Q11 / Broadband geographies / Geographic structure

What provider-share, technology, speed-tier, entry, and geographic composition changes explain the rise in national HHI while median subnational HHIs declined?

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.

Observed signalUnited States moved from HHI 1,195 in Dec 2023 to 1,501 in Dec 2024 (+306 HHI points).

The December 2024 national hhi is higher 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.

Evidence to collect

4 declared requests
  1. 01

    Area-level provider connection shares behind the national or median geographic HHI path.

  2. 02

    Full state, county, or tract HHI distributions so movement in the median is not mistaken for a uniform shift.

  3. 03

    Technology, speed-tier, entry, exit, acquisition, and subscriber-mix records for both annual anchors.

  4. 04

    Local product, geographic, pricing, quality, switching, and availability evidence before treating a reporting area as an antitrust market.

These requests define collection work. Their inclusion does not assert that the records exist, support a claim, or establish a cause.
