Sector coverage
The strata are based on the size and industrial classification of the enterprise. Large enterprises are grouped as a separate stratum. Small enterprises with fewer than five employees are not included in the statistics. Many small construction enterprises specialise in renovation building, such as installation and finishing work.
In 2021, most (86%) of the construction enterprises were small businesses with fewer than five employees. However, the turnover of construction enterprises with fewer than five employees only accounts for 17 per cent of the construction sector turnover.

Renovation
In Statistics Finland's different statistics, renovation is broken down to basic renovation and refurbishment. The term used for refurbishment varies in different statistics. In the Household Budget Survey, for instance, it is referred to as maintenance repairs.
In national accounts, building renovation is included in fixed capital formation and refers to fundamental improvement of a building. After renovation the value of a building is comparable to new.
Refurbishment is a less significant activity than renovation. Refurbishment refers to regular repairs and maintenance to buildings or parts thereof (also referred to annual repairs).
Building extensions count as newbbuilding.

Source data and data collections
Source data
1. Annual statistics on renovation building
From the 2012 statistical year onwards, the statistics have been based on a sample-based inquiry sent to construction enterprises with at least five employees. The sample comprises all enterprises with at least 60 employees (the minimum was raised from 50 to 60 in the 2019 statistical year) and enterprises with a turnover of more than EUR 40 million or a balance sheet of more than EUR 300 million. Enterprises under the threshold but employing at least five persons have been selected for the sample based on random sampling.
The sampling frame of the statistics is based on Statistics Finland’s Register of Enterprises and Establishments. The inquiry is carried out together with the financial statements inquiry for enterprises and its financial statements database is used to analyse enterprises’ background data. The financial statements statistics also contain figures taken from the business tax data of the Finnish Tax Administration.
2. Data on self-assessed taxes collected by the Finnish Tax Administration
The index is calculated using data on self-assessed taxes derived from the Tax Administration. The data contain the value added tax data of the enterprises submitting the data on a monthly, quarterly and annual basis. Enterprises with an annual turnover of more than EUR 100,000 must submit the data on a monthly basis. Enterprises with an annual turnover of between EUR 30,001 and EUR 100,000 must submit the data on a quarterly basis. Enterprises with a maximum annual turnover of EUR 30,000 must submit the data on an annual basis.
3. Reports on contract details submitted to the Finnish Tax Administration
Enterprises ordering construction work must submit the details of the contracts they have concluded to the Finnish Tax Administration. The report must be submitted if the enterprise orders any of the following construction work from another enterprise:
- Building construction and related preparatory, demolition and installation work or any other construction services referred to in the Value Added Tax Act.
- Erection and dismantling of scaffolding
- Leasing of employees for construction work.
The first report on contract details must be submitted when the construction work starts at the site. If advance payments are made for the work, the report must be submitted for the month during which the advance payments have been made.
Contract details must be submitted by the fifth day of the second month following the reporting month. For example, the details for July must be submitted by 5 September. The last report must be submitted for the month for which the last invoice for the work is paid.

Methods
Data compilation
Shares of renovation building and newbuilding are generated for the strata by using the annual data collected for the renovation building statistics.
Domestic turnover details for the construction enterprises included in the statistics are taken from the Finnish Tax Administration’s data on self-assessed taxes for each target month and the value data for the contracts concluded by the enterprises are taken from the reports on contract details. These data are multiplied by the stratum-specific shares of renovation building and newbuilding so that monthly value data for renovation building and newbuilding can be generated for the enterprises. The value data are compared with value data for the previous year that have accumulated over the same period as the value data for the target month. The data are used as a basis for the time series of point figures, in which the monthly average for 2021 is 100.
Contract details accumulate over many months and they also include correction and deletion notifications. When the data are processed, the latest report on contract details received is used and outdated reports are deleted. When the rates of change are calculated, the delay in the accumulation of contract details is taken into account by using comparison data that have accumulated over the same period as the data for the target month for which the calculations are made.

Legal acts and other agreements
The compilation of statistics is guided by the Statistics Act. The Statistics Act contains provisions on collection of data, processing of data and the obligation to provide data. Besides the Statistics Act, the Data Protection Act and the Act on the Openness of Government Activities are applied to processing of data when producing statistics.
Statistics Finland compiles statistics in line with the EU’s regulations applicable to statistics, which steer the statistical agencies of all EU Member States.

Confidentiality - policy
The data protection of data collected for statistical purposes is guaranteed in accordance with the requirements of the Statistics Act (280/2004), the Act on the Openness of Government Activities (621/1999), the EU's General Data Protection Regulation (EU) 2016/679 and the Data Protection Act (1050/2018). The data materials are protected at all stages of processing with the necessary physical and technical solutions. Statistics Finland has compiled detailed directions and instructions for confidential processing of the data. Employees have access only to the data essential for their duties. The premises where unit-level data are processed are not accessible to outsiders. Members of the personnel have signed a pledge of secrecy upon entering the service. Violation of data protection is punishable.

Release policy
Statistics Finland publishes new statistical data at 8 am on weekdays in its web service. The release times of statistics are given in advance in the release calendar available in the web service. The data are public after they have been updated in the web service.

Data sharing
Accessibility and clarity
Statistical data are published as database tables in the StatFin database. The database is the primary publishing site of data, and new data are updated first there. When releasing statistical data, existing database tables can be updated with new data or completely new database tables can be published.
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
Revisions – i.e. improvements in the accuracy of statistical data already published – are a normal feature of statistical production and result in improved quality of statistics. The principle is that statistical data are based on the best available data and information concerning the statistical phenomenon. On the other hand, the revisions are communicated as transparently as possible in advance. Advance communication ensures that the users can prepare for the data revisions.
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.
The data contained in the trend indicator of renovation building are revised in later releases. Accumulation of and corrections to the reports on contract details submitted to the Finnish Tax Administration and used as source data for several months after the target month is the main reason for the revisions.
Quality assessment
Quality assurance
Quality management requires comprehensive guidance of activities. The quality management framework of the field of statistics is the European Statistics Code of Practice (CoP). The quality criteria of Official Statistics of Finland are also compatible with the European Statistics Code of Practice.
