About this ranking

People aged 25 and over who hold a regular high school diploma, a GED or alternative credential, or any higher level of education, 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.

Measures the adult population, not students: it is not the high school graduation rate of a class. Not comparable with the EU share below upper secondary education, which covers ages 25 to 64.

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.
