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

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across the Chicago metro area exhibit a stark urban-suburban divide, with outer suburban communities in DuPage, western Cook, and McHenry counties consistently exceeding 95%, while concentrated pockets of lower attainment (below 70%) cluster in Chicago's South and West Side neighborhoods—particularly around Englewood, Cicero, and Back of the Yards—as well as in Gary, Indiana. Northwestern suburbs such as Naperville, Schaumburg, and Palatine form a broad band of high attainment (90–100%), contrasting sharply with the deep teal and blue zip codes along the city's industrial corridors and south lakefront. A secondary cluster of lower graduation rates is visible around Elgin and parts of Aurora, likely reflecting immigrant-dense communities where educational attainment patterns differ from surrounding suburban areas.
