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
Because of the size and complexity of the survey population, multi-stage probability sampling methods are used to develop the sample frame for this study.
Stage 1: The total household population of Iran is divided into 28 strata based on the provincial boundariestwenty-seven provinces plus the province of Tehran. In each province, the household population is divided into urban and rural areas. And each urban and rural area is further divided into Census blocks. The SCI has detailed maps of all these urban and rural areas. These areas are divided into Census Enumeration Areas or blocks, which are the smallest geographically specified units. Each unit includes at least ten dwellings for the urban areas and at least one for the rural areas. A block is defined as an area where one can start enumeration from one point and go around the unit and return to the starting point. The size and the population density of these blocks vary. The number of these blocks and their distributions as urban versus rural areas also vary from province to province. In the 28 provinces, the blocks are sampled with probabilities proportionate to size measured in total dwelling units. In the 28 provinces, blocks are sampled in proportion to the total number of dwelling units. In metropolitan areas, where blocks fall into districts with varying socioeconomic status (high, medium, low), these areas are first stratified into homogeneous districts, and then blocks are sampled.
Stage 2: The second stage units of the surveys multi-stage sample design include individual dwelling units, in which respondents reside. The SCI has provided the list of all the dwelling units within each of the selected blocks. A random sample of dwellings units will be selected for contact from the listing for each block. The result will be about 3000 dwellings of which 1800 will be from urban and 1200 from rural areas. The table below shows the population size according to the 1996 Census and its distribution of the population in the urban and rural areas by provinces, the sampled Census blocks, and the share of the sample of households for the urban and rural areas of each province. A final adjustment of the sample size may be made according to the homogeneity or the heterogeneity of the area being sampled. The level of education and economic development are considered the major criteria for assessing the degree of homogeneity of the population.
Stage 3: A single respondent from each sample dwelling unit will be selected according to procedure specified in charts provided to the interviewers. There were three differences between the 2000 and 2005 samples. First, in 2000 sample, the interviewers were not able to get to the provinces of Sistan va Baluchistan and Kurdistan. But in 2005 these provinces were surveyed. Second, in the 2005 the province of Kurdistan was oversampled to allow comparison with Iraqi Kurds. Third, the number of province ware increased to thirty-one in 2005.
The sample size for Iran is N=2667 and includes the national population aged 16 years and over for both sexes.
Survey instrument
The WVS questionnaire was translated into Persian from the English questionnaire by a member of the research team. The translated questionnaire was also pre-tested. The questionnaire was administered to 200 individuals. In 2005 survey, no question was omitted.

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.
