In this report from the U.S. Department of Health and Human Services, Administration for Children and Families, Office of Planning, Research and Evaluation, data on young children who have stayed in emergency homeless shelters is examined to measure child well-being 20 months after a stay in a shelter. The report considers pre-reading skills, pre-math skills, developmental delays, and behavior challenges to see if homelessness has an impact on these indicators of child well-being, using national norms for young children as a comparison. Also considered are links between a lack of housing or child care stability and well-being.
