New Delhi, April 26: Prime Minister Narendra Modi on Sunday called upon every Indian citizen to actively participate in Census 2027, describing it not merely as a government exercise but as a collective national responsibility. Speaking during the 133rd episode of Mann Ki Baat, his monthly radio address, PM Modi underscored that this census is historic — marking India's first fully digital population census and the world's largest such exercise conducted entirely in digital format.

India's First Fully Digital Census: What's New This Time

Census 2027 introduces a landmark shift from paper-based data collection to a fully digital system. Enumerators visiting homes door-to-door are equipped with a mobile application that records information in real time, eliminating the need for physical forms and manual data entry.

"Those who have already undergone such a process will have a different experience this time," PM Modi noted, emphasising the technological leap this census represents over all previous editions. The digital infrastructure ensures faster, more accurate data compilation at a national scale.

This is the 16th decennial census in India's history and the 8th since Independence. Originally scheduled for 2021, it was postponed due to the COVID-19 pandemic — a delay of six years that makes the 2027 exercise even more consequential for policy planning across health, education, infrastructure, and welfare schemes.

Self-Enumeration: Citizens Can Now Enter Their Own Data

One of the most significant innovations in Census 2027 is the introduction of self-enumeration, a facility that empowers citizens to submit their own household data before the enumerator's visit. This window opens 15 days before the scheduled enumerator arrival in each area.

Upon completing the self-enumeration process, citizens receive a unique special ID on their registered mobile number or email address. When the enumerator subsequently visits, residents can simply show this ID to verify their pre-submitted data — eliminating the need to repeat the entire information-sharing process.

"This saves time and simplifies the process," PM Modi said, adding that the system has already shown results: house listing for approximately 1 crore 20 lakh families has been completed so far in states where self-enumeration is underway.

Historic Caste Enumeration After Nearly a Century

Beyond its digital character, Census 2027 carries profound political and social significance. For the first time since 1931 — nearly 94 years — the census will include comprehensive caste enumeration for all social groups, not just Scheduled Castes (SC) and Scheduled Tribes (ST).

This development is particularly significant given the sustained political pressure from opposition parties and Other Backward Classes (OBC) advocacy groups demanding a full caste census to inform reservation policies and welfare targeting. The inclusion of caste data for all groups could reshape affirmative action debates and electoral calculations across India's 28 states and 8 Union Territories.

Notably, the demand for a caste census had become a major political flashpoint, with the Congress party and regional outfits like RJD and SP making it a campaign centerpiece in recent elections. The government's decision to include it in Census 2027 represents a significant policy shift that addresses years of public demand.

Data Security and Citizen Participation: PM's Assurance

PM Modi directly addressed concerns around data privacy, assuring citizens that all information provided during the census is completely secure, kept confidential, and protected with digital security protocols. This assurance is critical to driving participation, particularly in an era of growing public awareness about data misuse.

"The national census isn't just a government task. It's the responsibility of all of us. Your participation is crucial," PM Modi said, urging citizens across the country to cooperate with enumerators and complete the self-enumeration process proactively.

Census data directly determines the allocation of central government funds, the drawing of parliamentary and assembly constituencies, and the targeting of flagship welfare programmes including PM Awas Yojana, National Food Security Act beneficiaries, and MGNREGS coverage. Inaccurate or incomplete census data has real consequences for millions of Indians who depend on government schemes for survival.

What Comes Next: Timeline and Broader Implications

With house listing already completed for over 1.2 crore families, the full population enumeration phase is expected to follow in a structured, state-by-state rollout. The Registrar General of India is overseeing the exercise, which will ultimately produce the most comprehensive demographic dataset India has generated since the pre-independence era.

The data from Census 2027 will also be critical for the delimitation of Lok Sabha and Vidhan Sabha constituencies — a process that has been constitutionally frozen since 1976 and is expected to resume based on the new census figures, potentially redrawing India's political map significantly.

As the census rolls out nationwide, citizens are encouraged to watch for official communications about self-enumeration windows in their area and to engage proactively with the process — a step that will shape India's governance, resource allocation, and democratic representation for the next decade.
