CDSP's "Banque de données"

Major Socio-Political Surveys

The CDSP Banque de données contains a large number of surveys in the field of socio-political research, as well as quantitative and qualitative surveys covering a wide range of topics, including science, the environment, health, sexuality, cultural practices and intergenerational relations.

Organised into different thematic collections, these survey data can be easily explored.

The Données de recherche Collection

Several major survey series are available, including Electoral Surveys produced since 1958, the Enquêtes interrégionales des phénomènes politiques conducted by the Observatoire Interrégional du Politique, and data from the Agoramétrie programme, which tracked public opinion on nuclear power for more than 10 years.

The ELIPSS Collection

Around 150 surveys have been produced by the CDSP since 2012, including series designed to track and analyse changes in the behaviours and opinions of the French population in relation to elections, digital practices, and during the Covid-19 pandemic.

The Historical Election Results Collection

Freely accessible, this collection makes it possible to analyse different types of elections since 1988, including cantonal elections, European elections, legislative elections, municipal elections, presidential elections, regional elections and referendums.

Since 2025, the collection has been expanded with the French Election Results Database, which provides election results using an original colour-coding system.

The Qualitative Data Collection

Most of these references come from the beQuali project, which has been incorporated into the CDSP Banque de données. The studies were conducted using qualitative methods – observations, interviews, focus groups, etc. – and cover topics such as education, couple formation and Europe.

Teaching Datasets

The CDSP has recently produced simplified, open-access teaching datasets to facilitate the teaching and learning of quantitative methods.

Facilitating Data Reuse

The variables in the quantitative datasets held by the CDSP Banque de données are documented in detail – including filters, recoding techniques, frequency distributions and instructions to interviewers – in accordance with current international standards. The datasets are formatted to facilitate their reuse for further research.

Notable Publications Based on Data Reuse

In his book Controlling the Electoral Marketplace, Joost van Spanje (University of Amsterdam) reuses historical Electoral Survey data to examine how established political parties respond to the emergence of parties at the extremes of the political spectrum across a range of democracies.

Sarah Schneider-Strawczynski (Paris School of Economics) and Jérôme Valette (Université Paris 1 Panthéon-Sorbonne) reuse the thirteen waves of the Dynamiques de mobilisation series to compare changes over time in individual perceptions of immigration in their article Media Coverage of Immigration and the Polarization of Attitudes.

A Trusted Banque de données

Thanks to the quality of its documentation procedures, data dissemination and data preservation, the CDSP Banque de données was awarded the prestigious CoreTrustSeal certification in August 2023. In addition, the Data College of the French Committee for Open Science has included the CDSP Banque de données in its list of trusted repositories.

This certification guarantees that the CDSP has established a trusted data repository that meets CoreTrustSeal requirements for data preservation, security and quality, which are also consistent with the requirements of France’s National Plan for Open Science.

In practice:

• How can I request data?
• How can I deposit data?
• Where can I browse questions from questionnaire-based surveys?
