<?xml:namespace prefix = st1 />Art. 2. of the Law of 10th July 2011 states that STATEC's remit is:
to set up a statistical information system accessible to the public, in particular on the structure and the activity of the country by drawing up, through surveys or using administrative files, statistics concerning notably demographic, economic, social and environmental phenomena and also by centralising the statistical data available from public bodies by reason of their powers;
to draw up national, global or sectoral accounts;
to draw up, jointly with the Central Bank of Luxembourg, the balance of payments and the financial accounts and to guarantee their methodological consistency in accordance with European and international rules, the terms and conditions of the collaboration being the subject to an agreement between the Government and the Central Bank of Luxembourg;
to set up and manage a "Central Balance Sheet Data Office" consisting companies' annual accounts data and to publish the information thereof;
to carry out population, housing and buildings censuses, their date and terms and conditions being enacted by a Grand-Ducal regulation;
to carry out studies and analyses in the field of statistical methodology and statistical procedures and to publish relating resultsto gather general documentation concerning statistics, as well as demographic, economic and social theories and facts;
to represent Luxembourg as its the national statistical authority at foreign, EU and international statistical authorities.
Art. 4. announces that without prejudice to the special powers assigned by law to other public bodies, STATEC is also in charge of:
drawing up short- and medium-term global or sectoral economic forecasts and, where applicable, providing technical assistance in drawing up such forecasts. To this end, STATEC develops or contributes to the development of statistical and econometric tools, in particular macroeconomic models used for drawing up these forecasts adapted to the specific features of the country and complying with prevailing international standards;
drawing up long-term global or sectoral economic, social and demographic projections and, where applicable, providing its assistance in elaborating such projections;
studying short term economic movements as well as structural changes in the economy and publishing the results of these studies;
carrying out general or special economic, demographic, social and environmental studies and analyses and publishing relating results;
carrying out scientific research on the modelling of economic, demographic, social and environmental facts and publishing relating results.
Within its remit and subject to the approval of the Minister appointed to economic affairs and with the inter-ministerial coordination committee for research and technological development asked for its opinion on each project, STATEC is authorised to undertake R&D activities in accordance with the provisions of section I of the law of 9 March 1987, the purpose of which is 1. the organisation of research and of technological development in the public sector and 2. the transfer of technology and the scientific and technical cooperation between companies and the public sector.
STATEC is authorised to publish any studies or research work which contribute to the scientific analysis of the Luxembourg economy and society.
Data produced by STATEC are disseminated as a service to the public.
Art. 3. of the Law of 10th July 2011 states that STATEC ensures the coordination of the national statistical system in consultation with the Committee on Public Statistics. It ensures the harmonisation of the statistical methods, definitions and nomenclatures and sees to the application of relating European and international standards
Art. 12. of the Law of 10th July 2011 affirms that in order to limit the number of surveys, the transfer and exchange of data between the components of the national statistical system are authorised in accordance with the terms and conditions determined within the Committee of Public Statistics.
Art. 16. of the Law of 10th July 2011 affirms that 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 data used to produce the statistics is deemed confidential when it allows an individual or legal entity to be directly or indirectly identified or comprises a risk of disclosure of individual information. To determine whether an individual or legal entity is identifiable, account shall be taken of all relevant means that might reasonably be used by a third party to identify such individual or legal entity. However, data which is taken from sources accessible to the public and which remains accessible according to legislation is not considered confidential. The same applies when express authorisation from the provider of statistical information is given.
When the fulfilment of its remit or the statistical aims sought require the use of data from identifiable statistical units, this data is processed by respecting the fundamental rights and liberties of the concerned individuals or legal entities. Only the people responsible for drawing up these statistics have access to this data. As soon as the identification of the statistical units and in particular of individuals is no longer necessary in the statistical production process, the data will be made anonymous.
For scientific purposes, STATEC may grant access to confidential data on its premises. The admissibility of the request for and the authorisation of access to the confidential data for scientific purposes are subject to the assessment of the merits and the scientific interest of the research projects for which the authorisation is requested, and also to the assessment of the scientific qualification of the applicant(s). The terms and conditions of access are determined by STATEC. The studies and results of the research that are likely to be published or disseminated are checked by STATEC to avoid the disclosure of confidential data.
