The labour cost index is compiled every quarter, and is published no later than 70 days after the end of each quarter.The published figures may be revised by changes in labour cost survey.

Collected and revised data are stored securely by Statistics Norway in compliance with applicable legislation on data processing.

Statistics Norway can grant access to the source data (de-identified or anonymised microdata) on which the statistics are based, for researchers and public authorities for the purposes of preparing statistical results and analyses. Access can be granted upon application and subject to conditions. Refer to the details about this at Access to data from Statistics Norway.

The background of the labour cost index is the need for more timeliness in the measurement of changes in labour costs. The purpose is therefore to show changes in labour costs through the year.

The index was published for the first time for the third quarter of 2004, with back indices to the first quarter of 1998.

From 1st quarter 2009 Statistics Norway has introduced a new version of Norwegian industry classification (SIC2007). This new classification provides a more suitable and updated description of the activity concerning both the private and public sectors, with more focus on service industries.

The early time series of Labour cost index for the period from 1st quarter 2000 to 4th quarter 2008 are therefore recalculated based on SIC2007. Time series in accordance with SIC2002 will not be published as from January/first quarter of 2009, but will be available in StatBank.

The labur cost index was revised in the publication of fourth quarter 2009 and 2018, due to the results in the labour cost survey 2008 and 2016.

The principal users of the labour cost index will be Eurostat, the Technical Reporting Committee on income Settlement , Statistics Norway's National Accounts and business.

No external users have access to the statistics and analyses before they are published and accessible simultaneously for all users on ssb.no at 8 am. Prior to this, a minimum of three months' advance notice is given in the Statistics Release Calendar. This is one of Statistics Norway’s key principles for ensuring that all users are treated equally.

The development in the labour cost index will tally with the development in wage-cost totals in the National accounts and the labour cost survey.

Indices for other countries in Europe are presented by Eurostat

The statistics are developed, produced and disseminated pursuant to Act no. 32 of 21 June 2019 relating to official statistics and Statistics Norway (the Statistics Act).

Council regulation (EF) nr. 450/2003 of 27 February, concerning short-term statistics on labour costs.

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 statistics (EBS-Regulation)

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)

The population covers all the establishments in Statistics Norway's Central Register of Establishments and Enterprises, industrial groups B to S, according to Standard Industrial Classification.

The labour cost index is obtained by putting together Quarterly Wage Index , Structural Statistics on Wages , The Labour Cost Survey and wage totals from The Register of End of the Year Certificate.

Until 2015:

The labour cost index is carried out within the frame work set by the data sources. The units included in the statistics are consequently limited to those units included in the quarterly wage index, annual wage statistics, the labor cost survey and wage totals from The Register of End of the Year Certificate.

From 2015:

The statistics is based on full cencus data from a-meldingen. More about A-meldingen

The labour cost index has no data collection of its own.

Editing is defined here as checking, examining and amending data.

The indices are checked against historical series and are compared with the published statistics from the data sources.

The labour cost index is a Laspeyres index with fixed weights. The labour cost index is constructed as a sum of sub-indices for cost components constituting total labour costs. Changes in labour costs are estimated and then weighted together to obtain a labour cost index, where weights are based on information from the labour cost survey.

The index is an unadjusted index. It is neither working day nor seasonally adjusted. This means that the index shows changes in labour costs per hour and that variations in the number of working hours or days between the quarters do not affect the index in the present quarter.

Not relevant

Employees of Statistics Norway have a duty of confidentiality.

Statistics Norway does not publish figures if there is a risk of the respondent’s contribution being identified. This means that, as a general rule, figures are not published if fewer than three units form the basis of a cell in a table or if the contribution of one or two respondents constitutes a very large part of the cell total.

Statistics Norway can make exceptions to the general rule if deemed necessary to meet the requirements of the EEA agreement, if the respondent is a public authority, if the respondent has consented to this, or when the information disclosed is openly accessible to the public.

More information can be found on Statistics Norway’s website under Methods in official statistics, in the ‘Confidentiality’ section.

Statistical releases older than 6 June 2017.

The labour cost index was produced for the first time with figures for the third quarter of 2004 and is comparable back to 1998 for all the economic activities covered.

From the 1st quarter of 2009 Labour cost index publishes in accordance with SIC2007 and the reference value changes to the average of the quarters in 2005, such that 2005=100.

The index values are comparable only within the same version of Standard Industrial Classification .

Measurement errors
Measurement errors in the labour cost index relate to the possibility of inconsistencies between the data sources with respect to the definitions of variables.

Processing errors
Processing errors in this connection, relate to the utilization of the data material from the data sources in a homogeneous way.

The labour cost index is not encumbered by sample bias of its own.

Register errors
Every source of data is linked to industry code in Statistics Norway's Central Register of Establishments and Enterprises. Incorrect information in the register my result in industrial misclassification of units.

Model errors
The labour cost index is constructed by putting several statistics together, where weights are used to weight the statistics. The way in which this weighting is built up is a source of model error.

Coverage errors
One model assumption is that the data sources reflect the true distribution of the population, respecting units, variables and labour cost components.

From 2015 the statistics is mainly based on data from a-meldingen. Here also, observations can be discarded due to missing information and/or incorrect values for the variables.

A revision is a planned change to figures that have already been published, for example when releasing final figures as a follow-up to published preliminary figures. See also Statistics Norway’s principles for revisions.

Revisions in previously published seasonally adjusted figures can take place when new observations (or revised previous observations) are included in the basis of calculation. The scope of the revision is usually greatest in the most relevant part (last 1–2 years) of seasonally adjusted time series. A corresponding revision in trends is also typical, particularly at the end of the time series. The extent of the revision of trends and seasonally adjusted figures is partly determined by the revision policy, see Section 4 of the European Statistical System (ESS) Guidelines on Seasonal Adjustment on the Eurostat website. For more information on the revision of seasonally adjusted figures, see the ‘About seasonal adjustment’ section in the relevant statistics.

The published figures may be revised by changes in labour cost survey which is conducted every fourth year.

Preliminary figures will be final when the statistics on labour cost survey is published.

The labur cost index was revised in the publication of fourth quarter 2018, due to the results in the labour cost survey 2016.
