The most and least educated US states, ranked by the share of adults with a bachelor's degree or higher

Big gap across states — Massachusetts leads with 48.3% of adults holding a bachelor's or higher, while West Virginia trails at 24.4%.
Some states favor two‑year degrees: North Dakota has the highest share of associate degrees (14.2%), and several places show high associate rates even when bachelor's attainment is low.
Local access to colleges and job markets matters — regions with many elite schools push graduate degrees, while others emphasize technical or trade education depending on local demand.
