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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Kansas zip codes report U.S. citizenship rates above 95% among adults, particularly across the central and eastern portions of the state, which appear uniformly in yellow. A notable cluster of lower citizenship rates—dropping to 75–85%—is concentrated in the southwest region, likely corresponding to meatpacking and agricultural communities in areas such as Finney, Ford, Seward, and Grant counties. Scattered pockets of moderately lower rates also appear in the Kansas City metro area along the eastern border and in a few central-south zip codes, suggesting localized immigrant populations in urban and industry-driven communities.
