This paper uses a new dataset on child-adoption matching to estimate the preferences of potential adoptive parents over US-born and unborn children relinquished for adoption. We identify significant preferences favoring girls and against African American children put up for adoption. These attitudes vary in magnitudes across different adoptive parents-heterosexual, same-sex couples, and single women. We consider the effects of excluding single women and same-sex couples from the process, and find that this would substantially reduce the overall number of adopted children. (JEL C78, J13, J15, J16).
