The EVS Trend File 1981-2017 is constructed from the five EVS waves and covers almost 40 years. In altogether 159 surveys, more than 223.000 respondents from 48 countries/regions were interviewed.
It is based on the updated data of the EVS Longitudinal Data File 1981-2008 (v.3.1.0) and the current EVS 2017 Integrated Dataset (v.4.0.0). The Trend File follows a new concept agreed between EVS and WVS to transfer their large longitudinal data files into leaner and easier to handle files based on the Common EVS/WVS Dictionary (v.2021). The next release is planned in cooperation with the World Value Survey (WVS) for the beginning of July 2021. From these new Trend files, it will be easy for data users to build the Integrated Values Surveys 1981-2021. For more information, please go to the EVS Trend File 1981-2017.
The data and documentation are accessible through the GESIS data collection at GESIS- Leibniz Institute for the Social Sciences.
