The methodology behind every numeric value on this page is publicly documented on the the FCC Broadband Data Collection (BDC) portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
