This memo estimates the impact on children and the cost to the State of Florida of the current prohibition on adoption by gay, lesbian, and bisexual (GLB) individuals and same-sex couples. We use data about the number of children adopted each year as a way to estimate the number of GLB individuals and same-sex couples who would be likely to serve as adoptive parents if the ban were not in place. Prohibiting GLB individuals and same-sex couples from adopting means that 165 children must remain in foster care or must have alternative adoptive homes recruited for them. As a result, we estimate that the ban costs the State of Florida over $2.5 million in per year. As explained below, this estimate is conservative since some likely additional costs are difficult to quantify. In addition, because of the current prohibition on GLB individuals and same-sex couples adopting children in Florida, it is possible that more GLB individuals and same-sex couples would be interested in adopting if the ban were lifted. We estimate that if the ban were lifted, both adoption and foster care by GLB individuals and same-sex couples would increase to the average United States level, leading to 219 children being adopted, and saving the State of Florida $3.4 million dollars in the first year.
