The SBS survey of non-financial enterprises covers sections B to N (excluding K) and division S95, according to NACE.BG-2008, which are divided into four annexes - Industry (B, C, D and E), Construction (F), Distributive Trades (G) and Services (H, I, J, L, M, N and S95). For the period 2002 - 2007 the data were compiled by NACE.BG-2003 and were observed only sections C to I and section K. Since 2008 the data are compiled by NACE.BG-2008.
The annual data of non-financial enterprises are aggregated by sections (the first sign of NACE.BG-2008 and NACE.BG-2003).
The annual data, grouping by size class: the indicators are published on section level (the first sign of NACE.BG-2008 and NACE.BG-2003) and by size class of employment.
Annual regional data: Three indicators are published on a regional level by sections (the first sign of NACE.BG-2008 and NACE.BG-2003) and by statistical regions (NUTS).
The type and the content of the indicators and the aggregate levels are fully compliant with the European regulations on SBS, detailed in 'Legal acts and rules'.
Non-financial enterprises, classified in sections B to N (excluding K) and division S95 by NACE.BG-2008 from 2008 onwards, sections C to I and section K by NACE.BG-2003 for the period 2002 - 2007.
|Statistical concepts and definitions|
The main SBS indicators are:
The basic unit of SBS survey is an enterprise. The overall SBS indicators and the data by size class of employment are calculated from the annual data of the enterprises.
The enterprise is the smallest organisation unit producing goods or services which makes its own business decisions. The enterprise carries out one or more activities at one or more locations. The enterprise may be an independent legal unit.
Another statistical unit of SBS survey is a local unit which is the separate part of the enterprise (workshop, factory, warehouse, office, store, etc.). It is located throughout the country, carries out one or more activities and has at least one employee (even part-time). The data from local units are completed by the enterprise in the form 'Information for local units', as an integral part of its annual report and is used for calculation the regional SBS data.
The SBS survey is exhaustive and the statistical population includes all non-financial enterprises classified in sections B to N (excluding K) and division S95 by NACE.BG-2008 from 2008 onwards, sections C to I and section K by NACE.BG-2003 for the period 2002 - 2007.
The data refer to the activities of non-financial enterprises carried out in the country.
Since 2008 (the data are calculated by NACE.BG-2008);
2002-2007 (the data are calculated by NACE.BG-2003).
|Unit of measure|
|Legal acts and other agreements|
European SBS Regulations:
The SBS data are provided to Eurostat in accordance with the SBS Regulations. The same data are used to fill other international questionnaires (UNIDO) and data exchange under signed agreements, ensuring the protection of confidential information.
|Confidentiality - policy|
Regulation (EC) № 223/2009 of 11 March 2009 defines common criteria for protection of confidential data and methods for sending the information to and its use by Eurostat. The Law on Statistics ensures the protection of statistical confidentiality and the use of individual data of enterprises for statistical purposes only.
|Confidentiality - data treatment|
The individual (primary) data are confidential according to the Law on Statistics and European legislation. To ensure their protection and inability to be identified, the aggregated indicators are also defined as confidential when:
The data are published in accordance with the deadline specified in the Release Calendar presenting the results of the statistical surveys carried out by the National Statistical Institute.
|Release calendar access|
The calendar is available on the NSI website: https://www.nsi.bg/en/node/480
Data are published on the NSI website and are available to all users of statistical information.
|Frequency of dissemination|
|Accessibility and clarity|
Regular press release for the preliminary SBS data.
The SBS data are available to all users of the NSI website under the heading Business statistics - Annual Business Statistics - Structural Business Statistics - Non-financial Enterprises:
Information service on request, according to the Rules for dissemination of statistical products and services of NSI.
|Documentation on methodology|
Eurostat's methodological manual concerning SBS data, based on the European legislation on SBS and the harmonised national legislation in the same field: https://www.nsi.bg/sites/default/files/files/metadata/SBS_Methodology_KID2008_NF_2_EN.pdf
National quality reports according to the SBS Regulations: https://www.nsi.bg/en/node/8057
This includes the improvement of the on-line based information system 'Business statistics', which ensures strict arithmetical and logical input control. The additional output control is made when are registered the big differences in the value of given indicator between two consecutive years or in comparison with the results of other statistical surveys in NSI - Short-term statistics, statistics Prodcom, Foreign trade, Labor force.
This is made in accordance with the standard criteria for assessing the quality - relevance, accuracy and reliability, timeliness, comparability and coherence.
The main users of SBS data are:
There has been no study of user satisfaction, but no cases of outstanding requests for information are registered.
For the period 2002-2008 the requirements of European regulations are met with a few exceptions, but since 2009 the compliance has been 100%.
|Accuracy and reliability|
The statistical data have good accuracy and reliability.
The SBS survey is exhaustive and there are no sampling errors.
|Timeliness and punctuality|
The deadlines for the publication of SBS data on national level are t+8 months for the preliminary data and t+11 months for the final data. In the Eurostat the preliminary and the final SBS data will be sent after t+10 months and t+18 months respectively, where t is the reference year.
The deadlines for publication are strictly followed.
|Coherence and comparability|
|Comparability - geographical|
The methodology for calculating the SBS indicators is fully harmonized with the European legislation on SBS, which ensures comparability of data between Bulgaria and the other EU Member States, which have also fulfilled these requirements.
|Comparability - over time|
The comparability of the data is limited by the use of different classifications of economic activities (NACE.BG-2008 and NACE.BG-2003), if there is a difference in the scope of the activity. The data series are fully comparable for the period 2008 - the last reference year, and the period 2002-2007.
|Coherence - cross domain|
A study, conducted by Eurostat for the differences between logically related data from various surveys, have shown that the data differ in the range of 1%, which is quite normal and is due to different methodology or source.
|Coherence - internal|
Between interrelated SBS data series (a common module and data grouping by size-class of employment) there are no differences, but between the data of common module and the regional data the differences are methodological - the calculation of the first is based on the enterprise, while the second is based on the local unit.
|Cost and burden|
NSI of Bulgaria is making extraordinary efforts to reduce the respondents' burden. An example is the signed agreement called 'Single Entry Point' between NSI and the National Revenue Agency for a single providing of the annual reports and using the data from both institutions. Developed by NSI on-line based information system 'Business Statistics' and ensured methodological and technical assistance to respondents during the reporting campaign are highly appreciated by respondents and help to reduce their workload.
|Data revision - policy|
The National policy, as well as Eurostat's, allows the revision of already published data if there are serious reasons. Any revisions made in the national data are reflected in the aggregated data for the European Union.
|Data revision - practice|
The revised data replace the already published data as soon as possible after the revision is made.
The main data sources for calculating the SBS data are:
|Frequency of data collection|
Exhaustively for all non-financial enterprises covered in the SBS survey.
Data validation is made by additional logical input control and comparison between the output data and the results of the previous year and other surveys, carried out by NSI.
The survey is exhaustive and further data evaluation is not made. The SBS indicators are calculated on the enterprise (local unit) level and are aggregated in accordance with the requirements of the SBS regulations.
