World Values Survey Wave 5 2009-2005 covers 58 countries and societies around the world and more than 83,000 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
Sampling is the process of selecting certain members of a group in such a way that they will represent the universe. Selection of respondents for the project followed a stratified Multi-Stage
Random Selection Procedure as follows:
Selection of Sectors/EAs: Sectors are defined as sampling blocks of equal geographical dimensions with identifiable boundaries, encompassing a substantial number of people. Sectors were divided into high, medium and low density areas. Each of the sectors was thereafter randomly selected from each area using the available street maps already sectorised into different density areas. Where maps are not available, especially for rural areas, an exhaustive list of all sectors was considered. The sample allocated to each density area i.e. high/medium and low was proportionate to the number of sectors in each group. The overall sample for the urban and rural locations determined the number of sectors selected. However, a maximum of five (05) interviews were conducted in each randomly selected sector. All sectors were selected by simple random method via a random numbered table. Group interviewing techniques were adopted for the study across all the study locations. By this design, a team of interviewers under the leadership of a supervisor moved as a group to each selected sector, and then completed the assigned quota for that sector before moving to another sector. This afforded the supervisors the opportunity to closely monitor the interviewers under them. The questionnaire was precoded using the alphabet letters A to K excluding letter I.
Selection of Sampling/Entering Points within each sector: Immediately after the selection of the sectors, the supervisors surveyed each of the selected sectors to determine the sampling/entering points of the sector. These are points where the team started their days interviewing. These can be prominent structures such as churches, mosques, schools, hospitals, etc.
Selection of Dwelling Structure within each sector: In each of the randomly selected sectors, the Days Code was used to determine each interviewers starting point, i.e. [The first house/dwelling structure to enter/approach]. A dwelling structure is defined as a floor of a distinct residential building within a sector of a town/village; where only one household occupied a multi-storey building, the entire building [and not the floor] constituted a dwelling structure. Where it is a multi-storey building with multiple occupants, counting of floors was carried out consistently from the upper floor to the ground floor in an unbroken chain from floor to floor. A fixed sampling gap of one in three (1:3) and one in five (1:5) respectively was observed after each successful call in low, medium and high density areas.
Selection of Household: On entering a selected dwelling structure, each interviewer determined the number of households within the structure. Having done that, the interviewer then used the household selection grid to determine the household where the interview would take place. A household is defined as the collective individuals living under the same roof and having a common feeding arrangement and also with a recognised person in the household as the head of household. Only residents who have stayed in the selected household for at least six [6] months were interviewed. Visiting relations who have stayed for less than six months were not regarded as household members.
Substitution of Households: In the case where the selected room was unoccupied, interviewers were instructed to replace with the next household. Only one substitution was allowed per dwelling structure.
Selection of Respondents: Respondents were randomly selected among the male and female household members. In order to select the final person to interview within the selected household, all the male and female residents of Mali, aged 16 years and above in the selected household were listed by names and ages on the respondents selection grid on the questionnaires. The listing was done from the eldest to the youngest (males and females combined) and then one respondent was selected using the Kish grid a table of randomly generated numbers.
Call Backs/Substitution Criteria: In the case where the selected adult in the household was not available at the time of the call, interviewers were instructed to make up to two additional recalls on different times of the day including evenings when the selected respondent was said to be at home.
However, where the selected adult was not available for interviewing within the days of selection, interviewers were asked to regard such a case as a non-response situation or ineffective call. No substitution of respondents within the same household/dwelling structure was allowed.
Coverage/Achievement: The training was organised in five central locations to cover the regions as follows:
- The central briefing in Bamako centre to cover: Bamako and the region of Koulikoro (15 interviewers, 3 supervisors and 2 quality controllers)
- Sikasso center to cover the region of Sikasso (16 interviewers, 3 supervisors and 1 quality controller)
- Kayes center to cover the region of Kayes (11 interviewers, 2 supervisors and 1 quality controller)
- Segou center to cover the region of Segou (16 interviewers, 3 supervisors and 1 quality controller)
- Mopti center to cover the region of Mopti (14 interviewers, 3 supervisors and 1 quality controller)
At the end of fieldwork, the total number ofeffective calls achieved was one thousand five hundred and thirty eight [1,538].
Remarks about sampling:
Substitution of Households: In the case where the selected room was unoccupied, interviewers were instructed to replace with the next household. Only one substitution was allowed per dwelling structure.
Call Backs/Substitution Criteria: In the case where the selected adult in the household was not available at the time of the call, interviewers were instructed to make up to two additional recalls on different times of the day including evenings when the selected respondent was said to be at home. However, where the selected adult was not available for interviewing within the days of selection, interviewers were asked to regard such a case as a non-response situation or ineffective call. No substitution of respondents within the same household/dwelling structure was allowed.
The sample size for Mali is N=1534 and includes national population aged 16 years and over for both sexes.
Survey instrument
20 pilot interviews were conducted among respondents from various demographics to check that questions were understandable and amend the wording of some questions when necessary In order to facilitate the quality of field operations, the questionnaire was translated into French, the official language in Mali. During the briefing session, the questionnaire was loosely translated into Bambara (the major language spoken in Mali) for the purpose of common understanding and to facilitate communication should the interviewers encounter illiterate respondents. The following are problems encountered by or comments made by interviewers and supervisors working on this study:
- The length of the questionnaire: almost all the respondents complained that the interview was too long. Some respondents even had to stop the interview half way.
- There were cases of selected female respondents who refused to answer the questions of the interviewers in absence of their husbands.
- The environmental concepts (such as in V111 - Global warming or the greenhouse effect-, V112 - Global warming or the greenhouse effect, V113 - Pollution of rivers, lakes and oceans) were difficult to explain to illiterate respondents.
- Subjects like (V.38 & V.41) homosexuality and unmarried couples living together seemed to be embarrassing for some respondents who didnt want to talk about them or mostly answered without much conviction.
- Question V 238: It was difficult for the respondents to give spontaneously the total duration of their education, especially for older respondents.
- Questions V242: Respondents working in the informal sectors considering themselves as professionals.
- Question V253: Respondents usually felt uncomfortable talking about their income. Its something confidential which is not easy to disclose.

The main method of data collection in the WVS survey is face-to-face interview at respondent’s home / place of residence. Respondent’s answers could be recorded in a paper questionnaire (traditional way) or by CAPI (Computer Assisted Personal Interview). The approval of the Scientific Advisory Committee in writing is necessary for application of any methods of data collection other than face-to-face interview. Following the sampling, each country is left with a representative national sample of its public. These persons are then interviewed during a limited time frame decided by the Executive Committee of the World Values Survey using the uniformly structured questionnaires. The survey is carried out by professional organizations using face-to-face interviews or phone interviews for remote areas. Each country has a Principal Investigator (social scientists working in academic institutions) who is responsible for conducting the survey in accordance with the fixed rules and procedures. During the field work, the agency has to report in writing according to a specific check-list. Internal consistency checks are made between the sampling design and the outcome and rigorous data cleaning procedures are followed at the WVS data archive. No country is included in a wave before full documentation has been delivered. This means a data set with the completed methodological questionnaire and a report of country-specific information (for example important political events during the fieldwork, problems particular to the country). Once all the surveys are completed, the Principal Investigator has access to all surveys and data. Non-response is an issue of increasing concern in sample surveys. Investigators are expected to make every reasonable effort to minimize non-response. In countries using a full probability design, no replacements are allowed. PIs should plan on as many call-backs as the funding will allow. In countries using some form of quota sampling, every effort should be made to interview the first contact.
