Joint EVS/WVS 2017-2021 dataset

The European Value Study (EVS) and the World Value Survey (WVS) are two large-scale, cross-national and longitudinal survey research programs. They include a large number of questions, which have been replicated since the early eighties.

In line with the Memorandum of Understandings, both organizations agreed to cooperate in joint data collection from 2017. EVS has been responsible for planning and conducting surveys in European countries, using the EVS questionnaire and EVS methodological guidelines. WVSA has been responsible for planning and conducting surveys in countries in the world outside Europe, using the WVS questionnaire and WVS methodological guidelines. Four countries (Germany, Romania, Russia, and Serbia) conducted surveys in both waves EVS 2017 and WVS7.

Both organisations developed their draft questionnaires independently. The joint items define the Common Core of both questionnaires. They are marked in yellow in the two Master Questionnaires (EVS2017 MQ and WVS7 MQ).

The EVS archive (GESIS-DAS) has been responsible for data archiving and data processing of the European surveys. The WVS archive (JDS Madrid) has been responsible for data archiving and data processing for the non-European surveys including the WVS surveys conducted in Germany, Romania, Russia, and Serbia. Based on the Common EVS/EVS Dictionary agreed by EVS and WVS the Joint EVS/WVS 2017-2021 dataset (Joint EVS/WVS) has been constructed in close collaboration.

The first version of the Joint EVS/WVS includes data and documentation of altogether 79 countries and territories: 34 from the EVS 2017, 49 from the WVS7. Four of these countries conducted surveys in both waves EVS and WVS.
