Europe is getting closer. So are European social sciences. However, this is easier done in theory development and central research questions. When it comes to data the mutual understanding is far from perfect, due to a lack of knowledge about the data bases of the respective countries and the EU in general. This volume will help to improve the insight into the rich stock of European datasets which cover any kind of regional information. Many institutions ranging from statistical offices to more academic research centres and commercial enterprises report their offerings with special emphasis on the regional level (e.g. European Community Household Panel, European Social Survey, Labour Force Survey).
