The Federal Institute for Population Research (BiB), together with the Leibniz Institute for Social Sciences GESIS and the University of Cologne, is creating a new research basis for a better understanding of changes in family and demographic development. The project is funded by the German Federal Ministry of Education and Research (BMBF) with 12.5 million euros until 2024 and if the evaluation is positive the German Federal Ministry of the Interior, Building and Community (BMI) will ensure that funding is continued.
