Quality report
Data description (SIMS 3.1)
The index of real estate maintenance costs describes the average development of the prices of real estate maintenance in different cost items of real estate management. The data are collected from different data sources and published quarterly.
Sector coverage (SIMS 3.3)
The index of real estate maintenance costs covers descriptions of the cost development of the maintenance of real estate located in Finland.
Statistical unit (SIMS 3.5)
The data of Statistics Finland's other indices are used in the index of real estate maintenance costs. These include the Consumer Price Index, producer price indices for services, Building Cost Index, Labour Cost Index and volume index of newbuilding.
Statistical population (SIMS 3.6)
Reference area (SIMS 3.7)
The statistics do not have a regional classification but the data concern the development of the maintenance costs of real estate in the whole country.
Time coverage (SIMS 3.8)
Data on the cost index of maintenance of real estate by type of building have been published quarterly and annually starting from 2000. Data by cost item and function type have been produced since 2010.
Base period (SIMS 3.9)
The base year of the time of real estate maintenance costs is 2015 (2015=100).
Unit of measure (SIMS 4)
The data of the index of real estate maintenance costs are published as index point figures. Change percentages are also calculated based on the indices on the quarterly and annual level.
Reference period (SIMS 5)
The reference period of the index of real estate maintenance costs is one quarter. The statistics are released six months from the end of the statistical reference year.
Classifications (SIMS 3.2)
The maintenance costs of real estate consist of management and maintenance costs. Real estate management costs refer to activities that maintain the conditions required for a real estate to remain operational with the help of activity monitoring and control, as well as service. Maintenance refers to regular actions that through repairs and renewals aim at maintaining a real estate and its equipment in a condition that at most corresponds with the original condition.
In the index of real estate maintenance costs, cost development is examined from two viewpoints, by cost item and by type of building in maintenance of real estate.
Concepts and definitions (SIMS 3.4)
Capital cost
Capital costs refer to the costs of capital tied to real estate, comprising interests and calculated depreciations. The interest is comprised of the return requirement set on tied capital. Capital costs include costs relating to the purchase and ownership of real estate, and costs relating to encumbrances or statutory obligations.
Consumable
When a piece of real estate is used, materials and supplies are consumed, such as water and electricity, and these are referred to as consumables.
Index real estate
An index estate is a real estate included in the index from whose weighted averages an overall index is calculated. The types of index real estates in the index of real estate maintenance costs are residential block of flats, commercial building, office building, health centre, school building and industrial building. A separate index of real estate maintenance costs is calculated for single-family houses.
Maintenance cost
Maintenance costs include expenditure arising from the management and maintenance of real estate, such as all its service, electricity, heating, water consumption and waste management costs.
Real estate
A real estate is a unit of ownership in a land or water area entered as real estate in the real estate register. Buildings and fixtures owned by the owner of a real estate and located on it belong to the real estate.
Real estate maintenance
Real estate maintenance refers to activity aimed at the preservation of the condition, value and properties of a real estate (Glossary of real estate activity).
Subcontracting
In the index of real estate maintenance costs, subcontracting refers to maintenance services purchased from a third party.
Institutional mandate (SIMS 6)

The index of real estate maintenance costs is produced from the data of different indices. There are no data agreements directly concerning the index.
Source data (SIMS 18.1)
The data of Statistics Finland's other indices are used in the index of real estate maintenance costs. These include the Consumer Price Index, producer price indices for services, Building Cost Index, Labour Cost Index and volume index of newbuilding.
Frequency of data collection (SIMS 18.2)
The data for the statistics on the index of real estate maintenance costs are collected monthly.
Data collection (SIMS 18.3)
The data of Statistics Finland's other indices are used in the index of real estate maintenance costs. These include the Consumer Price Index, producer price indices for services, Building Cost Index, Labour Cost Index and volume index of newbuilding.
Data validation (SIMS 18.4)
The data of the statistics are validated in the processing process by comparing the change with the data of the comparison period. Observations exceeding the threshold value are checked in a separate processing.
Data compilation (SIMS 18.5)
The data of different sub-indices are gathered together in the compilation process and the index point figure is calculated.
Overall accuracy (SIMS 13.1)
The change calculations of the cost level of the index of real estate maintenance costs assume that no major changes will occur in the consumption of the input headings. For example, the index does not take into account the change in heating needs caused by changes in weather conditions between different periods.
Quality assurance (SIMS 11.1)
Quality management requires comprehensive guidance of activities. The European Statistics Code of Practice forms the basis for the common quality system of the European Statistical System.
The Code of Practice is based on 16 principles that concern statistical authorities' independence, accountability and the quality of the processes and data to be published.
The principles are in line with the Fundamental Principles of Official Statistics approved by the United Nations Statistics Commission and are supplementary to them. The quality criteria of Official Statistics of Finland are compatible with the European Statistics Code of Practice.

Quality assessment (SIMS 11.2)
The quality of the statistics on the index of real estate maintenance costs is evaluated at different stages of the statistical process.
The index of real estate maintenance costs can also be used for long-term comparisons, when account is taken of the above-described changes in the input structure and volume over time. The average cost development indicated by the index of real estate maintenance costs can be examined relative to the data produced by other organisations operating in the real estate field.
The coverage of the renewed 2015=100 index differs from the indices of earlier base years in that it does not include real estate tax and plot rent.
Data revision - policy (SIMS 17.1)
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.
