3.1. Data description | |||
Wage and salary indices describe the monthly development of the gross wages and salaries sum in different industries. Sums of wages and salaries refer to the gross totals of wages and salaries enterprises have paid. Wage and salary indices exclude incentive stock options but include bonuses and other one-off reward items. The calculation is based on estimation of change. Calculation of the annual changes also takes into consideration enterprise openings and closures, as well as restructuring and change of activity. The wage and salary indices are based on the Tax Administration's periodic tax return data and the Sales Inquiry of Statistics Finland . Starting from 01/01/2019, the wage and salary indices are based on the Incomes Register data and the Sales Inquiry of Statistics Finland. At the start of the year 2024 the Incomes Register based wages and salaries sum will be allocated according to the earnings period instead of the previous payment-based month. Thus, the wages and salaries sum is better allocated relative to the used labour input. The change will in future cause more index revisions than usual for the most recent month published.

Wage and salary indices describe the monthly development of the gross wages and salaries sum in different industries. Sums of wages and salaries refer to the gross totals of wages and salaries enterprises have paid. Wage and salary indices exclude incentive stock options but include bonuses and other one-off reward items. The calculation is based on estimation of change. Calculation of the annual changes also takes into consideration enterprise openings and closures, as well as restructuring and change of activity. The wage and salary indices are based on the Tax Administration's periodic tax return data and the Sales Inquiry of Statistics Finland . Starting from 01/01/2019, the wage and salary indices are based on the Incomes Register data and the Sales Inquiry of Statistics Finland. Starting from January 2020, data obtained directly from the Incomes Register are used as source data. Previously, the Tax Administration supplied the data to Statistics Finland (http://stat.fi/til/ktps/ktps_2020-06-12_uut_001_en.html) |
|||
3.5. Statistical unit | |||
Administrative source: enterprise. Statistical survey: kind-of-activity unit for the (few) major multi-industrial enterprises. |
|||
3.6. Statistical population | |||
The population of wage and salary indices is all employers that pay wages and salaries. Of enterprises practising business, those classified in Statistics Finland's Business Register under the industries to be examined are included in the calculation. The wages and salaries sum of enterprises serving a group is compiled into the group's industry. The most significant multi-industry enterprises have been divided into so-called kind-of-activity units to improve purity by industry. Business register is used for NACE information. Incomes Register contains comprehensive information on individuals' wages. The frame is updated monthly and demographic changes, such as start-ups and the most important mergers and split offs, are included instantly. Closures are included as soon as they are noticed, at the latest in four months delay. |
|||
3.7. Reference area | |||
Geographical area covered: the whole country. The Autonomous Region of Åland belongs in the statistical phenomenon described. Activities outside the geographical area are not included. |
|||
3.8. Coverage - Time | |||
Data is available from 1995. Some of the series published only nationally are produced only from 2010 onwards. |
|||
3.9. Base period | |||
Base (reference) year: 2021 |
|
|||
The data are provided as indices. |
|
|||
The reference period of wage and salary indices is month. |
|
|||
6.1. Institutional Mandate - legal acts and other agreements | |||
The production of the indices is based on the Statistics Act (280/2004), Regulation of the European Parliament and of the Council on European business statistics (EU) 2019/2152 and Commission Implementing Regulation (EU) 2020/1197. The Statistics Act (280/04) is the general act for the National Statistical Service (NSS). It contains the principles for the data collection, processing, and dissemination of official statistics. The act defines the roles of statistical authorities (Statistics Finland, Customs, National Institute for Health and Welfare, and Tike, Information Centre of the Ministry of Agriculture and Forestry) and other authorities producing statistics. The Statistics Finland Act (48/1992) states that Statistics Finland (SF) shall provide for the general development of official statistics in collaboration with other central government authorities. The Statistics Act requires that the primarily exploited sources for statistical purposes shall be the data accumulated in the administration of general government and the data produced as a consequence of the normal activities of employers, self-employed persons, corporations, and foundations. SF has the right to have access to these data under the Statistics Act. In addition, all public and private entities in Finland are obliged to provide SF with data on their finances, products and staff as necessary for the production of statistics. The right of SF to collect data by virtue of the obligation does not extend, however, to data that are kept confidential for reasons of international relationships, public safety, the interest of national defence, or the safety of the state. Before any data collection based on the obligation, the statistical authority must consult the respondents or their representatives about the contents, timing, collection methods, duration of storing of the data as well as about costs. Besides those data obtained directly from administrative sources data from natural persons are always collected on voluntary basis by using interviewing or mail and web surveys. In addition, the interviewees must be informed in advance in a written form. |
|||
6.2. Institutional Mandate - data sharing | |||
According to the Statistics Act, data obtained by four statistical authorities may be released to other parties either if permitted by legal provisions explicitly concerning the NSS, or upon express consent of the subject of the data. As far as statistical authorities are concerned they are allowed to transmit confidential data with identifiers to each other if it is deemed necessary for the production of statistics. The same applies to the European Statistical System authorities (ESS Authorities). Co-ordination among data-producing agencies is normal practice at both specialist and top level. |
|
|||
7.1. Confidentiality - policy | |||
Several legal acts guarantee that individual data should be kept confidential. |
|||

