About the journal
From January 2026,
PDY will be published fully open access in partnership with
Cambridge University Press.
Political Data Yearbook (PDY) contains comprehensive and authoritative data and analysis of electoral results, national referenda, changes in government, and institutional reforms for a range of countries, within and beyond the EU (all EU member states, plus Australia, Canada, Iceland, Israel, Japan, New Zealand, Norway, Switzerland, the United Kingdom and the United States). Recognised experts on the politics of each country provide commentary on these events, as well as on the principal issues in national politics during the year.
Its online version, PDY interactive (PDYi) is a unique data source building on the PDY content, which is freely available to the profession. PDYi 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.
