The aim of the EVS Pre-Releases is to make the current data of the European Values Study, which has been back in the field since September 2017, quickly available for research. They are lean products created by the research group at Tilburg University, the participating countries and the GESIS data archive. The data is based on the questions of the Master Questionnaire but does not yet include all harmonized and derived variables. The documentation provides information on the creation and processing of national data, but still in a compact format.
Another concern of EVS Pre-releases is to improve the quality of the data and its documentation. Information on errors or omissions in the data and the documentation is very welcome. Please report any problems in data and documentation to the EVS Data Service at GESIS, Cologne. We appreciate your help!
The first pre-release, which included 16 countries (Armenia, Bulgaria, Germany, Georgia, Iceland, Croatia, Netherlands, Austria, Poland, Russia, Switzerland, Slovak Republic, Slovenia, Spain, Czech Republic, Belarus) has been published in December 2018.
The second pre-release (published July 2019) includes data from 30 countries. Compared to the previous one, this version of the integrated dataset adds 14 new countries (Albania, Azerbaijan, Denmark, Estonia, Finland, France, Great Britain, Hungary, Italy, Lithuania, Norway, Romania, Serbia, Sweden) and data from the mixed -mode applied in 6 countries (Denmark, Finland, Germany, Iceland, Netherlands, Switzerland). The dataset inlcudes also further harmonized variables on education and occupation, and the first weight variables.
The third pre-release of the EVS 2017 includes data and documentation of altogether 35 participating countries. The release includes two integrated datasets: The EVS 2017 Integrated Dataset (ZA7500) contains data from about 55.200 respondents and 33 countries. The EVS 2017 Integrated Dataset – Matrix Design Data (ZA7502) includes data from about 10.500 respondents and the four countries (DE IS CH NL) that applied the matrix design.
Integrated and individual national datasets of EVS 2017 are accessible through the GESIS Search at GESIS- Leibniz Institute for the Social Sciences.
The Full Data Release will contain almost all countries participating in the EVS, and also other harmonized variables, such as: on education and occupational status as well as weighting variables, and be well documented. In addition, it will form the basis for the EVS Longitudinal Data File 1981-2017 and will assist researchers in longitudinal analysis and the inclusion of the extensive body of data from the World Values Survey. The European Values Study and the World Values Survey agreed to collaborate in carrying out the 2017 values survey in Europe. In line with this agreement, both organizations coordinated the questionnaire’s design and the overlap in the two questionnaires is about 60%. In all European countries, the EVS questionnaire is applied, and data collection is coordinated by EVS according to the strict methodological guidelines prepared by EVS Methodology Group that are specifically adapted to the European context.
Due to the outbreak of coronavirus, the Full Data Release of EVS 2017 has been postponed to early October 2020. However, to make the current data available for research, a third pre-release will be available on 27 May 2020.
This EVS pre-release will include data from North Macedonia, Montenegro and Bosnia Herzegovina. In addition and due to their specific samples, individual datasets for Greece and the Swedish minority in Finland will be published in the context of EVS 2017 (30 + 5 countries). Finally, it will contain all new variables planned for the full release.
The new dataset structure (Main data file and Add-on Matrix data file) will already be applied. That is, we provide the ‘average user’ with a ready-to-use main mixed mode/matrix design data file (full cases only), where no selection of cases nor merging datasets is necessary, and with adequate sample sizes in each country. And provide the ‘expert user’ with an additional matrix design data file containing information and cases on the matrix ‘experiment’ (no follow-up, follow-up refusal, break-off cases), that could be useful for methodological research.
The Full release, in early October, will additionally include data from Portugal and (depending on the impact of coronavirus on fieldwork and on data quality) Luxembourg, Ukraine, and Latvia. Furthermore, there will be individual datasets for Turkey, Romanian-Hungary, and Malta.
It will include the following comprehensively documented datasets:
- Main data file
- Add-on: Matrix data file
- Add-on: Additional country-specific variables
- Add-on: Sensitive data
Full release: 35 countries in 3rd pre-release + 7 new countries (probably not all possible until early Oct)
IDS Full release: 37 integrated and 5 individual datasets (probably not all possible until early Oct)
