Methodology, Data, Documentation
EVS covers a period spanning from 1981 to 2017 with a core questionnaire repeated over time surveyed on representative samples of the resident adult population in each country. Over time, the EVS methodology has been strengthened to bring the data quality to a high level. Each national survey conforms to guidelines designed to ensure quality and consistency.
EVS data and documentation are available free of charge. They are stored at GESIS – Leibniz Institute for the Social Sciences in Cologne, Germany.
