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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The south-central region of Washington, particularly zip codes in and around the Yakima Valley and lower Columbia Basin, exhibits notably lower high school graduation rates—many falling below 60%—likely reflecting areas with large agricultural workforces and immigrant communities. In contrast, suburban zip codes surrounding Seattle, particularly on the Eastside and in north Puget Sound communities, consistently register graduation rates above 95%. Rural eastern Washington displays considerable heterogeneity, with pockets of high attainment interspersed among moderate-performing areas, while the Olympic Peninsula and southwest Washington generally fall in the 80–90% range.
