Reading this population figure
West Bengal has a projected population of 10,05,22,000 for 1 March 2026 in the government’s 2011–2036 series. This is a modelled figure published in July 2020, not a new enumeration or a live count.
Its projection ranks 4 among the 36 current state/UT units in this collection. Its share of the published national projection is 7.05%, calculated from the source values.
West Bengal’s projected total reaches 100,522,000 in 2026, passing 100 million within this series. The date and July 2020 publication identify the particular projection behind that threshold.
99.88% reported penetration; 10,03,99,328 estimated living holders. UIDAI uses recorded addresses and an estimated-deaths adjustment, with its own projection denominator.

Define the people or households relevant to the product before estimating demand. A population total does not establish category adoption, purchasing power or the area that a business can actually serve.
For West Bengal, keep the projection’s date in your working sheet, document the eligible share and spending assumptions, and test how the answer changes. For a local outlet, define a city, district or travel-time catchment instead of using the whole state or union territory.
