Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

14.2. Punctuality
House price index numbers are sent to Eurostat within 85 days after the end of the reference quarter and weights are sent before 15 June of the year following the year to which the weights relate.
15.1. Comparability - geographical
Fully comparable to other EU countries. Total HPIs are not published for regions.
15.2. Comparability - over time
The released data on HPI's are fully comparable starting from 2015. In 2017 the methodology for compiling the indices of existing detached houses was updated. The HPI was revised accordingly, and backdata was calculated to form a comparable time series. In 2020, the methodology of price index of new multi-unit dwellings was updated and HPI was revised starting from 2015. In 2022, the methodology of price index of existing multi-unit dwellings was updated and HPI was revised starting from 2015. In addition, self-build dwellings were excluded from the HPI as well as from House sales indicators in 2022.
Starting from 2023Q4, changes in average prices is used instead of quality standardization in the calculation of the HPI for new dwellings when needed. This is only done in regions with only a few transactions, but might have an impact on the HPI for new dwellings of the whole country.
For house sales indicators the data are comparable starting from 2020.
In 2025, the HPI and house sales indicators were revised starting from 2020 as the data provider changed delimitation rules of existing dwellings in single-family houses.
15.3. Coherence - cross domain
The HPI ja OOHPI sub-indices for new dwellings are the same.
15.4. Coherence - internal
All figures are checked for internal consistency.

17.1. Data revision - policy
HPI data are revisable. The first publication is preliminary and finalised on the time of the publication of the next quarter. The published HPI data may be revised for mistakes, new or improved information, and changes in the system of harmonised rules.
17.2. Data revision - practice
The price data used in the national publication of the existing multi-unit dwellings is revised over the year, so that the final data for the year are published in the release concerning the first quarter of the following year. Rest of the HPI subindices are not revised.
House Sales Indicators are revised for existing and newly built dwellings in housing companies.
18.1. Source data
See below.
18.1.1. Prices
Existing multi-unit dwellings: The data of the statistics on multi-unit dwelling prices are based on the price information gathered by the Finnish Tax Administration for asset transfer tax calculation purposes. Additionally, the Tax Administration’s Register of Real Estate Property and Statistics Finland’s data on the dwelling stock that are based on the Population Register Centre’s Register of Buildings and Dwellings are also used for the statistics.
New multi-unit dwellings: The data of the statistics on new multi-unit dwelling prices are based on the information Statistics Finland receives via a private price monitoring service about transactions in new dwellings made by the largest real estate agents and building contractors and from Statistics Finland own data collection. For house sales indicators, the data used for new multi-unit dwellings is by the Finnish Tax Administration. The time of transaction for new dwellings is the first binding contract in HPI and the change of ownership in house sales indicators as well as in HPI item weights.
Existing detached houses: The data on transaction prices are obtained from the real estate register of the National Land Survey of Finland. Additionally, the dwelling stock data from the Population Register Centre’s register of buildings and dwellings is also used.
18.1.2. Weights
The source data for existing and newly built dwellings in housing companies is Tax Authorities' data. For existing single-family houses the source data is provided by National Land Survey of Finland.
18.1.3. Source data - House Sales indicators
For existing and newly built dwellins the data is Tax Authorities' data on transfer tax. For existing single-family houses data is from National Land Survey of Finland.
18.2. Frequency of data collection
Monthly data transmissions from real estate agents, Tax administration and National Land Survey of Finland. In addition, quarterly data collection on new multi-unit dwellings by Statistics Finland to building contractors that do not report via private price monitoring service.
18.3. Data collection
See 18.1.
18.4. Data validation
Controls on the quality of the data: Validation is started when data arrives and is imported into database . The validation covers following checks: 1. Prices which are considered to be too big or too small (possible misspelling or contract within the family etc.) 2. Missing characteristics of dwelling is checked (number of rooms, surface areas, year of completion, postal code etc.) 3. Statistics (e.g. number of transactions observed).
18.5. Data compilation
See below.
18.5.1. Calculation and Aggregation
See below.
18.5.1.1. Index formulae
HPI is a Laspeyres-type price index.
