Fixed Broadband Concentration

Track national fixed-broadband HHI and median state, county, and census-tract HHI across FCC reporting periods. These geographic summaries describe different distributions, not one common market.

Interpretation boundary

A geographic screen, not a legal market finding

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.

Method and custody

Internet Access Services: Status as of December 31 2024

FCC Figure 5 reports provider-share HHI at the national level and the median of separately calculated state, county, and census-tract HHIs. Areas without at least one qualifying connection are excluded, and previously published values may have been revised.
