CASTE BASED CENSUS
1. At a Glance
- Caste enumeration is the systematic recording of every individual's caste/jati during the decadal Census, abandoned for the general population after 1931 and revived for Census 2027 [S2][S3].
- Conducted by the Office of the Registrar General and Census Commissioner of India (ORGI) under the Ministry of Home Affairs, governed by the Census Act, 1948 [S1][S5].
- Critical for UPSC: intersects reservation policy, social justice (Arts. 15(4), 16(4), 340), federalism, and data-driven welfare targeting.
2. Why in the News
- PIB release dated 04 February 2026 confirmed that caste will be enumerated in the second phase (Population Enumeration) of Census 2027 [S1].
- Phase-one (HLO) questions were notified on 22 January 2026; caste-related questions for phase two will be notified before PE begins [S1].
- Cabinet Committee on Political Affairs (CCPA) chaired by PM Modi decided on 30 April 2025 to include caste enumeration in Census 2027 — first since Independence [S2][S3].
3. Background & Evolution
- 1881: First synchronous Census of India; caste recorded routinely thereafter [S2].
- 1931: Last comprehensive caste enumeration of all castes (under Census Commissioner J.H. Hutton) [S2].
- 1941: Caste data collected but not published (WWII) [S2].
- 1951 onwards: Independent India dropped full caste enumeration; only SC/ST counted [S2].
- 2011: Socio-Economic and Caste Census (SECC) conducted separately by Ministry of Rural Development & MoHUA — caste data never released due to classification issues [S3].
- 30 April 2025: CCPA approves caste enumeration in Census 2027 [S2].
- 16 June 2025: MHA issues formal Census 2027 notification [S4].
- 22 January 2026: Phase-one questions notified [S1].
4. Core Static Facts
- Nodal Ministry: Ministry of Home Affairs (MHA) [S1].
- Implementing Body: Office of the Registrar General and Census Commissioner of India (ORGI) [S4].
- Legal Basis: Census Act, 1948; Census Rules, 1990 [S5].
- Constitutional anchor: Union List, Entry 69 (Schedule VII) — Census is a Union subject.
- Reference Date: 00:00 hours of 1 March 2027 (1 October 2026 for snow-bound regions of J&K, Ladakh, Himachal, Uttarakhand — standard practice) [S4].
- Phases:
- Phase I — House Listing Operation (HLO): April–September 2026 — housing, assets, amenities [S1][S3].
- Phase II — Population Enumeration (PE): February 2027 — demographic, socio-economic, cultural, caste [S1][S3].
- First digital Census: data captured electronically via mobile app with self-enumeration option [S5].
5. Multi-Dimensional Analysis
Social - Provides empirical basis for revisiting the 50% reservation ceiling (Indra Sawhney, 1992) and sub-classification of SCs (Davinder Singh, 2024) [S2]. - Enables identification of dominant vs. marginalised OBC sub-groups; supports Rohini Commission (constituted 2017) on OBC sub-categorisation.
Legal / Constitutional - Reinforces Article 340 (Commission for backward classes) and Article 342A (Centre-State list of SEBCs, 102nd CAA 2018, restored by 105th CAA 2021). - Subject competency: Census is Union; but states (Bihar 2023, Karnataka, Telangana) had conducted parallel surveys, raising federal-comity questions.
Administrative - Integrating caste into the main Census (vs. separate SECC model) avoids the classification failure of SECC 2011 where ~46 lakh caste names were reported [S3]. - Digital enumeration shortens processing time but raises data-security concerns under DPDP Act, 2023.
Ethical / Governance - Tension between evidence-based welfare and risk of caste consolidation/political mobilisation. - Transparency demand: release of raw caste tables vs. aggregated data.
Economic - Inputs into targeted welfare (PM-KISAN, PMAY, scholarships) and labour-market diagnostics. - Likely budgetary expansion of OBC-linked schemes post data release.

- CCPA (not Union Cabinet alone) approved caste enumeration on 30 April 2025 [S2].
- Census 2027 reference date: 1 March 2027 (1 Oct 2026 for snow-bound areas) [S4].
- HLO = Phase I (housing/assets); PE = Phase II (persons + caste) [S1].
- Phase-I questionnaire notified on 22 January 2026 [S1].
- SECC 2011 was conducted by MoRD + MoHUA, NOT under Census Act, 1948 [S3].

- Bihar conducted a state-level caste survey in 2023 before Centre's decision [S2].
8. Mains Relevance
- GS-I: Indian Society — caste, social structure, social empowerment.
- GS-II: Governance (welfare targeting), Constitutional provisions for SCs/STs/OBCs (Arts. 340, 341, 342, 342A), federalism (Centre-State data competence).
- Probable stems: 1. "Enumeration of caste in Census 2027 is a step towards evidence-based social justice but risks deepening identity politics. Discuss." (GS-I/II) 2. "Compare SECC 2011 with the proposed caste enumeration in Census 2027. What lessons in classification and data management can be drawn?" (GS-II) 3. "Examine the constitutional and federal dimensions of conducting a caste census in India." (GS-II)

10. Common Errors / Trap Areas
- Wrong nodal body: ORGI/MHA conducts Census — NOT MoSPI (which runs NSSO/sample surveys).
- SECC ≠ Census: SECC 2011 was administered by MoRD/MoHUA, not under the Census Act, 1948.
- Last caste census year: 1931 (full); 1941 collected but unpublished — aspirants often write 1941.
- Approval body: It was the CCPA, not the full Union Cabinet, that cleared caste enumeration on 30 April 2025.
- Phase confusion: Caste is in Phase II (PE), not Phase I (HLO).
- Reference date for Census 2027 is 1 March 2027, not 1 January.
