Data Set on Partisan Polarization in European Countries Between 2002 and 2022

This data set includes two partisan polarization indices composed from European Social Survey data, named PPI(identifiers) and PPI(voters), according to Patkós (2023), using the EGOV dataset (Patkós & Plesz, 2021, 2022). According to Patkós (2023), partisan polarization indicates the extent to which the political life of a community can be described as a battle between two partisan sides. Based on this notion, it calculates partisan polarization based on respondents’ satisfaction with their national government, by comparing the average satisfaction of cabinet supporters (who evaluate the government as a part of their in-group) to the average satisfaction of opposition supporters (who evaluate the government as a part of their out-group) for each country case.
