About PDYi

The Political Data Yearbook Interactive (PDYi) published the data held within the Political Data Yearbook (PDY), published by Cambridge University Press on behalf of the European Consortium for Political Research (ECPR).

PDY, collects election results, national referenda, changes in government, and institutional reforms in 37 countries including all the EU member states. In addition, recognised experts on the politics of each country provide commentary on these events, as well as on the principal issues in national politics.

PDYi is a unique data source building on the PDY content, which is freely available to anyone. It provides the data in a fully searchable and downloadable format. Users can view different types of data in graphical format, customise by adjusting time settings or selecting parties to view, and download full datasets (with footnotes), making it a highly flexible and indispensable resource.
