The first release of the OKiN codebook is available here.
For this project, a new multi-actor survey will be carried out among adults (ages 25-45) in the Netherlands, with the assistance of Statistics Netherlands (CBS). One of the unique features of these data is the oversampling of primary respondents who were not living with both of their biological parents at age 15. Furthermore, multiple parental figures will be approached for participation in the survey (i.e., secondary respondents) who will, in turn, report on their relations with multiple children. These characteristics of the survey will ensure a large enough sample of adults with complex family relationships and will give us the opportunity to examine solidarity and reproduction between multiple parents per child and / or multiple children per parent.
The name of the survey is Ouders en kinderen in Nederland (OKiN; Parents and children in the Netherlands). More information for participants can be found on the CBS website by clicking here.
