D.C. has highest concentration of gay households
As this map on The Economist website shows, the highest concentration of households headed by gay couples, according to U.S. Census data, are in states that recognize same-sex partnerships or marriage. According to the Williams Institute, a gay rights think-tank at UCLA, D.C. has the highest proportion of gay households in the country, with 14 for every 1,000 headed by same-sex couples. (The national average is 4.7.) Though Maine has the second highest concentration, with more than eight same-sex households for every 1,000, that could soon change: voters recently decided to repeal legislation recognizing gay marriage. And as the map indicates, gay couples are least likely to live in the heartland, which is also a Republican stronghold.
