Sample design

Type of the sample applied in the Study

Sample based on three-level sampling procedure;

2-nd - residence addresses,

3-rd - (in case of more than single-person household) selection of the respondent from multi-member household.

Geographic coverage of the sample

Lower age cut-off for the sample18
Upper age cut-off for the samplebrak

Data collection methods were used for the study

"face-to-face" interview

The total number of starting or issued names/addresses and the total number of successfully completed

starting or issued names/addresses3240
sucessfully completed1794

Substitution or replacement of respondents

Post-stratification weight


Factors considered at construction of the post-stratified weighting factor

sex, age, educational level, place of residence, economic activity

Weighting or post-stratification strategy used

The weight consists of the following parameters:

1) sex (2 categories: male and female), age (5 different categories for males and females: males: 18-24, 25-34, 35-49, 50-64 and 65 or more; females: 18-24, 25-34, 35-49, 50-59 and 60 or more), educational level (4 categories: elementary, basic vocational, secondary and higher), place of residence (4 categories: villages, cities 20000 or less, cities 20000-100000, and cities more then 100000 inhabitatnts) and economic activity.

2) Because of the probability of selection inside the household are inversely proportional to the number of adults in the household another procedure was implemented to correct such an uneqall probabilities by weighting the results by the number of adults in the household.
