Interactive map: the oldest and youngest Congressional delegations

Placeholder while article actions load

Earlier today I looked at trends in average Congressional age over time and found that relative to everyone else, Congress is actually getting younger. It's also interesting to look at the age of Congressional delegations at the state level for the 113th Congress.

Alaska can lay claim to the oldest House delegation, at 80 years. But Alaska's "delegation" consists solely of Don Young, who has held that state's lone House seat since 1973. If we exclude similar single-representative states like Vermont, the prize for oldest delegation goes to West Virginia, who's representatives average 64 years.

At the opposite end of the age spectrum, South Dakota's Kristi Noam is the youngest House delegation at 42 years. But again excluding single-representative states, the 46-year-old Kansas delegation is the youngest.

One thing that stands out in the map above is the swath of young delegations from states in the middle of the country. We normally associate youthful dynamism with coastal metropolitan areas, but as far as the House is concerned that energy seems to be coming from the heartland.

On the Senate side, Democrats can lay claim to both the oldest and youngest delegations. California's Dianne Feinstein and Barbara Boxer average out to 76.5 years, the oldest delegation, while New Jersey's Cory Booker and Robert Menendez are the youngest at 52.

Most states' Senate delegations are older than their House delegations, but there are a few notable outliers. Texas' Senators average out to a youthful 52.5, while its 36 representatives are 61 years old on average. That latter number is bolstered somewhat by Representative Ralph Hall, who at 90 is the oldest member of the House.
