Frequently Asked Questions
What is the difference between birth rate and death rate?
Birth rate measures the number of live births per 1,000 people annually, while death rate measures the number of deaths per 1,000 people annually. Together, they determine natural population growth.
Why is the declining child sex ratio in India a major concern?
A declining child sex ratio indicates deep-rooted gender discrimination, female foeticide, and son meta-preference, which leads to severe social imbalances in the future.
What does demographic dividend mean for India?
It refers to the economic advantage gained when India has a high proportion of working-age people (15-64 years) compared to dependents, provided proper education, health, and employment are given.
