The 2011 Socio-Economic Caste Census was a large-scale effort to collect information on the socio-economic status of various populations.
It consisted of two parts: a survey of rural and urban families and their ranking based on pre-determined factors, as well as a caste census.
However, only the specifics of people's economic situations in rural and urban homes were made public. The caste information has not yet been made public.
Census vs. SECC: What's the difference:
The Census depicts the Indian population, whereas the SECC is a tool for identifying state assistance recipients.
Because the Census is governed by the Census Act of 1948, all data are considered private, whereas the SECC collects personal information that can be used by government departments to grant or deny benefits to households.
