title: World Values Survey Wave 7 (2017-2022) Cross-National Data-Set
title: WVS7v6.0.0

description: The World Values Survey (WVS) is an international research program devoted to the scientific and academic study of social, political, economic, religious and cultural values of people in the world. The project’s goal is to assess which impact values stability or change over time has on the social, political and economic development of countries and societies. The project grew out of the European Values Study and was started in 1981 by its Founder and first President (1981-2013) Professor Ronald Inglehart from the University of Michigan (USA) and his team, and since then has been operating in more than 120 world societies. The main research instrument of the project is a representative comparative social survey which is conducted globally every 5 years. Extensive geographical and thematic scope, free availability of survey data and project findings for broad public turned the WVS into one of the most authoritative and widely-used cross-national surveys in the social sciences. At the moment, WVS is the largest non-commercial cross-national empirical time-series investigation of human beliefs and values ever executed.
description: Interview
description: Mode of collection: mixed mode; Face-to-face interview: CAPI (Computer Assisted Personal Interview); Face-to-face interview: PAPI (Paper and Pencil Interview); Telephone interview: CATI (Computer Assisted Telephone Interview); Self-administered questionnaire: CAWI (Computer-Assisted Web Interview); Self-administered questionnaire: Paper; Web-based interview. In all countries, fieldwork was conducted on the basis of detailed and uniform instructions prepared by the WVS scientific advisory committee and WVSA secretariat. The main data collection mode in WVS 2017-2022 is face to face (interviewer-administered) with a printed (PAPI) or electronic (CAPI) questionnaire. Several countries employed self-administered interview or mixed-mode approach to data collection: Australia (CAWI; postal survey); Canada (CAWI); Great Britain (CAPI; CAWI; postal survey; web-based interview (Video interviewing); Hong Kong SAR (PAPI; CAWI); Malaysia (CAWI; PAPI); Netherlands (CAWI); Northern Ireland (CAPI; CAWI; postal survey; web-based interview (Video interviewing); USA (CAWI; CATI). The WVS Master Questionnaire was provided in English, Arabic, Russian and Spanish. Each national survey team had to ensure that the questionnaire was translated into all the languages spoken by 15% or more of the population in the country. WVSA Secretariat and Data archive monitored the translation process; every translation is subject to multi-stage validation procedure before the fieldwork can be started.
description: The target population is defined as: individuals aged 18 (16/17 is acceptable in the countries with such voting age) or older (with no upper age limit), regardless of their nationality, citizenship or language, that have been residing in the [country/ territory] within private households for the past 6 months prior to the date of beginning of fieldwork (or in the date of the first visit to the household, in case of random-route selection).

description: The sampling procedures differ from country to country; probability sample: Multistage Sample, Probability Sample, Simple Random Sample
Nation-wide representative single stage or multi-stage sampling of the adult population of the country 18 (16) years old and older was used for the WVS 2017-2022. Sample size was set as effective sample size: 1200 for countries with population over 2 million, 1000 for countries with population less than 2 million. Countries with great population size and diversity (e.g. China, USA, Russia, Brazil etc.) are requirred to reach an effective sample of N=1500 or larger. Only 3 countries (Argentina, Chile, Uruguay) deviated from the guidelines and planned with an effective sample size below the set threshold. Sample design and other relevant information about sampling were reviewed by the WVS Scientific Advisory Committee and approved prior to contracting of fieldwork agency or starting of data collection. The sampling was documented using the Survey Design Form delivered by the national teams which included the description of the sampling frame and each sampling stage as well as the calculation of the planned gross and net sample size to achieve the required effective sample. Additionally, it included the analytical description of the inclusion probabilities of the sampling design that are used to calculate design weights.
