A population’s growth rate is strongly influenced by the proportions of individuals of particular ages. With knowledge of this age structure, population growth can be more accurately predicted. Age structure data allow the rate of growth (or decline) to be associated with a population’s level of economic development.

How does age structure influence population growth?

D Age structure



Growing populations generally have larger proportions of individuals in younger age-classes, whereas declining populations usually have smaller proportions of individuals in these age classes. Stable populations usually have relatively more individuals in reproductive age-classes.
