One would expect to find a population with a relatively older age structure in
less developed countries
more developed countries
countries with high death rates

A country is likely to be in which stage of the demographic transition when its birth rate significantly exceeds its death rate?
Question 4 Explanation:
The correct answer is (B). Stage 1 has high birthrates and high death rates. Stage 2 has high birth rates and declining death rates. In stage 3, both birth rates and death rates decline, and they are both low in stage 4. In stage 5, birth rates are so low that the elderly outnumber the young.
A country in 2017 with a natural increase rate at or about zero is at which stage of the demographic transition?
Question 5 Explanation:
The correct answer is (D). The natural increase rate equals the crude birth rate minus the crude death rate. It would be about zero in stages 1 and 4, but stage 1 countries no longer exist. Therefore, the correct answer is stage 4.
The population pyramid above shows a country at which stage of the demographic transition?

A country with a natural increase rate at or about zero is likely to have a
low fertility rate, low standard of living, and few people employed in agriculture
low fertility rate, low standard of living, and many people employed in agriculture
low fertility rate, high standard of living, and few people employed in agriculture
low fertility rate, high standard of living, and many people employed in agriculture
high fertility rate, high standard of living, and many people employed in agriculture
Question 7 Explanation:
The correct answer is (C). A lower fertility rate indicates a high standard of living, so (A) and (B) can be eliminated. A high fertility rate indicates a low standard of living, so (E) and can be eliminated. A country with a high standard of living will have access to technology, and therefore, will have relatively few people employed in agriculture, which means (C) is the correct answer.
Countries at the end of the demographic transition are likely to have problems caring for ____________ but can solve that problem by accepting ____________.
young children, emigrants
young children, immigrants
elderly, universal healthcare
Question 8 Explanation:
The correct answer is (D). Countries in stages 4 or 5 have declining birthrates, which means the percentage of elderly within the population increases. That fact eliminates (A) and (B). While universal healthcare (E) might be appealing, there would not be enough workers to pay the taxes to support it in a stage 5 country. Countries that accept immigrants (D), however, have enough workers to support the elderly.
