Conducted by the Office of the Registrar General & Census Commissioner of India (ORGI) under the Ministry of Home Affairs, governed by the Census Act, 1948 [S2][S5].

Socio-Economic Caste Census (SECC) 2011 — predecessor to caste enumeration debate.
Digital Personal Data Protection Act, 2023 — data security backdrop.
Article 82 & 170 — readjustment of seats post-Census.
Women's Reservation Act (Nari Shakti Vandan Adhiniyam, 2023) — operational only post-Census + delimitation.
MoSPI vs MHA distinction — NSO/NSS vs Census jurisdiction.

Ministry confusion: Census is under MHA, not MoSPI [S1][S2].
Caste enumeration ≠ SECC: Census 2027 caste data is collected under Census Act, unlike SECC 2011 under welfare ministries.
Reference date is not the field date — actual enumeration runs Feb 2027; reference is 1 March 2027 [S2].
Self-enumeration is optional and supplementary, not a replacement for enumerator visits [S1][S3].
Census is in the Union List (Entry 69) — not Concurrent.
The 1931 census counted all castes; 1941 caste data was not published, not "1941 had no caste data" [S3].
