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

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across Indiana zip codes generally fall in the 80–95% range, with suburban and rural areas in the northern and central parts of the state tending toward higher rates (yellow-green tones), while notable pockets of lower attainment (below 70%) appear in urban cores—particularly in the Indianapolis metropolitan area, Gary/Lake County in the northwest, and several zip codes in the south-central region near the Kentucky border. A distinct cluster of very low graduation rates is visible in the southwest-southern portion of the state, likely corresponding to areas with significant Amish or immigrant populations. The highest-performing zip codes, reaching near 100%, are scattered throughout suburban rings and smaller communities in the northeast and north-central regions.
