Integrated Party Organization Data on 311 Parties from 22 Postwar Countries

311 political parties from 22 countries are documented in this integrated dataset covering the postwar period. It combines multiple cross-national data sources on party organization, performance, positions, and electoral systems into a single resource. The dataset was compiled by Nathalie Schumacher Giger of the University of Geneva to aid comparative research.

Use Cases

• Modeling relationships between party organization and electoral performance based on integrated metrics.
• Analyzing cross-national trends in party positions over the postwar period.

Strengths

• Integrates data from several distinct cross-national collection projects, potentially reducing data fragmentation.
• Covers 311 parties across 22 countries, providing a multi-country scope.
• Includes unique party identifiers to facilitate linkage and longitudinal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
