Census 2027: New Questions and Election Timing Raise Data Concerns

On August 14, 2026, the Registrar General and Census Commissioner announced that Uttarakhand and Goa will commence the SECC‑2011 based eligibility enumeration ahead of the national rollout, while deferring the exercise in conflict‑ridden Manipur. The early rollout tests the inclusion of newly added caste categories and 13 fresh questionnaire items, but critics warn it could miss millions of migrant workers who traditionally return after March. Analysts estimate that up to 2.5 million seasonal workers from Uttar Pradesh could be excluded from the eligibility list if the census is held before the usual March window.

•The Union government’s decision to advance the Population Enumeration phase of the 2027 Census in four poll-bound states—Uttar Pradesh, Punjab, Uttarakhand, and Goa—while introducing 13 new questions, including sensitive data on religion, Aadhaar numbers, and parental details, has reignited debates over data privacy, governance transparency, and the potential revival of the National Register of Citizens (NRC).
•The changes, announced by the Registrar General and Census Commissioner of India (RG&CCI) on August 14, 2026, coincide with Assembly elections in these states, raising concerns about under-enumeration of migrant workers and the long-term implications of collecting granular demographic data.
•A precedent for using Census data to prepare an NRC dates back to 1951, when the first Census in independent India enabled the creation of a nationwide register, though it was never published outside Assam.

The Union government’s decision to advance the Population Enumeration phase of the 2027 Census in four poll-bound states—Uttar Pradesh, Punjab, Uttarakhand, and Goa—while introducing 13 new questions, including sensitive data on religion, Aadhaar numbers, and parental details, has reignited debates over data privacy, governance transparency, and the potential revival of the National Register of Citizens (NRC).

A precedent for using Census data to prepare an NRC dates back to 1951, when the first Census in independent India enabled the creation of a nationwide register, though it was never published outside Assam.

What Happened with Census 2027?

The 2027 Census marks a significant departure from the 2011 questionnaire, with the RG&CCI adding questions on parents’ names, religion, place of birth, and identification documents like Aadhaar and voter IDs. These additions mirror the National Population Register (NPR) updation process conducted in 2019, which collected similar data under the Census (Amendment) Act 2011. The enumeration in four states has been moved to September 2026, ahead of the rest of India’s February 2027 phase, with a reference date of March 1, 2027. Notably, the Census will now enumerate caste data beyond Scheduled Castes and Scheduled Tribes for the first time in independent India.

▸Four states (Uttar Pradesh, Punjab, Uttarakhand, Goa) began enumeration in September 2026 due to election schedules.
▸13 new questions added, including religion, Aadhaar, and parental details, aligning with the 2019 NPR rehearsal form.
▸Caste enumeration expanded to include all communities, not just SC/ST categories.
▸Reference date set for March 1, 2027, with snow-bound areas enumerated earlier.

Historical Precedent: 1951 NRC and Census Data

The 1951 Census report by R.B. Vaghaiwalla, the Superintendent of Census Operations for Assam, Manipur, and Tripura, reveals that the NRC was initially conceived as a Census and administrative tool, not a citizenship-verification mechanism. Vaghaiwalla’s report notes that the register was intended to be maintained permanently and updated by village officials, ensuring continuity between Censuses. Despite Section 15 of the Census Act 1948, which mandates confidentiality of records, the 1951 NRC was prepared using Census data, establishing a legal precedent for repurposing demographic data. A former Census official, speaking anonymously, clarified that the NPR and Census are governed by distinct laws, and the 2019 Assam NRC update did not rely on NPR data, requiring a separate exercise.

▸1951 NRC was prepared by “copying” Census schedules, per Vaghaiwalla’s report.
▸Section 15 of the Census Act 1948 ensures confidentiality, yet the NRC precedent remains.
▸NPR and Census are legally separate, with the 2019 Assam NRC requiring independent data collection.

Legal and Ethical Concerns

The inclusion of sensitive data like religion and Aadhaar has sparked fears of misuse, particularly in light of the 2019 Assam NRC exercise, which excluded over 1.9 million individuals. Critics argue that the new questions could facilitate the creation of a nationwide NRC, a move opposed by civil society and political parties. The Puttaswamy Judgment (2017) established privacy as a fundamental right under Article 21, raising questions about the legality of collecting such data without explicit consent. Additionally, advancing the Census in election-bound states may lead to under-enumeration of migrant workers, as they return to their home states to vote, creating gaps in both locations.

▸Privacy concerns: The Puttaswamy Judgment mandates data protection under Article 21.
▸Migrant undercount: Election timing risks excluding workers who vote in home states.
▸NRC revival fears: Civil society opposes data collection linked to citizenship verification.

Implications for Governance and Social Justice
