The PopuList offers academics and journalists an overview of populist, far right, far left and Eurosceptic parties in Europe since 1998. The PopuList is supported by the Amsterdam Institute for Social Science Research, The Guardian, and the ECPR Standing Group on Extremism & Democracy.

The PopuList is the result of close cooperation between academics and journalists, initiated by The Guardian. The list consists of European parties that can be classified as populist, far right, far left and/or Eurosceptic, and obtained at least 2% of the vote in at least one national parliamentary election since 1998. The list has been thoroughly peer-reviewed by more than 30 academics. See here for how The Guardian has used the list.
