3.1. Data description

Structural business statistics (SBS) describes the structure, conduct and performance of economic activities, down to the most detailed activity level (several hundred economic sectors).

SBS covers all activities of the non-financial business economy with the exception of agricultural activities and personal services. Limited information is available on banking, insurance and pension funds.

Main characteristics (variables) of the SBS data category:

  • Business demographic variables (e.g. Number of enterprises)
  • "Output related" variables (e.g. Turnover, Value added)
  • "Input related" variables: labour input (e.g. Employment, Hours worked); goods and services input (e.g. Total of purchases); capital input (e.g. Material investments)
3.2. Classification system

Statistical Classification of Economic Activities in the European Community (NACE): NACE Rev.1 was used until 2001, NACE Rev. 1.1 since 2002, and NACE Rev 2 is used from 2008 onwards. Key data were double reported in NACE Rev.1.1 and NACE Rev.2 for 2008. From 2009 onwards, only NACE Rev.2 data are available.

The regional breakdown of the EU Member States is based on the Nomenclature of Territorial Units for Statistics (NUTS). Detailed information about the consecutive NUTS Regulations can be found at Eurostat's website.

The product breakdown is based on the Classification of Products by Activity (CPA) as stated in the Regulation establishing CPA 2008 and its amending  Commission Regulation (EU) No 1209/2014  (from reference year 2015 onwards).

 

The classifications used in Structural Business Statistics are:

  • For the classification of economic activities for the year 2008 onwards the classification of the European Union (EU) NACE Rev.2.
  • For the classification of territorial units for statistical purposes, the NUTS 2013 classification.

 

Annex I-IV:

The results of the survey are broken down according to the following classifications:

  1. 4-digit level of economic activity of NACE Rev.2 (lower level of analysis).
  2. 2-digit level of regional breakdown (NUTS 2, NUTS1, NUTS0) at 2-digit level of Nace rev.2. 
3.3. Coverage - sector

The SBS coverage was limited to Sections C to K of NACE Rev.1.1 until 2007. Starting from the reference year 2008 data is available for Sections B to N and Division S95 of NACE Rev.2. With 2013 as the first reference year information is published on NACE codes K6411, K6419 and K65 and its breakdown.

3.4. Statistical concepts and definitions

The statistical characteristics are defined in Annex I of Commission Regulation (EC) No 250/2009

3.5. Statistical unit

Enterprise and local unit, according to Regulation (EEC) 696/93 of the Council.

3.6. Statistical population

6. Institutional Mandate Top
6.1. Institutional Mandate - legal acts and other agreements

Year 1995 was the first year for the implementation of the Council Regulation No 58/97 (SBS Regulation).

The Council Regulation No 58/97 has been amended three times: by Council Regulation No 410/98Commission Regulation No 1614/2002 and European Parliament and Council Regulation No 2056/2002. As a new amendment of the basic Regulation it was decided to recast the Regulation No 58/97 in order to obtain a new "clean" legal text. The European Parliament and Council Regulation No 295/2008 was adopted on 14/02/2008 and the provisions of this Regulation are applicable from the reference year 2008. Regulation No 295/2008 has been amended by Commission Regulation (EU) No 446/2014.

7. Confidentiality Top
7.1. Confidentiality - policy

The issues concerning the observance of statistical confidentiality by the Hellenic Statistical Authority (ELSTAT) are arranged by articles 7, 8 and 9 of the Law 3832/2010 as in force, by Articles 8, 10 and 11(2) of the Regulation on Statistical Obligations of the agencies of the Hellenic Statistical System and by Articles 10 and 15 of the Regulation on the Operation and Administration of ELSTAT, which is avaliable at the following link: http://www.statistics.gr/en/statistical-confidentiality

 

The Statistical Confidentiality Policy of ELSTAT includes the rules and principles implemented by ELSTAT for the observance of statistical confidentiality and is available at the following link:

http://www.statistics.gr/documents/20181/1609796/ELSTAT_Statistical_Confidentiality_Policy_EN.pdf/c79e5ac8-469c-433d-b4e6-8433319b21d2

7.2. Confidentiality - data treatment

The confidential data transmitted to ELSTAT by the agencies of the Hellenic Statistical System (ELSS) are used exclusively for statistical purposes. Authorization to access these data has exclusively only the staff of ELSTAT employed for that purpose and designated by act of the President of ELSTAT. The receipt, storage and processing of data by ELSTAT is carried out by implementing strict security and personal data protection rules, in accordance with ELSTAT’s Circular on the Information Systems Security Policy and Digital Data Protection.

