Using a longitudinal sample of eighth graders who lived with both biological parents in 1988, we estimate the increased risk of dropping out among students whose two-parent families experienced disruption over the subsequent 4 years. We differentiate the impact on school dropout of initial family income before family disruption from income change after the marriage ends. This approach helps to disentangle two interpretations of the relation between income and family structure. Our results suggest that both measures of income are significant contributors of the risk of dropping out for children whose families became mother-only families. When income loss is taken into account, along with initial income and other family, demographic, and prior school achievement factors, there is no evidence of increased risk of dropout among children who began to live with a single mother during the 1988-1992 period.
