Mona Charan describes the effects of fatherlessness on boys:

The link between family composition and child welfare is well established. What "Wayward Sons" adds is data on the differentially harmful effects of fatherlessness on sons versus daughters. "Growing up in a single-parent home appears to significantly decrease the probability of college attendance for boys, yet has no similar effect for girls." Boys from such homes "are 25 percentage points more likely to be suspended in the eighth grade than girls from these households, whereas the corresponding gender gap between boys and girls from households with two biological parents was only 10 percentage points."
