European Network – IDAN

CASD is part of the International Data Access Network (IDAN) project, founded in 2018. The project is a collaboration between 6 Research Data Centres (RDCs) from France, Germany, The Netherlands and the United Kingdom to facilitate research use of controlled access data between these RDCs/countries.

In its first phase IDAN aims to enable researchers to work remotely on secure access data provided by partner countries from within each Research Data Centre with all access points in the same physical place (RDC/ Safe Room). For more information on the project’s progress and availability of access points and data, please see the project website.

Partnership CASD-IAB

Access to the data of the Institute for Employment Research (IAB) available via its secure Research Data Centre, FDZ

Following the signing of the agreement between CASD and IAB, access points were set up in their respective institutions in Palaiseau and Nuremberg in order to facilitate partnerships and comparative work using French and German data sources.

The access point recently installed at CASD in Palaiseau is today the only point of access in France for consulting German data on the topics of social security and employment at the same level of detail as the access via the IAB website.

At the same time, it is possible for German researchers wishing to work on French data covered by statistical confidentiality to access it directly via the CASD SD-Box at the IAB in Nuremberg.

To facilitate your research, a summary table mentioning possible comparisons of IAB and CASD data sources is now available on our website.

Whether or not you are a CASD user, you can now request access to IAB data to work from CASD. You will find all information regarding the data available on IAB’s website. The application for authorization is made by the German Federal Employment Agency. The data access conditions and the authorization procedure are described in the “on-site use” section of IAB’s website.

Working on the Data from CASD Headquarters

The cost of the access point is funded by CASD under the cooperation agreement with IAB, so access to German data is free. Please note that access to German data is not via the CASD SD-Box but via the equipment provided by IAB and installed for this purpose in our premises.
