The PartyEurope dataset links national and regional parties to their respective European political party and, in case they are represented in the European Parliament, to the parliamentary group. The dataset can be used for comparisons within and between party families. (1) affiliations of parties as of April 2017, covering parties within the jurisdiction of the European Union (2017). In a time where parties and party alliances emerge and disappear, and European parliamentary groups can be reshuffled, this dataset can only provide a snapshot. (2) including 462 national and regional parties in 28 European member states, of which 284 are represented on the national level and 206 in the European Parliament. (3) provides party identifiers of Comparative Manifesto Project (CMP) and Chapel Hill Expert Survey (CHES) to easily link data of different datasets. Definition of European Parties according to EU Regulation No 1141/2014 on the statute and funding of European political parties and European political Foundations, see also the European Parliament webpage.

Please note: As of now, membership to European parties is not coherently regulated, therefore the following membership conditions apply:
- Cross-membership of national parties: national parties can be members of more than one European political party as recognised by the European Parliament.
- Members of the European Parliament shall be considered as member of only one European political party, which is not necessarily the European party of its national party affiliation (Art 17, 3)
- Individual membership of Members of the European Parliament to a European Political party can exist. Membership allegiance of MEPs can change with each funding year which affects the number of MEPs affiliated with a European political party and its finances (Art 19, 2)
For this dataset, the calculation of the number of MEPs is based on the party affiliation approach, i.e. the membership of the national party of a MEP to a European political party. This is due to a lack of data on individual members and the fluctuation of allegiances with every financial year. The party affiliation approach is likely to overestimate the number of MEPs for European parties where national parties do not demand their MEPs to align with the European party, and underestimates the number of MEPs for European parties that benefit from membership subscriptions of MEPs from non-member national parties or individual MEPs. However, this approach is considered useful for estimating the levels of MEP membership for the whole legislative term. National parties without affiliation to a European political party but representation in EP are denoted "n.a.", otherwise "-".
