World Values Survey 2009, Wave 5

We use probability sample that had been selected in multiple stages with proportional stratification. In the first stage, localities are chosen. In the second stage, the respondents were chosen from the localities with simple random sampling. In the first stage, locality strata have been created and the localities were chosen from these strata with the help of random sampling. All the regions (7) are involved into the sample. For each region 1 additional town and 2-3 villages are selected. In addition, the capital, Budapest is always included into the selected localities, because 20% of Hungarian population live there. About 70 localities are selected. Then, the number of respondents in the previously chosen localities has been defined in accordance with the proportion of the population of the given strata - regions, and different types of localities (towns and villages) within the regions.
Thus, it is assured that each adult with an address in Hungary had equal probability to become a sample member. Random walking The random walking method is a quite widely used sampling method. The underlying idea of this method is that fieldworkers do not receive names and addresses, but a starting point and a route in all sample localities and a standardised procedure to select the individuals to be asked in the selected household. Choosing the localities and the streets When using the random walking method, the sample of localities is created as a first step, with the same method as it was detailed in the previous chapter. After creating the locality sample, the streets are defined with the help of a random technique using a database containing all the street names in the selected localities. The selected streets serve as starting points for the interviewers. Our interviewers receive pre-numbered questionnaires. All visited addresses are recorded on a list. This list contains the identification number of the completed questionnaires, the adapted Leslie Kish key of the sample member, his/her name, his/her address, and codes representing the success or the reason of the fallout. Choosing the house As the street is defined for the interviewers, he/she can freely choose the first house between the street numbers 1 and 4. On the side of the chosen house, the interviewer must select every fourth house/house gate as a sample house. At the end of the street, the interviewer has to proceed on the other side of the street. If one of the houses falls out, for some reason (e.g. it is inhabitable, one-flat house and the household member refuses to participate in the research), it has to be documented on the list (code of fall-out) and carry on the interviews in the next fourth house. Choosing the flat If there is more than one flat in the house, and the house has only a ground floor, than the second flat should be picked. and the house has one floor, then the second flat on the first floor should be chosen. and the house has an odd number of floors, than the second flat of the middle floor should be chosen (e.g. the house has five floors than the second flat of the third floor should be chosen). - and the house has an even number of floors, than the floor number should be halved and second flat on that floor should be included into the sample (e.g. the house has four floors than the second flat on the second floor should be chosen). The second flat is the one that is the second from the gate or the house entrance. All chosen addresses have to be administered on the list. Choosing the person answering the questionnaire The interviewer has to contact the family living in the chosen flat/house. Contact is considered successful if the interviewer could talk to one of the adults living in that flat. The person to be interviewed is chosen with the help of the key belonging to that flat. This above-mentioned key running from one to six belongs to a pre-defined table (adapted Leslie Kish keys). The rows and columns of the tables make up a matrix which makes it possible that all adult persons living in the same flat have an equal chance to become a sample member, independently from the household size. (The tables are found on the back of the covers of each questionnaire.) This page contains six numbered tables. The key number and the table number has to be matched and based on the information provided by an adult family member, the person to be interviewed is to be picked. This person is defined by the cell of the table where the rows contain the number of persons above 18 years old in the family, and the columns contain the number of males living the same family. The person to be interviewed has to be older than 18.
The sample size for Hungary is N=1007.
