TY - UNPD A1 - Kreyenfeld, Michaela A1 - Kubisch, Olga T1 - Data Documentation Germany: Documentation for the Human Fertility Base N2 - The Human Fertility Database (HFD) is a joint project of the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany and the Vienna Institute of Demography (VID) in Vienna, Austria, based at MPIDR. We seek to provide free and user-friendly access to detailed and high-quality data on period and cohort fertility and thus to facilitate research on changes and inter-country differences in fertility in the past and in the modern era. The HFD is entirely based on official vital statistics and places a great emphasis on data checking and documentation and on warranting data comparability across time and countries by means of uniform methodology Y1 - 2014 UR - https://opus4.kobv.de/opus4-hsog/frontdoor/index/index/docId/895 PB - Max-Planck-Institut für demografische Forschung CY - Rostock ER -
