World Values Survey

It is an ongoing academic project by social scientists to assess the state of sociocultural, moral, religious and political values of different cultures around the world. Its results are largely available on the project's internet website.

History
The World Values Survey first emerged out of the European Values Study (EVS) in 1981, when the methods of a successful European study were extended to 14 countries outside Europe. The 1981 study nevertheless covered only 22 countries worldwide. The EVS was conducted under the aegis of Jan Kerkhofs and Ruud de Moor and continues to be based in the Netherlands at the Tilburg University. The leading figure in the early extension of the surveys around the world was Ronald Inglehart from the University of Michigan in the United States.

The survey was repeated after an interval of about 10 years in the second of what came to be termed "waves". One of the aims of the project came to be the longitudinal (as well as cross-cultural) measurement of variation of values. Further waves followed the second wave at intervals of approximately 5 years.

Due to the European origin of the project, the early waves of the WVS were eurocentric in emphasis, with especially weak representation in Africa and South-East Asia. To expand, the WVS adopted a strongly decentralised structure. Suitable academic representatives from new countries were free to join in a quasi-democratic network. Joining meant that new representatives had to conduct the predefined survey in their own country with at least 1000 interviewees. They could then exchange their data with the WVS in return for the data from the rest of the project. Funding was primarily local, with representatives in each country funding their own part of the project. In this way the WVS grew out of its eurocentric origins to embrace 42 countries in the 2nd wave, 54 in the 3rd wave and 62 in the 4th wave.

Today the database of the WVS has been published on the internet with free access. The Secretariat of the WVS is based in Sweden.

The official archive of the World Values Survey is located in [ASEP/JDS] (Madrid), Spain.

Methodology and scope
The WVS methodology consists of the administration of detailed questionnaires in face-to-face interviews. The questionnaires from all five waves (including the incomplete 2005/2006 wave) can be viewed in full on the WVS website. The questionnaires from the most recent waves have consisted of about 250 questions. In each country the questionnaires are administered to about 1000 to 3500 interviewees, with an average in the 4th wave of about 1330 interviews per country and a worldwide total of about 92000 interviews. It has to be kept in mind that the sampling methods used in the country survey are not identical. As a result the Slovenian social scientist Adam hints to conserable differences between the results of the European Value Study 2001, which aggregates the European country studies of the World Values Survey, and the European Social Survey 2002/2003.

Results
The WVS questionnaire consists of about 250 questions resulting in some 400 to 800 measurable variables. A few examples are as follows:


 * Happiness. Perceptions of happiness were measured and this part of the WVS is that most widely quoted by the press. The popular statistics website Nationmaster publishes a simplified world happiness scale derived from the WVS data. The WVS website allows a more sophisticated level of analysis than Nationmaster, such as comparison of happiness over time or across socio-economic groups. One of the most striking shifts in happiness measured by the WVS was the substantial drop in happiness of Russians and some other Eastern European countries during the 1990s.


 * The Inglehart Map is another of the most well-known results of the WVS survey. A number of variables were condensed into two dimensions of cultural variation (known as "traditional v. secular-rational" and "survival v. self-expression"), and on this basis the world's countries could be mapped into specific cultural regions. The WVS claims: "These two dimensions explain more than 70 percent of the cross-national variance in a factor analysis of ten indicators".


 * The survey found that trust and democracy were values that crossed most cultural boundaries. The survey also showed that sex equality was one of the most significant differences between Western and other cultures.

Literature derived from the WVS
The Dutch intercultural researcher Geert Hofstede positively receives research based on the WVS results. Referring specifically to Inglehart's two-dimensional reduction of his results as represented by the Inglehart Map, Hofstede claims that it supports his own work. "Inglehart's key cultural dimensions were significantly correlated with [my] dimensions. Well-being versus survival correlated strongly with individualism and masculinity; secular-rational versus traditional authority correlated negatively with power distance." However, Inglehart's two dimensions are not identical to Hofstede's five dimensions. Given the differences in methodology (Hofstede's research came from work values surveys given to IBM employees) it is unsurprising that there are differences between his results and those of the World Values Survey.
