Other Household Survey [hh/oth]
World Values Survey Wave 4 1999-2004 covers 41 countries and societies around the world and more than 60,000 respondents. The series includes the following waves:
Wave 6 (2010-2014)
Wave 5 (2005-2009)
Wave 4 (1999-2004)
Wave 3 (1995-1998)
Wave 2 (1990-1994)
Wave 1 (1981-1984)
The World Values Survey (www.worldvaluessurvey.org) is a global network of social scientists studying changing values and their impact on social and political life, led by an international team of scholars, with the WVS association and secretariat headquartered in Stockholm, Sweden.
The survey, which started in 1981, seeks to use the most rigorous, high-quality research designs in each country. The WVS consists of nationally representative surveys conducted in almost 100 countries which contain almost 90 percent of the world’s population, using a common questionnaire. The WVS is the largest non-commercial, cross-national, time series investigation of human beliefs and values ever executed, currently including interviews with almost 400,000 respondents. Moreover the WVS is the only academic study covering the full range of global variations, from very poor to very rich countries, in all of the world’s major cultural zones.
The WVS seeks to help scientists and policy makers understand changes in the beliefs, values and motivations of people throughout the world. Thousands of political scientists, sociologists, social psychologists, anthropologists and economists have used these data to analyze such topics as economic development, democratization, religion, gender equality, social capital, and subjective well-being. These data have also been widely used by government officials, journalists and students, and groups at the World Bank have analyzed the linkages between cultural factors and economic development.

Sampling
Sample size: 1000
The different stages in the sampling procedure were:
- Selecting Provinces in each region
- Selecting districts in each selected province
- Selecting spots in each selected district
The sampled unit we got was the household and the selection method to identify a respondent was the random walk. There were not quota-controls and the stratification factor that we used was sample selected depending on Population at all stages. The household was chosen to be the primary sampling unit. Vietnam was divided into 8 following regions: Red River Delta, North East, North West, South Central Coast, Central Highlands, South East, Mekong Delta. The questionnaires were allocated based on the proportion in population. Define sample provinces were based on probability sampling. It was chosen 5 sample households in each village using a random walk procedure. The identification of the respondents was done after already selecting the household, list all 18 years old and above family members using a selection table key.
Remarks about sampling:
- Final numbers of clusters or sapling points: No clusters
- Sample unit from office sampling: Random walk
There were some limitations when we realised the sample such as a rate of 83% responses against 17% not responses. We received 1000 completed questionnaires out of 1300 asked questionnaires.
No weighting variable was added
Survey instrument
There was a pre-survey preparation: the English questionnaire was translated into Vietnamese. Survey leaders repeatedly reviewed and edited the translated version before finalised Vietnamese version. The questionnaire was pre-tested. Each member of the team tried to answer all the questions in the questionnaire. If any difficult appeared, the team did make change. There have not been any optional WVS questions and/or items been included, however country-specific questions were included at the end of the questionnaire, just before demographics:
- 139a People are talking about continue the reform. You are for or against reform.
- 215a You are considered yourselves as (1) Northern Vietnamese; (2) Southern Vietnamese; (3) Vietnamese only
Some core questions from the WVS were not included such as: V220; V221; V222. The reason was because there is a single party system in this country. The sample was designed to be representative of the entire adult population, i.e. 18 years and older, of your country. The lower age cut-off for the sample was 18 and there was not any upper age cut-off for the sample.

The field quality control was done with 1 field coordinator for each region who observes at least 20% of the total output of the field interviewer. Field coordinators do spot checking or back-checking. Field interviewers do field editing. The training course was held at Vietnam Institute of Human Studies from Sep/30th /01 to August/3rd/01. The content was to learn basic information about the project; learn rules of selecting household, identifying respondent, substitution rules, interviewing techniques and do mock interviews with colleagues. Interviewers were paid according to performance. Calls were made at different times of the day and the minimum number of re-calls required was 3. Approximately 50% of the interviews were supervised. Approximately 20% of the interviews were back-checked.
