Methodology
To determine the most and least educated states in America, Writerbuddy compared the 50 states across various levels of educational attainment. The data was sourced from the American Community Survey by the United States Census Bureau, 2022 (the latest available). The study population comprised approximately 260,961,960 individuals aged 18 years or older.
We examined these dimensions using five relevant metrics, listed below with their corresponding weights. Each metric was graded on a 100-point scale, with a score of 100 representing the “most educated.”
We then determined each state’s weighted average across all metrics to calculate its overall score and used the resulting scores to rank the states.
Educational Attainment - Total Points: 100
- Share of Adults Aged 18 and Older with a Graduate or Professional Degree: Full Weight (~40 Points)
- Share of Adults Aged 18 and Older with a Bachelor's Degree or Higher: Full Weight (~35 Points)
- Share of Adults Aged 18 and Older with an Associate's Degree: Full Weight (~25 Points)
- Share of Adults Aged 18 and Older with a High School Diploma or Equivalent: Full Weight (~20 Points)
- Share of Adults Aged 18 and Older with Less than a High School Diploma: Full Negative Weight (~-20 Points)
