A subscription describes use, not an address-level offering

Census households report whether they have internet subscriptions in source-defined categories. FCC availability data describes what providers report offering at locations. A household can live where service is available without subscribing; a household using a cellular data plan may meet the ACS broadband definition without a fixed wired service. The measures are related but cannot substitute for each other.

Cellular inclusion changes everyday interpretations

Readers often interpret “broadband household” as a home with a cable or fiber connection. That is narrower than the approved ACS measure here. The table labels subscriptions rather than wired connections and keeps the original B28002 definition. It does not promise a minimum speed, a fixed line, unlimited data or simultaneous access for every member of the household.

The numerator and denominator are households

The national subscription share is 91.0%. Its denominator is households, not residents, devices, businesses or serviceable addresses. Multiplying the percentage by the annual population estimate would not produce the number of subscribers. The count in the comparison table comes directly from the appropriate household source cells, preserving the household universe.
