The has officially commenced the first phase of Census 2027—the houselisting and housing census—starting with the NDMC and Delhi Cantonment areas. This marks a historic transition as the decadal exercise is being conducted digitally for the first time using a dedicated mobile application and a Self-Enumeration portal.

UPSC Perspectives
Polity (Constitutional & Legal Framework)
The Census is a massive demographic exercise governed strictly by the constitutional framework under . It is exclusively a Union subject, explicitly mentioned in Entry 69 of the in the Seventh Schedule, which gives Parliament exclusive power to legislate on it. The statutory backing is provided by the , which makes it a binding duty for citizens to provide accurate information to enumerators. However, the Act simultaneously guarantees strict confidentiality; individual data collected cannot be made public or used as evidence in any court of law. The entire operation is spearheaded by the functioning under the .
Governance (Digital Innovation and Policy Targeting)
For the first time since modern censuses began in 1881, the exercise is transitioning from paper-based manuals to a fully digital format using the 'Census 2027-HLO' mobile application. The two-phase structure begins with houselisting, which collects micro-level data on 33 parameters including drinking water sources, cooking fuels, structural materials, and asset ownership. This specific dataset is critical for the government to evaluate the baseline penetration of welfare initiatives and target future beneficiaries. The introduction of a Self-Enumeration web portal also represents a major governance reform, reducing bureaucratic friction and the massive logistical burden on ground staff. Real-time digital data collection will eliminate the historical multi-year lag in publishing census abstracts, allowing policymakers to utilize the socio-economic data almost immediately for planning.
Political (Delimitation and Electoral Representation)
The demographic data collected in Census 2027 will have profound implications for India's electoral and political landscape over the next decade. Under the 84th Constitutional Amendment Act, the freezing of Lok Sabha and State Assembly constituencies is set to expire after the publication of the first census post-2026. Therefore, Census 2027 will form the foundational dataset for the next to redraw electoral boundaries and reallocate seats across states based on current population metrics. Furthermore, the implementation of the landmark , which grants 33% reservation to women in legislative bodies, is legally contingent upon the completion of this specific census and the subsequent delimitation exercise. This makes Census 2027 not just a statistical survey, but a catalyst for major democratic restructuring.
