"However, the seed of the debate on the differential population growth rates of the Hindus and Muslims was planted in the undivided India itself. Kingsley Davis, an eminent demographer, was one of the first to raise a debate on the Hindu-Muslim population growth rates in the sub- continent. In his famous book “The Population of India and Pakistan” (1951), he presented before the world the fact that Muslim fertility was higher than the Hindu fertility. For instance, the decline in the proportion of the Hindus from 75.1 per cent to 72.9 per cent in between the censuses of 1881 and 1901 (Davis, 1951) created strong reaction and fear among the Hindus that the Muslims would become the majority population in India in the future. Numerous research and review studies have been done on this area since then. But there seems to be no end to this highly debated topic and it still remains a very popular area for research studies among the research scholars and population scientists."
