Age structure can commonly be represented graphically through which medium?

Answer and explanation

Correct answer: Population pyramid

A population pyramid is a graph that presents the age and sex composition of a population. Age groups are usually arranged from younger ages at the bottom to older ages at the top. The two sides commonly represent males and females, allowing the viewer to compare their numbers in each age group. The overall shape can show whether a population is youthful, stable, or ageing.

A broad base generally suggests many children and relatively high fertility, while a narrower base may indicate lower fertility. A wider upper part can reflect a larger elderly population and longer survival. Thus option A is correct because the population pyramid is specifically designed to display age structure, often together with sex structure. A rainfall map shows precipitation, a soil profile shows soil layers, and an ocean map represents marine features; none is the standard graph for age distribution.
