Why can a country's total population continue to grow for some time even after the birth rate declines?

Answer and explanation

Correct answer: Because large young cohorts may enter reproductive ages, maintaining population momentum

The governing concept is population momentum, which arises from the existing age composition rather than from fertility alone. If a country previously had high fertility, it may contain a very large group of children and adolescents. As this group reaches reproductive ages, the number of potential parents becomes large. Consequently, even if the average number of births per woman declines, the total number of births can remain substantial for several years or decades. Option A is therefore correct. Option B is false because a lower birth rate does not itself produce more births. Option C is biologically impossible, and option D ignores the major influence of age structure on future growth. The timing and size of earlier cohorts are therefore essential to understanding population change.
