Q.Why is the study of demography important for an economy like India?

Population is not just a social fact; it directly shapes an economy's productive capacity and its needs.

A growing or ageing population changes how much a country can produce, how large its domestic market is, and how much it must spend on schools, hospitals, and employment schemes — all central questions for planning.

The study of demography is important for an economy like India for several interconnected reasons. First, the size and age structure of the population determine the available labour supply — the working-age population is the pool from which the economy draws its workforce. Second, population size and its growth rate shape the size of the domestic market for goods and services, influencing investment decisions by firms. Third, demographic data collected through the Census and vital registration systems allow governments to undertake resource planning — deciding how many schools, hospitals, houses, and jobs will be needed in the years ahead. Fourth, demography reveals the quality of the population — its health, education, and skill levels — which is the essential starting point for planning Human Resource Development. For a country like India, with a historically young population and a still-evolving demographic transition, these demographic facts directly determine whether population growth becomes a demographic dividend or a demographic burden.

A common gap is discussing only population 'problems' (overcrowding, unemployment) without recognising population as also a positive economic resource when it is healthy and skilled.
