The Census 2027 will keep the same definition of an urban area as used in Census 2011 to ensure consistent comparison of urbanisation trends.
An urban unit or ‘census town’ is defined as
A village with a minimum population of 5,000
A population density of 400 persons per square kilometre, and
At least 75% of the male working population is engaged in non-agricultural work.
In 2011, India had 15,870 urban units and towns, with 31.2% of the population living in urban areas, while 68.8% lived in rural areas.
The total number of villages in 2011 was 640,867, with the urban population rising from 17.3% in 1951 to 31.2% in 2011.
The Registrar General of India instructed states to prepare updated lists of villages and towns reflecting jurisdictional changes up to December 31, 2025.
Statutory towns will be counted as they exist on January 1, 2026.
The date when administrative boundaries will be frozen before Census operations begin on April 1, 2026.
Villages with populations of 4,000 or more in 2011 will be examined to identify those likely to have reached 5,000 by 2027.
Male workers engaged in agriculture, plantations, livestock, forestry, fishing, hunting, and related activities are excluded from the non-agricultural category.
District or sub-division headquarters will be classified as census towns only if they meet the demographic criteria and are not statutory towns.
Grouping of multiple villages as a single census town is disallowed; each village will be treated as a separate unit.
The Census 2027 will begin with house listing and housing census from April 2026, and the population enumeration phase in February 2027.
Administrative boundaries must be finalised by December 31, 2025, to be used in the Census process.
