• 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.

There is no general datasharing

STATEC guarantees the non-disclosure of confidential information when the statistical results are disseminated, except for foreign trade statistics. Regarding the latter, the detailed data that allows a resident exporter or importer to be indirectly identified is only kept confidential if the concerned economic operator sends a request for this to STATEC.

The ESS confidentiality rules are applied.

There is no official national release calendar.

There is no official national release calendar.

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.

Quarterly statistical newsletters on industrial production announce the quarterly results.

There is a monthly transmission to Eurostat according to the delays of transmission foreseen in the EBS-Regulation.

News release available in paper format and on internet. It is also transmitted to the media and the registered users.

Monthly publication "Indicateurs rapides B1" available on internet and in paper format.

Historical data are available on LU's statistical portal.

There is no microdata access.

not available

There are no national methodological documents available except STS variable definitions. Statec uses the methodology published in the STS manual.

There is no document on quality management available.

The European Statistics Code of Practice is applied.

The statistics are compliant in terms of :

• Relevance
• Accuracy and reliability
• Timeliness and punctuality
• Coherence and comparability.

There is no information available on supplementary user needs.

A Supreme Council of Statistics is set up by the Minister appointed to economic affairs and its members are chosen from the users and providers of statistical data.
The Council carries out consultative functions at STATEC and may give its opinion on the work and decisions of the Committee on Public Statistics. It issues proposals for the drawing up of statistics of general interest and for improving the statistical work of the national statistical system.

There is no specific information on user satisfaction.

LU does produce all the level of details requested by the EU legislation.

There is no information available on the accuracy of these statistics.

There is no information available on the accuracy of these statistics.

There is no information available on the accuracy of these statistics.

Questionnaires are sent every month to the reporting units. the reporting units have 20 days to send their replies. There is no difference  between the different aggregation levels (Total, MIGs, special aggregates, NACE Sections, Divisions, Groups or Classes).

Released were delivered on time

Statistics produced according to European guidelines.

Statistics are comparable over time according to European guidelines.

No reconciliation is perfomed.

The unit in charge of STS tries to achieve a high level of coherence within the given data set (sub-aggregates / aggregates, unadjusted/adjusted time series, etc.)

NSI: 1400 hours/year

KAUs: 230 hours/year

The first release of the industrial production index is an estimate and is published 40 days after the end of the reference month. The second release, 60 days after the reference month, can be considered as partly definitive. Data on industrial production are not revised according to a specific calendar, but each time when newer, completed or corrected figures are available. In case of detected errors, data is updated at any time. Users are only informed about the reasons of non-scheduled revisions if these are important.

The same revision policy is applied to data released nationally and sent to Eurostat.

Generally, 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 when newer, completed or corrected figures are available. The revised results are used for national releases as well as for the data transmission to the European Commission. 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 STS 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.

Revisions are made each time when newer, completed or corrected figures for the different variables are available.

For several reasons, data can be updated: late arrival of data, availability of corrected or completed data, correction of methodological or technical errors, confrontation with QNA data, etc.

It is impossible to quantify in advance the expected average size of revisions, for the same reason, users cannot be informed in advance of major revisions.

At present, different versions of historical data are not stored, only the last available version is saved in the STS database. Nevertheless, LU plans in the future to introduce the storage of the different versions of released data.

Calculations (2020-2022) based on vintage figures transmitted by EUROSTAT to STATEC:

MR: 0.572
MAR: 3.639

Raw data are provided monthly by survey. It is transmitted to Statec by post or e-mail.

In the case of the industrial production index, there is no utilisation of administrative data.

monthly survey on industrial activity

collection by paper or EXCEL questionnaire, replies by e-mail, fax or post mail.

Data is checked before the electronic processing (completeness, logical errors, sums etc.). The data processing tool has some integrated tests helping to detect errors (e.g. average product prices deviating from the normal level). After the index calculation, the indices are visually checked: Statec uses a EXCEL graphs and outlier detection programs.

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.

Industrial production indices are calculated by using production volumes expressed in physical units (kg, liters, square meters, etc.) or in deflated values. The chosen deflators are industrial PPIs for the same or comparable products produced by the same or comparable KAUs.

Adjustment is carried out using the JDemetra+ . In automatic model selection, LU uses the national calendar (2 regressors) with leap year adjustment and without correction of the Easter effect.

Outliers are automatically detected (additive ouliers, temporary changes, level shifts). The models and the respective parameters are re-estimated once a year. The revisions of seasonnally adjusted series depend as well on the technical choice (model, parameters, etc.) as on the revision policy of raw data.
