For reasons no one can explain, divorce rates fell significantly in 2014. In fact, divorce rates in America have been plummeting since 2012, which was a reversal in a brief, precipitous rise in the rates following the recession.

A bump up in divorce rates in the years after the recession seemed to suggest that recession-related financial stressors took a toll on marriages nationally, but there’s no way of knowing yet what exactly caused that spike, or why it reveresed a couple years later.

Philip N. Cohen, a sociologist at the University of Maryland, writes on his blog that it’s possible that divorce rates are on a continuing downward slide, and the recession simply produced a lull in an ongoing dive.
