Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

Commission Implementing Regulation 2020/1197 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics repealing 10 legal acts in the field of business statistic (General Implementing Act)
National context :
Statec is the National Institute of statistics and economic studies of the Grand Duchy of Luxembourg. Statec's administration is placed under the authority of the Ministry of the Economy and Foreign Trade. It is professionally and scientifically independent, i.e. it sets its own work programme in accordance with national and European statistical legislation, produces and disseminates data in complete neutrality.
The Law of July 10, 2011 on the organisation of the National Institute for Statistics and Economic Studies sets out the missions of Statec and its internal organisation. These missions are to provide a public information service of high quality to public and private decision-makers as well as to citizens. Statec is committed to produce statistics, analyses and studies giving a detailed, reliable and objective image of the society of Luxembourg.
Statec coordinates the statistical system of Luxembourg, organised according to the principle of statistical centralisation. For this purpose it widely relies on collaboration with other producers of data as well as with public and private research centres. Statec so centralises data available from public authorities to carry out its studies, but also to make them available to its users on a single platform. With the new law of July 10, 2011, applied scientific research is added to Statec’s missions.
6.2. Institutional Mandate - data sharing
There is no general datasharing. Nevertheless, results are sent to Eurostat.
7.1. Confidentiality - policy
STATEC guarantees the non-disclosure of confidential information when the statistical results are disseminated.
See Article 16 of the « Loi du 10 juillet 2011 portant organisation de l’Institut national de la statistique et des etudes économiques » (law of 10 July 2011 on the organization of the National Institute for Statistics and Economic Studies).
7.2. Confidentiality - data treatment
The ESS confidentiality rules are applied.
8.1. Release calendar
The industrial producer price index is generally published the last day of the month (data M-1).
The release days are the days data are transmitted to Eurostat. According to the principle of independence, data is released to all users at the same time.
There is a monthly transmission to Eurostat according to the delays of transmission foreseen in the EBS-Regulation.
10.1. Dissemination format - News release
There is no news release.
10.2. Dissemination format - Publications
Monthly publication "Indicateur à court terme A3" / "Short-term indicator A3" available on internet and in paper format.
10.3. Dissemination format - online database
There is no online database, but historical figures are available on request.
10.4. Dissemination format - microdata access
There is no microdata access.
10.5. Dissemination format - other
Data is transmitted to Eurostat in the prefixed format.
10.6. Documentation on methodology
There are no national methodological documents available except EBS variable definitions. Statec uses the methodology published in the STS manual.
10.7. Quality management - documentation
There is no document on quality management available.
11.1. Quality assurance
STATEC follows the European code of good practice. There is no specific other quality management concerning this indicator.
11.2. Quality management - assessment

13.1. Accuracy - overall
There is no information available.
13.2. Sampling error
The sample covers around 100 units, which represents around 10% of the statistical population. The coverage rate in terms of share of turnover among the selected units relative to the turnover of the target population is around 80%. There are around 1 300 price quotes that enter the index calculations.
13.3. Non-sampling error
The non-response rate is less than 5%.
14.1. Timeliness
Timeliness and punctuality according to the EBS regulation.
There is a timeliness of m+45 days: Data for reference month m are published the 15th of month m+2.
14.2. Punctuality
See 14.1.
15.1. Comparability - geographical
The whole territory is covered. There is no measurement of the impact of differences in applied statistical concepts.
15.2. Comparability - over time
Weights and samples are updated every 5 years. The last revision took place in 2024 (base year 2021).
15.3. Coherence - cross domain
In LU, there are no other price statistics concerning industrial output. Comparisons with other statistical products such as consumer prices or agricultural prices concerning methodology, concepts or results are not straightforward.
No formal comparisons were made with the main complementary statistics
15.4. Coherence - internal
The unit in charge of this indicator tries to achieve a high level of coherence within the given data set (e.g. sub-aggregates / aggregates, etc.)
The following cost and burden covers both national and European needs:
Costs NSI : 405 hours/year
Burden KAUs: 491 hours/year
17.1. Data revision - policy
In the field of EBS, Statec has no official release or revision calendar. Data dissemination depends on the deadlines foreseen in the EBS regulation. Revisions are made each time whenever, completed or corrected figures are available. The revised results are used for national releases as well as for the data transmission to Eurostat. Users are only informed about the reasons of non-scheduled revisions if the revisions are considered to be important. Different versions of historical data are not stored, only the last available version is saved. Nevertheless, LU plans to introduce the storage of the different versions of released data, but this project is depending on the availability of resources. The base year remains unchanged for five years as stated in the EBS regulation. After changing the base year according to the EBS regulation, LU publishes results according to the new base year = 100 which is indicated in the publications. EBS statistics are confronted with quarterly national accounts and, if necessary, corrected.
17.2. Data revision - practice
In the field of EBS, revisions are made each time when newer, completed or corrected figures for the different variables are available. There is no official revision calendar or regular process. The data and level of revisions depend on the data available. It is impossible to quantify the expected average size of revisions, for the same reason, users cannot be informed in advance of major revisions.
For several reasons, data can be updated after the first release of results: availability of corrected or completed data, correction of methodological or technical errors, confrontation with QNA data, etc.
Prices are provided monthly by KAUs by a specific survey. Questionnaires are transmitted to Statec by e-mail.
In the case of the industrial producer prices, there is no utilisation of administrative data.Additional sources are used for the weights (SBS, business register):
18.2. Frequency of data collection
Monthly survey on producer prices in industry
18.3. Data collection
Data is transmitted to STATEC by e-mail. Data is checked before the electronic processing (completeness, logical errors, high deviations from the normal level, etc.).
18.4. Data validation
The following data checks are performed: • Checking the largest price increase and decrease within an enterprise • Checking the largest impacts on the resulting indices • Comparing the results with previously published figures
Missing informations are imputed according to a set of internal rules by using figures of comparable months for the same KAU or other KAUs in a comparable activity branch.
18.5. Data compilation
Missing informations are imputed according to a set of internal rules by using figures of comparable months for the same KAU or other KAUs in a comparable activity branch.
A fixed base price index is used, with weights from reference year 2021 and base price equal to the average monthly price of 2021. Explicit weights are defined down to the product level. When products are replaced, indices are linked by defining a new base price for the new product. If there is need to slightly adjust samples, weights are adjusted accordingly.
18.6. Adjustment
There is no specific adjustment for this indicator
No further comments.
The industrial producer price index is a monthly short-term indicator used for the business cycle analysis and for the deflation of production values.
