In Religious Demography of India, Bajaj, Joshi, and Srinivas analyze Indian census data from 1871 to 1991, in order to assess the shifts in demography in religious identity in India and on that basis make predictions about the future. They look closely into the data regarding the various states of India and even the individual districts of those states. The book, coming in two parts, invites readers to study the data for themselves: the first 175 pages offer an analysis of census data, but pp. 179-346 are comprised entirely of tables reporting data, thus enabling readers to make up their own minds.
