Voters turned out on Tuesday at rates not seen in a midterm election in half a century, driven by strong opinions of President Trump and a string of competitive races in states where robust contests have been rare.

It could be months before we know the demographic breakdown of who voted in this election, but there are early indications that turnout boomed especially among women, Latinos and young people. (Read more here about what the exit polls said about 2018’s voters.)

We crunched the numbers and spoke with experts. Here’s what the data can tell us (and what it can’t yet).

How high was the turnout?

Based on preliminary — but incomplete — data made available by the states and analyzed by Michael McDonald, a professor of political science at the University of Florida, it looks as if more than 113 million people voted, which would be at least 48 percent of eligible Americans. That’s up from the 83 million votes cast in 2014, when Republicans made sweeping gains in the House and the Senate. In fact, it’s closer to the turnout in the last presidential election — about 138.8 million — than to the last midterms.
