Quizplus · Accepted Answer

A population pyramid is a graph that shows the distribution of a population by age and sex. The vertical axis shows the age groups, typically in five-year increments, and the horizontal axis shows the percentage or number of males and females in each age group. The resulting shape of the graph resembles a pyramid, with a wide base representing a high percentage of young people and a narrow top representing a low percentage of elderly people. In this way, a population pyramid can provide insights into a population's age structure, fertility rates, life expectancy, and other demographic trends.
