CLAT GK + CONSTITUTIONAL LAW & DATA PRIVACY
India’s 16th census and first fully digital enumeration — Census 2027 — officially launched its Phase 1 self-enumeration on April 1, 2026, marking a historic departure from the traditional door-to-door format. For the first time in the history of the Indian census, citizens can fill in their own household data through a secure web-based portal at se.census.gov.in. The first batch of states and UTs — Andaman & Nicobar Islands, Delhi (NDMC and Delhi Cantonment Board), Goa, Karnataka, Lakshadweep, Mizoram, Odisha, and Sikkim — will conduct self-enumeration from April 1 to April 15, 2026, followed by house-to-house houselisting from April 16 to May 15. The Union Government has approved ₹11,718.24 crore for the exercise, which was last conducted in 2011 (the 2021 census was deferred due to COVID-19).
Census Act 1948: The foundational law governing the census in India. It defines the powers of census officers, the duty of citizens to respond truthfully, and penalties for providing false information or refusing to fill census schedules. Census data is confidential under the Act — it cannot be used for taxation or legal proceedings against individuals.
Article 246 & Union List Entry 69: Census is a Union subject under Entry 69 of the Seventh Schedule — meaning only Parliament has the legislative competence to make laws on census. This makes the Census Act 1948 and Census 2027 exclusively within the Union Government’s domain.
K.S. Puttaswamy v. Union of India (2017): A 9-judge Constitution bench unanimously held that the right to privacy is a fundamental right under Article 21. The judgment identified three key elements: bodily integrity, decisional autonomy, and informational privacy. The mass collection of digital census data directly implicates informational privacy rights.
Digital Personal Data Protection Act 2023 (DPDPA): India’s landmark data protection legislation governs the processing of digital personal data. The census’s digital self-enumeration portal raises important questions about data sovereignty, encryption standards, and the government’s obligations as a “data fiduciary.”
National Population Register (NPR): The NPR, which collects data on “usual residents,” is linked to the census process and serves as a precursor to the National Register of Citizens (NRC). The NPR-NRC link raises the stakes of accurate self-enumeration data significantly.
The Census 2027 is being conducted in two phases. Phase 1 — the House Listing and Housing Census (HLO) — runs from April to September 2026, giving each state/UT a 30-day window for house-to-house enumeration, preceded by a 15-day self-enumeration window. Phase 2 — Population Enumeration (PE) — is scheduled for February 2027 and will collect demographic, socio-economic, educational, and for the first time, caste data. The reference date for the census is March 1, 2027 (with October 1, 2026 for snow-bound regions like Ladakh, J&K, Himachal, and Uttarakhand). The Registrar General and Census Commissioner of India, Mritunjay Kumar Narayan, confirmed the portal supports 16 Indian languages including Hindi, English, Tamil, Telugu, Kannada, and Urdu.
The digital self-enumeration process works as follows: citizens access se.census.gov.in → log in using mobile number → identify location on map → fill household details → submit → receive a unique Self-Enumeration ID. This SE-ID is then verified when the enumerator visits for house-to-house listing. End-to-end data security with encryption and support from cybersecurity agencies has been promised. The scale is unprecedented: over 3 million enumerators, supervisors, and officials across 36 states/UTs, 7,092 sub-districts, 5,128 statutory towns, and approximately 6.4 lakh villages.
The census also marks the first time caste enumeration will be conducted alongside the regular population count — a politically significant decision that will provide data for OBC reservation policies under Article 15(4) and Article 16(4). The last caste census was conducted in 1931 during British India. This data will directly inform the Mandal Commission’s recommendations and the constitutional ceiling on reservations post-Indra Sawhney v. Union of India (1992).
Census 2027 is high-value CLAT territory. Test yourself on: (1) Union List Entry 69 — census as a Union subject under Article 246; (2) Census Act 1948 — citizen duties, confidentiality, penalties for false information; (3) Puttaswamy judgment (2017) — right to privacy under Article 21, three elements of privacy, implications for digital data collection; (4) DPDPA 2023 — India’s data protection law, data fiduciary obligations; (5) NPR vs NRC — distinction, constitutional basis, and controversy. A CLAT passage may present a scenario of a citizen refusing to fill the census and ask about legal consequences under the Census Act 1948, or present the digital portal’s data collection and ask about privacy implications under Article 21 and the Puttaswamy judgment.
| Fact | Detail |
| Census Number | 16th census of India; 8th post-Independence; first fully digital |
| Self-Enumeration Portal | se.census.gov.in — launched April 1, 2026 |
| Phase 1 (First Batch) | Self-Enum: April 1-15 | Houselisting: April 16 – May 15, 2026 |
| Phase 2 Reference Date | March 1, 2027 (Oct 1, 2026 for snow-bound regions) |
| Budget | ₹11,718.24 crore approved by Union Government |
| Legal Basis | Census Act 1948 | Art. 246 + Union List Entry 69 |
Mnemonic — “COUNT WITH PRIVACY”: Census Act 1948 = legal authority for census. Only Union can legislate on census (Entry 69, Union List). Union List + Article 246 = Parliament’s exclusive domain. NPR → NRC connection = high controversy. The Puttaswamy triad: Bodily integrity + Decisional autonomy + Informational privacy. Key fact: The last caste census was in 1931 (British India) — Census 2027 will be the first post-Independence caste count. DPDPA 2023 = India’s data protection law. False census info = punishable offence under Census Act 1948.
