Estimating the annual domestic adoption rate and lifetime incidence of infant relinquishment in the United States

Objectives: Estimating the rate of infant relinquishment for adoption in the United States (U.S.) can inform understandings of pregnancy decision-making and adoption practice. Yet, private domestic adoptions are not systematically tracked. Most methods of estimating adoptions rely on nonmarital birth rates, despite the changing social context of nonmarital births. This analysis provides updated estimates of the rate of infant relinquishment for private domestic adoption in the United States. Study Design: Using data from National Council for Adoption, Centers for Disease Control, and Guttmacher Institute, I compiled annual estimates for the number and rates of births, abortions, and adoptions; calculated annual domestic infant adoption rates among all women and unmarried women of reproductive age; estimated the number of adoptions as a proportion of marital and nonmarital births; and estimated the lifetime incidence of relinquishment for U.S. women. Results: Since 1982, the annual adoption rate per 10 0 0 U.S. women of reproductive age has been between 0.32 and 0.45, decreasing for the last 30 years. The most recent adoption rate translates to a lifetime relinquishment estimate of 0.9% of U.S. women. Based on patterns from 2002 to 2014, I estimate the current number of private domestic adoptions to be approximately 0.5% the annual number of births, or about 18,300 to 20,000 adoptions per year. Conclusions: Despite finding a higher estimate of private domestic adoptions per year than previous estimates, adoption relinquishment rates remain dramatically lower than birth (and thus parenting) and abortion rates in the U.S. Implications: National and state level information about annual adoptions is needed to inform policies regarding adoption, abortion, and support for families.
