Census 2027: 40 Questions and 25 Minutes a Household — How Enumerators Are Being Trained

Field trainers across the country are preparing enumerators for the most demanding stage of India's census, with door-to-door enumeration for the second phase due to begin in four States on December 1, ahead of the rest of the country.

Uttar Pradesh, Uttarakhand, Goa and Punjab will start the Population Enumeration first. The exercise is scheduled to begin in the rest of the country in January 2027. All four States are due to go to the polls in the coming months, and the advance schedule allows the count to be completed before the election process begins.

The two phases of the census differ sharply in scale. Houselisting Operations, the first phase, took only a few minutes with each household. The Population Enumeration will put 40 questions to respondents and require enumerators to spend at least 20 to 25 minutes at every home.

The reason is straightforward. The houselisting schedule records the house and its amenities; the enumeration schedule records every person in the household, one line at a time, covering a wide range of particulars. Each answer has to be entered in the correct format, and an error recorded in the field is difficult to correct afterwards.

That is where the training comes in. Field trainers are working to ensure that enumerators know the questionnaire thoroughly, understand how each question is to be asked and recorded, and can handle practical difficulties — locked houses, absent members, reluctant respondents and questions that people may be hesitant to answer.

Because each household takes 20 to 25 minutes, an enumerator can cover only a limited number of homes in a working day. Supervisors will have to plan routes and arrange return visits where nobody was available, which is one reason the exercise runs over several weeks rather than a few days.

The questionnaire itself has been revised for 2027. The Union government has announced that the exercise will include enumeration by caste, a departure from the 2011 Census. Enumerators are being briefed on how such questions are to be put and recorded so that responses remain consistent across States and districts.

The census is a statutory exercise carried out under the Census Act, 1948, and individual returns are confidential. The data are used for delimitation of constituencies, allocation of resources and the planning of welfare schemes, and they form the base for a large share of the country's official statistics.

The 2027 count is also expected to be India's first digital census, with responses recorded on mobile applications and a facility for self-enumeration. For enumerators, that means additional training on devices and software on top of the longer questionnaire.

For households in the four States, the practical difference will be visible at the doorstep: visits will take considerably longer than during houselisting, and details will be sought for every member of the household. Enumerators are expected to carry identity cards, and residents can ask to see them before sharing information.

With the count due to be completed in the four States before the rest of the country follows in January, the coming weeks will test both the training modules and the enumerators who have to put them into practice.
