According to most recent estimates, over 530,000 children are in foster care in the United States. These children live in a variety of settings, including non-relative foster homes, the homes of relatives, and group homes. Information on the characteristics of these children has mostly been drawn from small studies of children in select localities. Other studies provide only a limited amount of information, though for a broader population of children. NSCAW expands the existing literature by describing the demographic characteristics and well-being of a national sample of children who had been in foster care for 1 year.
