World Values Survey 2001, Wave 4

Sample size: 1055

Sampling methodology and the sampling procedure was face-to-face interview, paper and pencil, in home of the respondent. Selection of households was executed on random route principle ibid. In urban areas each third household on the left-hand side of the street, applying left turn at junctions and going back to the last crossing if one has reached a dead-end, further proceeding at random but not along the branching one had been through. In a block-of-flats, if it is a building with maximum four floors, the selected household is each fifth flat on the left, substitute being, in cases of refusal, the next fifth flat, or in cases of unsuitable household (for ex. Macedonian family when needed Albanian one) the next - door flat. In a block-of-flats of 5 floors and more, the selection is every tenth flat on the left with the same procedure for substitution - in cases of refusal the next tenth flat on the left and in cases of unsuitable household the next door flat. In rural area, each fourth inhabitable house/dwelling on both sides of the route/track and where they are aligned or scattered over larger territory, wave-wise approach selecting the fourth, counting from the left. In compounds of several houses behind a common fence, the instruction rules to select the fourth from the left (counting from the gate), or if there are less than four houses behind a common fence than the interviewer to go out of the common yard counting the houses as if they were on the street. In compact and well-structured villages with negligible signs of destruction the selection procedure follows the instructions for urban areas. Selection of a respondent was carried out via "next birthday" selection key. The achieved sampling plan comprised of 161 sampling points 124 Macedonian and 37 Albanian, 4-8 respondents per unit in urban area and 4-8 respondents per unit in rural area, proportional to regional profile of different portions of the surveyed universe.
