Frequently Asked Questions
What is the demographic dividend and why is it important for India?
The demographic dividend refers to the economic growth potential that can result from shifts in a population's age structure, specifically when the share of the working-age population (15-64) is larger than the non-working-age share, giving India a competitive edge.
Why is the child sex ratio declining in India?
The declining child sex ratio is primarily driven by son preference, cultural prejudices, and the illegal misuse of pre-natal diagnostic techniques for sex-selective abortion.
What is the difference between birth rate and growth rate?
Birth rate is simply the number of live births per 1,000 people in a year, whereas population growth rate takes into account births, deaths, and migration to show the overall net change in population size.
