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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Michigan zip codes report U.S. citizenship rates above 95% among the adult population, with near-universal citizenship across the Upper Peninsula and much of the northern Lower Peninsula. A notable concentration of lower citizenship rates—dropping to 75% or below—clusters in the southeastern corner of the state, particularly in the Detroit-Dearborn metropolitan area, where several zip codes display deep purple shading indicative of substantial non-citizen adult populations. Scattered pockets of moderately lower citizenship rates (85–90%) also appear in west-central Lower Michigan, likely corresponding to agricultural communities in the Grand Rapids and Holland areas with established immigrant populations.
