Introduction
In a historic policy shift for demographic enumeration in post-independence India, the Union Ministry of Home Affairs on 17 August 2026 officially notified the 40-question questionnaire for the second phase of Census 2027 (Population Enumeration). For the first time since the 1931 Census, caste will be enumerated for all communities across India, expanding beyond the traditional enumeration of Scheduled Castes (SCs) and Scheduled Tribes (STs).
Key Additions to the Census 2027 Questionnaire
The questionnaire introduces 13 new questions compared to the 29 questions deployed during Census 2011:
- Universal Caste Enumeration: Enumerates specific caste/sub-caste identities for all citizens to provide granular empirical data for affirmative action and welfare targeted delivery.
- Digital Assets & Identifiers: Captures data on digital literacy, smart devices, Aadhaar details, Voter ID, bank account ownership, mobile numbers, passport, and driving licence particulars.
- Demographic & Health Specifics: Records parental particulars, permanent address, place of COVID-19 vaccination, and disability categorisation under the Rights of Persons with Disabilities Act, 2016.
- Timeline: Field enumeration commences in August/September 2026 across snow-bound Himalayan regions (Ladakh, Himachal Pradesh, Uttarakhand, J&K) and in February 2027 across the rest of the nation.
