This dataset provides data on electoral volatility and its internal components in the elections for the European Parliament (EP) in all European Union (EU) countries since 1979 or the date of their accession to the Union. It also provides data about electoral volatility for both the class bloc and the demarcation bloc. This dataset will be regularly updated so as to include the next rounds of the European Parliament elections.

Electoral volatility in the European Parliament, caused by vote switching between parties that enter or exit from the party system caused by vote switching between existing parties, namely parties receiving at least 1% of the national share in both elections under scrutiny.
More about this variableNet change in the aggregate vote share for all parties included in the Class Bloc. For the definition of the class bloc and the identification of parties included in such bloc, the author relies on Bartolini and Mair (1990) and Bartolini (1983; 2000). This includes 'those parties which are the historical product of the structuring of the working-class movement' (Bartolini and Mair 1990 [2007], 46). Full list of parties in the class bloc can be found in the original codebook.
More about this variableNet change in the aggregate vote share for all parties included in the Demarcation Bloc. Those political parties that defend anti-EU, anti-immigration and economically protectionist policies are included in the demarcation bloc. Full list of parties in the demarcation bloc can be found in the original codebook.
More about this variableElectoral volatility in the European Parliament, caused by vote switching between parties falling below 1% of the national share in both the elections at time t and t+1. It is important to clarify that this category is not computed by aggregating the scores of each party falling below 1% and then comparing the overall sum at time t and t+1. Conversely, each party's volatility is counted separately - up to a specification of 0.1% - and then added to the calculation of evep_othv. This choice has been made to avoid underestimation of Total Volatility but at the same time to maintain a distinction between parties above 1% and parties below 1% for the calculation of the two components of evep_regv and evep_altv.
More about this variableElectoral volatility in the European Parliament, caused by vote switching between parties that enter or exit from the party system. A party is considered as entering the party system where it receives at least 1% of the national share in election at time t+1 (while it received less than 1% in election at time t). Conversely, a party is considered as exiting the part system where it receives less than 1% in election at time t+1 (while it received at least 1% in election at time t).
More about this variableTotal electoral volatility in the party system, given by the sum of the previous measures: evep_regv + evep_altv + evep_othv = evep_tv.
