Frequently Asked Questions
What is the difference between population growth and population change?
Population growth refers specifically to an increase in the number of inhabitants over time, whereas population change can be either positive (growth) or negative (decline).
Why is the density of population high in the Northern Plains of India?
The Northern Plains have fertile alluvial soil, flat terrain, abundant water supply, and favourable climate which support agriculture and high population concentration.
What do you mean by the demographic dividend?
It is a surge in 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 years) is larger than the non-working-age share.
