evidence: The fertility rate of Hindu households fell from 2.6 in the last survey in 2005-06 to 2.1, the level at which a population is said to be able to replace itself from generation to generation without migration. [...] Predictably, when looking at the fertility rate of the different wealth quintiles (onefifths of the population), the section with the lowest income had the highest number of children at 3.2 and the richest had the least, 1.5. Scheduled tribes, the least developed among social categories, had the highest fertility rate of 2.5, followed by 2.3 for scheduled castes and 2.2 for other backward classes. The upper castes had the lowest fertility rate of 1.9. The younger the women, the lower the mean number of children born to them, evidence of the progress over the last two decades in bringing down the total fertility rate. The TFR for Muslim women aged 40-49 was the highest at 4.2 and it was the lowest for Jain women of the same age at 2.2. Hindu women of this age group had the second highest TFR of 3.1.
