The Indian government has announced the 16th Census of India will occur in two phases, with reference dates set for March 1, 2027, for most parts of the country, and October 1, 2026, for snow-bound and remote regions like Ladakh, Jammu & Kashmir, Himachal Pradesh, and Uttarakhand. This Census will include the first nationwide caste enumeration since 1931.
