1. At a Glance

• Conducted by the Office of the Registrar General & Census Commissioner of India (ORGI) under the Ministry of Home Affairs through the Census Act, 1948. [1][4]
• Critical for UPSC: links demography, federalism (delimitation, women's reservation), social justice (caste data), and governance (digital public infrastructure).

2. Why in the News

• GS-II: Polity & Governance — welfare schemes targeting; delimitation (Art. 82, 170); 106th Amendment (women's reservation); federalism.
• GS-III: Indian Economy — data infrastructure; digital governance.
• Probable question stems: 1. "Census 2027 marks a paradigm shift in Indian statistical governance. Examine the constitutional, administrative and ethical implications of caste enumeration." (GS-II, 250 marks) 2. "Discuss how the delay in Census operations since 2021 has impacted welfare delivery and federal devolution in India." (GS-II) 3. "Evaluate the opportunities and risks of conducting India's first digital census." (GS-III)

9. Related Topics to Study Next

• Delimitation Commission & Article 82 — Census 2027 will trigger seat readjustment.
• Women's Reservation Act, 2023 (Nari Shakti Vandan Adhiniyam) — implementation tied to Census + delimitation.
• SECC 2011 vs Census — distinguish: SECC under MoRD/MoUD, not under Census Act.
• National Population Register (NPR) — administered under Citizenship Act, 1955; often confused with Census.
• Mandal Commission & OBC reservation — relevance of caste data.
• Finance Commission devolution formula — population (1971 vs 2011) weightage controversy.
• NSO / PLFS / NFHS — surveys that use Census as sampling frame.
• Aadhaar & Digital Public Infrastructure — comparator for digital data governance.

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).
