“Sweden has the highest per capita proportion of international adoptees in the world. In practice, this means that the vast majority of Swedes have personal experience of adoption. There is a good chance of having a relative, friend or neighbour who has adopted or is an adoptee. Adoption is an accepted and well-established way of forming a family in Sweden.”
