Age structure of a population is the distribution of people of various ages. It can take a variety of forms, depending on the birth and death trends within the population. If the age distribution is plotted for the population, the resulting structure is called an age pyramid.

It is common in demography to split the population into three broad age groups: children and young adolescents (under 15 years old) the working-age population (15-64 years) and. the elderly population (65 years and older)

An age structure diagram is a model that predicts the population growth rate by a shape. It shows a comparative ratio of males to females and the bars show various age groups from infants to adolescents to reproductive and post-reproductive stages.

Example of an age structure with a diminishing population People aged 30-44 (upper reproductive years) make up 19% of the population; people aged 15-29 (lower reproductive years) make up 15% of the population; and people aged 0-14 (pre-reproductive years) make up just 13% of the population.

In this diagram, the ages are arranged so that age ranges are grouped together, for example: 0 ? 4 years, 5 ? 9 years, and so on. The population of each group is represented as a bar extending from a central vertical line, with the length of each bar dependent upon the total population for that particular group.

Age structure: The composition of a population in terms of the proportions of individuals of different ages; represented as a bar graph with younger ages at the bottom and males and females on either side.