 

------------------------

For primary suppressions, the threshold rule is applied, with a minimum frequency set to 3. For secondary suppressions, the hypercube method is applied.

The Threshold Rule was used to reduce the number of confidential cells.

The impact of the applied measures to reduce the number of confidential cells is evaluated as very good.

Furthermore:

 

  • ELSTAT protects and does not disseminate data it has obtained or it has access to, which enable the direct or indirect identification of the statistical units that have provided them by the disclosure of individual information directly received for statistical purposes or indirectly supplied from administrative or other sources. ELSTAT takes all appropriate preventive measures so as to render impossible the identification of individual statistical units by technical or other means that might reasonably be used by a third party. Statistical data that could potentially enable the identification of the statistical unit are disseminated by ELSTAT if and only if:

a)     these data have been treated, as it is specifically set out in the Regulation on Statistical Obligations of the agencies of the Hellenic Statistical System (ELSS), in such a way that their dissemination does not prejudice statistical confidentiality or

b)     the statistical unit has given its consent, without any reservations, for the disclosure of data.

  • The confidential data that are transmitted by ELSS agencies to ELSTAT are used exclusively for statistical purposes and the only persons who have the right to have access to these data are the personnel engaged in this task and appointed by an act of the President of ELSTAT.
  • ELSTAT may grant researchers conducting statistical analyses for scientific purposes access to data that enable the indirect identification of the statistical units concerned. The access is granted provided the following conditions are satisfied:

a) an appropriate request together with a detailed research proposal in conformity with current scientific standards have been submitted;

b) the research proposal indicates in sufficient detail the set of data to be accessed, the methods of analyzing them, and the time needed for the research;

c) a contract specifying the conditions for access, the obligations of the researchers, the measures for respecting the confidentiality of statistical data and the sanctions in case of breach of these obligations has been signed by the individual researcher, by his/her institution, or by the organization commissioning the research, as the case may be, and by ELSTAT.

  • Issues referring to the observance of statistical confidentiality are examined by the Statistical Confidentiality Committee (SCC) operating in ELSTAT. The responsibilities of this Committee are to make recommendations to the President of ELSTAT on:

a)     the level of detail at which statistical data can be disseminated, so as the identification, either directly or indirectly, of the surveyed statistical unit is not possible;

b)     the anonymization criteria for the microdata provided to users;

c)     the granting to researchers access to confidential data for scientific purposes.

  • The staff of ELSTAT, under any employment status, as well as the temporary survey workers who are employed for the collection of statistical data in statistical surveys conducted by ELSTAT, who acquire access by any means to confidential data, are bound by the principle of confidentiality and must use these data exclusively for the statistical purposes of ELSTAT. After the termination of their term of office, they are not allowed to use these data for any purpose.
  • Violation of data confidentiality and/or statistical confidentiality by any civil servant or employee of ELSTAT constitutes the disciplinary offence of violation of duty and may be punished with the penalty of final dismissal.
  • ELSTAT, by its decision, may impose a penalty amounting from ten thousand (10,000) up to two hundred thousand (200,000) euros to anyone who violates the confidentiality of data and/or statistical confidentiality. The penalty is always imposed after the hearing of the defense of the person liable for the breach, depending on the gravity and the repercussions of the violation. Any relapse constitutes an aggravating factor for the assessment of the administrative sanction.

Quality report is transmitted to Eurostat, on an annual basis, when the compilation and validation of Structural Business Statistics is completed. Section 11.2 provides a more detailed description of the quality report.

Documentation on quality policy is available in greek and english: https://www.statistics.gr/documents/20181/2571f853-1e37-46da-9387-595bbe2a162b


11. Quality management Top
11.1. Quality assurance

The applied methodology is harmonized with the relevant decisions endorsed in the meetings of the European Working Group on Structural Business Statistics (SBSWG) which take place under the coordination of Eurostat, as well as the recommendations of the Task Forces that are established for reviewing specific important issues related to Structural Business Statistics.

