UniData, thanks to the experience gained by ADPSS-Sociodata, has been the Italian member of CESSDA (Consortium of European Social Science Data Archives), the most important system of acquisition, archiving and distribution of data for social sciences. It connects data archives of twenty-three countries.
A very important archive connected with CESSDA is the GESIS – Leibniz Institute for the Social Sciences, with which UniData is continuing an intense collaboration. UniData also participates to IFDO (International Federation of Data Organizations), in which it sustains the chairmanship since the year of its foundation, in 1983.
Finally, UniData is a member of ICPSR (Inter-university Consortium for Political and Social Research), one of the most important data archive for world social sciences, that is located in the University of Michigan. In particular UniData is the Italian Official Representative, because it is part of Italian University network that participate to ICPSR.
