Demographic Transition in India
India is currently in the late second to early third stage of the Demographic Transition Model (DTM), with declining birth rates while death rates have already fallen substantially.
Demographic Transition Model Applied to India
| Stage | Period (approx.) | Birth Rate | Death Rate | Population Growth | India's Experience |
|---|---|---|---|---|---|
| Stage 1 (Pre-transition) | Before 1920s | High (~49/1000) | High (~48/1000) | Very low/stagnant | Famines, epidemics kept death rate high |
| Stage 2 (Early transition) | 1920s-1970s | High but slowly declining | Rapidly declining | Rapid growth ("population explosion") | Healthcare improvements, disease control |
| Stage 3 (Late transition) | 1970s-present | Declining | Low | Slowing growth | Family planning programs, urbanisation, female education |
| Stage 4 (Post-transition) | Some southern states | Low | Low | Very low/stable | Kerala, Tamil Nadu, Andhra Pradesh near replacement fertility |
