The April issue of Glamour has some statistically driven advice for D.C. women: Stay single and stay happy. A survey the magazine conducted with the online dating service Match.com found that 86.7 percent of District women interviewed are happy with their dating lives.

The survey, The Washington Post reports, questioned 5,000 single women over 21 across the 10 largest metropolitan areas in the U.S.

In one respect, Glamour’s findings that the District and its immediate environs so endlessly datable shouldn’t be much of a surprise. After all, it was only in January that The Daily Beast ranked us as the 10th-best place to get a date.

Then again, other recent polls have called D.C. one of the nation’s rudest, ugliest and least tolerant cities. Another survey last October—conducted on behalf of Combos, of all things!—also pegged the District with a deficit of manly men.

So, just why should single women be so happy here? Call it the revolving door effect:

“Washington has people coming and going with each administration,” Helen Fisher, an anthropologist and Match.com’s chief scientific advisor, told the Post. “So women have a continually renewed source of men.”

But what are we up against in this ranking of dating pools? Well, Boston finished dead last, with single women there reporting that one in eight men expect sex on the first date. And Philadelphia came in at No. 2.

NBC4 notes that the Glamour/Match.com survey is a more optimistic counterweight to an article last year by Bloomberg News that suggested that Washington’s workaholic culture makes this town quite difficult for single women.
