The observation behind the question
December 2024 versus December 2023 in the same FCC geographic summary. The intervening June release remains visible in the broadband atlas and is not used as the annual comparison anchor.The December 2024 tract median is lower than its December 2023 anchor. This geographic summary does not define a legal broadband market or identify why provider shares changed.
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.Declared empirical track
Geographic structure
Reconcile national and nested geographic concentration summaries with area-level distributions, provider or ownership paths, measurement boundaries, and local-market evidence.- Evidence base

Evidence to collect
4 declared requests- 01
Area-level provider connection shares behind the national or median geographic HHI path.
- 02
Full state, county, or tract HHI distributions so movement in the median is not mistaken for a uniform shift.
- 03
Technology, speed-tier, entry, exit, acquisition, and subscriber-mix records for both annual anchors.
- 04
Local product, geographic, pricing, quality, switching, and availability evidence before treating a reporting area as an antitrust market.

Collection requests above remain separate from these published source records.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.
