Federal Communications CommissionInternet Access Services: Status as of December 31 2024

Scope: 9 periods across one national series and three subnational median series

The FCC series reports HHI for residential fixed connections of at least 100 Mbps downstream and 20 Mbps upstream. The national value and medians across states, counties, and census tracts describe different geographic summaries; they are not interchangeable legal market definitions, and a median does not describe the full distribution within or across areas.

Source custody

Recent source checks across the inventory.

Access dates document observatory custody. The source dossier records citation text, publisher, license posture, linked markets, and encoded uses.

Availability standard

Period, place, rows, and custody travel together.

This atlas inventories rows encoded in the current observatory release. A measurement year is not a source access date, an empty year cell does not establish that no underlying public data exists, and observed coverage does not imply a publisher schedule or forecast a future release.
