Do Daughters Cause Divorce?

Parents of girls are 5 percent more likely to divorce than parents of boys. Economists first analyzed the data that way in 2003, when Gordon Dahl at the University of Rochester and Enrico Moretti at U.C.L.A., identified that gap, and noted that it widened as you added boys or girls to a family. Parents of three girls, for instance, are 10 percent more likely to split than are parents of three boys. And, they found, an unmarried couple is more likely to marry if they learn their unborn child will be a boy than a girl.
