The Law of Statistics enacted on 25 June 1999, subsequently amended in 2001, 2002, 2004
and 2005 provides the legal basis and general framework for “the realisation of statistical
activity by Bulgarian Bodies of Statistics, registers and information systems they maintain as
well as data exchange between them” - article 1. This Law repeals the Law on Statistics of 1991
(as amended in 1991, 1992 and 1997) and its general provisions conform well to the basic
principles and requirements of EU standards - the Council Regulation 322/97. According to the
article 2 (2) of the Law of statistics “The statistical activity is carried out in compliance with the
principles of the rule of law, impartiality, reliability, efficiency, adequacy, publicity and
confidentiality”. The application of the principle of transparency is guaranteed with the
provision of article 22 - “The Bodies of statistics are obliged to announce in appropriate
manner and to notify in writing the persons, who are subject to the statistical surveys, of their
rights and obligations, the purpose, scope and manner of carrying out the surveys, as well as
the guarantees for data confidentiality and protection of secrecy”.

According to the article 3 (1) of the Law of Statistics “The Bodies of statistics are carrying out
the statistical activity of the State by conducting periodical and ad-hoc statistical surveys,
included in the National Programme for Statistical Surveys and/or are funded by them ”. The
Program is elaborated on an annual base and is endorsed by the Council of Ministers upon a
proposal of the President of NSI. The Law of statistics provides the Bodies of statistics with the
legal right to require the mandatory participation of the respondents to all surveys listed into
the National Programme, including SBS survey.
General obligation of enterpriGeneral obligation of enterpriGeneral obligation of enterpriGeneral obligation of enterprises to replyses to replyses to replyses to reply
Article 20 of the Law of Statistics states that all legal persons and natural persons (including
farmers), who are carrying out economic activity are obliged to provide the Bodies of Statistics
with data needed in those statistical surveys for which mandatory participation is required
according to the National Programme for Statistical Surveys.
Obligation to safeguard confidential dataObligation to safeguard confidential dataObligation to safeguard confidential dataObligation to safeguard confidential data
The Law of Statistics includes provisions relating to data confidentiality and protection of
secrecy, which are in compliance with the EU legislation (Council Regulation N 322/97) and
standard European practice. Requirements, obligations and measures for data protection, as
well as fines that can be imposed, are treated in separate chapters - Chapter 6 "Protection of
secrecy" and Chapter 9 "Administrative and liability provisions”. Article 25 of the Law specifys
the criteria, according to which certain data cannot be made public or released – individual
data, data which could be indirectly identified, as well as aggregations of less than three
statistical units and/or when the relative share of one unit is more than 85% of the total volume.
The exceptional cases in which data listed in article 25 can be provided (for ex. under written
agreement of the respondent) are specified in article 26 of the Law of statistics.
Right of access to administrative dataRight of access to administrative dataRight of access to administrative dataRight of access to administrative data
According to article 20 (6) of the Law of Statistics the Bodies of Statistics have the right under
written request to obtain free of charge from other State bodies and register keepers, data
collected by them, which are required in the statistical surveys, included in the National
Programme for Statistical Surveys. The provision of these administrative data (mostly
aggregates) is organised by formal agreements between the NSI and each of the bodies such as
Ministry of Finance, respectively the Insurance Supervision Agency, Bulgarian National Bank and
others. So far NSI does not have access to the individual records of Tax Register, which could be
particularly helpful for improving the coverage and quality of the SBS data and for reducing the
response burden.

As the last amendments of the Statistical Law entered into force since 4 of November 2005, no

In the first instance the team of division “Business registers” in NSI is responsible for classifying
activities. The survey team makes updates and corrections of enterprises’ principle economic
activity, based on the information collected by the surveys.