Users are usually also invited to participate in discussions concerning the establishment of new statistics or revisions of existing ones. |
|||
12.3. Completeness | |||
All the required series are produced and STS requirements fulfilled. |
|
|||
13.1. Accuracy - overall | |||
Accuracy is good due to total data in use. Due to supplementations the data updates for over twelve months. However the most notable changes affect the five most recent moths. |
|||
13.2. Sampling error | |||
Not applicable because census-like data is used. |
|||

The first publication is 35 days after the end of the reference month. |
|||
14.2. Punctuality | |||
Usually data is delivered on time but exceptionally data delivery (M3/2019) was late because the administrative source was not accessible as normal (https://stat.fi/en/statistics/documentation/ktps#Accuracy,%20reliability%20and%20timeliness). |
|
|||
15.1. Comparability - geographical | |||
European definitions are used and therefore the results are internationally comparable. The whole national territory is equally covered. |
|||
15.2. Comparability - over time | |||
Comparable data is available from 1995. Some of the series published only nationally are produced only from 2010 onwards. |
|||
15.3. Coherence - cross domain | |||
Comparisons are made quarterly to number of employed persons of the Labour Force Survey and to the Index of wage and salary earnings. Comparisons are also made with the annual data from the Business Register on less frequent basis.
Sources of differences between statistics are as follows:
Separate purposes of use of statistics
Calendar year vs. the accounting period
Comparability of concepts
Comparability of the population |
|||
15.4. Coherence - internal | |||
The non-seasonally adjusted aggregates are always consistent with their sub-aggregates. |
|
|||
Total costs of survey data productions: 570¹ person-hours. Total burden on respondents: 20¹ person-hours. ¹on year 2009 |
|
|||
17.1. Data revision - policy | |||
Indices are revised according to changes in the data and errors are corrected. More detailed explanation can be found here https://www.stat.fi/org/principles/publication-principles-for-statistics/practices-when-changes-are-made-to-statistical-data. |
|||
17.2. Data revision - practice | |||
Because the Incomes Register data supplements also after the due date, the data is repeatedly updated for over a year. Revised figures are published monthly according to the changes in data, but not announced as such. Methodological changes, errors in the newest release and the outstandingly significant revisions are announced at the time of change. Errors are corrected immediately. An annual overhaul of seasonal adjustment models is carried out. Monthly follow-up of revisions. Available for public in the latest publication https://stat.fi/en/statistics/ktps#pastPublications. No benchmarking. |
|
|||
18.1. Source data | |||
Administrative source (Incomes Register, which is basically a census) complemented by a statistical survey of the few of the largest multi-industrial enterprises in each industry (cut-off sample). Imputation is used for part of the missing data. The unit non response is corrected with one of the five simple rules, and imputed values are included into calculations only when the imputation can be considered as reliable. |
|||
18.2. Frequency of data collection | |||
Monthly, collected data refer to full reference month. |
|||

18.6. Adjustment | |||
Gross, working day adjusted, seasonally adjusted and trend series are produced with TRAMO/SEATS-method. The seasonal adjustment is performed on partially overlapping sub-periods, where structural breaks in seasonality patterns are detected. The overlapping period is set to twelve months in order to avoid breaks in the final seasonally adjusted series. - Starting from the January 2015 data, a new software J-Demetra+ is used. Information about the seasonal adjustment policies in Statistics Finland is available here: https://www.stat.fi/en/statistics/documentation/ktps#Methods The seasonal adjustment is performed on partially overlapping sub-periods, where structural breaks in seasonality patterns are detected. The overlapping period is set to twelve months in order to avoid breaks in the final seasonally adjusted series. |
