Demographic Transition Theory
The Demographic Transition Model (DTM) describes the historical shift from high birth and death rates to low birth and death rates as societies industrialise. Most developed and rapidly developing states pass through a fourth stage where birth rates fall below death rates.
- India's southern states are in Stage 4 (low birth rate, low death rate), while AP's TFR of 1.5 mirrors patterns seen in South Korea (0.72 in 2023) and Japan — the most advanced cases of demographic decline.
- The "dependency ratio" worsens as elderly populations grow relative to the working-age population, straining pension systems, healthcare, and economic output.
- Pro-natalist policies (birth incentives) have shown mixed results globally — South Korea has spent over $200 billion on incentives with negligible TFR improvement.
