Reported at Christianity Today:
"...[E]vangelical women tend to be happier in their marriages than other women, particularly when both the wife and the husband attend church on a regular basis. This idea that Christians are just as likely to divorce as secular folks is not correct if we factor church attendance into our thinking. Churchgoing evangelical Protestants, churchgoing Catholics, and churchgoing mainline Protestants are all significantly less likely to divorce.
How much less likely? I estimate between 35 and 50 percent less likely than Americans who attend church just nominally, just once or twice a year, or who don't attend church at all. It is true that people who say they've had a born-again experience are about as likely to divorce as people who are completely secular. But if you look at this through the lens of church attendance, you see a very different story...."
