Map of AI data centers in the United States

There are 4,761 data centers on this map, identified one at a time from a primary source: the operator's own facility list, a county or state government inventory, or an open infrastructure register. With 150 more planned or under construction, that is 4,911 counted against an industry reference count of 4,767 for the United States.

The states with the most data centers are Virginia (825), California (482), Texas (446), Georgia (262), Illinois (212), Arizona (201), followed by Ohio (188), New York (134), New Jersey (121), Oregon (121). All 51 states with a data center have their own page here, listing every one of them by the city or county it stands in.

839 operators run them. The largest by building count are Lumen (200), Amazon Web Services (162), Digital Realty (104), QTS (104), Verizon Wireless (98), Equinix (92). 1,632 of the data centers publish a floor area and 990 publish a power figure, and a further 812 have a footprint measured from their mapped outline. Those figures are shown per facility rather than added together, because they are not the same measurement: one operator states the floor area of a building, another the full capacity of a campus it has only announced, and a mapped outline is a footprint rather than floor space.

Every data center here is joined to the five SAVRN trackers by its state and county, so the page can answer more than where the buildings are: which states and counties have paused new construction, what water rules apply, which grid operator the site connects to, which projects are delayed or blocked, and who has committed capital. That is 2,246 tracker records and 6,624 links between a data center and a record about the place it stands in.

Facility layer. Three open registers are pulled by script and merged into one database. Records from different sources within 250 meters that share a name or operator token are treated as one building; a Wikidata item within 400 meters of a placed facility is attached to it. Nothing is estimated to fill a gap: a facility with no coordinates in its source is placed at the centroid of other facilities in the same city and marked as city-level, and a facility whose typed state disagrees with its coordinates keeps the typed state and is re-placed the same way. Each point is assigned to a county with Census Bureau boundaries, which is the key the trackers join on.

Coverage and the target. The industry reference count for the United States is 4,767 facilities from 1,900 operators, and this map is built to reconcile to it. This build identifies 4,761 data centers, from 1,376 PeeringDB records, 1,791 OpenStreetMap features, 15 Wikidata items, and 3,965 buildings read from operator websites and government inventories. 4,621 of them are plotted; the other 140 publish no coordinates and appear in their state's table. With 150 planned or under-construction sites that is 4,911, or 103.0 percent of the target. The national totals now agree, but 26 states are still short by 470 between them while 25 run over by 615, so the reconciliation in "All the underlying data" below, not this percentage, is the measure of what is left. The directory's own listings are proprietary and its terms forbid copying them into another database, so nothing was taken from it; only its published per-state totals are used, as the ledger to reconcile against.

The listing threshold. The reference count lists a facility only at ten cabinets or more, so a building too small to hold that should not be counted. Every OpenStreetMap building was measured from its own outline, a median footprint of 120,066 square feet, and the unnamed ones below 200 square metres were dropped as below the threshold. Anything named or attributed to an operator is kept whatever its size, because the source vouches for it. Those measurements also give 1,632 facilities a published or measured floor area and 990 a published power figure.

Counting rule. The target counts unique facilities: every facility listing with no parent or sitting under a campus or multi-tenant building, with a campus of unknown building count counting once, a minimum of ten cabinets, and all four lifecycle stages included (land banked, planned, under construction, operating). This map is counted the same way, which is why planned and under-construction sites from the capital atlas and delay watchlist join the placed facilities in the comparison, and why a campus we can only place as one point counts once.

Tracker joins. State-level records join on the state. Local records are geocoded by county name first, then by city, using Census county boundaries, the placed facilities themselves, and the capital atlas place table; records that cannot be placed below the state are listed for the state but not drawn. Capital atlas sites carry coordinates and are linked to the nearest mapped facility within ten kilometers. Every record on this page keeps its source URL, and clicking a source opens it in a panel here rather than leaving the page.
