Nehru Government Decision to Discontinue Caste Enumeration (1951)

In 1951, Prime Minister Jawaharlal Nehru's government made the consequential decision to discontinue caste enumeration in India's first post-independence census, with limited exceptions. This decision reflected the government's belief that counting and documenting caste would perpetuate social divisions and undermine the nation-building project of the newly sovereign Indian state. The government explicitly sought to foster a unified national identity by declining to treat caste as a primary census category.

An important exception was carved out for Scheduled Castes (SCs) and Scheduled Tribes (STs), whose continued enumeration was deemed constitutionally necessary to implement protections and affirmative action measures mandated by the Indian Constitution. This selective approach meant that while SC and ST demographics remained systematically tracked, the vast majority of the population—including other backward castes (OBCs) and general castes—fell outside official census documentation of caste identity.

The 1951 discontinuation represented a sharp departure from British colonial census practice, which had included detailed caste enumeration in every decadal census from 1871–72 through 1931. The last British colonial caste census of 1931 had documented 4,147 distinct castes. After 1951, the absence of official caste statistics created lasting data gaps that complicated later efforts to assess and address caste-based inequalities across groups. No comprehensive national caste census was conducted again for over seven decades, though states were permitted to conduct localized surveys for OBC list compilation beginning in 1961.