In theory value added is recommended to be used to identify the principal and secondary
activities. In practice turnover is used for determination of the principal and secondary activities
of the statistical units.
Method used for identifying activitiesMethod used for identifying activitiesMethod used for identifying activitiesMethod used for identifying activities
Top-down approach is applied following the hierarchical principle for identification of the
principal activity, starting from most aggregated level of NACE rev. 1.1 classification (Section)
and than step by step determining the rest more detailed levels.
Stability rules appliedStability rules appliedStability rules appliedStability rules applied
The principal activity of the enterprises is updates once a year on the base of the annual SBS
survey (in particular for industrial enterprises using data on PRODCOM survey as well). In case
that during the reference year given enterprise has performed non-typical activity, in terms of
use of the fixed assets, its principal activity is kept unchanged. This rule is followed two years
even if the turnover from the non-typical activity for the reference year is higher than the
turnover from the recorded principal activity. After two years period if it is proved that the
change of production structure is a permanent tendency the original principal activity of this
enterprise is changed.

Purpose of the registerPurpose of the registerPurpose of the registerPurpose of the register
The main purpose of Register of statistical units EKPOU 96 is to serve as a sampling frame for
the statistical surveys and for the extrapolation of their results. The use of business register for
these purposes is under certain convention due to underreporting about non-active enterprises
and existence of some falsely active units.
Legal basisLegal basisLegal basisLegal basis
The Law of Statistics (article 30) provides the legal basis for establishment and maintaining of
Register of statistical units. The Law on Statistics entered into force on 25 June 1999 and
subsequently was amended in 2001, 2002, 2004 and 2005. This Law repealed the Law on
Statistics of 1991, as amended in 1991, 1992 and 1997.
Obligation to register for births and deathsObligation to register for births and deathsObligation to register for births and deathsObligation to register for births and deaths
The main source of information for birds and deaths of legal units that is used for updating the
Register of statistical units, is the administrative register called “BULSTAT”, which is also
maintained by NSI. According to the legislation all economic entities are obliged to record in
Register “BULSTAT” in order legitimately to carry out economic activity. This guarantees the
availability of all newly registered units into the Register of statistical units. As concerns death
legal units, nevertheless their legal obligations to inform the Register “BULSTAT” (and
consequently the Register of statistical units) about their cessation due to underreporting still
there are some falsely active units.

This variable is collected in the SBS survey. The gross investment in tangible goods include all
expenditure on acquisition of tangible fixed assets with construction activity and purchase –
new and existing tangible capital goods. Purchased goods are valued at purchase price, which
include transport and installation charges, fees and other costs of ownership. Alternation,
improvements and renovations, which prolong the service life or increase the productive
capacity of capital goods, are also included.
Gross investment in tangible goods is based on gross investment in land, in existing buildings
and structures, in construction and alteration of buildings, in machinery and equipment.
Expenditure on acquisition of tangible fixed assets in fruitful permanent crops (till they reach
maturity) as well as productive and draught animals are included in gross investment in
tangible goods. Current maintenance costs are excluded, as is the value and current
expenditure on capital goods used under rental and lease contracts. Investment in intangible
and financial assets arealso excluded.

Primary confidential data are identified by the application of two criteria (national confidentiality
rules), specified in the Law of statistics, according to which statistics cannot be made public or
released when: 1/ Data summarized information for less than three statistical units (Criteria A)
and 2/ The relative dominance of the data of one unit is more than 85% of the total volume of
aggregated data (Criteria B).

Description of the calculation procedure of the coefficients of variationDescription of the calculation procedure of the coefficients of variationDescription of the calculation procedure of the coefficients of variationDescription of the calculation procedure of the coefficients of variation
The coefficients of variation are equal to 0 due to the fact that SBS survey is census and the
three component errors that have to be taken into account in their calculation don’t have any or
have very negligible impact: Sampling error = 0; Misclassification error = 0 because it is
observed and updated through SBS survey itself; non-response rate is very small (5,1 % in terms
of number of enterprises and 0,6 % in terms of turnover) and it doesn’t affect large and medium
sized enterprises, because they are fully responded.

Analysis of produced information is made: First data analysis is done at the enterprise level.
Internal coherency of the indicators within the questionnaire is checked by ratios between
variables. The coherency of results with previous years' results is also checked. Second the
results are checked with data from other surveys performed by NSI (PRODCOM Survey, Short-
term Surveys and International Trade). Information on these measures is not published yet.
