The Center for State Foster Care and Adoption Data, operated by Chapin Hall at the University of Chicago, supports child welfare agencies in using longitudinal data to improve outcomes for children. For the purposes of this article, the authors analyzed data for 14 states from 2000 through 2008 to examine trends in foster care placement, length of stay, stability, reason for discharge, and reentry to placement. One of the findings is that the number of infants entering foster care is on the rise; however, younger infants are less likely to experience disruptions in their placement. The result of the analysis underscores that infants in foster care experience unique challenges and vulnerabilities compared with older children.
