High School Graduate (% of Over 25) by Zip Code (ZCTA5) — St. Louis Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across the St. Louis metro area exhibit a stark urban-suburban divide, with outer suburban zip codes in St. Peters, St. Charles, and the western and southern periphery consistently reaching 95–100%, while central St. Louis City zip codes drop sharply to 50–70%. A corridor of lower attainment extends northward from downtown through Florissant and the near north suburbs, suggesting persistent educational disparities aligned with historically segregated neighborhoods. The eastern portions of the metro on the Illinois side and the far northeast also display notably mixed outcomes, contrasting with the uniformly high rates in the western exurban ring.
