evidence: Every religious group in the country has seen its fertility fall, including the majority Hindu population and Muslim, Christian, Sikh, Buddhist and Jain minority groups. Among Indian Muslims, for example, the total fertility rate has declined dramatically, from 4.4 children per woman in 1992 to 2.6 children in 2015, the most recent year for which religion data is available from India’s National Family Health Survey. Muslims still have the highest fertility rate among India’s major religious groups, followed by Hindus at 2.1. Jains have the lowest fertility rate (1.2). The general pattern is largely the same as it was in 1992, when Muslims had the highest fertility rate at 4.4, followed by Hindus at 3.3. But the gaps in childbearing between India’s religious groups are generally much smaller than they used to be. For example, while Muslim women were expected to have an average of 1.1 more children than Hindu women in 1992, the gap had shrunk to 0.5 by 2015. [...] Religion is only one of many factors tied to fertility rates. While this report describes differences in the fertility patterns of major religious groups in India, it cannot measure the full impact of historical and cultural factors on these patterns, nor can it quantify the direct role that religion plays when it comes to fertility and family size.
