Census 2027: Digital Data Collection and House Listing to Begin April 2026

Registrar General and Census Commissioner of India, Mritunjay Kumar Narayan, has officially announced the comprehensive roadmap for the upcoming Census 2027. During a press conference, it was confirmed that the national exercise will be conducted through digital mediums, marking a significant shift from traditional paper-based methods, while this will be the 16th national census of India and the 8th since independence. The government has reached an advanced stage of preparation, with administrative frameworks being mobilized across all states and union territories.

Timeline and Phases of the 2027 Census

According to the Registrar General, the gazette notification for Census 2027 was issued on June 16, 2025. The exercise is structured into two distinct phases. The first phase, encompassing 'Houselisting and Housing Census,' is scheduled to take place between April 2026 and September 2026. The notification for the duration of this first phase was released on January 07, 2026. While the questions for the first phase have already been notified, the schedule and specific queries for the second phase, which includes population enumeration and caste data collection, will be announced at a later date.

Key Questions for House Listing and Housing Census

The government has notified 34 specific questions to be asked during the first phase of the census starting April 01, 2026. These questions focus on the structural aspects of housing and the availability of basic amenities, while enumerators will collect data on the materials used for floors, walls, and roofs, the number of married couples residing in a household, and the gender of the head of the family. On top of that, information regarding access to modern necessities, types of vehicles owned, and the primary cereals consumed by the household will be recorded to create a detailed socio-economic profile of the population.

Digital Infrastructure and Self-Enumeration Portal

A major highlight of Census 2027 is the introduction of the self-enumeration option. Citizens will be able to fill in their details personally through a dedicated web portal. This portal will be operational for both the Houselisting and Population Enumeration phases. To facilitate this massive digital undertaking, the government has sanctioned a budget exceeding ₹11,000 crore. A specialized census application has been developed in 16 languages, while training manuals for officials have been prepared in 19 languages. District-level officers have already been appointed to oversee the ground-level execution of the digital data collection.

Caste Census and Data Confidentiality Protocols

The Registrar General confirmed that the caste-based enumeration will be integrated into the second phase of the census. Addressing concerns regarding data security, officials stated that the census data is strictly confidential and is legally protected from disclosure under the Right to Information (RTI) Act. The state government machinery, under the guidance of the Union Home Ministry, will execute the field operations. Instructions have been issued to the Chief Secretaries of all states to ensure the integrity and privacy of the collected data throughout the administrative chain.

Social Definitions and Enumeration Criteria

The government has also provided clarifications on social definitions through a set of Frequently Asked Questions (FAQs) on the self-enumeration portal. Notably, for the purpose of the census, couples in live-in relationships will be treated as married couples if they consider themselves as such permanently. This inclusive approach aims to reflect contemporary social realities accurately. The first phase will initially cover eleven states, including Kerala, Tamil Nadu, and Tripura, before expanding nationwide. The data collected will serve as the foundational basis for future government planning and resource allocation.
