The World Values Survey (WVS) is one of the world's largest and longest time-series global social research programs. WVS studies changing values and their impact on social and political life. The WVS has carried out representative national surveys in over 100 countries and societies containing almost 90 percent of the world’s population. These surveys show pervasive changes in what people want out of life and what they believe. In order to monitor these changes, the WVS has conducted six survey rounds, from 1981 to nowadays. Work on analyzing this data has been invaluable for a global network of scholars and international development agencies, including the World Bank, the UNDP, the WHO, regional development banks and other agencies
WVS wave 7 constitutes the next round of the World Values Survey program. Around 100 000 respondents in over 70 world countries will be interviewed in the course of 2017-2019 on a great scope of issues, including social values, attitudes & stereotypes; societal well-being; social capital, trust and organizational membership; economic values; corruption; migration; post-materialist index; science & technology; religious values; security; ethical values & norms; political interest and political participation; political culture and political regimes.
The WVS-7 survey was launched in January 2017 with Bolivia becoming the first country to conduct WVS-7. In the course of 2017 and 2018, WVS-7 will be conducted in the USA, Canada, Mexico, Brazil, Argentina, Chile, Uruguay, Andorra, Thailand, Spain, Greece, Serbia, Romania, Russia, Germany, Sweden, Australia, New Zealand, Japan and several dozens of other world countries. WVS-7 will deliver also a number of new countries where the survey has never been conducted yet, including Bolivia, the United Arab Emirates, Greece, Mongolia and a number of countries in Sub-Saharan Africa.
At the WAPOR-2018 conference we would like to introduce the WVS-7 survey round to the community of survey researchers and present overview of methodological approaches and survey techniques used by the WVS-7 teams around the globe.
