Labour cost index: documentation of statistics
Basic data of the statistics
Data description
Statistical presentation
In the index, hours worked or the structure of personnel have not been standardised. The cost of an hour worked is calculated directly as the ratio of industry-specific wages and salaries subject to preliminary withholding tax and social insurance contributions to the hours worked for each quarter. The change in average labour costs is affected by changes in regular earnings, performance-based bonuses and other one-off pay components, social insurance contributions, as well as changes in the number of hours worked and the structure of the labour force.
Starting from the first quarter of 2019, the wages and salaries sum of the labour cost index is based on the Incomes Register. The wages and salaries sum is used to raise the labour costs reported by the data providers to the industry level.

Sector coverage
The statistics cover the private and public sectors almost in their entirety. Agriculture, forestry and fishing are excluded from the statistics. Since 2007, the basic data of the statistics in terms of the private sector have been collected with a sample comprising more than 2,000 enterprises. The central government has supplied basic data in terms of the entire central government since 2007. In the local government sector, the data were collected from 2008 to 2010 in the municipalities in Greater Helsinki, and from 2011 onwards, from the biggest municipalities, with more than 50,000 residents, and the biggest joint municipal authorities. As of the beginning of 2012, data have also been collected by random sampling from selected municipalities with fewer than 50,000 residents. As of the beginning of 2023, the quarterly data collection applies to all municipalities with a population of over 50,000, a sample of municipalities with fewer than 50,000 inhabitants, as well as the largest education consortia and joint parishes. The data collection also includes all wellbeing services counties and joint county authorities for wellbeing services.

Base index
Bonuses and allowances not paid in each pay period
Structural statistics on wages and salaries:
Holiday supplement paid for days off not taken is not included in these bonuscomponents in the structural statistics on wages and salaries.
Index of wage and salary earnings:
The index of wage and salary earnings measures the development of earnings from regular working hours regardless of the mode of payment. Components paid on the basis of performance are included in the earnings concept so that they are divided evenly over the whole calendar year. Similarly, bonuses and allowances not paid in each pay period based on collective agreements are evenly divided for the whole year. All these components belonging to the concept of index of wage and salary earnings, such as holiday bonuses are not included in data on wages and salaries used in the calculation of the index, but they are taken into consideration in index calculation only in case changes in their relative share are agreed in collective bargaining. In the index of wage and salary earnings contractual pay increases paid retrospectively are also taken to the quarter when they were earned.
Labour cost survey:
In the concepts of the labour cost survey compensations for termination of an employment relationship belonging to bonuses and allowances not paid in each pay period are included in social costs.
Labour cost index:
In the labour cost index bonuses and allowances not paid in each pay period also include contractual pay increases paid retrospectively from previous pay periods. The labour cost index also contains incentive stock options according to their exercise value.
------
Bonuses and allowances not paid in each pay period are not published in the statistics on private sector and local government wages and salaries. These components are not included in the index of regular earnings.
Chain index
At times the chain index is also mentioned in such cases where the comparison period is retained fixed in comparisons within the year, but the comparison period and the weight structure of the index is changed whenever the year changes.
Employer sector
The classification used in statistics on wages and salaries has the following structure:
Local government sector
Operating units of municipalities and joint municipal boards, and municipal enterprises
Central government sector
Agencies and institution financed from the State budget
Private sector
Private enterprises, enterprises with central or local government majority holding and state enterprises. Non-profit corporations, parishes, and organisations and foundations are also included in the private sector in statistics on wages and salaries.
The structure of the classification of sectors used in statistics on labour costs and in the labour cost index is similar to that of the classification used in statistics on wages and salaries.
In the index of wage and salary earnings, non-profit corporations, parishes and organisations form a separate employer sector of their own (Others).
Hours paid
Index formula
Index of wage costs
The wage and salary index, which is part of the labour cost index, measures the change in wage and salary costs calculated per hour worked. Wage and salary costs include all pay and bonuses according to Section 13 of the pre-liminary tax withholding act, thus also costs incurred by payments in kind and incentive stock options.
Labour costs
Total labour costs are obtained by deducting employer's subsidies from the sum of labour cost items. Employer's subsidies are intended for full or partial financing of costs arising from direct compensations paid by the employer. Such subsidies comprise employment subsidies and training compensations paid to employers.
In the labour cost index, labour cost items are grouped as follows:
- remuneration exclusive of one-off pay components
- one-off pay components
- social security costs
In the labour cost survey, labour cost items are divided into the following main groups:
- direct earnings
- one-off pay components
- remuneration for days off
- contributions to personnel funds
- costs of fringe benefits and company products
- social security costs
- training costs
- other labour force costs
Direct earnings refer to wages and salaries paid for hours worked in each pay period. Direct earnings comprise
- direct compensations paid on the basis of hours worked, output produced or amount of work performed
- compensations for overtime, shift work and the like
- additional bonuses and compensations paid regularly in each pay period.
One-off pay components refer to items that are not paid regularly in each pay period. Such bonuses that are often paid only once a year include performance-based bonuses and holiday pay, and seniority increments paid in some hourly paid fields. Payment of one-off pay components can also be based on collectively bargained agreements.
Pay for days off refers to compensations paid for statutory, agreement-based or voluntarily granted leaves, national holidays or other paid days of leave. Typical items of this group are pay during annual holiday entitlement, monthly paid employees' pay during national holidays, hourly paid employees' compensation during national holidays and days of leave in compensation of shortened working hours.
Payments to personnel funds refer to the sums enterprises may annually contribute to their employees' saving systems, such as personnel funds.
Costs of fringe benefits and company products include all costs incurred by an employer from the goods and services it provides for to its employees. Such goods and services include e.g. company car and subsidised meals, incentive stock options and personnel's recreational and social activities. Own personnel's pay is not included.
Social security costs refer to the sum employers pay for the social security benefits of its employees. Such statutory, agreement-based or voluntary payments include employment pension, social security and unemployment insurance contributions. Additionally, this group comprises as imputed social security funding items pay during illness and parental leave (net, i.e. less compensations paid to the employee by the Social Insurance Institution) and occupational health care costs (likewise, net), as well as compensations arising from the termination of an employment relationship.
Training costs include e.g. costs of professional training services, costs of course participations, fees of instructors hired from outside the enterprise and payments to organisations arranging training. By contrast, pay for the participants during training is not counted as training costs but as pay for hours worked.
Other labour costs include e.g. costs arising from protective and working clothes and from the procurement of labour.
Employer's taxes paid on the basis of the sum of wages and salaries or the employed labour force that the labour cost concept of the European Union contains do not exist in Finland.
The concept of labour costs partly equals the national accounts concept of compensation of employees but exclusive of e.g. occupational health care, training and recruitment costs.

