WSJ: Gay marriage (helps/hurts) straight marriage

And the answer is? Well, it's in study reported in the Wall Street Journal, in an article by William Eskridge and Darren Spedale (link to Yale Law School since WSJ is so hard to get):

[T]here is no evidence that allowing same-sex couples to marry weakens the institution. If anything, the numbers indicate the opposite. A decade after Denmark, Norway and Sweden passed their respective partnership laws, heterosexual marriage rates had risen 10.7% in Denmark; 12.7% in Norway; and a whopping 28.8% in Sweden. In Denmark over the last few years, marriage rates are the highest they've been since the early 1970s. Divorce rates among heterosexual couples, on the other hand, have fallen. A decade after each country passed its partnership law, divorce rates had dropped 13.9% in Denmark; 6% in Norway; and 13.7% in Sweden. On average, divorce rates among heterosexuals remain lower now than in the years before same-sex partnerships were legalized.

In addition, out-of-wedlock birthrates in each of these countries contradict the suggestion by social conservatives that gay marriage will lead to great increases in out-of-wedlock births and therefore less family stability for children. In Denmark, the percentage of out-of-wedlock births was 46% in 1989; now it is 45%. In Norway, out-of-wedlock births jumped from 14% in 1980 to 45% right before partnerships were adopted in 1993; now they stand at 51%, a much lower rate of increase than in the decade before same-sex unions. The Swedish trend mirrors that of Norway, with much lower rates of increase post-partnership than pre-partnership.

Is there a correlation, then, between same-sex marriage and a strengthening of the institution of marriage? It would be difficult, and suspect, to establish a cause-and-effect relationship between these trends in heterosexual marriage and marriage rights for gays and lesbians. But the facts demonstrate that there is no proof that same-sex marriage will harm the institution of marriage, or children. An optimistic reading of the facts might even suggest that the energy and enthusiasm that same-sex couples bring to the institution of marriage may cause unmarried heterosexual couples to take a fresh look at marriage as an option.

As they say, you can't say it proves same-sex marriage helps straight marriage (any more than that other huge study proved that religion causes dysfunction in society). But it does pretty much prove that it doesn't hurt.

And a lot of us have been saying for a while, now: stopping people from getting married is what hurts marriage.
