The Observatory of Quality of Democracy (OQD) is a permanent research program of the Institute of Social Sciences that promotes and organizes projects focused on the diverse characteristics, functioning and quality of democratic regimes.

Created in 2010, as the Barometer of Quality of Democracy, the OQD aspires to be a repository of relevant information on the issues surrounding democracy, in both Portugal and other Portuguese-speaking countries. In this sense, the OQD aims to be a space for the production and dissemination of knowledge and to become a reference at the national and international levels.
