🇳🇬Verified Datasets in Nigeria

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.

Zero-dependency JavaScript package (naija-state-local-government) providing Nigerian states, LGAs and senatorial districts; some versions add wards and polling units.

Ward boundary polygons in GeoJSON/SHP, no auth.

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

Gridded population count raster for Nigeria at ~100m (3 arc-second) resolution, 2020, in GeoTIFF, UN-adjusted and constrained to building footprints. Single-file download ~58.67 MB from WorldPop (University of Southampton), CC BY 4.0.

Large Yoruba parallel speech-text corpus of 1,647,022 audio-text pairs (~21.5 GB, WAV) aligned with the MMS-300M Forced Aligner for ASR and TTS, with clips of 0.04-12 seconds.

[ingest-scout] Large-scale benchmark from McGill-NLP for evaluating large language models across African languages; covers diverse NLP tasks and language families. Active GitHub repository under the same McGill-NLP lab that produced AfriqueLLM. Complements IrokoBench (already in registry) but targets broader language coverage and LLM evaluation. Confirmed live on GitHub under McGill-NLP organisation.
