Max Planck Institute for Demographic Research

We study the structure and dynamics of populations and explore issues of political relevance, such as aging, fertility, and the redistribution of work over the life course, as well as digitization and the use of new data sources for the estimation of migration flows.

The scientists offer recommendations to counteract the social implications of this trend. More
