Ex-officials say Census data must be confidential amid concerns over potential NPR, NRC links

The recent concerns raised by former Census officials about the confidentiality of Census data and its potential linkage with the National Population Register (NPR) and National Register of Citizens (NRC) have reignited a critical debate on data privacy, citizenship verification, and the historical use of demographic data in India. To understand the gravity of this issue, we must first delve into the historical context. The 1951 Census of independent India was a monumental exercise, and records now reveal that the first National Register of Citizens (NRC) was prepared across the entire country by 'copying' data directly from the Census schedules. This is a startling historical fact because it establishes a direct, procedural precedent where Census data — collected under the promise of confidentiality for statistical purposes — was repurposed for a citizenship registry. However, this countrywide 1951 NRC was never published, except in the state of undivided Assam, which at that time comprised present-day Assam, Manipur, and Tripura. The Assam NRC of 1951 remains a unique historical document, later becoming the basis for the updated NRC in Assam published in 2019 under the Supreme Court's monitoring. The key stakeholders in this debate are multifaceted. At the forefront are the former Census Commissioners and senior officials who understand the sanctity of the Census Act, 1948. They argue that the Census relies entirely on public trust; citizens provide sensitive demographic, social, and economic information only because they are legally guaranteed under Section 15 of the Census Act, 1948, that this data will not be used for any purpose other than statistical analysis, and that individual records are not accessible even to courts of law. The government, on the other hand, views the NPR — a register of usual residents of the country — as a necessary administrative tool for better targeting of welfare schemes and national security. The NPR was first prepared in 2010 and updated in 2015, and its linkage with the Census 2021 house-listing phase (now delayed) has been a major point of contention. Civil society groups, opposition parties, and minority communities fear that the NPR is a precursor to a nationwide NRC, which could disenfranchise genuine citizens, particularly the poor and marginalized who lack documentary proof of lineage. The significance for India is profound across political, social, and governance dimensions. Politically, the NPR-NRC-Census triad has become a polarizing issue, influencing electoral narratives and federal relations, with several states like West Bengal, Kerala, and Punjab refusing to cooperate with the NPR update. Socially, it strikes at the core of citizenship rights and the fear of statelessness, reminiscent of the Assam experience where over 19 lakh people were excluded from the final NRC in 2019. Economically, a nationwide NRC would be an enormous fiscal and administrative burden. Constitutionally, the issue touches upon Article 21 (Right to Life and Personal Liberty, encompassing privacy as per the Puttaswamy judgment, 2017), Article 14 (Equality before law), and the Citizenship Act, 1955, particularly Section 14A inserted in 2004 which provides for compulsory registration of citizens and issue of national identity cards. The Census Act, 1948, and the Collection of Statistics Act, 2008, provide the legal framework for data collection and confidentiality. Broader themes of governance highlight the tension between state capacity for surveillance and citizen rights. The Digital Personal Data Protection Act, 2023, adds a new layer, mandating consent and purpose limitation for personal data processing, though state functions have certain exemptions. Internationally, India's commitment to the Sustainable Development Goals (SDGs), particularly Goal 16.9 (legal identity for all), must be balanced with human rights standards. Future implications are significant: the delayed Census 2021 (now likely post-2024) must navigate this trust deficit. If the government proceeds with linking NPR to Census without robust legal safeguards and public assurance, it risks compromising the integrity of the Census — the bedrock of policy planning, resource allocation (Finance Commission devolution), and delimitation of constituencies (Article 82). A possible way forward is a clear legislative separation: amending the Census Act to explicitly prohibit data sharing with NPR/NRC, or conducting the NPR under a separate, transparent legal framework with strict purpose limitation, ensuring the Census remains a purely statistical exercise as envisioned by the Constitution's framers.
