The end of marriage as we know it

The Hill reports:

A research team at the University of Pennsylvania recently attempted to calculate the exact structural toll of this financial shift. The sociologists tracked 544,911 opposite-sex couples across 29 affluent nations over a 16-year period, analyzing a dataset comprising 437,102 married pairings and 107,809 cohabiting couples. The findings were sobering. Couples where the woman holds higher economic or social status are 36 percent more likely to split than those built on a more traditional division of labor.
