Census 2027: what happened?
A Census is the biggest peaceful exercise any government runs. This time it is digital, and for the first time since 1931 it will count caste. That makes training the enumerators very important.
- The second phase of Census 2027 will count every person in the country.
- In Uttar Pradesh and three other poll-bound States, door-to-door counting starts on 1 December.
- This phase has 40 questions, 13 of them new. Each household takes 20 to 25 minutes.
- Question 10 (C) asks the caste of people who are not Scheduled Caste or Scheduled Tribe. It is typed in an open column. People may also choose “Does not want to declare Caste” or “No Caste”. There is no separate column for Other Backward Classes.
- Question 37 asks for Aadhaar, but it is optional. Aadhaar is not proof of citizenship.
How is the Census done, and why does caste matter?
India’s Census is held under the Census Act, 1948. ‘Census’ is in the Union List of the Seventh Schedule, so only the Centre conducts it. The Registrar General and Census Commissioner of India, under the Ministry of Home Affairs, runs it.
The Census is usually held every ten years. The 2021 Census was put off because of the Covid-19 pandemic, so Census 2027 comes after a gap of 16 years.
Every Census since 1951 has counted Scheduled Castes and Scheduled Tribes, but not other castes. The last full caste count was in 1931, under British rule. The Socio Economic and Caste Census of 2011 was a separate survey, and its caste data was not released in full.
Census 2027 is the first digital Census. Enumerators use a mobile app, and people could also fill in details themselves online (self-enumeration).
How is Census 2027 different?
| Point | Earlier Censuses | Census 2027 |
|---|---|---|
| Method | Paper forms | Mobile app; self-enumeration option |
| Caste | Only SC and ST counted | All castes recorded |
| Aadhaar | Not asked | Asked, but optional |
Which laws and Articles apply?
- Census Act, 1948: the legal basis of the Census; it keeps individual answers confidential.
- Seventh Schedule: ‘Census’ is in the Union List.
- Aadhaar Act, 2016: Aadhaar is proof of identity, not of citizenship or domicile.
- Articles 330 and 332: seats for Scheduled Castes and Scheduled Tribes in the Lok Sabha and Assemblies are based on Census population.
