Interestingly enough, Massachusetts, the state which I suspect has the high number of feminists (as a percentage of population), has the lowest divorce rate in the nation. The states with the highest divorce rate are the Bible Belt states. The degree to which a woman is a feminist has absolutely nothing to do with the likelhood that she will initiate divorce, or with divorce rates in general. There are other variables in play here, multiple numbers of them.
Probably because it also has a low marriage rate when adjusted per capita. If everybody's cohabiting, only the truly dedicated get married, and they tend to stay married.

My guess is that it's because in the more "conservative" states, it's more socially "necessary" to get married (i.e. family pressures, work pressures, easier to get a nicer apartment, social respectability in general.) When the marriage doesn't work out, they divorce. Also, the more southern states generally have younger ages at marriage, and those marriages tend to not last as long.
