THE CONTEXT: Independent India has never counted every caste; the only nationwide head‑count was the 1931 British census. SCs and STs alone have been listed since 1951. On 30 April 2025 the Union Cabinet green‑lit adding “Other Backward Class (OBC)” details to the Census. Bihar’s 2023 caste survey revealed that OBC + EBC groups form 63 % of that state’s population, fuelling similar demands across India.
LEGAL FRAMEWORK FOR INCLUDING CASTE ENUMERATION IN THE CENSUS:
I. Statutory Authority: Census Act, 1948
-
- Registrar General’s Powers: Sections 3–8 of the Census Act, 1948 empower the Registrar General and Census Commissioner (RGI) to design the census schedule. This statutory authority allows the inclusion of additional questions, such as those pertaining to caste, without necessitating an amendment to the Act.
- Confidentiality Provisions: Section 15 of the Act ensures the confidentiality of census data, prohibiting its use as evidence in civil proceedings. This provision safeguards individual privacy and maintains the integrity of the data collected.
II. Constitutional and Institutional Mechanisms
-
- National Commission for Backward Classes (NCBC): Established under Article 338B of the Constitution, the NCBC is tasked with advising the government on the inclusion and exclusion of communities in the Central OBC list, which currently comprises approximately 2,650 communities.
- State vs. Central Lists: While the NCBC maintains a central list for OBCs, individual states have their own lists, leading to discrepancies and overlaps. The decision to use either or both lists for enumeration purposes has significant policy implications.
III. Judicial Precedents and Reservation Policies
-
- Indra Sawhney v. Union of India (1992): This landmark judgment upheld the 27% reservation for OBCs in central government jobs and introduced the concept of the ‘creamy layer’ to exclude the more affluent among OBCs from reservation benefits. It also established a 50% ceiling on total reservations, barring extraordinary circumstances.
- Jaishri Laxmanrao Patil v. Chief Minister, Maharashtra (2021): The Supreme Court struck down the Maharashtra government’s provision of 16% reservation for the Maratha community, reaffirming the 50% cap on reservations and emphasizing the need for quantifiable data to justify any breach of this limit.
IV. Privacy Considerations and Data Protection
-
- Justice K.S. Puttaswamy (Retd.) v. Union of India (2017): The Supreme Court recognized the right to privacy as a fundamental right under Article 21 of the Constitution. It laid down the principles of legality, necessity, and proportionality that any state action infringing on privacy must satisfy.
- Digital Personal Data Protection Act, 2023: Section 17 of this Act provides conditional exemptions for government operations like the Census, balancing the need for data collection with privacy concerns. However, it mandates that such data processing must be necessary and proportionate to the intended purpose.
V. Implications for Governance and Policy
-
- Data-Driven Policymaking: Accurate caste data can inform targeted welfare schemes and affirmative action policies, ensuring that benefits reach the intended beneficiaries.
- Reevaluation of Reservation Policies: The availability of updated caste data may prompt a reassessment of existing reservation policies, including the potential redefinition of the ‘creamy layer’ and adjustments to reservation percentages.
- Administrative Preparedness: Incorporating caste enumeration necessitates significant administrative efforts, including updating data collection tools, training enumerators, and conducting public awareness campaigns to ensure accurate and reliable data collection.
THE BIG CHOICE: WHICH OBC LIST?
1. Central list only (2,650 castes)
Pros: Uniform; matches Union‑level reservations.
Cons: Misses hundreds of castes recognised only by States—politically risky.
2. Merged central + state codes (could top 5,000)
Pros: Inclusive; respects federal diversity.
Cons: Technical overload; higher chance of spelling or code errors.
Policy dilemma: A purely technical exercise quickly turns political when it decides who counts.
HOW WILL THE EXERCISE ACTUALLY ROLL OUT?
| Step | Timeline* | What’s new this time |
|---|---|---|
| Gazette notifications (Centre → States) | ~2 months | Signals legal start. |
| e Schedule upgrade | +1 month | Drop down caste codes; Aadhaar tagged but privacy shielded. |
| Enumerator recruitment & digital training | +2 months | 25 lakh staff; focus on tablet use and misinformation drills. |
| Pilot survey / stress test | +1 month | Checks GPS, server load, caste spellings. |
| Full enumeration (House listing + Population) | 30–40 days on the ground | 100 % handheld devices; 20 % manual reserve. |
THE CHALLENGES:
I. Administrative Challenges
-
- Complexity in OBC Classification: With over 2,650 communities listed under the Central OBC category and additional communities recognized at the state level, there is a significant risk of code-swapping errors during data entry. Dr. Vivek Joshi, former Registrar General of India, has cautioned against “taxonomy overload,” emphasizing the need for a streamlined classification system.
- Human Resource Constraints: The attrition of trained enumerators, especially after the postponement of the 2020 Census due to the COVID-19 pandemic, poses a challenge. Recruiting and adequately training new personnel is essential to maintain data collection standards.
II. Technological Challenges
-
- Infrastructure Limitations: The adoption of digital tools for data collection introduces concerns such as tablet malfunctions and GPS inaccuracies, particularly in remote and hilly regions like the Northeast.
- Cybersecurity Threats: The increasing reliance on digital platforms makes the Census vulnerable to cyber-attacks. The Indian Computer Emergency Response Team (CERT-In) has issued advisories highlighting the risks of ransomware attacks on e-governance systems, underscoring the need for robust cybersecurity measures.
III. Legal Challenges
-
- Privacy Concerns: The collection of sensitive personal data raises questions about privacy rights, as established in the Supreme Court’s judgment in Justice K.S. Puttaswamy v. Union of India (2017), which recognized the right to privacy as a fundamental right under Article 21 of the Constitution.
- Data Protection Regulations: While the Digital Personal Data Protection Act, 2023, provides certain exemptions for government operations like the Census, it also mandates adherence to principles of necessity and proportionality in data processing. Balancing data collection needs with privacy protections is a critical legal consideration.
IV. Political Challenges
-
- Reservation Policy Debates: The publication of updated caste data may reignite debates over reservation policies, including demands to exceed the 50% reservation cap reaffirmed by the Supreme Court in Jaishri Laxmanrao Patil v. Chief Minister, Maharashtra (2021).
- OBC Sub-Categorization: The Justice Rohini Commission’s report on the sub-categorization of OBCs, submitted in July 2023, highlights disparities in the distribution of reservation benefits. Implementing its recommendations could lead to political contention among various OBC sub-groups.
V. Social Challenges
-
- Misinformation and Public Trust: The spread of misinformation, particularly through social media platforms like WhatsApp, can lead to public distrust in the Census process. Instances of enumerators being labeled as “data thieves” have been reported, emphasizing the need for effective public awareness campaigns to build trust and ensure cooperation.
