Bachelor's Degree or Higher (% of Over 25) by Zip Code (ZCTA5) — Boston Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The western and northwestern suburbs—including Newton, Waltham, and surrounding communities—consistently register bachelor's degree attainment rates above 50%, forming a broad band of highly educated zip codes across the metro's outer ring. In sharp contrast, several zip codes in Boston's southern neighborhoods (Dorchester, Mattapan, and Roxbury areas) and parts of Lynn display attainment rates below 20%, representing the metro area's most pronounced educational attainment gap within just a few miles. Quincy and Weymouth Town occupy a middle tier in the 30–40% range, serving as a transitional zone between the high-attainment western suburbs and the lower-attainment urban core and North Shore communities.
