Coverage and limits

Of 2,241 tracked sites, 89% have coordinates, 64% name an operator and 5% carry a disclosed construction value. Coverage depends on what each jurisdiction publishes: states with open permit portals are represented far better than states without, so a low count means we have less evidence there, not necessarily fewer datacenters. We exclude 93 sites whose permits describe incidental IT work inside an existing building, and 1,139 records with no address or coordinates.

Frequently asked

How many data centers are there in the US?

We track 2,241 datacenter sites across 52 states, deduplicated from 5,810 building permits and public facility records. Published estimates range from roughly 1,400 to over 4,000 depending on whether colocation suites, carrier hotels and enterprise server rooms are counted as separate facilities. We count physical sites and exclude incidental IT rooms inside office buildings.

Which state has the most data centers?

Virginia leads with 588 tracked sites, followed by Texas (161), California (139), Illinois (102).

How many data centers are under construction in the US?

545 of the sites we track have permits indicating construction is under way, versus 1,322 operational. Because this is permit derived, it reflects filings with local authorities rather than announced intentions.

Where does this data come from?

City and county building permit portals, state and regional facility records, EPA air permits for backup generators, PeeringDB, and state utility commission large-load filings. Every figure on this site carries the number of records it is based on, and the whole dataset is free to download.
