Research Group Fertility and Population Change

Research focus

The research group "Fertility and Population Change" studies fertility preferences, childlessness, union formation and dissolution, family changes and couple relations and their interconnections. It combines research based on individual- and aggregate-level data and puts a strong focus on education differences in family behaviours. The group also actively collects and disseminates data through several databases, including the Human Fertility Database (HFD, a collaboration with MPIDR in Rostock) and the Cohort Fertility and Education (CFE) database.
