2024 State Elections by the Numbers

With the counting and recounting finished, the 2024 state elections are officially over. It's time to look at a few final statistics to see how the voting affected legislatures and the states.

Even though the numbers are "final," it's still a snapshot in time. It's common for a handful of legislators to leave office between the election and swearing in, so the numbers can and do change. Some lawmakers will get called into the executive branch, for instance, and even beyond the first flexible weeks after an election, vacancies can arise. In chambers with narrow margins, those openings can have consequences on party control.

Election Results by the Numbers

99: Total number of legislative chambers in the states. Nebraska has a unicameral legislature.

98: Total number of partisan chambers in the states. Nebraska's senators are elected on a nonpartisan basis.

2: Number of chambers controlled by a coalition, rather than by the party holding the most seats. Both chambers of the Alaska Legislature have a majority of Republican members, but both are run by Democratic-led coalitions.

46: Number of legislatures in which the same party controls both chambers. Both parties have fewer legislatures under their control now than before the election. Republicans hold 28 and Democrats hold 18 (down from 20).

3: Number of split legislatures in which the two chambers in a state are held by different parties. Three is an increase from the historic low of just one after the 2022 election.

• Michigan: Democrats held the Senate; Republicans flipped the House.
• Minnesota: Democrats held the Senate; the House changed from Democratic control to a tie. The parties will negotiate a power-sharing agreement.
• Pennsylvania: Republicans held the Senate; Democrats held the House.

2: Number of chambers nationwide that changed control after the election. Minnesota's House flipped from Democratic control to a tie, and Michigan's House flipped from the Democrats to the Republicans.

3: Number of chambers that flipped in U.S. territories. The unicameral Guam Legislature flipped from Democratic to Republican control, and Puerto Rico's House and Senate each flipped from the Popular Democratic Party to the New Progressive Party, the island's pro-statehood party.

0: Number of gubernatorial offices that changed party control. Both before and after the election, 27 Republicans and 23 Democrats held the top state executive offices.

38: Number of states under one-party control, with both legislative chambers and the governor's office controlled the same party (aka trifectas). Republicans hold 23, just as they did before the election, and Democrats hold 15, down from 17 before the election.

7,575: Total number of American legislators, including 7,386 legislators in the 50 states, plus 189 in Washington, D.C., American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands.

1,454: Number of new legislators elected in 2024 in the states and territories; the figure represents 24.3% of the 5,808 total legislators on this year's ballot, and 19.1% of all 7,575 legislators.

51: Number of legislative seats Republicans have netted nationwide since the 2022 elections. It is common for the party of the winning presidential candidate to gain legislative seats; 50 is lower than average, but not by much.

32: Percentage of state legislators who are women (the same as after the 2022 election). Colorado, Nevada and New Mexico have more female than male legislators.

244: Number of former state legislators who will serve in Congress starting in January 2025: 41 in the Senate and 203 in the House, and 46% of all members of Congress.

63.8: Percentage of the voting eligible population who voted in 2024. The percentage is down from 2020, when 66.4% voted. (Source: University of Florida Election Lab)
