Historical Overview of Census in India
Pre-Independence:
• For the first time, a census was conducted in the towns of Allahabad (1824) and Banaras (1827-28) by James Prinsep.
• The first complete census of an Indian city was conducted in 1830 in Dacca by Henry Walter.
• The first nationwide census was undertaken in 1872 under Lord Mayo.
• The first modern synchronous census covering all of British India (except Kashmir) was undertaken in 1881 by W.C. Plowden, initiating the decennial census followed to the present day.
• The 1931 census was the last to record comprehensive caste data. This caste data was used by the Mandal Commission to recommend 27% reservations for Backward Classes.
Post-Independence:
• The 1951 census was the first to be conducted under the Census Act, 1948. It excluded caste enumeration for the general population except for SC and ST population. Now, the focus shifted to socio-economic parameters like education, literacy, and employment status.
• The National Population Register (NPR), launched in 2010 and updated in 2015, was designed to build a detailed identity database of all usual residents.
• The Socio-Economic and Caste Census (SECC) 2011 was a one-off exercise conducted separately from the main Census.
