Map boundaries
GeoJSON boundaries for US states, counties and 119th Congress congressional districts (Census 2025 cartographic boundary files at 1:20m and 1:5m) and world countries (Natural Earth 1:110m and 1:50m). Every feature's id is the location id the rest of the family uses (us-ca, us-county-06037, usa), so a map joins to any dataset by id. index.json lists every layer with its source, vintage and caveats.
