If the upper part of a country's population pyramid is widening over time, what does it indicate?

Answer and explanation

Correct answer: More people are surviving to older ages

A population pyramid shows the age composition of a population. Its upper part represents older age groups, while the lower part represents children and the middle generally represents working ages. If the upper section becomes wider over time, a larger share of people is reaching and surviving through older ages. This usually reflects longer life expectancy and lower mortality at older ages.

The widening does not indicate rising infant mortality or sharply increasing fertility. It also does not mean that only children are increasing; in fact, the evidence points to a growing elderly population. The exact shape can be influenced by migration and past birth patterns, but the most direct interpretation of a broader upper part is improved survival to old age. Therefore, option A is the correct choice.
