Don't know if there are stats on that. Those who cohabitate before marriage are twice as likely to divorce, or something like that.
Here's an interesting stat. Of couples that practice natural family planning (i.e., no sterilization agents or "birth control"), the divorce rate is under 3%.
Correlation, not causation. People who practice NFP are overwhelmingly devout Catholics, who are already heavily opposed to divorce.
"Of couples that practice natural family planning (i.e., no sterilization agents or "birth control"), the divorce rate is under 3%."
Iteresting... I guess if they know they want a family, they want to stay a family? Makes sense to me.
