Census 2027, 80% Houses Mapped in New Delhi District as First Phase Nears Completion
With less than a week left for the completion of the first phase of Census 2027 in New Delhi district, enumerators have surveyed nearly 60,000 households through the House Listing Operations (HLO) mobile application and mapped around 80 per cent of Census houses ahead of the May 15 deadline, according to official progress data accessed by The Hindu. The house listing and housing census exercise began on April 16 across areas under the New Delhi Municipal Council (NDMC) and Delhi Cantonment jurisdictions. It involves physical mapping and geotagging of structures, followed by a door-to-door survey conducted by enumerators.
The district has been divided into 586 House Listing Blocks (HLBs), each assigned to an enumerator and estimated to cover around 180-200 houses and a population of 600-800 people. Enumerators collect responses to 33 questions through the HLO application. These include details related to construction material used in houses, sources of drinking water, cooking fuel, Internet connectivity, household composition, and household amenities, among others. The information is then verified by supervisors before being uploaded to the Census Management and Monitoring System (CMMS) portal. While enumeration data for nearly 60,000 households have been uploaded through the HLO application, supervisor verification has been completed for 55,202 households.
The Census of India is the largest administrative and statistical exercise in the world. It provides the foundational data for governance, policy-making, and resource allocation. The 2027 Census is particularly significant because it is the first digital Census, the first to allow self-enumeration, and the first to enumerate caste since 1931. The successful completion of the first phase in New Delhi district is therefore a critical milestone.
When the exercise started, 571 HLBs were identified. However, as the door-to-door exercise progressed, more houses were identified and marked. According to the May 8 progress report, 96,550 Census houses have been marked by enumerators in New Delhi district. Of these, around 77,000 houses, nearly 80 per cent, have been mapped so far. The mapping process involves not just counting houses but also geotagging each structure. This creates a digital map of the district that can be used for future planning and emergency response.
Delhi Cantonment recorded the highest proportion of pending mapping work with over 70 per cent of mapping still to be completed. The reasons for the delay are not specified in the report, but areas under Cantonment jurisdiction often have unique challenges, including the presence of military and civilian populations, restricted access, and older housing stock that may be harder to categorize.
For locked houses, enumerators make three visits before marking them absent, as per the rules. This is a sensible precaution. A house may be locked because the occupants are at work, on vacation, or have moved. Three visits, at different times of the day and on different days, increase the chances of finding someone at home. If after three visits the house is still locked, it is marked absent and the enumerator moves on. This data is not discarded; it is used to estimate the number of vacant or seasonal dwellings.
The overall exercise remains on track and is expected to be completed within the deadline, said New Delhi district Census officer Kapil Chaudhary. This is a testament to the hard work of the enumerators and supervisors, who have been working long hours in challenging conditions. The first phase of the Census is physically demanding. Enumerators walk from house to house, carrying mobile devices, and must convince residents to answer 33 questions. The data they collect is the raw material of the Census. If it is inaccurate, the entire exercise is compromised.
The data collected in the first phase serves multiple purposes. The housing data is used to update the National Population Register (NPR). The household data is used to create the frame for the second phase, the population enumeration, which will be conducted in February 2027. The housing data also provides insights into living conditions, access to amenities, and the quality of housing stock. This information is used by urban planners, policymakers, and researchers.
The digital nature of Census 2027 is a major departure from previous Censuses. In the past, enumerators used paper forms, which were then transported to data entry centres, keyed in, and processed. The process took years. The new digital system, using the HLO application and the CMMS portal, allows for real-time data entry and verification. Supervisors can check the data as it is uploaded, identify errors, and send back corrections. This should significantly reduce the time between data collection and data release.
The self-enumeration option, which allows residents to fill in their own data online, is not yet available for New Delhi district. Self-enumeration was offered in a limited number of areas in the first phase and will be expanded in subsequent phases. The self-enumeration portal, available in 16 languages, allows residents to fill in their data at their convenience, reducing the burden on enumerators and increasing accuracy.
The success of the first phase in New Delhi district is a positive sign, but the challenges are immense. India has over 1.4 billion people. The Census will cover every village, town, and city. The digital infrastructure must be robust enough to handle the load. The enumerators must be trained to use the technology. The public must be willing to participate. The Census is a massive exercise in trust. The government is asking citizens to share personal information. In return, the government promises confidentiality and the use of the data for public good.
The New Delhi district numbers are encouraging. But the real test will come in rural areas, where connectivity is poor, where literacy rates are lower, and where the enumerators face greater challenges. The Census is not just a technical exercise; it is a social one. It requires the cooperation of every citizen. The first phase is a dress rehearsal. The main event is yet to come.
