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 is particularly true when it comes to the regional level.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). Central categories such as NUTS and LAU are explained and discussed. In addition, typical examples of socio-economic cross-border and multi-level studies highlight the power of a regionalized European perspective. Furthermore, information about special tools for such type of analysis is included in the volume.
