Census 2027 is India's 16th decennial census and the first-ever digital census, with online self-enumeration via portal se.census.gov.in and inclusion of caste enumeration for the first time since 1931 [1][2][3].
VP C. P. Radhakrishnan (15th Vice President) submitted his self-enumeration form online at Uprashtrapati Bhavan on 01 April 2026, symbolically promoting public participation [4].

5. Multi-Dimensional Analysis
Administrative/Governance: First fully digital enumeration; data captured on mobile apps by enumerators; reduces lag between collection and tabulation [2].
Social: Caste enumeration revives statistical visibility of OBCs/sub-castes — last attempted in 1931; SECC-2011 caste data was never fully released. Implications for reservation policy and welfare targeting [3].
Legal/Constitutional: Conducted under Census Act, 1948; data confidentiality protected under Section 15 of the Act (treated as confidential, not admissible as evidence).
Scientific/Technological: Use of encrypted servers, mobile apps, GIS, and self-enumeration aligns with Digital India mission [2].
Federalism: HLO window of 30 days chosen at the convenience of State/UT Governments; cooperative federal exercise [3].
6. Recent Developments (last 12-18 months)

GS-II: Governance — "Government policies and interventions"; statutory bodies (RGI); federalism in census operations.
GS-I: Society — population, caste, urbanisation data implications.
Plausible question stems:
1. "Discuss how digitisation of Census 2027 will transform population data governance in India. What privacy concerns arise?"
2. "The inclusion of caste enumeration in Census 2027 is a watershed moment. Examine its implications for affirmative action policy."
3. "Evaluate the role of the Registrar General of India and the legal framework governing census operations."
