As the percentage of LGBT adults in same-sex marriages has increased over the past two years, the percentage in same-sex domestic partnerships has fallen sharply from 12.8% before the Supreme Court ruling to 6.6%.
About half of the decline in same-sex domestic partnerships can be explained by the increase in same-sex marriages. The rest of the decline could mean that others formerly in same-sex domestic partnerships may have stopped living together, or no longer consider a same-sex cohabitant as a “partner.”
