The Pew Research Center released an article on some of the findings contained in the Census Bureau’s 2008 American Community Survey. It highlights some trends that tend to support other research showing that people who are older at the time of marriage are less likely to divorce.
[N]umber of divorces within the previous 12 months per 1,000 women — tends to be high in states where women marry young, such as Oklahoma and Idaho. But the same link is not as strong for men: Alaska and Wyoming, for example, are among the top states for recently divorced men, but they are not states where men marry especially young.
Pew also has a lovely interactive map illustrating more of the Census Bureau data on marriage and divorce in the U.S.
