CHENNAI, JULY 31
Tamil Nadu is preparing for a month-long data march from doorstep to doorstep, with 1.15 lakh enumerators set to fan out across the State from August 1 to build the housing and household foundation for Census 2027. From urban neighbourhoods to rural habitations, the Houselisting and Housing Census will cover every household, generating crucial data on housing conditions, basic amenities and access to essential utilities.
- Door-to-door Houselisting and Housing Census begins across Tamil Nadu on August 1, covering every household till August 30
- Around 1.15 lakh enumerators and 19,000 supervisors to map housing conditions, amenities and utility access across the State
- 33-question digital schedule to capture vital data as India undertakes its first fully digital Census
- More than 10 lakh Tamil Nadu households already complete Self-Enumeration through the official online facility
- Residents urged to keep Self-Enumeration IDs ready and extend full cooperation to visiting Census personnel
The field operation will continue till August 30, 2026, with approximately 1.15 lakh enumerators, supported by around 19,000 Supervisors, covering 1.2 lakh House Listing Blocks across 1,026 administrative charges.
For residents, the exercise will mean a familiar Census experience—an official at the doorstep—but with a significant technological change behind the scenes: the questionnaire will be captured digitally through a dedicated mobile application, making Census 2027 India’s first fully digital Census.
Every doorstep counts
The Houselisting and Housing Census will use a structured 33-question questionnaire to collect information relating to housing conditions, basic amenities and utility access.
The exercise is designed to create the foundational statistical framework required for strategic planning, targeted welfare schemes, evidence-based policymaking and long-term development at different administrative levels.
With field personnel visiting households across the State, residents are urged to provide complete and accurate information and extend their cooperation to Census staff.
Digital census, door-to-door reach
While the Census embraces digital technology, its reach remains firmly rooted in the traditional door-to-door approach.
Enumerators will use a dedicated mobile application to digitally record information during household visits. The digital system is expected to enable faster processing, improve accuracy and make the overall Census operation more seamless.
The combination of technology and physical verification at the household level is intended to ensure comprehensive coverage while reducing delays associated with conventional paper-based data collection.
10 lakh+ households already self-enumerated
Tamil Nadu has already witnessed an encouraging response to the newly introduced Self-Enumeration (SE) facility for Census 2027.
More than 10 lakh households in the State successfully submitted their details online through the official Self-Enumeration portal between July 17 and July 31, 2026.
Residents who have completed Self-Enumeration have been requested to keep their generated Self-Enumeration ID (SE ID) readily available and share it with the visiting Enumerator during the Houselisting Operation (HLO).
However, completing Self-Enumeration does not mean that the household will be excluded from the field exercise. All households, including those that did not use the Self-Enumeration facility, will be covered during the Houselisting and Housing Census.
Confidential data, public purpose
The Census authorities have underlined the legal safeguards surrounding the information collected from households.
In accordance with the Census Act, 1948, information collected during the Census is legally protected and kept confidential. The data is to be used exclusively for statistical analysis and public policy formulation.
The digital collection and processing of Census data will also comply with provisions of the Digital Personal Data Protection (DPDP) Act, providing an additional legal framework for handling digitally collected information.
A statistical foundation for tomorrow’s Tamil Nadu
The Houselisting and Housing Census represents the foundational phase of the larger Census exercise. The information generated will help build a statistical base for understanding how people live, the amenities available to households and the infrastructure gaps that require policy attention.
Its eventual value will extend well beyond numbers on a Census database—from planning public services and welfare programmes to targeting development interventions and shaping long-term policy.
With more than a lakh enumerators preparing to go from home to home, the message from the Census authorities is straightforward: every household matters, every response counts and every doorstep is part of the State’s development map.
All residents of Tamil Nadu have been urged to extend full cooperation to the field staff and contribute to the successful conduct of Census 2027, one of the country’s most important national statistical exercises.
