Population estimates (GRID3 v3.0)
Modelled gridded population raster (100m, GeoTIFF, Aug 2025) covering all of Nigeria, aggregatable to LGA/ward level.
An estimate, not a census, the last census was 2006 and the 2023 census did not happen.
States/LGAs JSON
Zero-dependency JavaScript package (naija-state-local-government) providing Nigerian states, LGAs and senatorial districts; some versions add wards and polling units.

v1.0 covers all states (approximate); high-accuracy v2.0 covers only 15 of 36 states.