Information that can be individualised cannot, under any circumstances, be disclosed.
The civil servants and those persons responsible for collecting the information or cooperating with the statistical work are personally responsible for strictly complying with the provisions above; Article 458 of the Criminal Code is applicable to them, without prejudice to any disciplinary sanctions.
The provisions of this article apply by analogy to other organisations that form part of the national statistical system.
Art. 17. of the Law of 10th July 2011 announces that the information collected can only be used for statistical purposes, i.e. exclusively for the drawing up of statistics or statistical, economic and social analyses and studies.
It cannot induce administrative, legal or tax use or in the checking of respondents, unless these respondents have unequivocally given their consent to the data being used for such purposes.
Art. 13. According to the Law of 10th July 2011 public administrations, municipalities and public institutions as well as all individuals or legal entities are obliged to provide the statistical information requested by STATEC within preset deadlines.
Unless stated explicitly as voluntary, any request for information by STATEC is compulsory and is based on the national statistical programme or on European and international statistical programmes.
Within the remit stated in Article 2, STATEC has a right of access to the information, even individual information, contained in the files and databases of administrations and public services, collected as part of their administrative powers.
To draw up the statistics on road traffic accidents, STATEC is provided with the reports issued when accidents involving bodily injury occur. The processing of data only relates to the facts associated with the accidents, excluding any personal data.
Art. 14. If the statistical obligation mentioned in Article 13 is not complied with, the investigation department has a right of investigation exercised by STATEC's agents or representatives; with a mandate issued by the director of STATEC, they can ask for access to the statistical information when it is not provided within the time frames set or if it becomes necessary to check its accuracy.
The employees or agents responsible for directly collecting the information may request the assistance of the administrative authorities.
Art. 15. Refusing to provide the information requested, refusing to provide it in the prescribed time frame and intentionally providing inaccurate or incomplete information is liable to a fine of between 251 euros and 2,500 euros. Paying the fine does not waive the provision of the information requested.
Art. 8. According to the Law of 10th July 2011, a Committee on Public Statistics is established by the Minister appointed to economic affairs.
The Committee is made up of representatives of administrations, ministries, public institutions and observatories set up by the public authorities drawing up and disseminating statistics or, by reason of their powers, holding data used or usable for drawing up statistics.
The Committee's remit is:
to coordinate the statistical programmes of the various administrations, ministries, public institutions and observatories and to monitor these programmes in order to improve efficiency and quality, to alleviate the overall response burden and to comply with European and international obligations within prevailing deadlines;
to analyse the users’ needs of statistics and of economic, social and environmental analyses;
to give its opinion on any draft regulation that might have repercussions on the national statistical system;
to give its opinion on any proposed statistical survey by private organisations to be carried out by using government grants.
The Committee is chaired by the director of STATEC. It has the administrative and technical support of STATEC.
A Grand-Ducal regulation specifies the composition of the committee and decides on its organisation and mode of operation.
Art. 9. of the Law of 10th July 2011 states that 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.
The composition, organisation and operating mode of the Supreme Council of Statistics and the compensation scheme of its members are determined by a Grand-Ducal regulation.
Independence and scientific rigour, quality charter, code of practice, constitute STATEC's pledge to provide only the best statistical information. Having always drawn up its results in accordance with best practice, international collaboration, particularly within the European Union, has improved data quality. Quality is understood in the widest sense. Accuracy in collection procedures and mathematical processing is only one aspect of quality. There are others:
To achieve this aim, STATEC emphasises dialogue and external auditing. Its activities and work programme are analysed and assessed within the Supreme Council of Statistics.
The IMF SDDS dissemination standard
Since 12 May 2006, STATEC's economic and financial indicators comply with the International Monetary Fund's dissemination standard. Luxembourg is the 64th member.
The SDDS provides a series of rules on the number and quality of economic and financial indicators, publication deadlines and the manner in which these indicators are documented.
Art. 11 of the Law of 10th July 2011foresees that STATEC establishes its own Statistics Code of Practice that meets European and international requirements and standards. This codewill beaccessible to the public.
Each department (Statec has 5 departments) describes its operational objectives for the coming year. Statistical production is almost completely regulated by the EU-framework, a national medium term programme is largely defined by Eurostat’s annual and 5 year programme. Each department is responsible for the quality monitoring of its programme.
