What market is this metric measuring?
Inspect each product boundary, geography, denominator, proxy choice, and permitted comparison use before treating concentration values as economic evidence.
Selected definition contract
U.S. residential fixed broadband access
Product boundary
Residential fixed internet connections with at least 100 Mbps downstream and 20 Mbps upstream
Geographic boundary
United States for the canonical market-profile series; separately calculated state, county, and census-tract HHIs are retained as geographic summaries
Measurement basis
FCC source-reported provider-share HHI for qualifying residential fixed connections
Denominator
Reported residential fixed connections meeting the 100/20 Mbps threshold in each FCC geographic calculation
Included
The annual December national HHI anchors and an exact route to the full four-scope semiannual FCC series
Excluded
Provider identities and shares, areas without a qualifying connection, slower service tiers, mobile broadband, enterprise service, and any claim that a geographic median is a legal market
Method and limitations
Publish only the December national HHI rows as market-profile anchors and preserve all four geographic summaries in the linked FCC resolution ladder.
The national HHI and medians of separately calculated state, county, and census-tract HHIs describe different geographic summaries. The source does not publish provider shares in this release, and none of these rows by itself establishes a legal product or geographic market.

Open data needs public interpretation.
The API is a starting point, not a legal conclusion. Pair downloads with methodology notes, source records, and the data-gaps report when citing market concentration.
