What Happened

  • The Registrar General of India (RGI) confirmed that preparations for Census 2027 are at an advanced stage, with caste enumeration to be conducted during the second phase (Population Enumeration in February 2027).
  • The Union Cabinet had cleared caste enumeration as part of Census 2027 on April 30, 2025 — the first time caste data will be mainstreamed into India's national Census since comprehensive caste enumeration was last conducted during British rule (1881–1931).
  • Phase 1 (Houselisting and Housing Census) begins April 1, 2026 and runs through September 2026; Phase 2 (Population Enumeration) takes place in February 2027 with a reference date of 00:00 hours on March 1, 2027.
  • The Union Budget allocated ₹6,000 crore for Census 2027; the RGI's total budget requirement is ₹14,618.95 crore.
  • Around 30 lakh field personnel will be deployed nationwide; self-enumeration via a web portal will be available in Hindi, English, and regional languages.

Static Topic Bridges

The Census is conducted under the Census Act, 1948, which gives the Central Government the power to take a census of population at such time as may be necessary. The Registrar General and Census Commissioner of India, under the Ministry of Home Affairs, is the nodal authority. "Census" is a Union subject under Entry 69 of the Union List (Seventh Schedule), meaning only Parliament can legislate on it. The decennial Census serves as the foundational data source for delimitation of constituencies, allocation of seats in Parliament and state legislatures, computation of grants-in-aid, and implementation of welfare schemes.

  • Census Act, 1948 — primary statute governing India's census operations.
  • Entry 69, Union List, Seventh Schedule — "Census" is exclusively a Central subject.
  • The Registrar General and Census Commissioner of India sits under the Ministry of Home Affairs.
  • Census data informs delimitation (under the Delimitation Act), MGNREGS targeting, SC/ST list notifications, and OBC identification.
  • India has conducted a decennial census since 1881; Census 2021 was delayed due to COVID-19, making Census 2027 the first in nearly 16 years.

Connection to this news: The delay since 2011 and the upcoming 2027 exercise have made this census uniquely consequential — it will provide the first updated socioeconomic and demographic baseline in over 15 years, with caste data now formally included.

Caste Enumeration: Historical Context and Policy Significance

Comprehensive caste enumeration was last conducted during British India between 1881 and 1931. After independence, independent India's Census counted only Scheduled Castes and Scheduled Tribes, not Other Backward Classes (OBCs). The Socio-Economic Caste Census (SECC) of 2011 collected some caste data but was not published in disaggregated form for OBCs. The Mandal Commission (1980) relied on 1931 caste data to estimate OBC population at 52% for reservation purposes. Inclusion of caste data in Census 2027 is expected to provide an empirically grounded basis for OBC reservation policies and potentially challenge or validate the creamy layer threshold.

  • Last full caste census in India: 1931 (British era).
  • Post-independence censuses: counted SC/ST populations only; OBC data not collected in Census.
  • SECC 2011: collected household-level socioeconomic and caste data but OBC caste-wise data not released publicly.
  • Mandal Commission (1980): estimated OBCs at 52% based on 1931 census data.
  • Supreme Court's 50% reservation cap (Indra Sawhney v. Union of India, 1992) will be reassessed in light of new caste data by several states.

Connection to this news: The RGI's confirmation that caste enumeration will happen during Phase 2 (Population Enumeration) clarifies the operational structure — caste data will be collected as part of the main population count, not as a separate exercise, giving it official Census status for the first time since independence.

Technological Transformation in Census 2027

Census 2027 will be India's first fully digital census, marking a fundamental departure from paper-based enumeration. Key innovations include smartphone-based data collection by enumerators, geo-tagging of households, real-time monitoring through the Census Management and Monitoring System (CMMS) portal, citizen self-enumeration via web portal, and expanded questions on migration, disability, and economic activity. This digital shift is expected to improve data quality, reduce turnaround time for data release, and enable real-time quality checks.

  • 30 lakh field personnel to be deployed across India.
  • One enumerator per 700-800 persons; one supervisor per 6 enumerators.
  • CMMS portal: tracks field appointments, enumeration blocks, supervisory circles in real time.
  • Self-enumeration portal: available in Hindi, English, and regional languages.
  • Phase 1 (Houselisting): 33 questions including number of married couples per household.
  • Snow-bound regions (Ladakh, J&K snow areas, Himachal Pradesh, Uttarakhand): both phases in September 2026; reference date October 1, 2026.

Connection to this news: The RGI's statement that preparations are at an advanced stage reflects the CMMS infrastructure being built and states already appointing enumerators — the digital-first approach requires substantial lead time for training and equipment.
