Demography: The Study of Population
Demography: scientific study of population
Fertility: level of reproduction in a society
Sociologists focus on social factors that influence population rates and trends.
4
Demography: The Study of Population
– Malthus held that world’s population was growing more rapidly than the available food supply
• Argued food supply increases in an arithmetic progression, whereas population expands by geometric progression
– Malthus advocated population control
Malthus’s Thesis and Marx’s Response
5
Demography: The Study of Population
• If society were well ordered, increases should lead to greater wealth, not hunger and misery
• Linked overpopulation to unequal distribution of resources
Malthus’s Thesis and Marx’s Response– Marx saw no special relationship
between world population and the supply of resources
6
Demography: The Study of Population
– Census: enumeration, or counting of a population
– Vital Statistics: records of births, deaths, marriages, and divorces gathered through a registration system maintained by government
Studying Population Today
7
Demography: The Study of Population
– Death Rate: number of deaths per 1,000 population in a given year
– Infant Mortality Rate: number of deaths of infants under one year of age per 1,000 live births in a given year.
Elements of Demography
8
Demography: The Study of Population
– Life Expectancy: median number of years a person can be expected to live under current mortality conditions
– Growth Rate: difference between birth and deaths, plus the difference between immigrants and emigrants.
Elements of Demography
9
World Population Patterns
– Change from high birthrates and death rates to relatively low birth rates and death rates
– Typically viewed as a three-stage process:
Pre-transition stage
Transition stage
Post-transition stage
Demographic Transition
10
World Population Patterns
– Momentum toward growing world population well-established• Developing nations face prospect of
continued population growth, since substantial proportion of their population is approaching child bearing years
Population Pyramid: special type of bar chart that shows distribution of population by gender and age
The Population Explosion
11
World Population Patterns
12
World Population Patterns Figure 15.1: Demographic Transition
13
World Population Patterns Figure 15.2: Population Structure of Afghanistan and the United
States, 2005
14
Fertility Patterns in the United States
– The baby boom was not a return to large families, but rather decrease in number of childless marriages and one-child families
– The baby boom represents the most recent period of high fertility in the United States
The Baby Boom
15
Fertility Patterns in the United States
– Fertility rate of the U.S. remained low over the last two decades
– Still experiencing population growth• Momentum built into our age structure by
the postwar population boom• Continued high rates of immigration
Stable Population Growth
16
Fertility Patterns in the United States
Stable Population Growth
Zero Population Growth (ZPG): state of a population in which the number of births plus immigrants equals the number of deaths plus emigrants
17
Population and Migration
Migration: relatively permanent movement of people with the purpose of changing their place of residence.
Migration usually describes movement over a sizable distance, rather than from one side of a city to another.
18
How Did Communities Originate?
– Early communities were very dependent on physical environment for their food supply
– Horticultural societies, where people cultivated food rather than merely gathering fruits and vegetables, led to dramatic changes in human social organization
Early Communities
19
How Did Communities Originate?
– Had only a few thousand people living within their borders
– Characterized by relatively closed class systems and limited mobility
– Status based on ascribed characteristics, and education limited to elite
Preindustrial Cities
20
How Did Communities Originate?
• Reliance on animal power• Modest levels of surplus• Problems in transportation
and storage of food• Hardships of migration to
the city• Dangers of city life
Preindustrial Cities– Remained small due to:
21
How Did Communities Originate?
– Industrial City: Based on very different principles of social organization than preindustrial cities
• More open class system and social mobility
Industrial and Postindustrial Cities
22
How Did Communities Originate?
– Urbanism: relatively large and permanent settlement leads to distinctive patterns of behavior
Industrial and Postindustrial Cities– Postindustrial City: Global finance and
electronic flow of information dominate the economy
23
Urbanization
– Human Ecology: interrelationships between people and their spatial settings and physical environments
– Urban Ecology: focuses on relationships as they emerge in urban areas
Functionalist View: Urban Ecology
24
Urbanization
• Zones illustrate or define growth of urban area over time
Functionalist View: Urban Ecology– Concentric-Zone Theory: center, or
nucleus, of a city is the most highly valued land and each succeeding zone surrounding the center contains other types of land which are valued differently
25
Urbanization
• Metropolitan area may have several centers of development reflecting urban need or activity
Functionalist View: Urban Ecology– Multiple-nuclei theory: all urban
growth does not radiate out from a central district
26
Urbanization Figure 15.3: Ecological Theories of Urban Growth
27
Urbanization
– New urban sociology: considers the interplay of local, national, and worldwide forces and their effects on local space
– World Systems Analysis: certain industrialized nations hold a dominant position at the core of global economic system
Conflict View: New Urban Sociology
28
Urbanization
– Peripheral countries tend to be exploited by core nations
Conflict View: New Urban Sociology– Poorer developing countries are on
periphery of global economy
29
Urbanization
30
Types of Communities
– Urban Dwellers• Gans distinguishes five types of people
found in our cities:– Cosmopolites– Unmarried and
childless people– Ethnic villagers– The deprived– The trapped
Central Cities
31
Types of Communities
– Issues Facing Cities• Crime• Pollution• Schools• Inadequate transportation
Central Cities– Urban Dwellers
• Defended neighborhood refers to people’s definitions of their community boundaries
32
Types of Communities
– Leaders, policymakers and advocates first identify community’s strengths and then seek to mobilize those assets
Asset-Based Community Development (ABCD Approach)
Helps communities recognize human resources they might otherwise overlook
33
Types of Communities
– Any community near a large city
– Three social factors differentiate suburbs from cities:• Less dense than cities• Private space• More exacting building codes
Suburbs
34
Types of Communities
– Diversity in the suburbs• The suburbs contain significant number of
low-income people from all backgrounds
Suburbs– Suburban Expansion
• Suburbanization most dramatic population trend in the United States during 20th century
35
Types of Communities
– 21% of U.S. population live in rural areas
– Farm residents now represent less than 1% of U.S. population
– Shift to single, large business also creates problems
Rural Communities
36
Culture and Health
Culture can also influence the relative incidence of a disease or disorder.
