Big Chart Of The Day


Via FiveThirtyEight.com, this is a chart detailing divorce rates for 43 states (that reported them to the CDC) and correlating data on whether or not each state has same-sex marriages or unions. Nate Silver analyzes:
[T]hose states which have tended to take more liberal policies toward gay marriage have tended also to have larger declines in their divorce rates. In Massachusetts, which legalized gay marriage in 2004, the divorce rate has declined by 21 percent and is the lowest in the country by some margin. It is joined at the top of the list by Rhode Island and New Mexico, which do not perform same-sex marriages but idiosyncratically also have no statute or constitutional provision expressly forbidding them, as well as Maine, whose legislature approved same-sex marriage only to have it overturned (although not banned constitutionally) by its voters.

On the other hand, the seven states at the bottom of the chart all had constitutional prohibitions on same-sex marriage in place throughout 2008. The state which experienced the highest increase in its divorce rate over the period (Alaska, at 17.2 percent) also happens to be the first one to have altered its constitution to prohibit same-sex marriage, in 1998.

Overall, the states which had enacted a constitutional ban on same-sex marriage as of 1/1/08 saw their divorce rates rise by 0.9 percent over the five-year interval. States which had not adopted a constitutional ban, on the other hand, experienced an 8.0 percent decline, on average, in their divorce rates. Eleven of the 24 states (46 percent) to have altered their constitutions by 1/1/08 to ban gay marriage experienced an overall decline in their divorce rates, but 13 of the 19 which hadn't did (68 percent).
Hmmm. I think that this is excruciatingly interesting and would love to see more research on the connection between progressive social policy (on the state level) and decline in divorce rates. I find it difficult to believe that this phenomenon is simply happenstance. Thoughts?