ELSTAT’s policy for quality assurance is described at the following link:

http://www.statistics.gr/en/quality-asurance-framework

11.2. Quality management - assessment

Structural Business Statistics are compiled in accordance with the recommendations that are provided in the relevant European Regulations. The evaluation of the quality of the Structural Business Statistics is performed by ELSTAT and Eurostat on the basis of the quality report compiled for each reference year from ELSTAT and to which information on all the quality indicators are recorded (relevance, accuracy and reliability, timeliness and punctuality, coherence and comparability, accessibility and clarity).

Structural Business Statistics are compiled with the use of tax and other data from administrative sources that cover the basic statistical variables. A survey on large enterprises of each economic activity class is supplementarly conducted, in order to collect data for the remaining statistical variables that cannot be calculated from the data coming from the administrative sources and to be used as the basis for the estimation of these statistical variables for the total population of enterprises.

The use of administrative data for the compilation of Structural Business Statistics has brought a significant improvement in the quality of the produced data in terms of completeness and coverage of enterprises, as well as in terms of timeliness.

The continuous cooperation of ELSTAT with the tax and other administrative authorities providing data to ELSTAT aims at having the biggest possible harmonization of statistical variables with tax and other administrative variables, as well as at adding questions in tax and administrative declaration forms that cover needs on statistical information and it, therefore, will lead to further improving the quality of Structural Business Statistics.

Given that SBS data are compiled with the use of administrative tax data that cover all enterprises, their accuracy and coverage are evaluated as high.


12. Relevance Top
12.1. Relevance - User Needs

Data of Structural Business Statistics are provided to users for the satisfaction of their requests, in accordance with the Statistical Confidentiality Policy and the Dissemination Policy of ELSTAT.

The main national users of Structural Business Statistics data are researchers, economic analysts, doctoral candidates, students and enterprises.

At international level, data of Structural Business Statistics are used by Eurostat, the Organisation for Economic Cooperation and Development, etc.

Structural Business Statistics data are also used in the compilation of the National Accounts of Greece and in particular in the compilation of the Gross Domestic Product, as well as in the compilation of Short Term Statistics during the works for the revision of the base year.

12.2. Relevance - User Satisfaction

The degree of satisfaction of users is assessed by their comments and remarks expressed: a) at the annual Users’ Conferences organized by ELSTAT, b) at the meetings of the Advisory Committee of the Hellenic Statistical System (SYEPELSS), in which participate representatives of bodies using statistics and c) through the User Satisfaction Survey conducted by the competent Statistical Data Dissemination Section of ELSTAT:

http://www.statistics.gr/en/user-satisfaction-survey

12.3. Completeness

Structural Business Statistics cover the total set of variables defined by the relevant Regulations of the European Union.


13. Accuracy Top
13.1. Accuracy - overall

For the compilation of Structural Business Statistics administrative, tax data are used, as well as data that are collected in the framework of a small scaled survey conducted only to large enterprises (in terms of the turnover or employment), which dominate the economy of each activity class. The aim of the survey is to collect data for the total set of variables that are required by the Regulation (EC) No 295/2008 of the European Parliament and of the Council on Structural Business Statistics (recast), given that the administrative, tax data do not cover all the required statistical variables.

The accuracy and reliability of Structural Business Statistics depends largely on the accuracy and completeness of the data that are provided from administrative, tax sources and are used for their compilation. In general, it is difficult to estimate the accuracy of administrative, tax data and it does not exist a quantitative indicator for its evaluation. The administrative, tax data that are used for the compilation of Structural Business Statistics are checked as regards their completeness and their correctness, mainly through their comparison with data from other available sources, as well as with data from the Statistical Business Register. In addition, the administrative, tax data are checked in terms of their relevance with the statistical variables, based on the definitions of these variables. In cases administrative, tax data are missing or they are not correct or their complete correction is not feasible, the imputation method is applied.

For the compilation of the statistical variables that cannot be calculated from the administrative, tax data for the total population of enterprises, the data that are collected through the survey on large enterprises are used and appropriate estimation methods are applied, namely the proportion of a component variable method, predictive models, the simple ratio adjustment method.

