Historical Election Trends for Academic Research & Teaching

This data is specifically optimized for universities, colleges, and research institutions that require precise political sentiment data for empirical research, political science analyses, or academic instruction.

This dataset provides the historical evolution of PolitPro's Election Trends for over 70 parliaments across Europe. The harmonized time series extend back to at least 2020, depending on the specific parliament, and are updated weekly, with a stable snapshot 'frozen' monthly.

The PolitPro Election Trend aggregates poll results from all relevant institutes into a weighted average. More recent polls are weighted more heavily than older ones, and the historical predictive accuracy of the institutes is also factored in. The result is a statistically robust trend line that smooths out short-term outliers and reveals real political dynamics over time.

The data is provided as a CSV download in a scientifically standardized long format. This format enables immediate import and processing in popular statistical software such as R, Python (Pandas), Stata, or SPSS.

Where available, all datasets include official PartyFacts project IDs. This enables seamless integration of PolitPro Election Trends with other international research databases (e.g., ParlGov, CLEA, or CHES) without the need for manual mapping.

To ensure maximum comparability across various institutes and national borders, raw data undergoes standardization: We convert published poll values to reflect the actual electorate with explicit voting intention, then normalize the results to 100%. The final day of each respective survey period consistently serves as the temporal anchor point.

PolitPro is recognized as one of the most reliable sources for European election trends, regularly utilized by international media and political institutions. All data undergoes a rigorous multi-stage quality assurance process, combining algorithmic analysis, AI-powered validation, and manual review to rectify any methodological inconsistencies in primary sources. All data is provided without warranty.

Yes, absolutely. At the beginning of each month, we create an immutable snapshot of the complete historical data. This serves as a stable, permanently reproducible reference for your academic research. Once a snapshot is published, it remains unchanged thereafter. Should polling institutes release retroactive survey data or implement methodological updates, these will be incorporated into the subsequent monthly snapshot. Existing snapshots remain unaffected, precisely replicable, and fully citable.

Each monthly snapshot is assigned a unique version number to ensure full replicability. For your publications or academic papers, a standardized citation example is: PolitPro: European Polling Data and Election Trends, Snapshot , politpro.eu.

The data is approved for academic use in research and teaching. Analyses and aggregated graphics may be published in scholarly papers and theses. Commercial use, along with the dissemination or republication of the complete raw datasets to third parties, is strictly prohibited.

Independently collecting, cleaning, weighting, and normalizing survey data from over 30 European countries can consume months of valuable research resources. PolitPro eliminates this error-prone preparatory work for you. You receive a ready-to-use, quality-assured dataset – immediately available for analysis, teaching, and academic theses.

PolitPro is Europe's premier platform for European election trends and political polling data, aggregating and weighting poll results from over 70 parliaments. Our data is utilized by international media, political institutions, and research organizations alike.
