Census History & Methodology in India

The decennial Census of India is one of the largest administrative and demographic data exercises in the world. The first non-synchronous population count was conducted in 1872 under Viceroy Lord Mayo, followed by the first complete, synchronous census in 1881 supervised by W.C. Plowden. Post-independence, the census gained statutory backing under the Census Act of 1948. Administered by the Office of the Registrar General and Census Commissioner of India under the Ministry of Home Affairs, census operations follow a two-phase methodology: House Listing and Housing Census, followed by Population Enumeration, capturing critical socio-economic parameters.
