All the international and national data resources are documented in both Lithuanian and English. Access to the data is provided via this Dataverse repository. LiDA curates most of the data collected conducting the most important international social surveys in Lithuania – the European Social Survey, European Values Studies, European Election Studies and the International Social Research Program. LiDA is hosted by the Centre for Data Analysis and Archiving of Kaunas University of Technology (data.ktu.edu).
