Map sources and method

The state outline is adapted from the U.S. Census Bureau 2025 cartographic boundary file. Facility coordinates are adapted from Compute Atlas by Edward Kubiak, edition 1.34.1, under CC BY 4.0. Outline and markers use one geographic projection before any explicitly disclosed readability offset. Exact singleton source anchors are never moved. A one-kilometre boundary tolerance prevents the simplified 1:20,000,000 outline from hiding legitimate border-area source points; farther conflicts are disclosed, not clamped. DataCenterData groups source-reported city coordinates only within a bounded map radius; the outline does not validate a facility record. Some locations in this layer are reported by the provider as derived from OpenStreetMap (© OpenStreetMap contributors, ODbL, https://www.openstreetmap.org/copyright) and Epoch AI (CC BY 4.0).

Two layers, two jobs. These licensed rows have not been independently verified by DataCenterData and are not a census. Reviewed evidence remains separate.

Separate layer

Also listed by operators

Sites that operators list on their own websites and that are not rows in the licensed directory above. They are kept apart and never added to the licensed rows.

Separate layer

Listed in the federal EPA registry

Street addresses where the U.S. EPA facility registry lists a registration whose name says data center or whose registrant is a known operator under industry code 518210, and that are not rows in the licensed directory or operator-listed sites. Each is one or more registry records, not a building count, and is never added to the counts above.

State and local registry records

Government records that name a data-center project or facility and are not already a licensed row, operator-listed site, federal registry address, or reviewed record. A permit or application is not an operating data center. These records are never added to the counts above.
