Bachelor's Degree or Higher (% of Over 25) by Zip Code (ZCTA5) — Idaho

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Boise metropolitan area in southwestern Idaho exhibits the highest concentrations of bachelor's degree attainment, with several zip codes reaching 40–55%, while surrounding rural areas in the south-central and eastern portions of the state frequently fall below 15%. A secondary cluster of elevated educational attainment appears in the Sun Valley/Ketchum area of Blaine County and parts of the Moscow-Pullman corridor in the north, likely reflecting university presence and resort-community demographics. The most pronounced contrasts occur in the southeastern corner and portions of the Magic Valley, where adjacent zip codes can differ by 20+ percentage points, reflecting sharp urban-rural divides in educational composition.
