Demography and Aging
What is “demography”? n n Demography is the study of populations Counting and describing people n n Age, sex, income, marital status… Demographers calculate n n n life expectancy birth and fertility rates average at marriage…
Three basic processes affect population n Fertility Mortality Migration n Many factors affect these processes n n n Economic development, technology, religious and cultural values…
“Population aging” n 1. How do we measure this?
Indicators of population aging n Greater numbers of older people n Higher median age n A higher percentage of our population is “old” n n In 1900, 4% of US population was 65+ In 1996, just under 13%
n 2. What was the U. S. “baby boom” and when did it take place? n (and why do we care? !)
3. Which age group in the U. S. population is growing fastest?
What is causing this shift in age? n Increasing life expectancy n n Declining birth rates n n =changes in mortality =changes in fertility 4. Which of these is most important?
Fertility rates, 1950 and 2005 n n n Africa: 6. 7 -> 5. 1 Asia: 5. 9 -> 2. 5 Latin American / Caribbean: 5. 9 -> 2. 6 North America: 3. 5 -> 2. 0 Europe: 2. 7 -> 1. 4
5. What explains gains in life expectancy?
6. Gender distribution n Are the majority of U. S. older adults men or women? Why?
Population pyramids n n Also known as “age-sex pyramid” or age structure diagram Shows how the “shape” of population changes n Often from pyramid (more younger people at the bottom, few old people) to rectangle (more equal distribution between ages)

Global Aging: Which countries are the “oldest”?
Percent Aged 65 and Over: 2000
Percent Aged 65 and Over: 2030
Uneven geographic distribution n Differences in fertility, mortality, and migration create different population characteristics in different areas n n Differences between countries Differences within countries n n n Which places in the U. S. are “old”? Which places are “young”? What difference does that make? ?

Other demographic trends… n n n Increasing diversity Increasing levels of education Changes in families
Distribution by Race and Ethnicity
Education, Percentage and Level 65+
Education, Percentage by Race and Hispanic Origin
Changes in families… n …affect who is available to take care of an older person. n n n Smaller families Marriages and births at later ages Increased likelihood of divorce More blended families …and the living arrangements of older people.

7. Who helps us when we are old? n Dependency ratios n n n Old age dependency ratio - % of population 65+ compared to % of population 18 to 64 (the “workers”). Fewer workers supporting more older people So old age dependency ratio is INCREASING
Other ratios… n Childhood dependency ratio - % population age 0 -17 compared to % population 18 to 64. n n This is DECLINING Overall dependency ratio - STABLE
