State-led caste surveys are both a tool of social justice and a source of federal friction. Examine in light of recent initiatives by States such as Tamil Nadu.

The Union will count caste in Census 2027 [2]. Alongside it, Tamil Nadu's Cabinet has set up a commission headed by a retired High Court judge to hold a "Social Justice Survey" after the Census [1]. Such surveys give reservation policy the data it needs, but they also test the line between Union and State powers.

Caste surveys as a tool of social justice

• Courts now demand data: In 2022 the Supreme Court struck down TN's 10.5% Vanniyar internal quota. It found no substantial basis for treating Vanniyars differently from the other MBC communities [3]. The Maratha judgment (2021) requires quantifiable and contemporaneous data to go above 50% [4].
• Depth, not just a headcount: Telangana's survey recorded socio-economic, educational, employment, political and caste data. It put BCs at 56.36% of the population and backed Bills for 42% BC reservation [5].
• Fair sub-categorisation: Community-wise data can show which BC/MBC groups still lag and which ones take most of the quota benefits.
• Credibility: A panel headed by a retired judge gives independence to a sensitive exercise [1].

Caste surveys as a source of federal friction

• Legislative competence: Census is a Union subject (Entry 69, List I). So States call their exercise a "survey" and conduct it under their own powers.
• Union's objection: When it approved caste enumeration in the Census, the Centre argued that caste should be counted there instead of in separate surveys. Its reason was that some State surveys lacked transparency and created doubts in society [2].
• Two datasets: Census and State figures for the same caste may not match. Whoever loses a court case can then argue that the other dataset is the right one.
• The 50% ceiling: Under Indra Sawhney, the 50% cap stays. Telangana's 42% BC quota takes total reservation well past 50% [5]. State data alone cannot remove a limit set at the national level.
• Politicisation: TN's survey was a TVK manifesto promise [1], which invites the charge of vote-bank politics.

Way forward

• Frame the survey rules around the Court's tests: measure backwardness and share in public jobs for every community, side by side [3][4].
• Record religion along with caste, since the Supreme Court has just ruled on BC quota claims by converts [1].
• Publish the method and anonymised data, and agree common standards with the Census.

Used carefully, State caste surveys can turn the promise of Articles 15(4) and 16(4) into evidence-based policy. Under cooperative federalism, the Union Census can supply the headcount while State surveys add the socio-economic detail. Run on shared standards, the two can work together rather than clash, advancing substantive equality and SDG 10 (Reduced Inequalities).
