From Sanjeev Sanyal:
The TFR for rural areas stands at 2.5, but that for urban India is down at 1.8 — marginally below the readings for Britain and the US. An important implication of this is that India’s overall TFR will almost certainly fall below replacement as it rapidly urbanises over the next 20 years.
There continue to be wide variations in the fertility rates across the country. Readings for the southern states have been low for some time, but are now dropping sharply in many northern states.
Tamil Nadu has a TFR of 1.7 but so do Punjab, Himachal Pradesh and Delhi. Uttar Pradesh and Bihar continue to have the country’s highest TFR at 3.1 and 3.5 respectively, but these are also falling steadily.
Demise of the Bhadralok Interestingly, West Bengal has the lowest fertility in the country with a TFR reading of 1.6. The level for rural Bengal is 1.8 but is a shockingly low 1.2 for the cities. This is one of the lowest levels in the world and is at par with Singapore and South Korea.
Do read the whole thing. The net Indian TFR is about 2.3, which given gender imbalance and infant and child mortality is already about replacement rate.
