For this project, a new multi-actor survey was carried out among Dutch adults (ages 25-45), 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, both biological parents (and if applicable, their current partners) of the primary respondents were approached for participation. They, in turn, reported on their relations with multiple children. The final realized sample sizes are 6,485 primary respondents (71.9% from non-intact in youth households) and 9,325 (step)parent figures. A detailed codebook can be found by clicking here and the data are publicly available via DANS. First descriptive findings about the data can be found in the following ESR publication: “A Multi-Actor Study of Adult Children and Their Parents in Complex Families: Design and Content of the OKiN Survey“.
In 2020 a follow-up to the OKiN survey (acronym OKiN2020) was carried out, where the adult children from the original sample were re-approached. A total of 3,070 people participated (response rate of 59%). The new survey included a selection of questions from the 2017 OKiN survey, as well as, newly designed questions on parent-parent relationships, sibling relationships, and grandparents. Respondents were interviewed using Computer-Assisted Web Interviewing. The codebook for that wave can be found here.
