Reflecting the fact they usually get first preference concerning an adoption, adoption statistics suggest grandparents are the chief adopters of relatives in the United States today. 75% of homes of children owned by non-parent relatives are owned by grandparents.

Close to a quarter of all temporary or permanent placements involved relatives serving as foster parents for children in the absence of their birth parents.

Changes across time are reflected by changes in the family structure and the growing American population, while racially-oriented deviations may be related to the fairly heavy presence of minorities in the child welfare system.
