Population & Migration unit test
A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

7 ptsONE STIMULUS. A population pyramid for Japan, 2021 (US Census Bureau International Database), divides the population by sex into five-year cohorts. Its shape: a narrow base — the youngest cohorts (0–4, 5–9, 10–14) are markedly smaller than the middle-aged cohorts; bulges around ages 45–54 and 70–74; and a top-heavy structure in which, in the cohorts aged 80 and above, the female bars are roughly twice the length of the male bars (male ≈ 3–4 percent of the population, female ≈ 6–7 percent).
A. Identify the recent trend in fertility shown in the population pyramid.
B. Based on the data shown in the population pyramid, describe the ratio of males to females in the Japanese population age 80 and above.
C. Describe one process that drives urbanization.
D. Describe one factor that may lead to a decrease in total population within a more developed country.
E. Explain how a country’s population pyramid can be used to predict the future needs of the population.
F. Explain why the population pyramid provides limited information about immigration to cities in Japan.
G. Explain the degree to which a country’s population growth rate may be affected by a pronatalist policy. (Indicate the degree — low, moderate, high — and explain.)
