The Financial Literacy survey is part of a World Bank Financial Governance/Consumer Protection in Financial Services Program in ECCU5 Countries. The Program aims to improve the levels of consumer protection and financial literacy in these countries—and thereby strengthen consumer confidence in the financial sectors. To this end the World Bank commissioned to the Alpha Research a baseline national representative survey. The objective of the study is to assess the level of financial literacy and consumer confidence of households and to outline the peculiarities in different target groups prior to the implementation of the action plan for increasing the financial literacy of the general population and in particular of the lowincome groups.

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:
- Main sample: total number of 1500 respondents were reached and 1432 were conducted:
* Response rate – 95%
* Refusal rate - 5%
* Main reason for refusals: the length of interview
- Booster sample of young citizens aged 16 – 17 y.o.: total number of 300 respondents were reached and 186 interviews were conducted:
* Response rate – 62%
* Refusal rate – 38%
* Main reason for refusals: the subject of the survey

Data collection supervision
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.
- The questionnaire is based on the model Financial Literacy Survey questionnaire used in Romania in order to achieve comparison of the results between the countries.
- Questions from previous surveys on financial literacy issues conducted in Bulgaria have been included in the questionnaire as well. This allows comparison of the survey results with those of previous studies.
- The questionnaire was reviewed with the relevant institutions – Bulgarian National Bank, Ministry of Economy, Energy and Tourism, World Bank.
