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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Mississippi zip codes report U.S. citizenship rates above 95% among the adult population, with nearly uniform yellow shading across the state. Notable exceptions cluster around the Delta region in the west-central part of the state and scattered areas near Tupelo in the northeast, where several zip codes dip into the 85–93% range, likely reflecting concentrated immigrant labor communities tied to poultry processing and agriculture. A few zip codes in the central part of the state near the Jackson metropolitan area and along the Gulf Coast also display moderately lower citizenship rates, with at least one coastal zip code approaching the 75% threshold.
