This dataset provides data on ideological polarization in Western Europe. It is based on parties’ left-right placement provided by several expert surveys. Then, it uses Dalton’s polarization index (2008) to calculate the polarization score in terms of votes and seats for each election. The dataset covers 20 Western European countries since 1945, for a total of 398 parliamentary elections and legislatures (Lower House).
The dataset is based on parties’ left-right placement provided by a series of comparative and widely-recognized expert surveys that allow for extended temporal coverage and reliable cross-country and cross-time comparisons.
