Most and Least Educated Counties in America

Falls Church city, Virginia, leads the nation with 79.7% of adults holding a bachelor's degree or higher. Among counties with more than 5,000 residents, McDowell County, West Virginia, is lowest at just 5.7%. That 74.0 percentage-point gap is one of the sharpest divides in U.S. demographic data, shaping median incomes, civic participation, and long-term economic trajectory county by county.

The Most Educated Counties in America

The highest bachelor's degree attainment rates cluster around federal research hubs, high-income suburban rings around large metros, and mountain resort towns. The median BA rate across counties with populations above 5,000 is 21.5%.

1. Falls Church city, Virginia: 79.7% with a bachelor's degree or higher
2. Arlington County, Virginia: 77.1% with a bachelor's degree or higher

The Least Educated Counties in America

At the other end, among counties with populations above 5,000, those with the lowest BA attainment rates tend to be rural, economically isolated, or historically underserved by higher education infrastructure. Many of these counties also post below-average high school graduation rates, indicating compounding barriers to educational access across the pipeline.

1. McDowell County, West Virginia: 5.7% with a bachelor's degree or higher
2. Kusilvak Census Area, Alaska: 5.8% with a bachelor's degree or higher
3. Elliott County, Kentucky: 6.2% with a bachelor's degree or higher

9. Lee County, Kentucky: 7.5% with a bachelor's degree or higher
10. Jenkins County, Georgia: 7.8% with a bachelor's degree or higher

High School Graduation: A Separate Divide

Bachelor's degree rates capture one layer of educational attainment, but high school completion tells a different story about foundational access. Among counties with populations above 5,000, the median share of adults with at least a high school diploma is 89.6%. The counties with the lowest rates:

1. Holmes County, Ohio: 57.1% high school graduate or higher
2. Gaines County, Texas: 58.3% high school graduate or higher
3. Starr County, Texas: 60.1% high school graduate or higher
4. LaGrange County, Indiana: 60.6% high school graduate or higher
5. Maricao Municipio, Puerto Rico: 60.6% high school graduate or higher
6. La Salle County, Texas: 63.9% high school graduate or higher
7. Zapata County, Texas: 64.1% high school graduate or higher
8. Wolfe County, Kentucky: 66.0% high school graduate or higher
9. Presidio County, Texas: 66.1% high school graduate or higher
10. Brooks County, Texas: 67.4% high school graduate or higher

Education and Income: What the Data Shows

Across U.S. counties, BA attainment and median household income move together closely. Falls Church city's 79.7% college attainment rate corresponds to a median household income of $154,734. Jenkins County's 7.8% rate corresponds to $36,906. The link is strong but is not proof of cause: across counties with more than 5,000 residents, bachelor's attainment alone accounts for a little under half of the county-to-county variation in median household income.

Why County-Level Data Matters

National averages for education mask the concentration of both attainment and under-attainment in specific places. College towns inflate state averages. Remote rural counties with limited access to two-year or four-year institutions depress them. Examining the county-level distribution reveals where education gaps are most acute, which communities are being left behind in the knowledge economy, and where targeted investment in community colleges, broadband access, and workforce training could have the greatest impact.
