The FCC has published a Report and Order that makes significant changes to the way it collects data concerning broadband in the United States. At present, ISPs report the number of broadband subscribers based on ZIP codes; from now on, however, they have to report those numbers base on census track. In addition, ISPs have to break down the number of subscribers based upon broadband speeds: 200 Kbps to 768 Kbps; 768 Kbps to 1.5 Mbps; 1.5 Mbps to 3 Mbps; and so on. ISPs also have to report upload and download speeds. Unfortunately the FCC still defines broadband as 200 Kbps.
