About this ranking

People aged 25 and over whose highest degree is a bachelor's, master's, professional school or doctorate degree, as a percentage of all people aged 25 and over. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Excludes associate degrees and college without a degree. Not comparable with EU tertiary attainment, which includes short-cycle tertiary education and usually covers ages 25 to 64. Calculated from counts in ACS table B15003, which are stored as inputs.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
