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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of Vermont zip codes report U.S. citizenship rates above 95% among the adult population, with rural areas across the state consistently at or near 100%. Notable exceptions cluster in the northwestern part of the state around the Burlington metropolitan area, where several zip codes dip into the 85–93% range, reflecting the region's concentration of immigrant and refugee communities. A few scattered zip codes in central Vermont, likely corresponding to college towns such as Middlebury and areas near Montpelier, also show modestly lower citizenship rates compared to the statewide norm.
