10% to 12% of adoptions of children aged three and older disrupt. (Barth and Berry, 1990)

Placements of older children and children with histories of previous placements and longer stays in the foster care system are more likely to disrupt (Stolley, 1993)
The disruption rate increases as the age of the child at the time of adoption increases. (Boyne et al., 1984; Barth and Berry, 1988)
The overall decrease in disruption percentages in 1988 from 1984 can be traced to the introduction of post-adoption services, an important factor in containing the number of adoption disruptions. (Barth and Berry, 1988)
