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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the urban core of Dallas and immediately surrounding areas—particularly near Irving, Arlington, and parts of Fort Worth—exhibit the lowest U.S. citizenship rates among adults, frequently falling below 80%, reflecting concentrations of non-citizen immigrant populations. In stark contrast, the northern suburbs including McKinney, Plano, and the far northeastern and northwestern peripheral zip codes consistently register citizenship rates above 95%, forming a clear gradient from lower rates in the central metro to higher rates at the suburban fringe. The southeastern edge of the metro also shows pockets of lower citizenship rates, though less uniformly than the central Dallas cluster.
