If a country's fertility falls sharply to a low level but population is still projected to grow for the next 20 years, what is the main reason?

Answer and explanation

Correct answer: Demographic momentum from a previously large young population

Population can continue to grow even after fertility becomes low because population structure changes slowly. If earlier generations contained many children, that large young population will later enter the reproductive ages. Even if each person has fewer children, the total number of potential parents can remain high enough for births to exceed deaths for some time.

This continuing effect is called demographic momentum. It is caused by the previously large youthful population, not by a zero death rate, guaranteed positive migration, or an expanding land area. A country may therefore experience population growth for decades after fertility falls below replacement level. Hence option A is correct. The other choices either make an absolute claim or do not explain the age structure that produces continued growth.
