Electoral and Parliamentary Data

 


Campaign finance data (DIME/Stanford)

The Database on Ideology, Money in Politics and Elections (DIME), developed at Stanford University, includes records "for over 100 million political contributions made by individuals and organizations to [U.S.] local, state, and federal elections spanning a period from 1979 to 2012." Data files and documentation are available at this link.

 


Chapel Hill Expert Surveys (CHES) 

Chapel Hill Expert Surveys provide estimates of political party positions on "European integration, ideology and policy issues for national parties in a variety of European countries." CHES provides a 1999-2014 trend file, and individual waves for 1999, 2002, 2006, 2010 and 2014.

 


Comparative Campaign Dynamics Datasets

Comparative Campaign Dynamics Datasets - maintained by researchers at the University of Mannheim, Washington University, St. Louis and the University of Texas, Austin - provide "information on ideological cohesion and ambiguity of party positions along with information on framing effects by competing parties and the media. The data covers the policy standpoints parties and their representatives have communicated in the media along with valence-related statements, such as references to competence or integrity." Ten countries are covered: Czech Republic, Denmark, Germany, Hungary, Netherlands, Poland, Portugal, Spain, Sweden and United Kingdom. Full details are on this project page.

 


Comparative Study of Electoral Systems (CSES)

CSES is a collaborative programme of cross-national electoral research conducted in 54 states over four modules; 1996-2016. The project is coordinated by the Center for Political Studies and GESIS. CSES is composed of three parts: "First, a common module of public opinion survey questions is included in each participant country's post-election study. These 'micro' level data include vote choice, candidate and party evaluations, current and retrospective economic evaluations, evaluation of the electoral system itself, in addition to standardized sociodemographic measures. Second, district level data are reported for each respondent, including electoral returns, turnout, and the number of candidates. Finally, system or 'macro' level data report aggregate electoral returns, electoral rules and formulas, and regime characteristics."

 


Constituency-Level Elections Archive (CLEA)

The Constituency-Level Elections Archive (CLEA) contains results of 1900 elections from 168 countries worldwide. Register online to access the data in zipped files, with PDF documentation. The database provides results "at the constituency level for lower house legislative elections from around the world." First-time users should register on this CLEA page. The 13th wave was released in 2019.

 


Dataset of Electoral Volatility and its Internal Components in Western Europe

The Dataset of Electoral Volatility and its Internal Components in Western Europe - covering the period 1945 to 2015 - was launched in September 2015 by researchers at the CISE - Italian Center for Electoral Studies LUISS 'Guido Carli' Rome and University of Florence.

The dataset provides observations on electoral volatility and internal components of 'regeneration' (i.e. electoral volatility caused by vote switching between parties that enter or exit from the system) and 'alteration' (i.e. electoral volatility caused by vote switching between existing parties) in parliamentary elections (lower houses) in 19 countries of post-war Western Europe.

The dataset (Excel format) and codebook (PDF) may be downloaded via the LUISS platform and the GESIS social sciences archive.


Dataset of Electoral Volatility in the European Parliament elections since 1979

Dataset of Electoral Volatility in the European Parliament elections since 1979 provides data on "electoral volatility and its internal components in the elections for the European Parliament (EP) in all European Union (EU) countries since 1979 or the date of their accession to the Union. It also provides data about electoral volatility for both the class bloc and the demarcation bloc." The dataset maintained by researchers at CISE, the Italian Center for Electoral Studies LUISS 'Guido Carli', Rome.

 


Dataset of New Parties and Party System Innovation in Western Europe since 1945

The Dataset of New Parties and Party System Innovation in Western Europe since 1945 "identifies and lists all the new parties emerged in Western Europe since 1945 and provides data about party system innovation, defined as the aggregate level of ‘newness’ recorded in a party system at a given election. Data are based on parliamentary elections (lower house) in 20 Western European countries since 1945. This dataset covers the entire universe of Western European elections held after World War II under democratic regimes. Data for Greece, Portugal and  Spain  have  been  collected  after their  democratizations  in  the  1970s."  The dataset - updated in May 2018 - is maintained by the Italian Center for Electoral Studies LUISS 'Guido Carli' Rome.

 


Electoral data archive (ICPSR)

EUI members have access to diverse international election data from the ICPSR data archive. The Inter-university Consortium for Political and Social Research (ICPSR) archive is a large-scale repository of approximately 500,000 files, hosted by the University of Michigan. Use the ICPSR catalogue to locate study numbers. Downloading is by the Information Specialist: send the study number(s) and data format required, to [email protected]

 


EUDO data on European democracy (EUI)

EUDO is a project under the overall direction of Prof. Alexander Trechsel (University of Lucerne and EUI).

In advance of the European Parliament elections of May 2014, EUDO launched euandi - an online voting advice application. The project - successor to the 2009 EU Profiler party positions and user profiles project - was undertaken by Prof. Trechsel (EUI); Prof. Lorenzo De Sio (LUISS University, Rome) and Diego Garzia (EUI) in cooperation with Harvard University.

  • Party data from the 2014 euandi project is also accessible via the the GESIS archive, Study ZA5917
  • Voter profile data (anonymised) from the euandi project is also accessible as Study ZA5970
  • The euandi data codebook is at this link.

EUDO data are generated by four project observatories: (i) The Observatory on Public Opinion, Political Elites and the Media (ii) The Observatory on Political Parties and Representation (iii) The Observatory on Institutional Change and Reform and (iv) The Observatory on Citizenship.

 


European Election Database (NSSDS)

The European Election Database provides observations on over 400 elections and referenda in 35 countries since 1990. The database is elaborated by the Norwegian Social Science Data Service which collates data from national authorities and statistical agencies. Interactive maps, graphs and tables facilitate pan-European comparative research on parliamentary elections, presidential elections, European Parliamentary elections and EU-related referenda. A geo-chronological matrix of electoral events is on this EED page. The NSD software support page is at this link.

 


European Election Studies (EES/GESIS)

The GESIS social science data archive provides access to European Election Studies generated by the European Election Study (EES) Research Group, including election-related special Eurobarometer surveys since 1979. European Election Studies cover participation and voting behaviour in European Parliament elections and include topics such as "the evolution of a political community and public sphere in the European Union, citizens' perceptions of and preferences about the EU political regime, and the evaluation its political performance."
