The German Centre for Integration and Migration Research (DeZIM) is a political and scientific initiative in order to strengthen excellent and internationally visible integration and migration research in Germany. The Research Data Centre DeZIM.fdz gives researchers the opportunity to access data collected within the scope of research projects of the DeZIM institute itself and of the institutes belonging to the DeZIM research community. Besides providing access to these data, the DeZIM.fdz also offers a comprehensive information database. This database allows for research on migration and integration studies archived in the DeZIM.fdz as well as in other research data centres. Moreover, the DeZIM.fdz offers support to data users and gives advice on selected methodological issues.
