This study examined economic disconnection, an extreme case of economic exclusion in which families lack both employment and cash assistance, among families in the child welfare system. To build hypotheses about the intersection of the child welfare system and economic disconnection we used a multilevel framework that considers federal policy, local practice, and processes within families. We hypothesized that child welfare intervention has the potential to be a mechanism of economic inclusion or exclusion for vulnerable families, with implications for family reunification. We utilized a novel administrative data set containing data from three state agencies to construct income histories of parents relative to their child's placement in foster care (N = 15,159 parents). We identified eight trajectories using group-based trajectory modeling. About two-thirds of parents experience economic disconnection over a three-year period; these families are least likely to reunify. Although providing economic resources to families is typically beyond the scope of child welfare, efforts to minimize the negative impact of child placement on parents' economic connection is likely to improve both the economic inclusion of poor families and family reunification.