On the basis of the above, the accuracy of Structural Business Statistics is evaluated as very satisfactory.

13.2. Sampling error

Sampling errors do not exist.

13.3. Non-sampling error

13.3.1 Coverage errors
Structural Business Statistics cover, in general, all the active enterprises of the Statistical Business Register, which are classified in the activity classes that are referred in section 3.3. Differences between Structural Business Statistics and the Statistical Business Register may exist, which correspond to cases of enterprises of a special form or legal status, which are included in the Statistical Business Register, but they are out of the scope of Structural Business Statistics. Moreover, other differences between Structural Business Statistics and the Statistical Business Register may occur, which usually correspond to enterprises that are in a transitional status (e.g. start of operation, closing of operation) and which are included in the Statistical Business Register but they are not included in Structural Business Statistics because financial data are not available, while their data cannot be estimated through the imputation method.

 

13.3.2 Measurement errors

Structural Business Statistics are compiled with the use of administrative, tax data and data that are collected through the supplementary small scaled survey on the large enterprises of each activity class. The logical and accounting checks that are performed on the above data aim at the correction of false data that may exist in the tax and other administrative fields, as well as false data that are collected through the statistical surveys.

 

13.3.3 Processing errors

The errors that occurred during the processing of the data are identified through logical, accounting and statistical checks and they are corrected.

 

13.3.4 Non-Response errors

In case of non-response (concerns only the survey for the large enterprises) of an enterprise, the following actions were taken:

1. sending an informative letter to the enterprise and

2. contact by phone with the responsible accountant.


14. Timeliness and punctuality Top
14.1. Timeliness

The time-lag between the reference period of Structural Business Statistics data and their availability is 18 months.

14.2. Punctuality

The results of Structural Business Statistics of the most recent reference year 2020 were compiled within the deadline, namely 18 months after the end of the reference year, as provided in the Regulation (EC) No 295/2008 of the European Parliament and of the Council on Structural Business Statistics (recast).


15. Coherence and comparability Top
15.1. Comparability - geographical

Structural Business Statistics are compiled in full compliance with the European Regulation (EC) No 295/2008 of the European Parliament and of the Council on Structural Business Statistics (recast), a fact that ensures the comparability of the data within regions of Greece and with the respective data of the other countries of the EU.

15.2. Comparability - over time

The time series of Structural Business Statistics starts from the reference year 2000.

In the reference year 2008 there is a discontinuity in the comparability over time of the time series due to the revision of the statistical classification of economic activities that is used (transition from the classification Nace Rev 1.1. to the classification Nace Rev. 2). In order to address the discontinuity in the time series due to the use of different statistical classifications, data on Structural Business Statistics for the year 2008 have been compiled with both the statistical classifications Nace Rev. 1.1 and Nace Rev. 2.

In the reference year 2014 there is a discontinuity in the comparability over time of the time series due to the change in the compilation method of Structural Business Statistics with the transition from the sampling survey and the extrapolation of the results to the population of enterprises, to the introduction of the use of administrative, tax data. Due to the fact that ELSTAT was not granted with access to analytical administrative, tax data for the reference year 2013 and the previous years, this discontinuity in the time series of Structural Business Statistics is not possible to be addressed. The Greek SBS data for the reference year 2014 onwards, introduce a break in the timeseries. In the reference year 2018 there is a discontinuity in the comperability over time of the time series, due to the full implementation of the statistical unit "enterprise".

15.3. Coherence - cross domain

Data relevant to those of Structural Business Statistics exist in the Statistical Business Register, in Business Demography Statistics, in Short Term Statistics, in Labour Cost Statistics, in Labour Force Statistics and in the Statistics on the Expenditures for the Protection of the Environment. Given the methodological differences that exist in these domains, inconsistencies in the results may be explained. Obvious inconsistencies between the results of Structural Business Statistics and the results of the above domains, that may occur, are examined.

 

15.3.1 Coherence – sub annual and annual statistics

Structural Business Statistics data are compiled only on an annual basis.

 

15.3.2 Coherence – National Accounts

Structural Business Statistics are used as a source for the compilation of National Accounts and in particular of the Gross Domestic Product (GDP) with all the three calculation methods (from the production side, from the expenditure side and from the income side). Due to methodological differences that exist between Structural Business Statistics and National Accounts, inconsistencies in the final results are expected.

