More and more wives are now outnumbering their husbands. They also stay together longer.

Not only are wives outnumbering husbands in marriages, they are also less likely to end in divorce than in the past.

Couples who married in the late 1960s and 1970s were 70% more likely to divorce than couples whose husbands earned more if their wives earned the same or slightly more than their husbands. According to research By Christine Schwartz and Pilar Gonarons-Pons, sociologists at the University of Wisconsin-Madison and the University of Pennsylvania. However, for couples who married in the 1990s, women-breadwinner couples had a 4% higher divorce rate than male-breadwinners.
