% of Households with Broadband Internet, by Zip Code (ZCTA5) — Colorado

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Denver-Boulder metropolitan corridor and surrounding Front Range suburbs consistently exhibit broadband adoption rates above 90%, with many zip codes reaching 95–100%, reflecting dense urban infrastructure investment. In contrast, rural areas across the southern San Luis Valley, the southeastern plains, and parts of the Western Slope show markedly lower penetration, with several zip codes falling below 60–70%. Mountain resort communities such as those near Aspen, Vail, and Telluride appear as notable exceptions to the rural trend, maintaining relatively high broadband rates comparable to urban areas.
