World Values Survey
The World Values Survey (WVS) is a global research project that explores people’s values and beliefs, how they change over time and what social and political impact they have. It is carried out by a worldwide network of social scientists who, since 1981, have conducted representative national surveys in almost 100 countries.The WVS measures, monitors and analyzes: support for democracy, tolerance of foreigners and ethnic minorities, support for gender equality, the role of religion and changing levels of religiosity, the impact of globalization, attitudes toward the environment, work, family, politics, national identity, culture, diversity, insecurity, and subjective well-being.The findings are valuable for policy makers seeking to build civil society and democratic institutions in developing countries. The work is also frequently used by governments around the world, scholars, students, journalists and international organizations and institutions such as the World Bank and the United Nations (UNDP and UN-Habitat). Data from the World Values Survey have for example been used to better understand the motivations behind events such as the Arab Spring, the 2005 French civil unrest, the Rwandan genocide in 1994 and the Yugoslav wars and political upheaval in the 1990s.Romano Prodi, former Prime Minister of Italy and the tenth President of European Commission said about the WVS work: “The growing globalization of the world makes it increasingly important to understand [...] diversity. People with varying beliefs and values can live together and work together productively, but for this to happen it is crucial to understand and appreciate their distinctive worldviews”.
