Just in case you thought diversity was coming to Congress, behold the U.S. Senate.

The below graphic tracks demographic changes in our 100 senators compared to both 10 years ago and 20 years ago. And if you look at race and gender, you will indeed see some increasing diversity — some.

Where that diversity momentum stops, though, is when you look at age and education. In fact, the Senate is getting slightly older and more highly educated.

In fact, while 44 senators had private-school educations two decades ago, 56 do today. And while three senators back then had no college degree, just one — Sen. Mark Begich (D-Alaska) — has none today. And he might not be in the Senate much longer after Tuesday's election.

The man who might replace him? Harvard-educated former Alaska attorney general Dan Sullivan (R).
