As of 2023, OPM collected availability data was submitted by internet service providers pursuant to PA 21-159 and processed by the GIS Office in the Office of Policy and Management, cleaned, and matched to the CostQuest location fabric.

Metadata:

All feature layers, maps, and datasets including OPM's internal broadband availability data follows the same basic schema with additional fields added in some case for convenience.

Fields named no service, unserved, underserved, served, and GigC are counts of locations where a particular level of broadband service is provided, No service locations are those where there is no reported service at all. Unserved locations are locations where there is a provider offering wireline service, but not at or above 25 Mbps download and 3 Mbps upload. Underserved locations are locations where at least one provider offers wireline service of 25 Mbps download and 3 Mbps upload, but there is no provider offering wireline service of 100 Mbps download and 20 Mbps upload. Served locations are locations where there is wireline service of at least 100 Mbps download and 20 Mbps upload. GigC denotes the count of locations that have service at 1000 Mbps download and 100 Mbps upload. Accordingly, total locations is equal to the sum of no service, unserved, underserved, served, and "GigC" locations. Availability also includes fields for average download and upload speeds. These are calculated at the relevant level of census geography based on the maximum for all locations.

The final field included in all availability data is the provider list.
