About this ranking

Households with a broadband internet subscription of any type (cellular data plan, cable, fiber optic, DSL, satellite or other non-dial-up service), as a percentage of all households. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Counts a paid subscription, so households that only use free access (a library or public wifi) are not included. A cellular data plan alone counts as broadband. A separate series from households_internet_access_share, the Eurostat share of households with internet access at home.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