Culture contributes to differences in medical care as well as how health is defined
37
Sociological Perspectives on Health and Illness
– State of complete physical, mental, and social well-being• Not merely the absence of disease and
infirmity
– Represents ideal rather than precise condition
Health
38
Sociological Perspectives on Health and Illness
– Being sick must be controlled so that not too many people are released from their societal responsibilities at any one time
Sick role:Societal expectations about attitudes and behavior of a person viewed as being ill
Physicians function as “gatekeepers” for the sick role.
Functionalist Approach
39
Sociological Perspectives on Health and Illness
– Critical of growing role of medicine as major institution of social control
– Argues that medicine is a regulating mechanism and manifests social control by:• Expanding its domain of expertise• Retaining jurisdiction over many health
care procedures
Conflict Approach
40
Sociological Perspectives on Health and Illness
• Poor areas tend to be underserved• Brain drain: immigration to U.S. and other
industrialized nations of skilled workers, professionals, and technicians desperately needed in home countries
Conflict Approach– Inequities of Health Care
41
Sociological Perspectives on Health and Illness
– Studies the roles played by health care professionals and patients
– Asserts that patients may play an active role in the positive or negative outcomes of their health
Interactionist Approach
42
Sociological Perspectives on Health and Illness
– The designations healthy and ill generally involve social definition by others
– Disagreements continue in the medical community over whether a variety of life experiences are illnesses or not
Labeling Approach
43
Culture and Health Figure 15.4: Infant Mortality Rates, 2002
44
Social Epidemiology and Health
– Social Epidemiology: study of distribution of disease, impairment, and general health status across a population
– Incidence: number of new cases of specific disorder occurring within given population during stated period of time, usually a year
– Prevalence: total number of cases of specific disorder that exist at given time
Social Epidemiology and Health
45
Social Epidemiology and Health
– Clearly associated with differences in morbidity and mortality rates
– Class linked to health by:• Crowded living conditions• Substandard housing• Poor diet• Stress• Lack of health insurance
█Social Class
46
Social Epidemiology and Health
– Health profiles of racial and ethnic groups reflect social inequality evident in United States
– Poor economic and environmental conditions manifested in high morbidity and mortality rates for these groups
Race and Ethnicity
47
Social Epidemiology and Health Figure 15.5: Percent of People without Health Insurance, 2003
48
Social Epidemiology and Health
– When compared with men, women live longer, but as a group appear to be in poorer health than men
– Women live longer due to:• Lower rate of cigarette smoking• Lower consumption of alcohol• Lower rates of employment in certain
occupations
Gender
49
Social Epidemiology and Health
– Most older people in the United States have at least one chronic illness
– Older people vulnerable to certain types of mental health problems
– Older people use more health services than younger people

Social Policy and Health
• In many developing nations, health care issues center on very basic needs of primary care
• Industrialized nations face issues related to the accessibility and affordability of health care
Financing Health Care Worldwide– The Issue
51
Social Policy and Health
• The U.S. is only Western industrial democracy that does not treat health care as basic right
• National Health Insurance: general term for legislative proposals that focus on ways to provide the entire population with health care services
Opponents of national health insurance insist it would be costly and lead to significant tax increases.
Financing Health Care Worldwide– The Setting
52
Social Policy and Health
• Conflict theorists suggest that health care system resists basic change
– Those who receive substantial wealth and power through the workings of an existing institution have strong incentive to keep things as they are
• The health care system undergoing “corporatization”
Financing Health Care Worldwide– Sociological Insights
53
Social Policy and Health
• Major changes occurring• More people enrolled in managed care plans,
which limit patient’s choice of physicians and treatments but cover most medical costs
• There are growing concerns about the quality of health care provided by managed care plans
• Many industrial countries paying greater attention to unequal health care delivery
