State Foster Care & Child Welfare Intelligence

Foster care is a temporary living arrangement for children whose parents are unable to safely care for them, typically because of abuse, neglect, parental substance abuse, incarceration, or family crisis. Children in foster care live with licensed foster families, with relatives in kinship placements, in group homes, or in residential treatment programs while a child welfare agency works toward a permanent outcome, most often reunification with the biological family, but sometimes adoption, legal guardianship, or aging out into independent living. Roughly 370,000 U.S. children are in foster care on any given day.

Reunification means returning a child in foster care to the biological parent or parents from whom they were removed. It is the preferred permanency goal under federal law (the Adoption and Safe Families Act) when it can be achieved safely. Reunification typically requires the parent to complete a court-approved case plan, addressing the conditions that led to removal, and be assessed by a caseworker as ready to safely parent again. Nationally, slightly under half of children who exit foster care exit to reunification, with state-by-state variation tracked in our dataset.

State grades are based on each state's reunification rate, ranked against the national distribution from the current AFCARS release (Adoption and Foster Care Analysis and Reporting System), and assigned a letter grade A through F. Grades are relative, not absolute, they identify states whose outcomes are stronger or weaker than peers, not a pass-fail of child welfare quality. Adoption rate, placement stability, kinship-placement share, aging-out rate, and re-entry rate are tracked and shown separately on every state profile, but they do not factor into the letter grade itself. See our grading guide for the exact rate bands and current state counts per grade.

Aging out is the term for a young person leaving foster care without achieving a permanent family, they reach the legal age limit (typically 18, sometimes extended to 21 under state extended-foster-care programs) without being reunified, adopted, or placed in legal guardianship. Roughly 20,000 youth age out of U.S. foster care each year. Outcomes are measurably worse: aged-out youth face higher rates of homelessness, unemployment, early pregnancy, and incarceration than peers who exit with a permanent family. State aging-out rates are a key indicator of system performance.

The Children's Bureau within the Administration for Children and Families (ACF) publishes annual AFCARS reports approximately 18 months after each federal fiscal year ends. PlainFoster refreshes from each AFCARS release as it becomes available and surfaces the source-fiscal-year on every state page. Some states also publish more recent state-level dashboards on different cadences; we note source-date inconsistencies when they materially affect comparability.

Kinship care is foster placement with a relative, most often a grandparent, aunt, uncle, or older sibling, rather than with a non-relative licensed foster family. Federal policy under the Family First Prevention Services Act prioritizes kinship placements where appropriate because research consistently shows better outcomes for children placed with kin: greater placement stability, fewer school changes, stronger sibling connections, and reduced trauma from removal. Roughly one-third of U.S. foster placements are kinship, with significant state variation.
