The Center for Studies on Public Opinion—better known by its Portuguese acronym CESOP—is a center for interdisciplinary research established at the State University of Campinas since 1992. Its central objective is the development of scientific research in the field of political and social behavior; in this sense, the CESOP seeks both to consolidate a structure for organization, consultation, and dissemination of survey data, and to promote combined initiatives in teaching, research, and human resources training in this area.