See 0.4.2
Art. 11. of the Law of 10th July affirms that STATEC is endowed with scientific and professional independence, in carrying out its remit defined in Article 2 and Article 4, paragraphs 2 and 4,.
The director of STATEC decides on the statistical methods, standards and procedures as well as on the content and the date of dissemination of the statistical publications. Within the limits of available resources he can command any other urgent survey, study or research not included in the work programme.
Statistics are drawn up and statistical sources and techniques are chosen according to statistical considerations.
The statistical methods and procedures used are documented and take account of scientific standards recognised in Europe and internationally. The documentation concerning the statistical methods and procedures used is made available to the public.
Notice is placed on questionnaires informing on the purpose and conditions of the data collection.
According to Art. 12. of the Law of 10th July 2011, in choosing a method of data collection, STATEC favours the use of administrative files. It only resorts to surveys or censuses if the use of administrative files is impossible or is not likely to provide reliable and relevant statistical information.
In order to limit the number of surveys, the transfer and exchange of data between the components of the national statistical system are authorised in accordance with the terms and conditions determined within the Committee of Public Statistics.
STATEC appropriately informs those responsible for providing the statistical information about the underlying objectives.
There is no ministerial comment on the occasion of the release of the data
Some government officials have access to the data prior to their simultaneous release to all interested parties.
A special Index Committee, called Commission de l'indice des prix à la consummation, meets monthly at STATEC. It comprises the principal social partners (labour unions and employers' federations), one representative from the Ministry of Economy, experts and one member of the Central bank of Luxembourg (Banque centrale du Luxembourg) as observer. The task of this committee is to issue opinions on all problems relating to the national consumer price index and to officially validate the monthly figures. Every month, it examines retail prices recorded and indices constituting the index and gives an opinion. The members of the Index Committee receive all data 3 to 4 days before the meeting, which is immediately prior to the dissemination of the monthly figures.
Publication of statistical products are generally accompanied by news identifying the units and contact persons responsible for further information.
Major changes are often announced at the same time statistical outputs are released. However these changes impact other bodies, e.g. classification according to NACE, these bodies are informed in advance allowing them to adapt to the foreseen changes
Revisions in methodology are announced to the public, usually with the publication of the figures.
Guidelines are handed over to new employees having to read and sign these documents.
Analytical framework: Measure of changes in the retail prices of a fixed set of goods and services consumed by households on the national territory. The National Consumer Price Index (NCPI) relates to the consumption of resident households on the national territory whereas the Harmonized Consumer Price Index (HICP) is based on the whole consumption expenditure (residents as well as non residents) on the national territory.
Definition: Both Consumer Price Indexes calculated in Luxembourg are annually chained Laspeyres-type indexes (with the index reference period 2015=100). The entire methodology for the HICP, as well as for NCPI, is based on the European regulations governing the HICP (See hereafter).

Index compilation follows the standards of the internationally accepted statistical methodology as presented in (CPI Manual 2004) - Consumer Price Index Manual: Theory and Practice 2004 (ILO, IMF, OECD, Eurostat, United Nations, and the World Bank)
Population coverage: HICP covers all private households in the economic territory irrespective of income or activity, including persons living in institutional households. The measure of the consumption expenditures of foreign households, their distinction from business expenditure, and the measure of domestic household consumption expenditure abroad are made according to the concepts and methods of National Accounts.
Geographical coverage: The HICP covers the entire area of the country. Prices are collected in a sample of about 680 outlets spread over the whole territory of the country. Considering the small size of the country there is no further division of the territory for the need of the price collection. The prices are mainly collected in the largest urban centers.
Item coverage: The prices of about 8000 consumer goods and services on average per month are surveyed in about 680 outlets. They are classified in the 12 COICOP divisions below listed below:
Nr. of price observations per month and per major group (COICOP divisions):
01 Food and non-alcoholic beverages 1760
02 Alcoholic beverages, tobacco 279
03 Clothing and footwear 581
04 Housing, water, electricity, gas and other fuels 851
05 Furnishings, household equipment and routine maintenance of the House 968
06 Health 445
07 Transport 494
08 Communication 209
09 Recreation and culture 958
10 Education 61
11 Restaurants and hotels 602
12 Miscellaneous goods and services 757
The divisions are further sib-divided into groups (3-digit) , classes (4-digit) and sub-classes (5-digit). The classification is aligned on the European – COICOP5.
