CESSDA provides large-scale, integrated and sustainable data services to the social sciences. It brings together social science data archives across Europe, with the aim of promoting the results of social science research and supporting national and international research and cooperation.
Since its establishment in 1976, CESSDA served as an informal umbrella organisation for European national social science data archives. CESSDA has been on the ESFRI Roadmap since 2006. It became a legal institution (CESSDA AS) in 2013 and then an ERIC (European Research Infrastructure Consortium) in 2017. Norway is hosting CESSDA, and the main office is located in Bergen.