15.4. Coherence - internal

The internal coherence of data regards the relations between statistical variables and the coherence between different data series that are compiled for Structural Business Statistics. The internal coherence of Structural Business Statistics is checked through a dedicated software that has been developed by Eurostat and its application is a necessary condition for the validation of Structural Business Statistics.


16. Cost and Burden Top

The access of ELSTAT to data of administrative sources that are used for the compilation of Structural Business Statistics is free of charge. Also, using data from administrative sources to update Structural Business Statistics does not cause any burden on the surveyed legal units.

The use, by ELSTAT, of automated logical and statistical checks for the processing of the above data results in saving time and resources for the compilation of Structural Business Statistics.

The small scaled survey on the large enterprises of the different economic activity classes is mainly conducted by ELSTAT’s staff. External private collaborators who collect questionnaires work for a small share of the enterprises of the region. For the Structural Business Statistics of the year 2020, the cost of the survey which corresponds to the cost of private collaborators was 14,429.45€.

18. Statistical processing Top
18.1. Source data

The primary data that are used for the compilation of Structural Business Statistics are administrative data, data that are collected through statistical surveys conducted by ELSTAT on large enterprises and data from the Statistical Business Register of ELSTAT.

The administrative data received by ELSTAT and used for the compilation of Structural Business Statistics are transmitted from the Independent Authority of Public Revenues (IAPR) and include: (a) financial data of freelancers, physical and legal persons that are obliged, by the law, to submit tax declarations on their income from economic activity, (b) data on the compensations of employees deriving from the Electronic Earnings Attestations that employers are obliged to submit for the employees they occupy.

Through the survey on the large enterprises that is conducted by ELSTAT, analytical financial data on income and expenditure are collected as regards the economic activity of the enterprises.

Data on the status of enterprises (active, inactive, etc), on the branch of their economic activity, on the residence of the enterprise, employment data (number of persons employed and number of employees) and data on the local units of enterprises are received from the Statistical Business Register.

18.2. Frequency of data collection

Annual data collection

18.3. Data collection

Data are transmitted to ELSTAT from IAPR, according to the Memorandum of Understanding signed in 2014, between ELSTAT, the ex General Secretariat for Public Revenues (GSPR-currently IAPR), the General Secretariat for Information Systems (GSIS) and the ex Social Security Institution (IKA-currently EFKA). The tax data that are transmitted to ELSTAT from the IAPR, as well as their transmission time are specified in the Annexes of the Agreement that was signed in June 2016 between ELSTAT and GSPR.

The data of the surveyed large enterprises are collected through the completion of electronic or printed questionnaires.

18.4. Data validation

Both the data that are received by IAPR and collected through the survey are subject to a set of computational checks, in order their completeness, accuracy and coherence to be verified. In addition, the consistency of the data is checked through the performance of automated accounting-mathematical checks. The derived inconsistencies are further examined and corrections take place at the level of the enterprise data, in cases the observed deviations cannot be justified. An analytical file recording all the corrections that are conducted, according to the above, is kept. 

18.5. Data compilation

Data from administrative sources

When the administrative data are received from IAPR, a comparison of their total number of records is made with all the other relevant administrative data files that ELSTAT is receiving from IAPR for the updating requirements of the Statistical Business Register. A comparison with the corresponding file of the previous year is made as well.

Moreover, the cases of enterprises that are recorded more than once in the file with the administrative data are checked. This is possible to occur when supplementary or modifying tax declarations are submitted by enterprises to IAPR.

After that, accounting-mathematical checks are conducted, concerning the following basic categories:

  • fields that are related to the identity of the enterprise
  • activity branch
  • reference period
  • verification of totals
  • checks on the existence of basic financial data per enterprise
  • correlation of employment and personnel costs data
  • checks on negative values
  • checks on the correctness of the financial result
  • checks on the total income from services

The work of the correction of administrative data with the use of mathematical – accounting checks is divided into manual (at the enterprise level), automated and other corrections.

