A new study from Portland State University has been released, regarding if heterosexual marriage rates drop in the presence of legal same-sex unions. It concluded that they do not.
Since the fight for marriage equality began, conservatives have been insisting that changing who qualifies to marry would damage the institution by causing heterosexual marriage rates to drop, but haven’t had anything to back it up.
To see if the claim had any merit, the study looked at the marriage rates among opposite-sex couples in all fifty states, as well as the District of Columbia, from 1989 to 2009, to see if there were any shifts after various states legalized civil unions or marriage for same-sex couples.
According to the data, heterosexual marriage rates remained steady after the passing of such laws in every state, and were approximately the same as in those where same-sex unions did not have any civil recognition, leading researchers to conclude that there is no connection between the two.
The lead researcher for the project, Alexis Dinno, published their findings in an article titled “Same Sex Marriage and the Perceived Assault on Opposite Sex Marriage” in the academic journal PLOS ONE, where it can be viewed by the public.
