States: A

How Letter A States Compare in the Foster Care System

The 4 states catalogued under the letter A together account for 19,374 children currently in foster care, an average of roughly 4,844 children per state in this group. This is a sizable cluster within the AFCARS reporting set, and pages here share a blended reunification rate of 45.7%, near the national midpoint. Arizona carries the largest share within this letter group, with 8,234 children in care — a volume that can reflect state population, child-welfare reporting rigor, or the concentration of high-need communities rather than any single policy outcome.

Foster-care metrics at a letter-group level are most useful as a navigation aid, not a ranking: children's experiences are shaped by state statutes, court capacity, kinship placement availability, and the prevalence of reunification services. Two neighboring states can report similar in-care populations but very different aging-out, reunification, or kinship-care outcomes. When comparing across this cluster, we recommend pairing the in-care count with reunification rate and aging-out rate together — any single metric in isolation can mislead.
