Print and online versions of the European Fertility Datasheet 2015 were officially launched on December 2, 2015 at the conference on Education and Reproduction in Low-Fertility Settings in Vienna. Through a combination of data for all countries of Europe and for broader European regions, maps, tables, graphs and featured thematic boxes combining text and graphics, the datasheet provides an in-depth look at European fertility. The online version provides expanded coverage, including additional maps, ranking charts as well as details about data sources and definitions. It also allows the users to download all the data. The datasheet was supported from the EURREP project budget and was prepared in collaboration of five EURREP researchers with two researchers affiliated with the Wittgenstein Centre for Demography and Global Human Capital.
