Reading this population figure
Bihar has a projected population of 13,22,65,000 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 2 among the 36 current state/UT units in this collection. Its share of the published national projection is 9.28%, calculated from the source values.
Bihar’s 132,265,000 projection exceeds Maharashtra’s 129,308,000 in the same 2026 table, making Bihar the second-largest projected state in this series. This is a modelled ordering, not a newly enumerated ranking.
88.29% reported penetration; 11,67,82,847 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 Bihar, 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.

Resident population, migrants, commuters and tourist visits describe different populations or activities. Use migration evidence to examine usual residence; use tourism releases for visits. Neither should simply be added to this projected population.
