Data: data/pmtiles/map/*.pmtiles (MapLibre vector tiles · PMTiles v3 · zoom 0–8, range requests on demand). If vector tiles are unavailable the page falls back automatically to data/web/global_adm{0,1,2}_<year>.geojson (WGS84 · EPSG:4326); the GeoJSON files are large, so the first load may take tens of seconds.

Click an administrative unit, then choose SHP, GPKG, SVG or GeoJSON to download it.
A official direct (green) · B official via aggregator (blue) · C OSM/third party (orange) · D derived (red). See the about page for what the grades mean.
ADM0 / ADM1 cover all four anchor years; ADM2 is available for the 2025 snapshot only (split into files by continent), so choosing another year automatically falls back to ADM1.
