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.
Finland has participated in WVS from the very beginning with materials collected by Gallup Finland (Kantar TNS). WVS/EVS data are usually collected with face-to-face interviews. However, in 1990 and in 2009 (the fourth wave of EVS), the Finnish material was collected via GallupChannel.
