Financial Literacy Survey 2010 - Bulgaria

Abstract
---------------------------

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.

A total of 1432 respondents from a general population (18+) were interviewed in their homes. Additional booster sample of 186 youth aged 16-17 was implemented.

Sampling procedure
---------------------------

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.

Mode of data collection

Face-to-face [f2f]

Research instrument
---------------------------

- 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.

Response rate
---------------------------

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

摘要
---------------------------
本金融素养调查是世界银行在ECCU5国家金融治理/金融服务消费者保护项目的一部分。该项目旨在提高这些国家的消费者保护水平和金融素养，从而增强金融领域消费者信心。为此，世界银行委托Alpha Research进行一项基线国家代表性调查。研究的目标是评估家庭和消费者的金融素养及信心水平，并在实施提高全民特别是低收入群体金融素养的行动计划之前，概述不同目标群体的特殊性。

共对1432名18岁以上的普通人群进行了家庭访谈。此外，实施了186名16至17岁青年的补充样本。

样本调查数据 [ssd]
抽样程序
---------------------------
样本量和样本框的定义

样本量：基于统计计算，以获得最大标准偏差±2.5%。
- 主要样本：1500名普通人群受访者
- 补充样本：300名16至17岁的受访者

样本框：随机、两阶段分层概率样本，按地理位置大小成比例。
样本包括城市和农村地区，基于以下两个分层标准：
- NUTS区域（6个区域 - 东北、北中、北东、西南、南中、南东）
- 位置类型（5组 - 首都；人口超过10万的区域中心，人口少于10万的区域中心，小城镇，村庄）
抽样程序的执行

- 保加利亚的所有NUTS区域按人口规模降序排列。
- 在第一阶段，样本按每个30个（6个NUTS X 5个位置类型组）的分层标准成比例分配。
- 准备了一个按地区划分的累积列，其中包含每个地区的位置数量。此累积列用于在样本的第二阶段定义样本点的数量，以及相应地 - 每个位置中的受访者数量（按其大小成比例）。
- 样本步长按以下公式计算：样本步长 = 该地区的人口数（N）除以样本中的受访者数。
- 定义了一个随机起始数。
- 每个样本巢中设置了10名受访者，以最大限度地减少样本巢内相关误差的影响。最大的位置包括更多的样本巢。
- 样本巢的数量和每个位置中的受访者数量已按其大小成比例定义。
- 在第二阶段，通过基于“家庭中最后生日”的随机选择，在每个样本点内选择了受访者。
- 样本代表成年人口（18岁以上）。
- 根据相同的标准准备了额外的青年（16-17岁）样本。
