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

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across Oklahoma zip codes generally range from 75% to 95%, with notable pockets of lower attainment concentrated in the southeastern corner of the state and parts of the Oklahoma City metro core, where some zip codes dip below 60%. The northwestern panhandle region and several rural areas in western Oklahoma also display comparatively lower rates, appearing in darker teal shades, likely reflecting communities with higher immigrant or Native American populations. Suburban zip codes ringing Oklahoma City and Tulsa consistently show the highest graduation rates at 90–100%, forming bright yellow clusters that contrast sharply with their adjacent urban cores.
