EVS (European Values Study) and WVS (World Values Survey)
European Values Systems Study Group (EVSSG) carried out the first EVS surveys in several Western European countries in 1981. The World Values Surveys series was started when the original EVS study evoked such interest that it was replicated in 14 additional countries. EVS and WVS surveys have been carried out in several waves.
Structurally, the international surveys of the World Values Survey (WVS) series resemble the Eurobarometers and the ISSP surveys. Citizen activities, attitudes, and basic values in different countries are studied with integrated, structured surveys.
European Values Study group is responsible for the EVS data collection. The planning of the WVS has been carried out by the World Values Survey network. FSD collections cover Finnish data from 1996 onwards.
