A new study reveals great news about same-sex couples in America.

Same-sex couples really like marriage. That’s the news from the Williams Institute at UCLA School of Law, which studied the rate of marriage and divorce of same-sex couples in the year since the Supreme Court struck down part of DOMA.

A major finding reveals that currently,Â same-sex couples are about half as likely to divorce as different-sex couples. And same-sex couples married at a rate about double in 2013 versus in 2102.

Married same-sex couples are divorcing at a 1.1 percent rate, compared to a 2 percent rate of different-sex couples, the Williams Institute notes.

“In early 2014, the Williams Institute collected administrative data on marriages, civil unions, and domestic partnerships of same-sex couples in the 23 states that offered these statuses at the time data collection began,” the study finds. “Two states provided data on divorces: New Hampshire and Vermont. Six states provided data on civil union and domestic partnership terminations: California, D.C, New Hampshire, New Jersey, Washington, and Wisconsin.”

When the study was expanded to all legal relationships in eight states, like civil unions and domestic partnerships, the rate of dissolution grew to 1.6 percent annually.

The Williams Institute also found differences in female same-sex couples versus male same-sex couples.

“The first analysis shows that female couples are more likely to formalize their relationships than male couples. Female couples account for just over half (51%) of all same-sex couples in the U.S. However, data from the state agencies show that 64% of same-sex couples who entered into legal statuses were female couples.”

The study also finds that the SCOTUS decision last summer greatly impacted the decision to marry, even in couples who lived in marriage equalityÂ states. Â Calling it “the Windsor effect,” they note that theÂ “data show that the number of same-sex couples who married nearly doubled in marriage equality states from 2012 to 2013.”
