WVS wave 7


The 7th wave of the World Values Survey is taking place in 2017-2021. Subsequent waves are planned every five years.

Strategic goals for the 7th wave include:

  • Expansion of territorial coverage from 60 countries in WVS-6 to 80 in WVS-7;
  • Deepening collaboration within the international development community;
  • Deepening collaboration within NGOs, academic institutions & research foundations;
  • Updating the WVS-7 questionnaire with new topics & items covering new social phenomena and emerging processes of value change;
  • Expanding the 7th wave WVS with data useful for monitoring the SDGs;
  • Expanding capacity and resources for survey fieldwork in developing countries.

The 7th wave will continue monitoring cultural values, attitudes and beliefs towards gender, family, and religion; attitudes and experience of poverty; education, health, and security; social tolerance and trust; attitudes towards multilateral institutions; cultural differences and similarities between regions and societies. In addition, the WVS-7 questionnaire has been elaborated with the inclusion of such new topics as the issues of justice, moral principles, corruption, accountability and risk, migration, national security and global governance.

The WVS-7 questionnaire has been finalized in November 2016; in addition to the master version in English, WVSA Secretariat has produced centralized translations into Spanish, Arabic and Russian.

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 has been conducted in the USA, Mexico, Brazil, Argentina, Chile, Ecuador, Peru, Andorra, Greece, Serbia, Romania, Turkey, Russia, Germany, Thailand, Australia, Malaysia, Indonesia, China, Pakistan, Egypt, Jordan, Nigeria, Iraq and over dozen of other world countries. Geographic coverage has also been expanded to several new countries included for the first time, such as Bolivia, Greece, Myanmar, Nicaragua, and Tajikistan.

A new collection of rules and procedures for WVS-7 has been elaborated by the Scientific Advisory Committee of the WVSA and comprises requirements towards sampling procedures, sample size, time of survey implementation, questionnaire localization, data submission to the WVSA Secretariat:

  • WVS requires implementation of the common questionnaire fully and faithfully, in all countries included into one wave. No more than 12 items can be omitted in a country.
  • In any given country, the questionnaire must be translated into all languages which serve as the first language for 15 % (or more) of the population.
  • WVS-7 presumes application of modern translation techniques involving 2 translators and a mediator.
  • Samples must be representative of all people in the age 18 and older residing within private households in each country, regardless of their nationality, citizenship or language. The minimum sample size - i.e. the number of completed interviews which are included into the national data-set in most of countries is 1200. Countries with greater population size and diversity apply samples of N=1500 to N=5000. Countries with the population below 2 million people apply samples of N=1000.
  • The main method of data collection in the WVS survey is face-to-face interview at respondent’s home / place of residence. Other interview modes employed in WVS-7 include postal survey, self-administered online survey, and telephone interview (in combination with other surveying techniques). 

The WVS-7 survey round marks another occasion of a fruitful cooperation and successful partnership between the World Values Survey Association and the European Values Study

Data collection for the WVS-7 survey round will be completed in July 2021. Data and all related survey documentation will be made available at the WVS web-site in free access in two public data releases: in July 2020 and in July 2021. Public launch of the WVS-7 data-set will take place together with the second and final WVS-7 data release and in conjunction with the IPSA-2021 Congress of Political Science in Lisbon, Portugal
