When forming the sample a two stage cluster’s sampling on a territorial principle is implemented as follows: at the first stage the clusters are selected (enumeration areas from the last Census); at the second stage the households to be surveyed are identified. Up to 2009 the selection of territorial units is done with a probability proportional to their size. Since 2010 non-proportional selection has applied in order to produce more accurate sample data in the small regions where the minimum quarter size of the sample include no less 72 households at the expense of decrease of the number of households in the large regions - Sofia (stolitsa), Plovdiv and Varna. In the selected enumeration areas (clusters) lists of the household are prepared and they are arranged into ascending order, depending on the number of persons. This indicator has a close correlation with the surveyed indicators - income, expenditure, and consumption per capita. 6 households from these lists are chosen from each cluster with a selection step. Since 2010 the sample size has been 3 060 households divided in three sub-samples each containing 1 020 households. Each sub-sample is surveyed one month per quarter by application of the method of rotation sample. Each household participates in the survey four months during the 12-month period. The household budget survey applies the principle of the voluntary participation of households which had randomly come into the sample. Every randomly selected household which is not willing or is not able to cooperate is replaced with another from the same cluster and with the same number of members. Main documents of the Household budget survey are: Household dairy; Three questionnaires.

Since 2010 the households have kept retrospective records on: · irregular expenditure on non-foods during the previous two months; · some irregular income during the previous two months. By interview data are collected on: · social demographic characteristics of the household and its members · availability of facilities and durables at the dwelling · availability of food products at the beginning of the month of observation and residues at the end of the month · the presence of farm animals in the household.

Non-sampling error

Like any statistical survey and household budget survey may contain non-sampling errors that arise at different stages of the study and which cannot be completely eliminated.

Such errors are basically:

· coverage errors

· measurement errors that occur at the time of data collection

· processing errors

· non-response errors

In order to reduce non-sampling errors:

· update of the household lists for each of the first stage selection census enumeration areas;

· development of a clear research methodology, ongoing updating of data coding systems;

· using interviewers with experience in collecting, controlling, encoding and inputting data;

· conducting regular training seminars for the interviewers;

· assistance to the interviewers of the survey team at NSI;

· data control at the collection, input, and processing stage.

Coverage error

Some of the sampled households cannot be found at the address. In order to preserve the sample size, the principle of substitution applies to these households.

Replaced households not contacted in 2023

Reasons for replacement	2023
Reasons for replacement	Number of replacements	% from the sample
Not contacted	1176	38.4
Not found or do not live at the address	77	2.5
Absent or impossible access	1099	35.9

Over-coverage - rate

Not applicable.

Common units - proportion

Not applicable.

Measurement error

At the data collection stage, errors may also occur:

· inaccurate or incomplete answers from respondents - to minimize these errors, interviewers check the correctness and completeness of the records by asking additional reminders;

· improperly recorded data from the interviewers - a large number of arithmetic and logic controls have been introduced in the processing programs to limit this type of error.

Non response error

Some of the households in the sample do not want or cannot participate in the survey for a variety of reasons:

· skepticism in respect of the survey objectives

· skepticism in respect of the official institutions

· suspicion in preserving anonymity

· insufficient remuneration for participation

· lack of time

· other reasons for refusal

· poor health

· lack of communication with the household because of misunderstanding and non-communication in Bulgarian

· other reasons

To reduce the negative impact on estimates of non-response, the household budget survey uses the substitution principle.Every randomly selected household which is not willing or is not able to cooperate is replaced with another from the same cluster and with the same number of members.

Item non-response - rate

Not applicable.

Processing error

In order to minimize possible errors, a large number of arithmetic and logical controls are included in the programs for input and processing of household budget survey data. For example:

- For the items of the monetary expenses for which they are registered quantities and values, upon data entry automatically is calculated price and it is checked whether the price is within minimum and maximum price limits.

- Ownership of the dwelling is tied to the payment or not of rent for a dwelling, and the availability of central heating - respectively the paid bills for heating.

- A logical link is established between the registered economic activity of the person and the corresponding type of income received by him as salary, pension, compensation etc.

- Completed or ongoing education is tied to the age of the person.

- The presence of farm animals of a given species is associated with the products derived therefrom such as milk, eggs, meat, honey, wool.

All arithmetic and logical controls are detailed in the study's terms of reference.
