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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of non-citizen adult populations cluster along the southern border region and within the Phoenix metropolitan core, where several zip codes fall below 80% U.S. citizenship among adults. Rural and tribal areas across northern and eastern Arizona consistently report near-100% citizenship rates, creating a stark contrast with the urban and border corridors. The Tucson metro area displays a notably heterogeneous pattern, with adjacent zip codes ranging from under 75% to above 95%, likely reflecting neighborhood-level variation in immigrant settlement patterns.
