About these numbers
The FCC counts units, not buildings: an apartment or condo building is one location in its data, and each of its units is counted. Each share is of the units where providers reported residential service at that speed or faster, by the most they advertise; none of it is a measured speed. Wired means copper (DSL and similar), cable and fiber, and any non-satellite service is the FCC's Any Terrestrial group, wired and fixed wireless together. The FCC's files don't define some of their own terms: how the FCC draws rural, what its lowest speed tier (this page's "any speed") covers beyond its name, how a provider's share of a county's units is counted, and whether licensed-by-rule fixed wireless sits with the licensed or the unlicensed group. The rule that chose the counties is under How the counties were chosen, and the FCC's map is the place to check one address.
