Sources & data note

All population, household, density, sex-ratio and growth figures are from the National Population and Housing Census 2021 (NSO National Report, Table 15; census reference date 25 November 2021), with 2011 comparisons from the 2011 census recalculated to current boundaries for the four districts split in 2017. Areas are the official statistical areas used by NSO/CBS, the 77 districts sum to exactly 147,181 km², not GIS polygon areas; where Wikipedia's list page prints conflicting areas for the four split districts (Nawalpur, Nawalparasi West, Rukum East, Rukum West), the NSO-consistent figures are used. Literacy rates are computed from NSO Table 24 raw counts (population aged 5+ who can read and write); the computed national aggregate, 76.25%, matches NSO's published 76.2%. Headquarters coordinates are approximate map-pin locations (±2–5 km), not surveyed points.
