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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The majority of Nebraska's zip codes report U.S. citizenship rates above 95% among the adult population, with nearly universal citizenship across the rural western and central portions of the state. Notable low-citizenship clusters — dropping to 75% or below — appear in south-central Nebraska (likely the Lexington and Grand Island areas), the Omaha metro area in the eastern edge, and a pocket around the South Sioux City area in the northeast, all regions with established meatpacking and agricultural processing industries that attract immigrant labor. The western panhandle also shows a modest band of lower citizenship rates, particularly along the Scottsbluff corridor, contrasting with the uniformly high rates in the surrounding Sandhills region.
