From the 2004 Child Welfare Information Gateway report:

Number of U.S. Adoptions

In 2000 and 2001, about 127,000 children were adopted annually in the United States. Since 1987, the number of adoptions annually has remained relatively constant, ranging from 118,000 to 127,000.

Breaking Down The Numbers

The source of adoptions is no longer dominated by kinship adoptions and private agency adoptions. Public agency and intercountry adoptions now account for more than half of all adoptions.

Child Welfare

Adoptions through publicly funded child welfare agencies accounted for two-fifths of all adoptions. More than 50,000 public agency adoptions in each year (2000 and 2001) accounted for about 40 percent of adoptions, up from 18 percent in 1992 for those 36 States that reported public agency adoptions in 1992 (Flango & Flango, 1995).

Intercountry Adoptions

Intercountry adoptions accounted for more than 15 percent of all adoptions. Intercountry adoptions increased from 5 percent to 15 percent of adoptions in the United States between 1992 and 2001 (U.S. Department of State).

Other

The other two-fifths of adoptions are primarily private agency, kinship, or tribal adoptions. With the available data, it is not possible to separate figures within this group, although the percentages of all adoptions in that group as a whole have decreased. In 1992, for example, stepparent adoptions (a form of kinship adoption) alone accounted for two-fifths (42 percent) of all adoptions.
