U.S. Citizens (% of Population Over 18) by Zip Code (ZCTA5) — Utah

NOTE: Gray indicates insufficient data or a suppressed estimate.

The majority of Utah's zip codes report U.S. citizenship rates above 95% among the adult population, with the highest concentrations of near-100% citizenship spanning the rural western and northern portions of the state. A distinct corridor of lower citizenship rates (75–85%) runs through the Wasatch Front urban core, particularly in zip codes around Salt Lake City, West Valley City, and portions of Utah County, likely reflecting higher concentrations of immigrant populations in these metro areas. Several isolated zip codes in southeastern Utah and near the Colorado Plateau also display notably lower citizenship percentages, possibly corresponding to tribal nation lands or smaller communities with distinct demographic profiles.
