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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Most Massachusetts zip codes exhibit high school graduation rates above 90%, with particularly strong concentrations across Cape Cod, the western suburbs of Boston, and much of western Massachusetts appearing in bright yellow tones indicating rates near or above 95%. Notable pockets of lower attainment—dropping into the 70-80% range—cluster in urban cores including parts of the Greater Boston area, Springfield in the southwest, and select communities in southeastern Massachusetts near New Bedford and Fall River. The sharpest contrasts occur in the Boston metro region, where adjacent zip codes can differ by 15-20 percentage points, reflecting stark educational disparities across short geographic distances.