The six-digit level is the lowest level containing 309 elementary aggregates.
Below this level no further distinction is made between “Representative goods and services” and the “items” representing those goods and services. The following list indicates the number of elementary aggregates in every COICOP division.
Number of elementary aggregates per COICOP division (reference year 2015):
01 Food and non-alcoholic beverages 70
02 Alcoholic beverages, tobacco 11
03 Clothing and footwear 38
04 Housing, water, electricity, gas and other fuels 20
05 Furnishings, household equipment and routine maintenance of the House 40
06 Health 12
07 Transport 29
08 Communication 6
09 Recreation and culture 45
10 Education 4
11 Restaurants and hotels 10
12 Miscellaneous goods and services 24
Owner-occupied housing: At present owner-occupied housing is not included in the CPI. A separate price index for owner-occupied housing based on the net acquisition approach is compiled starting in 2010.
Classification: Both CPIs (NICP and HICP) are covering the categories of the Revised European COICOP-classification (a standard system from the United Nations for the classification of individual consumption by purpose adapted to the needs of the HICP).
Types of prices: The prices collected try to stick as much as possible to the real transaction prices paid by the consumers including taxes like VAT or Eco-taxes less any discounts or rebates when those are identifiable. Sales prices are also taken into account. Some prices are not directly observed in shops such as prices for package holidays and cars which are collected from catalogues or from the internet.
Timing of price observations: The frequency of data collection is monthly. All the prices are collected between the 1st and 21st of each month.Prices for car fuel, heating fuel and gas are recorded daily from the 1st to the21st of each month.
Sources of weights: The weights used in the index are annually updated and derived from national accounts (NA) final private consumption data. Household Budget Survey results are integrated in the NA results. There are presently 309 item weights at national level at the lowest level of aggregation.
Time period of current weights: The present weight reference period (for Y=2017) is the year 2015, these weights are updated by December Y-1 prices (December 2016 for Y=2017).
Frequency of weights updates: The frequency of weights update is annual. The weights scheme is annually fixed for the next 12 month by a national regulation after consultation of the social partners.
Item selection: The selection of representative goods and services and the items representing them is based on the offer of the outlets. The products to be priced are selected by the consumer price unit’s staff, based on their experience and knowledge, where necessary, in collaboration with the outlets or the service providers. As well market studies are used when existing or in some cases basic studies are executed by Statec itself.
Outlet selection: Given the small size of the country, the sample is designed to cover in principle all outlets of national or more than local importance. For a limited number of items, mainly food, where the number of existing outlets is higher, outlets of local importance are included in the main towns. Different sizes and various types of outlets are covered like for instance traditional shops, supermarkets, big trade centers, petrol stations, restaurants and hotels. The outlet sample is updated continuously on the basis of price collectors’ experience and knowledge of the local market.
Sample sizes: About 680 outlets in the country are chosen for the survey and an average of 8000 products and services are priced monthly.
Data collection: The techniques of price collection are variable and individually adapted. Price collection for goods is in general made directly in the outlets, other prices are obtained centrally and collected by telephone, fax, e-mail, post and via internet (mainly for rents, prices for cars, tariffs for postal services, trains and buses, banking, electricity, gas, health, etc.).
The price collection is made by the permanent staff of the national statistics institute (Statec). Electronic devices for price collection have been introduced in 2017.
Item/product specification: Product specifications are of the narrow type, including specifications about the brand, the model, the unit, the materials and other characteristics. The accuracy of the specification depends on the nature of the product or service.
Treatment of missing prices: Missing items and their replacements are treated according to Commission Regulation (EC) no 1749/96.
If a price observation is missing, then the missing price is allowed to be estimated for the next two months. After a two month estimation period the product is replaced in the same outlet. In case of a replacement, the price of the new product for the previous month is included if known or it is estimated by methods such as “Bridged Overlap”. According to this method the price estimation is based on the price dynamics of similar products within the same product group.
Procedures are applied on a case by case basis.
Selection of replacement items: the product is replaced with a representative replacements belonging to the same consumption segment in the same outlet, based on the experience of the price collector and where necessary, in collaboration with the outlets or the service providers.
