The 119th Congress was sworn in Jan. 3 and will end in 2027. The 2024 election saw all 435 House seats and 34 Senate seats up for grabs. About 156 million people voted, up from 112 million in 2022 (elections have higher turnout in years when the presidency is on the ballot). It was the second-largest voter turnout in U.S. history.

The 2024 election had turnout of about 63.9%, slightly below the 66.6% during the pandemic-era election of 2020, when every American was mailed a ballot.

The 1960 election between John F. Kennedy and Richard Nixon (63.8%) was the only other election in the past 112 years to exceed 63% turnout.

Early and mail-in balloting remained popular in 2024. A total of 88,380,679 ballots were cast. Of early ballots, 52% were cast in person, while 48% were mailed.

Republicans won 220 House seats compared with 215 by Democrats. That majority is two seats smaller than what the Republicans won in the 2022 midterm elections.

The margin will decline slightly because Rep. Matt Gaetz of Florida resigned, and two other Republicans accepted cabinet positions. Special elections for their seats will not come until spring.

There are nine new senators (four Democrats, five Republicans) and 62 new representatives (32 Democrats, 30 Republicans).

Republicans will hold 53 seats in the new Senate, a gain of four. The Republicans last controlled the Senate in 2020. The four seats that flipped were in Montana, Ohio, Pennsylvania and West Virginia.

Racial and ethnic diversity

The Pew Research Center says that despite growing racial and ethnic diversity on Capitol Hill, members of Congress still are far more likely than the overall U.S. population to be non-Hispanic White (75% vs. 59%). This gap is about as wide as it was in 1981, when 94% of members of Congress were White, compared with 80% of the U.S. population.
