What is the age structure of a population explain how it affects population growth and economic growth?
Age structure data allow the rate of growth (or decline) to be associated with a population’s level of economic development. For example, the population of a country with rapid growth has a triangle-shaped age structure with a greater proportion of younger individuals who are at or close to reproductive age.
