India's census was due in 2021 and postponed because of the Covid-19 pandemic. It is now Census 2027, the 16th census exercise and the eighth since Independence, conducted by the Registrar General and Census Commissioner under the Ministry of Home Affairs, under the Census Act, 1948. It is being carried out in two phases, and it will be India's first predominantly digital census, with data collected through mobile applications and an online self-enumeration option. The Union Cabinet has approved 11,718 crore rupees for the exercise, which is expected to be the largest headcount in India's history.
Phase I, the house listing and housing census, ran from 1 April to 30 September 2026 across states and union territories, collecting data on buildings, homes, amenities, and household assets, with a 30-day house-listing window in each state preceded by a 15-day self-enumeration window. Phase II, population enumeration, records individual details such as age, gender, occupation, literacy, migration, and fertility, and, for the first time since 1931, it will include caste enumeration. The government has said caste-related questions will be notified in advance.
The dates for Phase II were notified on 30 October 2026. For most of the country, households can self-enumerate online from 10 to 24 January 2027, enumerators will go house to house from 25 January to 28 February 2027, and a revisional round follows from 1 to 5 March 2027, with a reference date of midnight on 1 March 2027. The schedule differs elsewhere: snow-bound areas of Ladakh, Jammu and Kashmir, Himachal Pradesh, and Uttarakhand were counted in September 2026 with a reference date of 1 October 2026, while Goa, Uttar Pradesh, Punjab, and the rest of Uttarakhand follow a December 2026 to January 2027 window with a reference date of 5 January 2027. Manipur is excluded until further declaration, and no alternative schedule for it had been announced at fact-check time.
Why the census matters goes beyond counting. Delimitation of constituencies, allocation of funds, reservation policy, and welfare targeting all depend on census data, which is why the 16-year gap since 2011, the caste question, and the digital method are all politically significant. A census is also a test of state capacity: it must reach every household, including those that do not want to be found, and its credibility depends on whether people believe their answers will be used for services rather than against them.
Key takeaways
- Census 2027 is India's first predominantly digital census, in two phases: house listing (April–September 2026) and population enumeration (January–February 2027 for most of India).
- Population enumeration includes caste enumeration for the first time since 1931, with a reference date of 1 March 2027 for most of the country.
- Staggered schedules apply to snow-bound and poll-bound areas, and Manipur is excluded until further declaration.
Why it matters for civil studies
Census data underpins representation, finance, and welfare, so its design, timing, and public trust are constitutional questions, not just statistical ones.
Think it through
Does including caste enumeration strengthen evidence-based policy, or does it deepen the very divisions it measures?
