ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the western and northwestern portions of the metro area—particularly around Arvada, Lakewood, and Broomfield—consistently exhibit U.S. citizenship rates above 95% among the adult population, while a pronounced low-citizenship corridor extends from central Denver through Aurora, where several zip codes fall below 80%. The southern suburbs near Centennial display moderate variability, with pockets dipping into the 75–80% range adjacent to areas exceeding 90%, suggesting sharp demographic boundaries at the zip code level.
