374 Wikidata zoo points carve the US into nearest-zoo territories — three jurisdictions return none

Asked:
show me a voroni diagram mapping out all Nearest Zoo locations in the USA. go state-by-state then aggregate
Spelling corrected: Voronoi.

A Wikidata SPARQL query for zoo-classified facilities in the United States returned 382 geocoded rows (374 unique facilities after de-duplication), covering 48 states; Vermont, Wyoming and the District of Columbia returned zero. Extracted 2026-08-31. Each Voronoi cell is the region geographically nearest — straight-line, not driving distance — to that facility among this returned dataset only.

National Voronoi map — Wikidata zoo locations returned by query

Cells are colored by state (categorical, natural-history palette) and clipped to US land. Scroll or pinch to zoom, drag to pan. Alaska and Hawaii appear as insets; cells there are computed in the same projected space. Where Wikidata coverage is sparse, cells look very large — that reflects data coverage, not real travel.
California leads with 41 mapped facilities; Texas (24) and Florida (34) follow — the coasts dominate Wikidata's zoo coverage. query.wikidata.org
Vermont, Wyoming and the District of Columbia returned zero rows, so their residents' nearest cell belongs to a neighboring state's facility. query.wikidata.org
The zoo class in Wikidata pulls in aquarium-named facilities too — Aquarium of the Pacific and Birch Aquarium sit among the 374. wikidata.org
Coverage caveat: Wikipedia calls its US zoo list incomplete, OfficialUSA claims a directory spanning all 50 states, and AZA reported 240 accredited institutions as of September 2025 — different inclusion rules, so none of those counts should be blended with the 374 mapped here. en.wikipedia.org · officialusa.com

State by state — within-state cells, alphabetical

Each card recomputes Voronoi cells from that state's points only, clipped to its border. Zero-result jurisdictions are flagged, not omitted.

Every row derives from the same Wikidata SPARQL result; per-facility Wikidata links are in the map tooltips. Source: query.wikidata.org

Data: Wikidata SPARQL query for entities that are instance/subclass of zoo, country United States, with coordinates, resolved to a US state; 382 rows returned, 374 unique facilities after de-duplication by entity; extracted 2026-08-31. "Nearest" means straight-line geographic proximity between point coordinates within this returned set only — not driving distance, and not every zoo that exists. Wikidata classification may include aquarium-named facilities and omit or misplace others. Context sources (Wikipedia, OfficialUSA, AZA) use different inclusion rules and are not blended with these counts.
