You've probably heard the jokes. People call the U.S. Capitol the most expensive nursing home in the world. It’s a common punchline. But if you actually look at the current members of Congress by age in 2026, the reality is a bit more complicated than just a bunch of octogenarians arguing over a gavel.
The 119th Congress is a weird mix of eras. You’ve got people who remember the Great Depression serving alongside people who don’t remember a world without TikTok.
Honestly, the "gerontocracy" label isn't entirely wrong, but it's shifting. For the first time in forever, the House of Representatives is actually getting younger. Generation X has finally overtaken the Baby Boomers as the largest voting bloc in the House. It’s a huge deal. It’s like the "sandwich generation" finally moved into the master bedroom.
The Old Guard: Why the Senate Still Skews Gray
The Senate is where the age gap really hits you. While the House is trending younger, the Senate is still very much a "Boomer and Silent Generation" club.
Chuck Grassley (R-Iowa) is the king of this hill. Born in 1933, he’s currently 92 years old. Think about that for a second. When he was born, the movie King Kong had just premiered in theaters. He’s been in the Senate since 1981. He is the longest-serving Republican in Senate history, and he shows no signs of slowing down his legendary Twitter updates about "u know what" (dead deer on the road, for those not in the loop).
But it’s not just Grassley. The leadership is seasoned, to put it mildly.

- Bernie Sanders (I-VT) is 84.
- Mitch McConnell (R-KY) is 83.
- Jim Risch (R-ID) is 82.
- Angus King (I-ME) is 81.
- Dick Durbin (D-IL) is 81.
The average age in the Senate usually hovers around 64 or 65. It’s basically the age where most Americans are eyeing a retirement package and a move to Florida. In the Senate, that’s just when you’re starting to get the good committee assignments.
The House Shift: Gen X and Millennials Move In
Over on the other side of the Capitol, things look a bit different. The House of Representatives is where you see the real generational churn.
Maxwell Frost (D-FL) is the name everyone brings up. He’s 29 now, and he’s still the only Gen Z member. He was 25 when he first got elected. He’s literally the "Baby of the House." Then you have the newcomers from the 2024 elections like Brandon Gill (R-TX) and Addison McDowell (R-NC), both in their early 30s.
What’s interesting is that the median age in the House is now around 57. That’s still "old" by most standards, but it’s a far cry from the Senate’s mid-60s.
Breaking Down the Generations in the House
- Generation X (1965-1980): 41% of the House. They are finally the majority.
- Baby Boomers (1946-1964): 39%. They held the crown for decades, but the tide has turned.
- Millennials (1981-1996): 15%. Slowly growing, especially in suburban swing districts.
- Silent Generation (1928-1945): 4%. These are the veterans like Hal Rogers and Eleanor Holmes Norton, both 88.
Why does this matter? Well, Gen X and Millennials bring different baggage. They care about student loans, housing prices, and digital privacy in a way that someone born before the invention of the microchip might not. When you see a 33-year-old like Yassamin Ansari (D-AZ) talking about the "future of work," it sounds a lot different than when a 90-year-old says it.

The "Freshman" Exception
Just because you’re new doesn’t mean you’re young. This is a huge misconception. Take Jim Justice (R-WV). He entered the Senate in early 2025 as a "freshman," but he was 73 at the time. He became the oldest freshman senator in history.
Political careers often start late. Many people wait until their kids are grown or they’ve made money in the private sector before running for office. This keeps the "average" age high, even when there's a lot of turnover.
Is Age Just a Number or a Policy Problem?
There’s a lot of debate about whether we need age limits. Honestly, some of the older members are sharp as a tack. Others... well, we’ve all seen the viral videos of "freezing" at podiums or confusing world leaders.
The real issue isn't just "being old." It's about representation. The median age of the American public is around 38. The median age of Congress is 59. That’s a 20-year gap.
When Congress debates things like AI regulation, social media algorithms, or the long-term solvency of Social Security in 2050, the people making the decisions won't be around to see the consequences. That’s the "skin in the game" argument. Younger members like Katie Britt (R-AL), who is 43, often talk about being a "mom in the Senate" to bridge that gap.

What to Watch Next
If you're tracking the current members of Congress by age, the 2026 midterm elections are going to be the next big data point. We already have about 10% of the House announcing they won't run for reelection. Most of those are from the older cohorts.
We are in the middle of a massive "passing of the torch." It’s slow. It’s clunky. But it’s happening.
Actionable Insights for Following Congressional Demographics:
- Check the "Freshman Class" profiles: Don't just look at the leaders. The newcomers tell you where the parties are heading.
- Watch the Committee Chairs: Power in D.C. is still mostly tied to seniority. Even if the House is 41% Gen X, the people running the powerful committees (Ways and Means, Appropriations) are still mostly Boomers.
- Follow the Retirements: Every time a member of the Silent Generation retires, they are almost always replaced by someone 20-30 years younger. This is where the real change happens.
- Look at the "Young Elected Leaders" (YEL) data: Organizations like the Rutgers Center for Youth Political Participation track members under 35. This is the best way to see the "Gen Z/Millennial" pipeline in action.
The shift is real, even if Chuck Grassley is still outperforming people half his age on the campaign trail.
Next Steps to Track Congressional Trends
- Visit the official Biographical Directory of the United States Congress to search for any member's birth date and career history.
- Monitor Pew Research Center's "Changing Face of Congress" reports, which are updated every two years following elections to provide new generational snapshots.
- Cross-reference age data with OpenSecrets to see if younger members are raising money differently (e.g., small-dollar digital donors vs. traditional PACs).
