CID was an international network of researchers from fourteen European countries, financed by the European Science Foundation (ESF) and directed by Jan van Deth. The network accepted an extensive common core questionnaire on questions concerning social and political participation, small democracy, social capital, and citizen virtues. Identical population surveyswere conducted by all participating countries in the course of 2000 and 2001. The network also decided to conduct a comparative study on intermediary organisations. At the local level (MZES), the network decisions are realised through two separately financed projects.
