Data Researcher/Curator

WASHINGTON —

The 119th Congress is older than the previous Congress, with lawmakers in the House of Representatives having a median age of 58, up from 57.9, and senators having a median age of 66, up from 65.3.

The current median age of all of Congress is 60 years, while the median age of the U.S. population was 39.4 as of July 1, 2025, according to the U.S. Census Bureau. Nearly 94% of members of Congress are older than the nation’s median age.

The Get the Facts Data Team pulled the median, or middle value, rather than average because it is less affected by outliers and provides a better measure of the typical age. Ages are as of July 27.

In the U.S. House of Representatives, 402 representatives are older than 39. There are currently four vacant House seats: California’s 14th District, Florida’s 20th District, Georgia’s 13th District and Texas’s 23rd District.

Every senator except one — Sen. Jon Ossoff, D-Georgia — is older than 39.

Here’s how the age distribution breaks down by chamber and state.

Who are the youngest and oldest members of Congress?

Twenty-nine members in the House of Representatives are 39 years or younger, making up about 7% of the chamber. Rep. Maxwell Frost, D-Florida, is the youngest member of Congress, at 29. He was 25 when he was sworn into office in 2023.

Rep. Brandon Gill, R-Texas, and Rep. Addison McDowell, R-North Carolina, are the second- and third-youngest members of the House, both 32.

In the Senate, Ossoff is the youngest, and he first took office when he was 33. Sen. Tim Sheehy, R-Montana, is the second-youngest at 40.

The oldest member in the House is Rep. Harold Rogers, R-Kentucky, at 88. Sen. Chuck Grassley, R-Iowa, is the oldest member of the Senate and of Congress at 92.

The Census Bureau considers those age 65 and older to be at retirement age. In the House, 134 members are 65 or older; that’s more than 30% of the chamber. In the Senate, more than half of the chamber is 65 or older. Across Congress, about 36% of lawmakers are at or above retirement age.

Which states have the youngest and oldest lawmakers?

Colorado has the youngest median age among its congressional lawmakers at 47. The median age of its House members is 45, while its senators have a median age of 68.

Vermont has the oldest median age among congressional delegations at 79. Congressional representatives for Idaho were the second-oldest at 75 years.

There currently is no age or term limit in Congress. The U.S. Constitution does set a minimum age to serve, with the minimums for the House and Senate at 25 and 30 years old, respectively.

Members of the House are elected every two years, while senators serve six-year terms. Representatives continue to serve as long as they are elected by their constituents.
