The World Values Survey is a worldwide investigation of sociocultural and political change. It is conducted by a network of social scientist at leading universities all around world.
Interviews have been carried out with nationally representative samples of the publics of more than 80 societies on all six inhabited continents. The first wave of the values survey was collected in 198. This was mainly a European endeavor (se EVS). From the second wave the global representation rose dramatically making it possible to carry out reliable global cross-cultural analyses and analysis of changes over time. The World Values Survey has produced evidence of gradual but pervasive changes in what people want out of life. Moreover, the survey shows that the basic direction of these changes is, to some extent, predictable.

WVS surveys are required to cover all residents (not only citizens) between the ages of 18 and 85, inclusive. PI's can lower the minimum age limit as long as the minimum required sample size for the 18+ population is achieved.

The preferred method of sampling for WVS surveys is the full probability sample. However, recognizing that the very high cost -in terms of finances, manpower and time- of full probability samples may prove to be prohibitive in some cases, WVS allows quota sampling provided that the following principles are strictly adhered to:
1. Selection of PSUs must be probabilistic (and preferably PPS).
2. Selection of first stage clusters within PSUs must be probabilistic (and preferably PPS).
3. Quota sampling should be used only within reasonably small sized clusters that have been selected probabilistically.
Whether the sampling method is full probability or a combination of probability and quota, the minimum number of PSUs is 30. A design with less than 30 PSUs is not permissible.
B. SAMPLE SIZE
The minimum sample size (i.e. the number of completed interviews) is 1,000. However, given the fact that in most designs the "effective sample size" (sample size net of design effects) is lower than the actual sample size, larger sample sizes are strongly recommended if at all possible.
Non-response is an issue of increasing concern in sample surveys. Investigators are expected to make every reasonable effort to minimize non-response.
1. In countries using a full probability design, no replacements are allowed. PIs should plan on as many call-backs as the funding will allow.
2. In countries using some form of quota sampling, every effort should be made to interview the first contact. In any case, and as indicated below, a full report on non-responses is required.
Dates of Data Collection
Data Collection Mode
In accordance with data protection regulations in participating countries, only anonymous data are available to users. Before depositing data to EVS and WVS, each national team has been responsible for checking their data with confidentiality in mind. Anonymity is also maintained after merging of data files.
The data are available without restrictions, provided that
1. They are used for non-profit purposes
2. Data files are not redistributed
3. Correct citations are provided wherever results based on the data are published. A bibliographic citation or electronic copies of each completed report, article, conference paper or thesis abstract based in part or entirely on these data files is provided to EVS as well as WVS. This citation will be made freely available.
Limitation of Liability
Under no circumstances and under no legal theory, tort, contract, or otherwise, shall the producers of these data files be liable to you or any other person for any indirect, special, incidental, or consequential damages of any character including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any an all other commercial damages or losses. In no event will the producers of these data files be liable for any damages, even if the producers of these data files shall have been informed of the possibility of such damages, or for any claim by any other party. This limitation of liability shall not apply to liability for death of personal injury to the extent applicable law prohibits such limitation. Furthermore, some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this limitation and exclusion may not apply to you.
