In Romania, as in other former communist countries, there has long been a deficit of information about social research and its data. In light of the growing need for high-quality data, which are a pre-condition for effective social policies, solutions to address the deficit are currently being sought both nationally and internationally. The article summarises the recent establishment of the Romanian Social Data Archive, which is supported by the Institute for Quality of Life Research (an institute of the Romanian Academy of Sciences) and by the Faculty of Sociology and Social Work of the University of Bucharest and points to the main technical and legal challenges that it faces. Indications about collaborative activities are also provided, pointing to the common problems raised by social science data in Eastern Europe and the considerable scope for cooperation in addressing them.
