The European NUTS-level election dataset: A tool to map European electoral geography.

Abstract

Datasets on subnational election results in Europe frequently do not match with regional statistics available for cross-national research, mainly because territorial statistical units change over time and do not map onto the national electoral districts. This hinders consistent comparative research across time. This research note introduces EU-NED, a new dataset on subnational election data that covers national and European parliamentary elections for European countries over the past 30years. EU-NED's major contribution is that it provides election results on disaggregated levels of the statistical territorial units used by Eurostat with an unprecedented consistency and temporospatial scope. Moreover, EU-NED is integrated with the Party Facts platform, allowing for a seamless integration of party-level data. Using EU-NED, we present first descriptive evidence on the European electoral geography and suggest avenues of how EU-NED can facilitate future comparative political science research in Europe.
