How we rank broadband coverage

Broadband coverage is the share of households with an internet subscription beyond dial-up, including cable, fiber, DSL, satellite, or cellular data.

It measures subscriptions, not available speeds or providers: a ZIP with fast service available can still rank lower if fewer households subscribe.

Only ZIPs with at least 1,000 residents are ranked, so a handful of households cannot top the list. 254 Connecticut ZIPs qualify.
