PASSDA collects, analyses, and archives data on social and political attitudes and behaviours, for the use of the entire research community. It articulates the Portuguese components of two European research infrastructures — European Social Survey-ERIC and CESSDA-ERIC — and is part of the Portuguese Roadmap of Research Infrastructures.
The Portuguese Archive of Social Information (APIS) is a scientific infrastructure acting on the domain of preservation and dissemination of social science data. Based at Instituto de Ciências Sociais, University of Lisbon, the archive works towards the acquisition and sharing of digital data for the purposes of public consultation, secondary analysis and pedagogical use. The archive comprises a range of datasets provided by research projects of the national scientific community.
