The FDZ-DZA is accredited by the Council for Social and Economic Data (RatSWD). All accredited FDZs provide a sustainable and advanced research data infrastructure, offering free or low-cost access to a wide range of research data. You can find an overview of all research data centers in Germany and search for relevant data for your research questions on the RatSWD website.
The RatSWD also has a complaints office where unresolved issues regarding data usage in connection with an FDZ (including the FDZ-DZA) can be reported. For details about the complaints office and a contact form, please visit the RatSWD website.
