A year after the U.S. Supreme Court legalized same-sex marriage nationwide, nearly half of same-sex couples living together are married, a big jump in numbers, according to a new Gallup poll.

Before the landmark decision, 38 percent of cohabiting same-sex couples were married. In the past year, that increased to 49 percent. Before last year, same-sex marriage was legal in some states and illegal in others, but the new poll shows marriage grew significantly in both types of states. The new data comes just days ahead of the one-year anniversary of the Obergefell v. Hodges ruling June 26. And it gives unique statistical insight into the LGBT population.

For example, even as marriages among cohabiting same-sex couples increased, the percentage of those living with a partner actually decreased. It suggests that while many who were already living together got married in the past year, a whole lot of couples also simply stopped living together or considering themselves to be domestic partners. And even with the increase, only one in 10 adults in the LGBT population as a whole currently report being married.

And in follow-up research, Gallup analysts said they find that same-sex marriages may be leveling off, suggesting there was an initial burst of marriages in the first few months after the ruling, but little increase since then. In a note accompanying the survey results, Gallup’s analysts said they think in coming years, growth in same-sex marriages will happen more as a long-term trend rather than short-term.

“This is especially likely given that the U.S. LGBT population is decidedly young,” Gallup said, “and many who one day want to marry a same-sex spouse are not currently at a point in their lives when they are likely to seriously consider marriage.”

Meanwhile, in the year since the Supreme Court ruling, bathroom rights have emerged as the new frontier for the legal fight over LGBT rights. In a deep report on the subject, Post reporters found that:

In the first half of 2016 alone, 87 bills that could limit LGBT rights have been introduced, a steep increase from previous years. The latest wave of legislation comes at the heels of the Supreme Court decision to legalize same-sex marriage in June 2015.
