How will caste be recorded in second phase of Census 2027? | Explained

The notification of 40 questions for the second phase of Census 2027 by the Registrar General and Census Commissioner of India (RG&CCI) marks a watershed moment in India's statistical and governance history. For the first time since 1931 — a staggering 96-year gap — the Indian Census will enumerate caste data, fulfilling a decades-long demand from social justice advocates, policymakers, and political parties. The last comprehensive caste enumeration was conducted under British rule in 1931; post-independence, only Scheduled Castes (SCs) and Scheduled Tribes (STs) were counted, while Other Backward Classes (OBCs) remained statistically invisible. This omission created a critical data vacuum, forcing reliance on outdated 1931 figures or sample surveys like the National Sample Survey (NSS) and Socio-Economic and Caste Census (SECC) 2011, which had methodological limitations and was never fully published. The 13 new data fields introduced in Census 2027 — beyond the 27 carried forward from 2011 — reflect a deliberate expansion to capture nuanced socio-economic realities. While the exact list is operational, they likely include sub-caste identification, educational attainment by caste, occupational categories, asset ownership, and digital access — all cross-tabulated with caste. This granularity is essential for evidence-based policymaking under Article 340 (appointment of Commission to investigate conditions of backward classes) and Article 15(4) (special provisions for socially and educationally backward classes). The data will directly impact the implementation of the 27% OBC reservation in central government jobs and education (mandated by the 93rd Amendment, 2005), the creamy layer exclusion criteria, and the rationalization of state-specific OBC lists. Key stakeholders include the Ministry of Home Affairs (nodal for Census), the National Commission for Backward Classes (NCBC), state governments (which maintain their own OBC lists), and political parties — particularly those championing social justice like the DMK, RJD, SP, and BSP. The demand gained momentum after the Mandal Commission (1980) recommended 27% OBC reservation based on 1931 data, and intensified with the 2011 SECC and the 2023 Bihar caste survey, which revealed OBCs/EBCs constitute over 63% of the state's population. The Census 2027 data will provide a nationally representative, legally robust baseline, potentially triggering a re-evaluation of the 50% reservation ceiling (Indra Sawhney v. Union of India, 1992) and fueling demands for a caste census at the national level — a promise made by several parties in the 2024 general elections. Constitutionally, this aligns with Directive Principles under Article 38 (minimizing inequalities) and Article 46 (promoting educational and economic interests of weaker sections). It also intersects with the 103rd Constitutional Amendment (2019) providing 10% EWS quota, as caste-income cross-tabulation will test its targeting efficiency. Internationally, India's move contrasts with countries like the US and Brazil that collect race/ethnicity data regularly; India's delay was an outlier among major democracies. Future implications are profound: the data may catalyze a new Mandal-style political realignment, prompt judicial scrutiny of reservation ceilings, and enable precision targeting of schemes like PM-Awas, Ujjwala, and Ayushman Bharat. However, challenges remain — ensuring enumerator training, preventing caste inflation, protecting privacy under the Digital Personal Data Protection Act, 2023, and managing political misuse. For aspirants, this is not just a Census update — it's a live case study in constitutional governance, social justice, and data-driven democracy.
