Most Iowa zip codes exhibit high school graduation rates between 85% and 100%, with the highest concentrations of yellow (95%+) areas spread broadly across the rural northern and central portions of the state. Notable pockets of lower attainment (teal and darker green, below 80%) appear in the northwest around the Sioux City–Storm Lake corridor, scattered central Iowa urban zip codes, and a distinct cluster in the southeast corner near the Missouri border, likely reflecting communities with larger immigrant populations or persistent poverty. A single zip code in the far southeast displays a strikingly low rate near 0–50%, representing a clear outlier against the otherwise high statewide educational attainment baseline.
