Glory Johnson and Brittney Griner (Forward Times Online)

Phoenix Mercury star Brittney Griner filed for an annulment from her wife Glory Johnson, who plays for the Tulsa Shock. The two WNBA stars married May 8th, and Johnson announced her pregnancy June 4th.

With acceptance of same-sex marriage gaining ground, divorce will naturally follow. But how many same-sex marriages end?

It’s hard, and probably too early, to find concrete and up-to-date statistics on this. In 2011, UCLA’s Williams Institute found that same-sex couples who’ve formalized their commitment had a divorce rate of 1%+. This is lower than the annual divorce rate of heterosexual married couples, which is 2%.

Around 150K same-sex couples have married or otherwise committed to each other, so that would mean around 3K same-sex couples divorce each year. I couldn’t find any stats solely for annulments.

But in 2013, Pew Research Center’s FactTank found that same-sex marriages numbered around 71K+. It did take into account that there might be some underreporting going on.

As time passes and more same-sex marriages and divorces/annulments/separations are recorded, we’ll be able to see a clearer picture of any trends.