Source data and data collections
Source data
The average unit costs of an hour worked are known to vary to some degree, depending on the size of an enterprise. In terms of size, enterprises are unevenly divided – the expected nonresponse of smaller enterprises is greater and large enterprises cover a great deal of the wages and salaries sum. The sample design aims to ensure that enterprises of all sizes are represented in the collected data. This is why the private sector’s sampling frame is stratified into five size categories depending on the number of salary earners. The determination of a sample’s selection ratios is based on a two-phase square root quota (quota to the power of 0.5). The square root quota aims to ensure results fir for publication at the level of both the national economy and an industry’s main category. The two-phase quota aims to ensure a sample’s optimal allocation to enterprises of different sizes within an industry.

Methods
Data compilation
If there are any obscurities in the data, the respondent will be requested to provide additional information and, if necessary, to correct the data. The data processing is carried out using the labour cost application, and the SAS and SQL tools. When necessary, observations that do not belong in the final statistics (outliers or incomplete responses) are removed from the data.
Data validation
- the quarterly change of the unit cost calculated for an hour worked/paid
- a change in the grounds for determining hours
- the summation of the pay breakdown of the hourly paid
- a change in the tariff of social insurance contributions
- The labour cost of an enterprise’s hour worked/paid without one-off components is compared to the enterprise’s corresponding value from the previous quarter.
- The enterprise’s reference group is determined in accordance with the industry stratum defined for the enterprise.
- Verifying limits are defined for each reference group on the basis of decile division pertaining to the labour costs’ unit change. The change limit corresponding with the first decile (D10) is defined as the lower limit for a change in labour costs. Correspondingly, the change limit corresponding the last decile (D90) is used as the upper limit.
- An observation value remaining within limits is accepted. Observations falling below the lower limit and exceeding the upper limit are marked as deviant and printed out on a control list.

Institutional mandate
Legal acts and other agreements
Statistics Finland compiles statistics in line with the EU’s regulations applicable to statistics, which steer the statistical agencies of all EU Member States.
Further information: Statistical legislation
The labour cost index was developed by order of the European Union as part of a community-wide project. The compiling of the labour cost index is provided for in Regulation (EC) No 450/2003 of the European Parliament and of the Council, and the related Commission Regulation (EC) No 1216/2003 implementing it. The implementing Commission Regulation was amended in terms of the industries it covers by Commission Regulation (EC) No 224/2007. Only the necessary data that are not available from administrative data sources are collected from data suppliers. The index series are published so that the data or development of no individual enterprise, local government, joint municipal authority or central government agency or institution can be deduced from them.

Data sharing
Accessibility and clarity
In addition to statistical data published in the StatFin database, a release on the key data is usually published in the web service. If the release contains data concerning several reference periods (e.g. monthly and annual data), a review bringing together these data is published in the web service. Database tables updated at the time of publication are listed both in the release and in the review. In some cases, statistical data can also be published as mere database releases in the StatFin database. No release or review is published in connection with these database releases.
Releases and database tables are published in three languages, in Finnish, Swedish and English. The language versions of releases may have more limited content than in Finnish.
Information about changes in the publication schedules of releases and database tables and about corrections are given as change releases in the web service.
Data revision - policy
The reason why data in statistical releases become revised is often caused by the data becoming supplemented. Then the new, revised statistical figure is based on a wider information basis and describes the phenomenon more accurately than before.
Revisions of statistical data may also be caused by the calculation method used, such as annual benchmarking or updating of weight structures. Changes of base years and used classifications may also cause revisions to data.
Seasonally adjusted data in statistics on economic trends become revised because of the calculation method used. Additional information on a new time series observation is exploited in model-based calculation methods and this is reflected as changes in previous releases. Revisions of the latest figures to be seasonally adjusted are elaborated on in the releases and quality reports of statistics.
A summary table of the revisions that have taken place is also published in connection with key statistics on economic trends and some annual statistics. The table shows how the data for the statistical reference periods have changed between the first and the most recent statistical release.
