This boundary matters. Kolkata UA includes Kolkata corporation and places such as Haora (Howrah), Kalyani and Barasat. This grouping crosses district boundaries, so statistics for Kolkata corporation or Kolkata district need a geographic check before being compared with the UA.

Kolkata (M Corp.) has a separate Primary Census Abstract profile, including households, children, literacy, social categories and worker details. Its count is 4,496,694 people in 2011. Use its source-defined boundary; it is not a replacement for the urban unit displayed above.
The official Class I urban table records 1,40,57,991 people for Kolkata U.A. in 2011. It ranks 3 among the main urban agglomeration and standalone-city totals in that table. We keep the main total and do not add its constituent places again.
The source classifies this unit as urban agglomeration. The figure belongs to the 2011 boundary and reference year. It should not be relabelled as Kolkata’s population today.
Use this count to understand the scale of the historical urban unit. An outlet, delivery service or local campaign may serve only part of it. Define the catchment, eligible customers and buying unit before attaching a spending assumption.
A state’s 2026 projection does not provide a verified current projection for this city. Updating the city count requires a documented city-specific method or an applicable official release. Our calculator keeps the Census 2011 label when you select this city.
A resident population count does not measure the number of visitors, daily commuters or people present in a neighbourhood on a given day. Tourist visits can repeat, while migration statistics depend on a usual-residence definition and a reference period.
For Kolkata, begin with the geographic unit printed in the source. A statistic for the surrounding district, a metropolitan planning region or the whole state cannot be substituted without an explicit boundary comparison.
