The 1901 census of India contains a wealth of detail that reflects
some of the preocupations of its age. It contains exhaustive treatments
of issues related to population change and religion and civil condition
and the other matters normally recorded in the census reports. A
major introduction in this census report, not seen in the previous
census reports, was the study of the "anthropometric"
readings of racial characteristics which is introduced into its
discussion of "Caste, Tribe, and Race" in chapter eleven
of the work. There is also a very extensive discussion of the origins
of caste in the census report which has provoked much controversy.
Sir Herbert Risley also wrote a major work on Indian Castes called
The People of India which he published in 1908.
