- Two phases:
- Phase I – House Listing & Housing Census (HLO): April–September 2026 (30-day window per State/UT, preceded by 15 days of self-enumeration) [S2].

5. Multi-Dimensional Analysis
Administrative / Governance - First census using mobile apps for enumerators with paperless data capture [S2][S4]. - Self-enumeration reduces enumerator load, enables real-time validation [S4]. - States/UTs choose the 30-day window per local convenience — cooperative federalism in scheduling [S2].
Social - Caste enumeration after nearly a century (last full caste census 1931); will feed reservation-policy debates [S4]. - Will update SC/ST/religion data, gender ratio, literacy — basis for delimitation post-2026.
Legal / Constitutional - Backed by Census Act, 1948 (Union List Entry 69 of 7th Schedule) [statutory]. - Article 82: readjustment of Lok Sabha seats after each census (frozen till first census after 2026 per 84th Amendment, 2001) — Census 2027 unlocks delimitation.
Scientific / Technological - Mobile-app based data capture; CMMS dashboards; web portal authentication via mobile OTP [S4]. - Data-security concerns: storage of PII of ~1.4 billion citizens.
Economic - Critical input for NSS surveys, NFHS, finance commission devolution, welfare targeting (PDS, PMAY, MGNREGA).

8. Mains Relevance
- GS-I: Society — population, demography, caste.
- GS-II: Polity & Governance — Article 82, delimitation; statutory bodies (RGI); e-governance.
- GS-III: Science & Tech / Internal Security — digital data, data protection.
- Question stems: 1. "India's first digital census promises efficiency but raises data-security concerns." Discuss. 2. "Inclusion of caste enumeration in Census 2027 marks a paradigm shift in Indian demographic policy." Examine the implications. 3. "The census is more than a headcount; it is the foundation of evidence-based governance." Critically analyse in the context of Census 2027.

10. Common Errors / Trap Areas
- Wrong ministry: it's MHA (RGI), NOT MoSPI.
- Census 2021 did NOT happen — it was postponed; Census 2027 is the next.
- NPR ≠ Census — NPR is updated under Citizenship Rules, 2003; Census under Census Act, 1948.
- SECC 2011 ≠ Caste Census — SECC was conducted by MoRD/MoHUA, not RGI.
- Reference date is 1 March 2027 (not 1 January or 1 April).
- Self-enumeration is optional and prior to the 30-day field enumeration window — not a replacement.
