Description

    This dataset identifies and lists all the new parties emerged in Western Europe since 1945 and provides data about party system innovation, defined as the aggregate level of ‘newness’ recorded in a party system at a given election. Data are based on parliamentary elections (lower house) in 20 Western European countries since 1945. This dataset covers the entire universe of Western European elections held after World War II under democratic regimes. Data for Greece, Portugal and  Spain  have  been  collected  after their  democratizations  in  the  1970s.

    This dataset will be regularly updated so as to include latest elections.
