D.C. has a higher percentage of residents who identify as lesbian, gay, bisexual, or transgender, reports a new Gallup survey. All told, 10 percent of the city’s residents say they are LGBT, twice the amount in second-place Hawaii. In Maryland it’s 3.3 percent and in Virginia it’s 2.9 percent; North Dakota sits at the bottom of the list with only 1.7 percent.

The survey included over 200,000 interviews conducted from June to December 2012, and Gallup calls it the “largest single study of the distribution of the LGBT population in the U.S. on record.” The firm also had this to say about some of the results:

While the variation in LGBT identification across states is relatively small, findings do suggest some evidence that the variation is not entirely random. Social climates that promote acceptance of or stigma toward LGBT individuals could affect how many adults disclose an LGBT identity. LGBT people who live in places where they feel accepted may be more likely than those who live in places where they feel stigmatized to reveal their sexual orientation or gender identity to a survey interviewer.

That, of course, speaks the usual caveats: D.C. has been gay-friendly for a while, and it’s a fully urban environment. (Additionally, the survey’s margin of error was slightly higher for D.C. than it was for the 50 states.) When stacked against other cities, it ranks well—but not tops. Last month The Advocate listed D.C. as the country’s fourth-gayest city.
