## How to read this

- Area partitions are not additive: total already contains urban and rural, and tribal and nontribal. Exactly one partition is reported.
- Tier shares are cumulative, so they must not be added together.
- Availability is self-reported by providers and describes where service is or could be offered.
- Availability is self-reported by providers and describes where service is or could be offered, not subscriptions taken or speeds actually delivered.
- The Broadband Serviceable Location Fabric is licensed separately by CostQuest and is not redistributed here; no address or coordinate for any location identifier is published by this service.
- Reported figures are revised between publications, so a statement must cite the as-of date and the revision it came from.
