Is there a younger or older crowd in DC?

Most people in DC are young professionals. Because of GW and Georgetown you have a good amount of young people. However, depending on what kind of nightlife you like - most DCers go out to bars or bars that have music playing. Particularly popular to go out to various bars/lounge bars is down 14th St NW.

DC is mainly young professionals 20s-30s. There are also 20,000+ undergrads in the area from the local colleges, so there are a lot of 20 somethings out in DC any given weekend night. There are TONs or bars to go to here in DC. If you're into the club scene, don't get your hopes up. It doesn't come close to places like NYC, LA, Miami, or Vegas. There are some options, but nothing spectacular. 

Each neighborhood in DC has something different to offer, a unique nightlife scene in each area. Regardless, you'll be able to find what you're looking for. 

I would agree there are a lot of students and young professionals in DC. I work on United States Capitol and the majority of staffers are in their twenties and early thirties.

DC is a younger crowd of "young professionals."  

The night life is OK, but harder to find the dive bars some of us covet. And, it's all very expensive.

Definitely a younger crowd! Especially in the Northern Virginia area, you'll find some great bars and night life.

Hi Hillary! It definitely depends what you mean by younger and older - but i would say yes, there are lots of really young people (college-age interns and recent grads) and a strong contingent of slightly older, late 20s/early 30s people as well.  

Of course as people start to have kids they tend to move out to Maryland and Virginia, but that is changing with the city and more and more people are staying. I think it's a great mix! 

Nightlife in DC continues to get better and better - especially if you like music. There aren't as many "club" places (of top 40 music-fame) as some other cities. But hey, to me that's a good thing, so it all depends on your tastes!
