Age-Sex Distribution Diagram

Definition

An age-sex distribution diagram, also known as a population pyramid, is a graphical representation that shows the distribution of a population by age and sex. It consists of two back-to-back bar graphs, one for males and one for females, with the youngest age groups at the bottom and the oldest at the top.

Analogy

Imagine an age-sex distribution diagram as a stack of Lego blocks with each block representing a different age group. The width of each block represents the proportion of people in that age group, while the color distinguishes between males and females. When you look at this stack from above, it forms a pyramid shape that tells you about the distribution of ages and sexes in a population.
