About this ranking

People aged 25 and over whose highest degree is a 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.

A subset of bachelors_degree_share, which also counts people whose highest degree is a bachelor's.

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.