Adjustments for quality differences: Quality adjustments are made according to Commission Regulation (EC) no 1749/96. The methods implemented are chosen according to a case by case approach. At the present time no hedonic methods are used.
Price adjustments due to quality changes are most frequent for cars, electronics (computers, televisions...) , clothing and other technical products.
Introducing new products: New goods and services detected in the outlets by price collectors or reported to be significant in other Member States are included in the relevant elementary aggregate in December of the year during which their presence on the market has shown their significance.
Seasonal items: Seasonal products (fruits, vegetables, clothing and shoes) are treated according to regulation 230/2009. More particularly, an all-seasonal estimation method is used for these items.
Verification of processing: Results are assessed at various stages of the compilation process.
Seasonally-adjusted indices: none
Computation of lowest level indices: All individual prices collected are transformed to indices with base 100 = December of previous year. The indices of the elementary aggregates (basic groupings) are obtained by calculating for every aggregate the geometric mean of the indices of that elementary aggregate. The unweighted geometric mean is used for all elementary aggregates.
Aggregation: The aggregation formula used is ofLaspeyres type. Indices of basic groupings are aggregated according to the subdivisions of the revised COICOP classification. The Luxembourg consumer price index is, since 1999, an annually chained Laspeyres-type index.
Alignment of expenditure and base period: The weights reference period for the year Y is the year Y-2, these weights are updated by the December Y-1 prices. For instance, weights for 2015 are based on the National Accounts of the year 2013 updated with the December 2014 prices.
Linking reweighted index to historical index: The process for linking of the re-based index after a weight update to the old series is achieved through the chain index. In a chain index each link consists of an index in which each period is compared with the preceding one, the weight and price periods being moved forward each period.
Reference period: The index reference period was 1996=100 for all indices and sub-indices until December 2005. From January 2006 on, the index reference period is set as 2005=100. From the 1st January 2006,according to European regulation, the base year is set as 2005 (2005=100). From the 1st January 2016, according to European regulation, the base year is set as2015 (2015=100).
Verification of prices: All price notations of the month are individually controlled at different stages of the survey, and checked in case of doubts. Price collectors have to provide reasons for large price changes using a system of flags.
If the difference between the T and T-1 prices exceeds an indicated threshold the software requires an additional check of the data. The database also includes different types of queries allowing to detect possible errors (for instance a query producing a table showing the maximum and minimum price change of the products over a period). Replacements are also monitored. Finally resulting sub-indices are ordered according to their contribution to the overall result.
If there are still doubts about the reliability of one or more prices, these prices are checked once again by contacting price collectors or if necessary, checked directly in the outlets.
The monthly HICP (as well as the NICP) indices are published generally between the second and the ninth day of the month following the reference month.
Results are internally consistent in the sense that the all-items index is an aggregation of the individual sub-series.
There exists a long term series going back to January 1948. Over the years, the coverage and methods have been changed.
Figures are final when first released and are not subject to revisions. Corrections are made exceptionally when errors have subsequently been ascertained in the calculations.
The provisional, revised or final nature of the data is not indicated in the publication at the time of release.
Two versions of the CPI are disseminated in Luxembourg: the national consumer price index (NICP) and, as in other European Union countries, the harmonized consumer price index (HICP). The NICP described here differs from the HICP by the only fact that it does not take into account the consumption of non-residents on the national territory.
Monthly results available on the statistical portal (“Serie A1” for the NICP and “Serie A1 bis” for the HICP)
Press releases are available in French
An advance release calendar specifying the precise date ofdissemination at least three month in advance for all the above data is published by Statec.
The data are simultaneously made available to all interested parties on the scheduled day of release on the Statistics Portal of Luxembourg under the following section (“Serie A1” for the NICP and “Serie A1 bis” for the HICP).
Because the methods used for producing the HICP and the NICP are identical, methodological notes concerning the HICP are not published while for the NICP a methodological description is published in:
Bulletin du Statec No 2/2003: Indice des prix à la consommation – Développements méthodologiques de 1990 à 2003,published in French
The consumer price index data are produced according to the methodology specified in:
Council Regulation (EC) No 2494/95 of 23 October 1995 concerning harmonized indices of consumer prices and subsequent Council / Commission regulations laying down detailed rules for the implementation of Council Regulation No 2494/95.
