U.S. 119th Congress Averages 59 Years Old, Third Oldest in Nation's History

The age composition of the United States government continues to draw public attention, with the 119th Congress, seated in January 2025, averaging approximately 59 years old, making it the third oldest in U.S. history. This demographic reality prompted commentator Christine Bannan to state on social media, > "The U.S. is a gerontocracy." This sentiment reflects ongoing discussions about the significant age gap between elected officials and the general American populace.

The average age in the Senate for the 119th Congress stands at around 64 years, while the House of Representatives averages about 57 years. This contrasts sharply with the median age of the overall U.S. population, which is approximately 39 years old. The disparity highlights a notable generational divide in political representation.

Analysis of the generational makeup reveals that Baby Boomers, born between 1946 and 1964, continue to hold a majority in the Senate. However, in the House of Representatives, Generation X (born 1965-1980) has surpassed Boomers to become the largest generational group for the first time. Despite this shift, Millennials and Generation Z remain significantly underrepresented compared to their proportion in the national population.

The presence of a largely older Congress can influence legislative priorities and perspectives. While experience is often valued, some experts suggest that younger lawmakers may be more attuned to issues like climate change, student debt, or the impact of emerging technologies. The oldest serving members include Senator Chuck Grassley (R-IA) at 91 and Delegate Eleanor Norton (D-DC) at 87.

Conversely, the 119th Congress also includes younger members like Representative Maxwell Frost (D-FL), the sole Gen Z member at 28. The ongoing debate about age in leadership underscores a broader conversation about how well the demographic profile of elected officials mirrors the diverse age groups they represent across the nation.
