Family Disadvantage and the Gender Gap in Behavioral and Educational Outcomes

U.S. women graduate high school at higher rates than U.S. men, but the female-male educational advantage is larger, and has increased by more, among black and low-SES students than among white and high-SES students. We explore why boys fare worse than girls—both behaviorally and educationally— by exploiting birth certificates matched to health, disciplinary, academic, and high school graduation records for over one million children born in Florida between 1992 and 2002. We account for unobserved family heterogeneity by contrasting the outcomes of opposite-sex siblings linked to birth mothers by administrative records. Relative to their sisters, boys born to low-education and unmarried mothers, raised in low-income neighborhoods, and enrolled at poor-quality public schools have a higher incidence of absences and behavioral problems throughout elementary and middle school, exhibit higher rates of behavioral and cognitive disability, perform worse on standardized tests, and are less likely to graduate from high school. We argue that the family disadvantage gradient in the gender gap is a causal effect of the post-natal environment: family disadvantage has no relationship with the sibling gender gap in neonatal health. Although family disadvantage is strongly correlated with school and neighborhood quality, the SES gradient in the sibling gender gap is almost as large within schools and neighborhoods as between them. A surprising implication of these findings is that, relative to white children, black boys fare worse than their sisters in significant part because black children— both boys and girls—are raised in more disadvantaged family environments.
