Some states and cities have an abundance of prestigious schools and universities, while others rely on a smaller number of large public institutions to educate their populations.
The importance given to a college degree also varies by state, region, and individual career path.
Business Insider analyzed the latest US Census Bureau data on the percentage of adults 25 and older in all 50 states who have earned a bachelor's degree or higher. We used that measure to rank the states by educational attainment for this list.
Associate degrees were not included in each state's ranking, but Business Insider also reviewed those figures to highlight where two-year credentials are more common, helping show how residents in different states may prioritize different levels of education.
In some cases, states with low shares of bachelor's and graduate degree holders have higher rates of adults with associate degrees. The trend is also evident in the inverse: Some of the most educated states, in terms of bachelor's degrees or higher, also have some of the lowest rates of associate degree attainment.
