EVS Trend File 1981-2017 (pre-release)
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.

Beware: The pre-release is intended to make a first data set version quickly available for research. It is based on the updated data of the EVS Longitudinal Data File 1981-2008 (v.3.1.0) and the data of the current EVS 2017 Integrated Dataset (v.4.0.0). However, the data of the pre-release cannot yet be easily merged with the current WVS Trend File and only basic documentation is available.
The next data release is planned in cooperation between the European Value Study and the World Value Survey (WVS) for the beginning of July 2021. From these data files, it will be easy for data users to build the Integrated Values Surveys 1981-2021 data file, which will then include the five waves of the EVS (1981-2017) and the seven waves of the WVS (1981-2021).
The new concept of the EVS and WVS trend files
Both organisations have agreed on a new concept to transfer the large EVS and WVS longitudinal data files, which contain almost all variables of the EVS and WVS waves respectively, into leaner and easier to handle files. The two new EVS and WVS trend files are based on the Common EVS/WVS Dictionary (v.2021). It includes the large number of questions, which have been replicated by EVS and/or WVS since the early eighties. At the variable level, two inclusion requirements were agreed upon to identify trend variables within the EVS or WVS and across both projects.
- According to requirement 1, all variables that have been used at least twice in the EVS or twice in the WVS are included in the respective EVS or WVS trend file.
- According to requirement 2, all variables that have been used at least once in EVS and once in WVS are included in the respective EVS or WVS trend file.
As a result, the EVS Trend File is based on the updated data of the five EVS waves and contains the variables that correspond to the two requirements mentioned.
