In the 118th Congress, 94% of representatives and all but one senator hold at least a bachelor’s degree, according to an analysis of U.S. House and Senate data. The educational attainment of the current Congress far outpaces that of the overall U.S. population: In 2021, around four-in-ten American adults ages 25 and older had a bachelor’s degree or more education.

Nearly two-thirds of representatives have a graduate degree, and among the 100 current senators, 78 have at least one graduate degree. House members are more likely than senators to have completed a degree at a college or university in the state they represent.
