If the share of children increases, which part of the population pyramid will broaden first?

Answer and explanation

Correct answer: Base

In a population pyramid, age groups are arranged vertically. The youngest people, including children, are placed at the bottom, so the bottom is called the base. If the proportion of children increases, the bars representing the youngest ages become longer and the base becomes broader.

The top represents elderly groups, and the middle mainly represents adult or working-age groups. An increase in children does not immediately broaden the top, because older groups are a different part of the age distribution. Thus option A follows directly from how a population pyramid is constructed. A broad base may also suggest higher fertility or a younger population, although the exact interpretation depends on the whole pyramid and the time period considered.
