PostDoc Family Complexity

Project description

This project analyzes the demography of family complexity with a novel set of questions and a unique mix of contemporary survey data and historical register data. Examples of research questions that can be studied are: (a) What are the demographic and socioeconomic determinants of divorce, widowhood, early single parenthood, and stepfamily formation? (b) What are the consequences of divorce, widowhood, and stepfamily living for children, in particular for their own life course transitions and their socioeconomic achievement? (c) How is the process of intergenerational transmission affected by parents who leave the household and stepparents who enter the household? (d) How do the effects of parental divorce and (early) parental death on children compare? (e) How do the effects of family instability on children in current times compare to effects of instability in the early 20th century?

Data that will be used for the contemporary part of the sample come from the OKiN survey, which is a large-scale survey among adult children aged 25-45 conducted in 2017 ( as part of the PI’s ERC project on family complexity.

For the historical part of the sample, data from the Historical Sample of the Netherlands (HSN) will be used in conjunction with the LINKS data set (

The mix of contemporary and historical data used in the project depends on the skills and preferences of the candidate.
