Despite popular belief, the divorce rate in the U.S. is actually well below 50%. It sounds clever to say that you have a 50-50 shot of staying married, but the odds are better than that in reality. Something like 39% of U.S. marriages end in divorce. Many experts attribute the steady decline in the divorce rate to the fact that young people have proven to be more likely to wait to get married and more likely to stay in those marriages. This is a tough one to pin down because couples can have multiple reasons for getting divorced — as in, he’s lazy, a liar, AND cheating on me. However, researchers have surveyed divorced couples to gain insight into the main factor (or final straw) driving them to exchange their marriage certificate for a divorce certificate. The most common final straws reported in the survey were infidelity (59%) and too much arguing (57%), and domestic violence (23%). Financial problems also played a factor in about one in three of the divorces. Most notably, 73% of respondents agreed that a lack of commitment was a major contributing factor in why their marriage didn’t work.
