What Happened
- Union Home Minister Amit Shah completed the self-enumeration exercise for Census 2027 on April 1, 2026, becoming among the first senior government functionaries to participate in India's first-ever digital self-enumeration process.
- Shah used the online portal to submit his household's demographic data and urged all citizens to treat the self-enumeration as a "national duty" and cooperate with the census exercise.
- The Home Ministry, under whose jurisdiction the Office of the Registrar General and Census Commissioner of India (ORGI) falls, oversees the entire Census 2027 exercise.
- The self-enumeration phase runs from April 1–15, 2026, providing a 15-day window for citizens to voluntarily submit data online before enumerators conduct door-to-door surveys.
- The minister highlighted that this census — India's first fully digital census — will also capture caste data (including OBC) for the first time since Independence, marking a significant policy shift.
- The self-enumeration portal is available in 16 languages, and households receive a unique Self-Enumeration ID upon completion, which is verified during the subsequent enumerator visit.

Registrar General and Census Commissioner: Role and Mandate
The Office of the Registrar General and Census Commissioner of India (ORGI) is a statutory body under the Ministry of Home Affairs, responsible for conducting the decennial census and maintaining the Civil Registration System (CRS) — the system for registering births and deaths. The Registrar General also maintains the National Population Register (NPR).
- ORGI operates under the Census Act, 1948, which gives it authority to collect data on population, housing, and related socio-economic variables.
- The Census Commissioner is a senior IAS officer; the current role involves coordinating approximately 32 lakh field workers across India.
- The National Population Register (NPR) is a database of "usual residents" of India — distinct from the census but often conducted simultaneously during the house-listing phase.
- The NPR update was deferred alongside Census 2021; it is now expected to be updated during the Census 2027 house-listing phase (April–May 2026).
- ORGI also releases the Annual Health Survey, Sample Registration System (SRS), and linguistic data from census exercises.
Connection to this news: Amit Shah's public participation as Home Minister — the ministry that oversees ORGI — serves as both a political endorsement and a call-to-action for citizens to engage with the self-enumeration portal, critical for achieving high voluntary response rates in Phase I.
Digital Census: Technology and Data Governance
Census 2027 marks the transition from a paper-based to a fully mobile/digital data collection system. Enumerators will use dedicated Census Mobile Monitoring System (CMMS) app-enabled smartphones to collect data; citizens can pre-fill their data via the self-enumeration portal. This shift raises important data privacy and security questions — India now has the Digital Personal Data Protection Act, 2023, which governs how personal data may be collected and processed by the government.
- The Census Mobile Monitoring System (CMMS) enables real-time supervision of enumerator progress.
- The self-enumeration portal (available in 16 languages) is hosted on government servers; data submitted is encrypted and linked to the household's geo-coordinates.
- The Digital Personal Data Protection Act, 2023 (DPDPA) provides for certain exemptions for government processing of personal data for state functions — census data collection falls under this exemption framework.
- Census data is treated as confidential under Section 15 of the Census Act, 1948 — individual-level data cannot be disclosed for 15 years and is not shared with any government department for administrative use.
Connection to this news: The self-enumeration exercise is the public-facing entry point of India's first digital census — the minister's participation highlights the government's push to maximise digital engagement and achieve better data quality than the traditional door-to-door-only approach.
Caste Data and the OBC Question
The decision to enumerate caste in Census 2027 — specifically OBC data, which has never been counted in a decennial census — is politically transformative. The last caste-based census in India was conducted in 1931 by British India. The Socio-Economic Caste Census (SECC) of 2011 collected caste data but was never officially published in usable form due to data quality issues and political sensitivities.
- The Cabinet Committee on Political Affairs (CCPA) approved inclusion of caste enumeration in the Population Enumeration (PE) phase of Census 2027 in April 2025.
- The Mandal Commission (1980) estimated OBCs at 52% of India's population — but this figure has never been updated through an official census.
- The Supreme Court (in Pankaj Kumar Thakur v. State of Punjab, 2024) upheld sub-classification within SC reservations and suggested empirical data was necessary for equitable sub-classification — making census caste data legally significant.
- Six states (Bihar, Karnataka, Telangana, Odisha, Andhra Pradesh, Maharashtra) have conducted their own OBC surveys, providing a partial data picture ahead of Census 2027.
Connection to this news: Shah's emphasis on caste enumeration as part of the Census 2027 launch connects the administrative exercise to the BJP government's political commitment to OBC welfare and the broader demand for data-backed reservations policy.
