This series of research briefs explores issues of family homelessness that are especially relevant to HHS, to state and local decision-makers, and for programs. The Child Separation among Families Experiencing Homelessness brief explores child separations among families experiencing homelessness. It builds upon the fourth brief in this series, “Child and Partner Transitions among Families Experiencing Homelessness,” which looked at family separations and reunifications in the 20 months after being in emergency shelter and the association between family separation and recent housing instability following an initial shelter stay. This new brief provides a more detailed examination of these families and their children before and after the initial shelter stay, revealing more extensive and persistent levels of child separation. It gives detailed characteristics of separated children and examines whether future child separation after a shelter stay is related to either housing instability of previous separations.
