A survey in Holland says heterosexual couples were less like to marry after same-sex marriage was legalised. It seems conservatives are right to worry about weakening this tradition.
For decades, conservative opponents of same-sex marriage have been making a brazen claim. Extending marriage rights to gay couples, they say, will weaken the marriage institution.
In the near-absence of reliable data, their arguments have relied almost entirely on hypothesis. However, a new study, published [in 2014] in the social science journal Demography, could offer same-sex marriage opponents some of the first empirical evidence in support of their theories. If the study’s findings are correct, same-sex marriage in the Netherlands decreased the opposite-sex marriage rate in all but the most conservative groups…
The paper in question, “The Effect of Same-Sex Marriage Laws on Different-Sex Marriage: Evidence From the Netherlands”, by Mircea Trandafir, was published in … the journal Demography. The author attempted to find the effect on the marriage rate of a 1998 domestic partnership law and 2001 same-sex marriage law in the Netherlands. Its conclusions have mostly escaped attention—partly because of a vague abstract.
The paper contains two statistical analyses. The first is a regression on aggregate (country-level) data that compares the Netherlands to a control group of OECD countries over a number of years, while the second is a time series analysis of individual-level data. In the abstract, the author writes that according to the first model, “neither law had significant effects on either the overall or different-sex marriage rate”. This is true at the 5% level, but it’s worth noting (in the context of the entire paper) that the effect of the same-sex marriage law on the marriage rate was significant at the 10% level—implying that there is only a 1 in 10 chance that Dutch marriage rates in the absence of the same-sex marriage law would have fallen as much as they did in reality. The overall trend from 1988 until 2005 is described in the paper:
“As expected, the actual rates are relatively close to the synthetic marriage rate [control group rate] between 1988 and 1997, the period used to construct the synthetic control. After the introduction of registered partnership, the three rates are all higher than the synthetic marriage rate, but they all fall below the synthetic rate at some point after 2001, the year in which same-sex marriage was legalized.”
