|---|---|---|
| Phase I β Stagnant | Before 1921 | High birth rate + high death rate = slow growth; 1921 = “Year of Great Divide” |
| Phase II β Steady Growth | 1921β1951 | Death rate declining; birth rate still high; moderate growth |
| Phase III β Rapid Growth | 1951β1981 | Population explosion; death rate fell sharply; birth rate still high |

π Demographic Dividend
- Demographic Dividend = economic growth potential from large working-age population (15β64 years)
- India’s demographic dividend window: 2020β2040
- ~65% of India’s population is below 35 years
- Provides large labour force, higher savings, increased consumption
- India needs to invest in education and skill development to harness this
- TFR (Total Fertility Rate) = 2.0 (2020) = below replacement level (2.1)
