During the civil rights movement, a few regional adoption agencies began challenging race-matching in adoptions by placing some African-American children in non-minority households. Organizations, including the Open Door Society and the Council on Adoptable Children, likewise began publicize the needs of these orphans of color. However, only small amounts of African-American children were ever adopted by white parents, reaching their high around 1970. This also spurred rapid growth in international adoptions, the numbers more than tripled from 733 cases in 1968 to 2,574 cases in 1971, where large numbers of Asian children were adopted by Caucasian American families. (There are now about 6,500 cases a year.) However, in 1972, the National Association of Black Social Workers formally condemned interracial adoption, citing that adoptees were at risk for developing a poor racial identity due to lack of contact with role models of the same race. In the 1990s the placement of black children into non-black homes virtually came to a complete stop.
