High School Graduate (% of Over 25) by Zip Code (ZCTA5) — Wisconsin

NOTE: Gray indicates insufficient data or a suppressed estimate.

Most Wisconsin zip codes report high school graduation rates above 85%, with particularly high rates (95–100%) concentrated in rural northern counties and suburban areas surrounding Madison and Milwaukee. Notable pockets of lower attainment—dropping below 70% in some cases—appear in urban cores, particularly in the Milwaukee metropolitan area in the southeast and several central Wisconsin zip codes likely corresponding to communities with larger immigrant or Native American populations. The contrast between high-performing suburban rings and adjacent urban centers is especially pronounced in the southeastern corner of the state, where yellow-shaded suburbs sit immediately adjacent to dark teal and blue urban zip codes.
