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 [2][3].
• 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 [1][5].
• 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 [1].
• Phase-one (HLO) questions were notified on 22 January 2026; caste-related questions for phase two will be notified before PE begins [1].
• 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 [2][3].

3. Background & Evolution

• 1881: First synchronous Census of India; caste recorded routinely thereafter [2].
• 1931: Last comprehensive caste enumeration of all castes (under Census Commissioner J.H. Hutton) [2].
• 1941: Caste data collected but not published (WWII) [2].
• 1951 onwards: Independent India dropped full caste enumeration; only SC/ST counted [2].
• 2011: Socio-Economic and Caste Census (SECC) conducted separately by Ministry of Rural Development & MoHUA — caste data never released due to classification issues [3].
• 30 April 2025: CCPA approves caste enumeration in Census 2027 [2].
• 16 June 2025: MHA issues formal Census 2027 notification [4].
• 22 January 2026: Phase-one questions notified [1].

4. Core Static Facts

• Nodal Ministry: Ministry of Home Affairs (MHA) [1].
• Implementing Body: Office of the Registrar General and Census Commissioner of India (ORGI) [4].
• Legal Basis: Census Act, 1948; Census Rules, 1990 [5].
• 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) [4].
• Phases:
• Phase I — House Listing Operation (HLO): April–September 2026 — housing, assets, amenities [1][3].

• Phase II — Population Enumeration (PE): February 2027 — demographic, socio-economic, cultural, caste [1][3].

• First digital Census: data captured electronically via mobile app with self-enumeration option [5].

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) [2].
• 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 [3].
• 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.

6. Recent Developments (last 12-18 months)

• 30 April 2025: CCPA approves caste enumeration in Census 2027 [2].
• 04 June 2025: PIB release reiterates two-phase structure with caste in PE [3].
• 16 June 2025: MHA notifies conduct of Census 2027 [4].
• 22 January 2026: Phase-one questions notified [1].
• 04 February 2026: MHA reply via PIB confirms caste questions to be notified before PE [1].
• April 2026: PIB document positions Census 2027 as India's first digital enumeration [5].

7. Prelims Hooks

• Last full caste enumeration in pre-independence India: Census 1931 [2].
• Census conducted under Census Act, 1948 — a Union subject (Entry 69, List I) [5].
• Implementing agency: ORGI under MHA (not MoSPI) [1].
• CCPA (not Union Cabinet alone) approved caste enumeration on 30 April 2025 [2].
• Census 2027 reference date: 1 March 2027 (1 Oct 2026 for snow-bound areas) [4].
• HLO = Phase I (housing/assets); PE = Phase II (persons + caste) [1].
• Phase-I questionnaire notified on 22 January 2026 [1].
• SECC 2011 was conducted by MoRD + MoHUA, NOT under Census Act, 1948 [3].
• Census 2027 is India's first digital Census with self-enumeration option [5].
• Bihar conducted a state-level caste survey in 2023 before Centre's decision [2].

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.
