Ans:- An interesting way of studying the
population composition of a country is by looking as the populated pyramid,
also called as age-sex pyramid.
A population pyramid shows –

The
total population divided into various age groups, eg., 5 to 9 years, 10 to 14
years.
ii.
The percentage of the total population, subdivides into male and females, in

India
has the largest proportion of person of age 14 years and under in the world. If
health, education and skill development of this young population are taken care
of they will be a great asset to the country.