18.5.1.2. Aggregation method
Sub-indices are aggregated to a total HPI according to Laspeyres formula. Finnish HPI consists of three sub-indices: existing single-family houses, existing dwellings in housing companies and new dwellings in housing companies. For existing single-family houses, the elementary aggregates are aggregated using Log-Laspeyres formula, for existing dwellings in housing companies with Törnqvist and these two sub-indices are aggregated to existing dwellings using Laspeyres. Price index for new dwellings is aggregated from elementary aggregates using Laspeyres formula.
18.5.1.3. Derivation of sub-index and elementary aggregate weights
Weights are updated annually.
18.5.1.4. Price updating
The weight reference period is t-1.
18.5.1.5. Chaining and linking method
The HPI is calculated as a price change between current quarter and previous year’s last quarter and then chained from previous year’s index to current index using this change.
18.5.1.6. Compilation of sub-indices
The sub-indices for existing and newly built dwellings are adjusted for quality changes using hedonic models.
18.5.1.6.1. Hedonic method
HPI is compiled from three sub-indices which are all based on hedonic repricing. The index methods differ slightly due to different data sources and characteristics etc. In all of these, the index has two different parts, price change unadjusted for quality and a quality adjustment factor. For the sub-index of existing single-family houses, the dependent variable is logarithmic price per square metre and the explanatory factors are the age of a house, the square of age, abutting a shoreline, floor area and in Greater Helsinki the distance to Helsinki and elsewhere in the country the distance to a big, medium size and small town. All explanatory variables are in a logarithmic form. The shadow prices are calculated based on five years’ data and are updated annually. The quality unadjusted price index is based on unweighted geometric mean. For the new and existing flats (dwellings in housing companies), the dependent variable is logarithmic price per square metre. For existing dwellings the explanatory variables are floor area and its square root, age of the building and its square root, driving time to the nearest local centre and its square root and whether the dwelling is located on rented or own plot. For new dwellings, the variables are dwelling's floor area, the location of the dwelling and owner of the building lot -dummy. Shadow prices are based on one year's data and are updated annually. The quality unadjusted price indices are based on weighted arithmetic mean.
18.5.1.6.2. SPAR method
SPAR method not in use.
18.5.1.6.3. Stratification
Stratification not in use.
18.5.2. Other processing issues
See below.
18.5.2.1. Timing for pricing
The price of a dwelling is the price in the sale contract (in existing dwellings and multi-unit dwellings). The price index for new single unit houses describes how much the price of building an average single-family house has developed.
For newly built dwellings, the timing for pricing is the first binding contract in House Price Index. For House Sales Indicators, the timing for pricing is when ownership is transferred. For newly built dwellings in housing companies, the ownership is transferred when the building has been completed and the price has been paid in full. As the apartment can be sold in any phase of construction, the difference between first binding contract and change of ownership can be up to two years for new dwellings in housing companies.
18.5.2.2. Treatment of VAT
VAT is included in the price of new dwellings.
18.5.2.3. Treatment of other taxes
Asset transfer tax is not included in the price of dwellings.
18.5.2.4. Treatment of government subsidies
The HPI includes only transactions at market prices.
18.5.2.5. Treatment of land
The price of land is included in both prices and weights.
18.5.2.6. Housing cooperatives
Housing cooperatives are covered in the HPI.
18.5.2.7. Treatment of non-market transactions
Transactions between family members are omitted when possible, as well as price regulated apartments. Transactions with unusually low or high price are omitted as well.
18.5.2.8. Treatment of multi-object transactions
Multi-object transactions are included, if each apartment has their own price.
18.5.2.9. Treatment of fractional transactions
Fractional transactions are not included in the HPI.
18.5.2.10. Outliers detection
There is automatic deduction rules for outliers.
18.5.2.11. Treatment of incomplete data source coverage
For newly build dwellings in House Sales Indicators, for the first release the number and value have been estimated by multiplying it with 1,1.
18.6. Adjustment
No adjustments other than quality adjustment are applied to the HPI data.
None.
HPIs give comparable measures for changes in the prices of dwellings. They are calculated according to a harmonised approach and a single set of definitions.
