DEFINITION
The distribution of the
population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a
population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the
health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult
population unable to find employment can lead to unrest.