After the phase of processing and correction of the administrative data (E3 form), the calculation of the statistical variables follows. The calculation of the statistical variables is conducted with the use of a correspondence table between the E3 tax form fields and the statistical variables, which has been compiled by ELSTAT. Exceptions from this process are the statistical variables “number of persons employed” and “number of employees” which are directly received by the Statistical Business Register, as well as the variable “wages and salaries” that is calculated from the administrative datafile Electronic Earnings Attestation.

 

When the calculation of the statistical variables is completed, coherence and comparability checks are conducted and the processing of the data at the level of statistical variables initiates.

 

In particular, the following individual processing – checking tasks are performed:

  • For specific activities (processing and trading of smoke products, alcoholic beverages, petroleum and pharmaceutical products), the values of turnover and of total purchases of goods and services are checked and corrected, when necessary, in order not to include the special consumption tax, rebates and claw backs.
  • Examination, at enterprise level, of negative values in the statistical variables turnover and gross investments in tangible goods.
  • Examination of the consistency between variables “personnel cost” and “wages and salaries”. The personnel cost is calculated from the fields of E3 tax form, while wages and salaries from the fields of the Electronic Earnings Attestation. Therefore, consistency problems may occur for some enterprises, as they come from different sources.
  • Examination of the consistency of the variables “number of employees” and “wages and salaries”. This check mainly concerns the cases of enterprises that did not submit the Electronic Earnings Attestation or they have submitted it with zero data, but, at the same time, information on the existence of employees in these enterprises are available by another source (e.g. ex Social Security Institution (IKA-currently EFKA)).

Moreover, for the administrating companies of the maritime sector, a special treatment takes place, as regards the estimation of the statistical variables for the established offices/branches of non-resident enterprises as provided in article 25 of L. 27/1975. The relative activity codes of Nace Rev. 2 classification are: 5020, 5222, 5229.

These administrating companies are branches of non-resident enterprises and, in their majority, they declare only the personnel cost and the expenses they make for purchasing goods and services (the expenses of the office for the administration of the vessels), without submitting financial data on turnover either through the Structural Business Statistics survey or through the tax forms (E3, F2, etc).

 

Data collected through the survey on large enterprises

The data that are collected on large enterprises are coded and checked in terms of their completeness, validity and correctness in relation to the documents that these enterprises have also submitted (balance sheets, financial statements, tax forms, etc). After that, the data are entered in databases and they are subject to computational checks, logical checks and completeness checks. Then, the calculation of the variables follows.

 

Estimation of statistical variables that cannot be calculated from the administrative data

For the large enterprises, for which data are collected through the survey, the collected data are used.

For the rest of the enterprises of the active enterprises population, which are classified in the activity branches that are covered by the Structural Business Statistics, the following techniques – methods are applied:

-        Proportion of a component variable

-        Predictive models

-        Simple Ratio adjustment method

 

Synthesis of results

After the processing phases described previously have been completed, as well as after the completion of the survey on the large enterprises, the synthesis of Structural Business Statistics is conducted.

The SBS results for 2020 are compiled with the full implementation of the statistical unit enterprise. In particular, the SBS results of 2020 were initially compiled with the implementation of the statistical unit “legal unit”. Then by eliminating from the results the intra-flows data (collected through a dedicated special survey) between the legal units of the same enterprises, the SBS results for 2020 were calculated with the implementation of the statistical unit “enterprise”.

 

18.5.1 Imputation – rate

The final results of Structural Business Statistics include data (at the level of enterprise) that do not come from a primary source (survey on large enterprises of administrative files), but they have been estimated through the application of statistical methods. In particular, the data of enterprises that, (a) either are not available from the E3 tax form, (b) either are available from the E3 tax form, but they are not considered to be correctly completed and at the same time they have a big impact on the activity class in which they are classified, or (c) they have been corrected at the level of the statistical variables, they are replaced by the data of other enterprises that have similar characteristics (activity class, size class as regards the turnover or the employment) and that have submitted the E3 tax form without any accounting-mathematical errors to be detected. This process is conducted on the basis of a specific statistical methodology.

As regards the magnitude of the impact that the imputation process has, it is noted that for the year 2020, the data for which this process was applied concerned 7,087 enterprises with a turnover of 2.8 billion euros and 28,330 persons employed. The respective figures for the results of the year 2019 were: 6,376 enterprises, 3.2 billion euros turnover, and 31,345 persons employed.
