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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Minnesota zip codes report U.S. citizenship rates above 95% among adults, with near-universal citizenship prevalent across the rural northern and western portions of the state. Notable concentrations of lower citizenship rates—dropping to 75% or below—cluster in the Twin Cities metropolitan area, particularly in Minneapolis zip codes, as well as in scattered pockets in southern Minnesota near Worthington and Marshall, likely reflecting immigrant and refugee communities in meatpacking regions. A few isolated zip codes in the northwest near Moorhead and the northeastern tip near the Canadian border also show moderately lower rates in the 85–90% range, contrasting sharply with surrounding areas at or near 100%.
