Family-based foster care is generally preferred to other forms of out of home care. Foster care is intended to be a short-term solution until a permanent placement can be made. In most states, the primary objective is to reconcile children with the biological parents. However, if the parents are unable or unwilling to care for the child, or if the child is an orphan, then the first choice of adoptive parents is a relative such as an aunt, uncle or grandparent, known as kinship care. Most kinship care is done informally, without the involvement of a court or public organization. However, in the United States, formal kinship care is increasingly common. In 2012, a quarter of all children in formal foster care were placed with relatives instead of being placed into the system.
