V-Party Dataset

Data source: Varieties of Democracy (V-Dem) Project

V-Party provides expert-coded assessments of party organization and identity for most parties in most countries over 1970-2019. Using V-Dem methodology (Coppedge et al., 2020), in January 2020, 665 experts rated the policy positions and organizational capacity of political parties across elections in a given country. Specifically, as a general rule, experts coded data for all parties that reached more than 5% of the vote share at a given election. The expert-coded data are aggregated using V-Dem’s Bayesian Item Response Theory measurement model (Pemstein et al., 2020). The result is data on 1,955 political parties across 1,560 elections in 169 countries; in total 6,330 party-election year units. Typically, at least 4 coders provided their assessment per observation.
