What is the significance of age-structure?

Age structure represents the number of people of different age groups. It is an important indicator of population composition as it represents the distribution of the population based on age, which further helps in gauging the trend of the population.

A greater proportion of the population above 60 years represents an ageing population, which requires more expenditure on health care facilities, and a high proportion of the young population would mean a high birth rate and youthful population.
