This paper examines the hypothesis that high levels of residential mobility among nonintact families account for part of the well-known association between living in a nonintact family and dropping out of high school. Children from single-parent families and stepfamilies are more likely than children from two-parent families to move during the school year. As much as 30% of the difference in the risk of dropping out between children from stepfamilies and children from intact families can be explained by differences in residential mobility. Previously, mechanisms explaining school failure on the part of children in nonintact families were more plausible for children in single-parent families than for children in stepfamilies; high levels of residential mobility apply to both groups of children. In addition, residential mobility lends itself to manipulation by public policy, with potentially remedial effects for vulnerable children.
本文检验了这样一种假设，即非完整家庭中较高的居住流动性是造成生活在非完整家庭与高中辍学之间众所周知的关联的部分原因。单亲家庭和再婚家庭的孩子比双亲家庭的孩子在学年期间更有可能搬家。再婚家庭孩子与完整家庭孩子在辍学风险上高达30%的差异可以用居住流动性的差异来解释。以前，解释非完整家庭中孩子学业失败的机制对单亲家庭的孩子比对再婚家庭的孩子更具合理性；高居住流动性适用于这两组孩子。此外，居住流动性便于公共政策进行调控，可能对弱势儿童产生补救作用。
