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.

3.1. Data description
The House Price Index (HPI) is a quarterly indicator that measures the changes in the dwellings transaction prices that households acquire on the market. Prices include land value.
The data on the HPI is provided in the form of an overall index number comprising two sub-indexes: Purchases of newly built dwellings and Purchases of existing dwellings.
3.2. Classification system
Commission Implementing Regulation (EU) 2023/1470 of 17 July 2023 laying down the methodological and technical specifications in accordance with Regulation (EU) 2016/792 of the European Parliament and of the Council as regards the house price index and the owner-occupied housing price index, and amending Commission Regulation (EU) 2020/1148 defines the following expenditure categories within House price index (HPI):
H.1. Purchases of dwellings:
H.1.1. Purchases of newly built dwellings;
H.1.2. Purchases of existing dwellings.
3.3. Coverage - sector
Real estate sales data cover transactions in the Slovak republic covered by Cadastre office for which the size in square meters is available.
3.4. Statistical concepts and definitions
The HPI shall cover all transactions of dwellings regardless of its final use. This index thus covers not only the transactions that are new to the household sector but also all that are traded.
Index figures for the purchase of new and existing dwellings are compiled on the basis of full transaction prices, which are collected through Cadastre office. Transaction prices include the value of land.
The HPI is a chain-linked Laspeyres price index. HPI data are presented in the form of quarterly index numbers and quarterly rate of change and annual rate of change.
The HPI is weighted by the value of dwelling transactions (new and existing) for the previous year. Gross concept is applied; weights data include the value of land. Weights refer to the transactions carried out in the previous year (t-1) price updated to the 4thQ of the previous year.
3.5. Statistical unit
Market prices of dwellings.
3.6. Statistical population
The target population is a set of all dwelling transactions purchased in the Slovak Republic.
3.7. Reference area
Data are available for the whole Slovak Republic.
3.8. Coverage - Time
The HPI is available from the 1st quarter of 2006. Since 2009, the sample of districts covered has expanded. The data source has changed since the second quarter of 2021.
3.9. Base period
In order to achieve a chain-linked Laspeyres price index that use the year 2015 =100 as reference base year at Eurostat web page the HPI time series were recalculated using the price-updated weights from the year t-1 to 4thQ of the year t-1.
The Statistical Office of the Slovak Republic will publish HPI time series in order to achieve chain-linked Laspeyres price index using the price-updated weights to the 4thQ of the previous year with the base year 2010 = 100.
Index figures with reference year 2015 are available and published at Eurostat web site, as well as quarterly and annual growth rates in percentage. Weights are given in parts per 1000.
HPI are published with reference year 2010, as well as quarterly and annual growth rates in percentage at the website of Statistical Office of the Slovak Republic.
Reference period is quarter.

18.1. Source data
See below.
18.1.1. Prices
The index numbers for the purchase of newly built and existing flats and family houses are compiled on the basis of full transaction prices, which are collected by the Cadastral Office.
18.1.2. Weights
The source of the weights are the data from cadastre office - weights are derived from the value of individual dwelling prices.
18.1.3. Source data - House Sales indicators
SO SR does not calculate House sales indicators.
18.2. Frequency of data collection
Data are collected and published quarterly.
18.3. Data collection
SO SR is provided with the dwelling prices from Cadastre office.
18.4. Data validation
Data are checked for internal consistency. As regards compilation of index for Purchase of newly built dwellings and Purchase of existing dwellings SO SR is provided with the average prices for sales in the given quarter in breakdown by districts. SO SR adjusts data from extreme prices (outliers); in practice there are some cases where Statistical Office makes some adjustment.
18.5. Data compilation
See below.
18.5.1. Calculation and Aggregation
See below.
18.5.1.1. Index formulae
Now HPI is a Laspeyres price index. So SR uses weights from t-1 price updated to Q4(t-1).
18.5.1.2. Aggregation method
Average prices at the district level are calculated, then indices are calculated against the 4th quarter of the previous year. The indices are aggregated using the Laspeyres formula (weights from t-1 price updated to Q4(t-1).
18.5.1.3. Derivation of sub-index and elementary aggregate weights
The weights figures are annually updated on the basis of value of covered transactions from the previous year, provided by current data source.
18.5.1.4. Price updating
The elementary aggregate weights are price updated with an appropriate price change between the year t-1 and the fourth quarter of the year t-1.
18.5.1.5. Chaining and linking method
The indices are calculated to the 4th quarter of the previous year, then they are multiplied by the index for the 4th quarter of the previous year to the base period
18.5.1.6. Compilation of sub-indices
A stratification approach is used for the compilation of Index for Purchase of newly built dwellings as well as for Index for Purchase of existing dwellings.
18.5.1.6.1. Hedonic method
SO SR does not use hedonic methods.
18.5.1.6.2. SPAR method
SO SR does not use SPAR methods.
18.5.1.6.3. Stratification
Stratification is based on geographical area (defined at district level). Dwellings are categorized by type of a dwelling (flats, family houses). The prices per square meter are used in the compilation of HPI.
The two main strata are flats and family houses, they are further stratified to new and existing dwellings. The number of covered strata for flats are 40 districts for new flats and 59 districts for existing flats. Family houses are not stratified in district level.
18.5.2. Other processing issues
See below.
18.5.2.1. Timing for pricing
Transfer of ownership.
18.5.2.2. Treatment of VAT
VAT is included in the price of new dwellings.
18.5.2.3. Treatment of other taxes
Taxes other than VAT are not included in the price of dwellings.
18.5.2.4. Treatment of government subsidies
In the Slovak Republic, state subsidies are provided only as support for mortgage repayments for young people and they do not affect the 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. Housing cooperatives in the Slovak Republic cover about 2% of all real estate intended for housing. We cannot identify them from the source data. If the average price per square meter differs significantly from the average price for a given district, we will exclude it from calculation.
18.5.2.7. Treatment of non-market transactions
Non-market transactions are not covered.
18.5.2.8. Treatment of multi-object transactions
Multi-object transactions are not covered in the calculation of HPI.
18.5.2.9. Treatment of fractional transactions
Fractional transactions (when only a share of a dwelling ownership is sold) are covered by Cadastre data but as outliers are excluded from the calculation.
18.5.2.10. Outliers detection
The price per square meter within a district is calculated for all transactions (for which the size in square meters is available) from the data on the total price and area of the property, outliers are determined by comparing the prices per square meter for transactions carried out within one district.
18.5.2.11. Treatment of incomplete data source coverage
Not relevant
18.6. Adjustment
No adjustments other than quality adjustment methods are applied to the HPI data.
None.
