Danish Adoption Registry
The Danish Adoption Register was established in 1963 to 1964 to explore the genetic and environmental contribution to familial aggregation of schizophrenia in Denmark. The register encompasses information on all 14,425 non-familial adoptions of Danish children legally granted in Denmark in 1924 to 1947. It includes the names and dates of birth of each adoptee and his or her biological and adoptive parents, the date of transfer to adoptive parents, and the date of formal adoption. The basis of the register was the original records on all adoptions, familial as well as nonfamilial, kept in the Danish Ministry of Justice.
