

29. A Brief Glimpse at International Migration Theories
Neoclassical economic approach
New households economic of migration approach
Split-labor-market theory
World systems theory
Network theory
Institutional theory

30. Urbanization in Global Perspective
Preconditions for city development
A favorable physical environment
An advanced technology
A well-developed social organization

31. Postindustrial Cities
Preindustrial Cities
Small, limited migration
Industrial Cities
Employment opportunities, increased size
Postindustrial Cities
Service/information sector, rapid expansion

32. Perspectives on Urbanization and the Growth of Cities
Ecological Models
The concentric zone model
Invasion is the process by which a new category of people or type of land use arrives in an area previously occupied by another group or type of land use.
Succession is the process by which a new category of people or type of land use gradually predominate in an area formerly dominated by another group or type of land use.
Gentrification is the process by which members of the middle and upper-middle classes move into a central-city area and renovate existing properties.

33. Ecological Models The Sector Model The Multiple Nuclei Model
Contemporary Urban Ecology

34. Figure 15.7 Three Models of the City

35. Consider This…
Figure 15.8
Boston’s South End has recently experienced gentrification. Why do some social theorists disagree on the positive and negative effects of gentrification on communities?

36. Political Economy Models
Both economic and political factors affect patterns of urban growth and decline.
Urban space has both an exchange value and a use value.
Both structure and agency are important in understanding how urban development takes place.

37. Figure 15.9 The Value of Urban Space

38. Consider This…
Figure 15.10
How do gated communities increase the division between public and private property in the United States?

39. Symbolic Interactionist Perspectives
Simmel: urban life shapes people’s thoughts and actions
Wirth: urbanism is a way of life
Gans: everyone experiences cities differently

40. Problems in Global Cities
Rapid population growth
Urban agglomeration
Rural-to-urban migration

41. Polling Question
What is the biggest problem facing urban areas?

44. Urban Problems in the United States
Cities and suburbs
Race/ethnicity
Social class
Edge cities and exurban areas
Fiscal crises in cities

45. Consider This…
Figure 15.13
Despite an increase in telecommuting and more-diverse employment opportunities in the high-tech economy, our highways have grown increasingly congested. Can we implement measures to reduce the problems of urban congestion and environmental pollution, or will these problems grow worse with each passing year?

46. Rural Community Issues in the United States
Increased migration into rural areas
Fiscal challenges for agriculture
Limited economic opportunities
Limited access to services
