Sampling
Definition of sample size and sample frame
Sample size: based on statistical calculations in order to obtain max. standard deviation +/- 2.5% .
- Main sample - 1500 respondents general population
- Booster – 300 respondents 16-17 years old
Sample frame: random, two-staged stratified sample with probability, proportional to the size of the location. The sample include both urban and rural areas and is based on two stratification criteria:
- NUTS region (6 regions – North-West, North-Central, North-East, South-West, South-Central, South-East)
- Type of location (5 groups – Capital; Regional center with more than 100000 citizens, Regional center with less than 100000 citizens, Small town, Village)
Implementation of the sampling procedure
- All NUTS regions in Bulgaria have been ranged in descending order according to the size of the population.
- At the first stage the sample was distributed proportionally on the size of population in each of the 30 (6 NUTS X 5 type of location groups) strata different from zero.
- A cumulative column with the number of locations in each region was prepared. This cumulative column is used for defining the number of the sample points at the second stage of the sample and respectively – the number of the respondents in each location (proportionally to its’ size).
- The sample step was calculated according to the following formula: Sample step = Number of population in the region (N) divided on the number of respondents in the sample.
- A random starting number was defined.
- A number of 10 respondents in each sample nest have been set in order to minimize the influence of correlation error within the sample nest. The largest locations include a higher number of sample nests.
- The number of sample nests and the number of respondents in each location have been defined, proportionally to their size.
- At a second-stage, using the random selection based on the “last birthday in the household”, the respondents were selected within each sample point.
- The sample is representative for the adult population (18+).
- Additional sample booster of young people (16-17 years old) was prepared according to the same criteria.
A total number of 1800 respondents were reached and 1618 interviews were conducted:

The supervisors’ team did quality control on the interviewers’ work from the head office in Sofia. 20% (325 respondents) of the total sample were back checked by phone:
- 295 respondents were contacted personally and confirmed that they were interviewed.
- 30 respondents were not available at the time of control, but another member of the household confirmed that the interview was conducted.
Consistence and logic check on all completed questionnaires was carried out by the central office staff.
No weighting procedures were applied.
Development of training materials, delivery of trainings for supervisors and interviewers. Conducting a pilot survey.
- The team was been given a special briefing session before the beginning of the study. They were acquainted with the survey objectives and tasks, the instruction for conducting the interview and the peculiarities of the questionnaire’s structure.
- 15 pilot interviews were conducted in order to test how the questionnaire would work in a local environment. Average length of the interview: 60 minutes. The shortest interview was 40 minutes and the longest - 90 minutes.
- The general observations from the pilot test were:
- The questionnaire was twice longer than the 30 minutes length pointed out in the TOR.
- There were long options that required repeat of question. The suggestion was to use a show card with the possible answers that could be shown to the respondents.
Fieldwork/Interviewing process
- The fieldwork was conducted by the team of 75 interviewers from Alpha Research. The average number of interviews per interviewer was 21.
- The fieldwork manager in the head office in Sofia was in permanent contact with the regional supervisors. There were no significant difficulties during the survey fieldwork.
