In March 2010, same-sex couples in the District were able to marry for the first time. The D.C. courts don’t break down marriage statistics by the sexes of the newlyweds, but the gay marriage boom is still very much visible in the city’s overall marriage stats. To wit: Between 2005 and 2009, the number of marriage license applications hovered between 2,500 and 3,100 a year, according to D.C. Superior Court figures. In the year beginning March 3, 2010, the day marriage licenses became available, that figure jumped to 6,604. Applications dipped slightly in the next two years, before leaping suddenly in mid-2013, more than doubling between June and July of that year. One reason? In late June, the Supreme Court invalidated the Defense of Marriage Act, granting federal recognition of same-sex marriages in jurisdictions where they’re legal. As it turns out, when people are given more marriage rights, they marry more. And the District, which collects a $45 fee from each application, profits in more ways than one.
