Legal / Constitutional - Census data triggers Article 82 (readjustment of Lok Sabha seats post-delimitation) and Article 170 (state legislative assemblies). [General] - Women's Reservation Act, 2023 (106th Amendment) operationalisation is contingent on first census post-enactment + delimitation. - Census is a Union subject — states cannot legally bar enumeration.

Technological - Mobile app in 16 languages; data captured on enumerator's own device; encrypted backend. [S3] - Linkage with NPR (National Population Register) — controversial; not yet confirmed for 2027.

10. Common Errors / Trap Areas

MHA, not MoSPI: Census is conducted by Office of RGI under MHA. MoSPI handles NSO/NSS.
Census Act 1948 vs Citizenship Act 1955: NPR is under Citizenship Act + Rules 2003, NOT Census Act.
Reference date confusion: 1 March 2027 (general) vs 1 October 2026 (snow-bound). Census year is 2027 even though Phase I happens in 2026.
SECC ≠ Census: SECC 2011 was a separate exercise; its caste data was never released. Census 2027 caste data is statutorily protected.
Caste enumeration: full caste data was collected last in 1931, not 1941 or 1951; only SC/ST has been continuously enumerated.
Census is a Union subject (Entry 69, Union List) — states cannot conduct their own constitutional census, though they may do surveys (e.g., Bihar Caste Survey 2023).
