Wait, wait.
I assumed "divorce rate" meant percent of marriages that end in divorce. That would be a meaningful statistic.
But if you compare it to "marriage rate", which I have to assume means rate of marriages per capita or some such, then either you're a) comparing apples to oranges, or b) comparing per capita numbers in both cases, which I don't think is that meaningful.
Anyone want to shed some light on this? I dunno what the source of these numbers is.
