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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The overwhelming majority of West Virginia zip codes report U.S. citizenship rates at or near 100% among the adult population, reflected in the dominant yellow shading across the state. A few scattered zip codes—most notably in the eastern panhandle near the Virginia border and in the southern coalfield region—display slightly lower citizenship percentages in the 90–95% range, likely corresponding to areas with small immigrant or non-citizen worker populations. Gray-shaded zones, representing missing data, appear sporadically throughout the state and may correspond to sparsely populated or institutional zip codes with insufficient sample sizes.
