"So This Is Where All The Single Men And Women Have Been Hiding"

Some information that may be relevant if you're single and looking to mingle in U.S. cities.

Women outnumber men in the big three power centers of the Northeast: Washington, D.C.Boston, and New York. The ratio is highest in the Bethesda-Rockville-Frederick metro, which is just over the Maryland border from Washington, D.C. Nine of the 10 metros with the highest ratio of women to men are in the East: Oakland is the only exception. . . . 

What do these neighborhoods have in common? Billy Joel was right: in most metros, the neighborhood with the highest ratio of men to women is in or near downtown, as well as in recently redeveloped neighborhoods like Boston’s Waterfront or Long Island City. Even man-rich Rosslyn is a major employment center despite being in northern Virginia, outside of Washington D.C.

The neighborhoods with the highest ratio of women to men tend to be more residential, like San Francisco’s Marina and Seattle’s Queen Anne, and more upscale (and safe), like the Upper East Side and Upper Connecticut Avenue. Some are near major retail centers, likeChicago’s Near North Side, the Beverly Center in LA, and Atlanta’s Perimeter Mall, though Houston’s Great Uptown neighborhood — which skews toward men — is near the Galleria, Texas’s largest mall.
