While the median age rose in the U.S. and just about every state over the last decade, it fell in only one place—D.C.

According to a tweet from The Hotline’s Reid Wilson, the U.S. Census Bureau announced this week that D.C. was the single place to get younger. According to Census numbers we reviewed, in 2000 the city’s median age stood at 34.6; after the 2010 Census, it dropped to 33.7. Nationwide, the median age rose from 35.3 to 37.3.

D.C. isn’t the youngest state in the nation, though—that honor is reserved for Utah, where the median age is 29.5. (In 2000, it was 27.1.) Texas tied D.C. for second place, with Alaska taking third at 33.8. The oldest state? Maine, at 43.2.

The City Paper also reports on another demographic trend—while the number of white babies fell across the country, they were on the increase in D.C., though by a smaller proportion than Hispanic babies.

From 2010 to mid-2011, D.C. was found to be the fastest-growing state in the country, adding close to 17,000 residents.

Census Bureau: The avg age of the population went up in every state in the union in the last decade. Only DC got younger.
