Population Composition - Lesson Summary

Age composition indicates the number of people that belong to different age groups.

The population of a nation is generally grouped into three broad categories:
  • Children
  • Working age adults
  • Aged

Dependency ratio is the ratio of the dependent population to the working-age population of the country. The percentage of children and the aged affect the dependency ratio.

Sex ratio is the ratio of males to females in a population. It is calculated as the number of females per 1000 males of the population. The sex ratio in India has always remained unfavourable to females.
