ANNEX

Quality reports and criteria for the evaluation of the quality of structural business statistics

SECTION I

Quality reports

Supplementary guidance on interpretation of the common quality criteria is set out in the Structural Business Statistics Manual produced by the Commission (Eurostat) in cooperation with the Member States. The quality report shall contain both quantitative and qualitative information. The Commission (Eurostat) shall provide the results for those quantitative indicators which can be calculated from data provided by Member States. Member States shall comment on the indicators and assist Eurostat with interpreting them, in the light of their collection methodology, and shall provide the remaining quantitative indicators and qualitative information.

Member States shall provide:

—	a report covering the quality aspects of Annexes I to IV to Regulation (EC) No 295/2008. If deemed necessary, Member States may provide separate reports on Annexes I, II, III and IV to that Regulation,

—	a report covering the quality aspects of Annex V to Regulation (EC) No 295/2008,

—	a report covering the quality aspects of Annex VI to Regulation (EC) No 295/2008,

—	a report covering the quality aspects of Annex VII to Regulation (EC) No 295/2008,

—

a report covering the quality aspects of Annex VIII to Regulation (EC) No 295/2008. If the information needed to compile the statistics of Annex VIII to that Regulation is collected by the same survey as of its Annexes I to IV, a separate report on the quality aspects of its Annex VIII need not be provided,

—	a report covering the quality aspects of Annex IX to Regulation (EC) No 295/2008.

SECTION II

Timeline

Every year starting from 2011, the Commission (Eurostat) shall supply the Member States, by the end of January, with quality reports on reference year t-3, partly pre-filled with quantitative indicators and other information available to the Commission (Eurostat).

Every year Member States shall supply the Commission (Eurostat), by 31 March, with the completed quality reports.

SECTION III

Quality criteria

Data transmitted by Member States on the statistics of Annexes I to IX to Regulation (EC) No 295/2008 shall be evaluated against the quality criteria listed in Article 12(1) of Regulation (EC) No 223/2009 of the European Parliament and of the Council (1), i.e. relevance, accuracy, timeliness, punctuality, accessibility, clarity, comparability and coherence.

1.   Relevance

Relevance means the degree to which statistics meet current and potential needs of the users.

2.   Accuracy

Accuracy means the closeness of estimates to the unknown true values.

3.   Coherence

Coherence means the adequacy of the data to be reliably combined in different ways and for various uses.

4.   Comparability

Comparability means measurement of the impact of differences in applied statistical concepts, measurement tools and procedures, where statistics are compared between geographical areas, sectoral domains or over time.

5.   Timeliness and punctuality

Timeliness means the period between the availability of the information and the event or phenomenon it describes. Punctuality means the delay between the date of release of the data and the target date (the date by which the data should have been delivered).

6.   Accessibility and clarity

Accessibility and clarity means the conditions and modalities by which users can obtain, use and interpret data.

SECTION IV

Series of quantitative indicators to be provided by Member States regarding accuracy (and reliability)

The quantitative indicators described in this section need to be provided only for the statistics listed in Annexes I to IV to Regulation (EC) No 295/2008, as specified below. The data shall be transmitted using the technical format described in Section V of the Annex to this Regulation.

1.   Coefficients of variation

The following information needs to be provided only if sample surveys or a combination of sample surveys and administrative data are used:

Member States shall report information on the characteristics, levels and series specified below. Aspects to be taken into account for calculation of the coefficients of variation shall be further defined in cooperation with Member States. A description of the method used for calculation of the coefficients of variation (including software) shall be included in the quality report.

(a)

For the annual enterprise statistics on the activities covered by NACE Rev. 2, Sections B to J and L to N, and division 95 (data provided under series 1A, 2A, 3A and 4A, as defined in Commission Regulation (EC) No 251/2009 (2)), the coefficient of variation of the following characteristics (as defined in Commission Regulation (EC) No 250/2009 (3)) shall be provided in the level of detail of the activity breakdown specified below: — Characteristic 12110 at NACE Rev. 2 three-digit level (groups), — Characteristics 11110, 12110, 12150, 13310, 15110 and 16110 at NACE Rev. 2 section level for Sections B to J and L to N and NACE Rev. 2 two-digit level (divisions) for divisions 45 to 47 and 95.

(b)

For the annual enterprise statistics broken down by size classes of employment on the activities covered by NACE Rev. 2, Sections C to J and L to N, and division 95 (data provided under series 1B, 2B, 3B and 4B), the coefficient of variation shall be provided in the level of detail of the activity breakdown and for the size classes of employment specified below: — Characteristics 11110, 12110, 12150 and 16110, — NACE Rev. 2 section level for Sections B to J and L to N and NACE Rev. 2 two-digit level (divisions) for division 95, — Size classes 0-9, 10-19, 20-49, 50-249 and 250 + for NACE Rev. 2, Sections B to F, and 0-1, 2-9, 10-19, 20-49, 50-249 and 250 + for NACE Rev. 2, Sections G to J and L to N, and division 95.

2.   Unit non-response

The following information shall be provided if sample surveys, a combination of sample surveys and administrative data or administrative data only are used. Aspects to be taken into account for calculation of unit non-response shall be further defined in cooperation with Member States.

Member States shall report the weighted unit non-response information on the activities covered by NACE Rev. 2, Sections B to J and L to N, and division 95 at NACE Rev. 2 three-digit level. If several surveys/administrative sources are used for characteristics 11110, 12110, 12150, 13310, 15110 and 16110, separate unit non-response indicators shall be transmitted, mentioning the variable number in the field concerned. Unit non-response shall be weighted, preferably by number of persons employed. Alternatively, turnover may be used.

SECTION V

Technical format for transmission of the quality report and quality indicators

For transmission of the report and the series of quality indicators, the appropriate dataset identifiers shall be used. The detailed content of the quality reports shall be agreed in cooperation with the Member States. Member States shall complete the pre-filled quality reports and return them to the Commission (Eurostat). For reporting the two quality indicators (coefficients of variation and unit non-response), the record structure defined below shall be used, which is similar to the technical format for transmission of structural business statistics.

1.   Dataset identifiers

The following dataset identifiers shall be used for reporting on quality criteria for structural business statistics:
