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.

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

Real estate sales data cover transactions in the Slovak republic covered by Cadastre office

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 Young 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).

Market prices of dwellings

The target population is a set of all dwelling transactions purchased in the Slovak Republic.

Data are available for the whole Slovak Republic.

Data are 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.

The HPI is a chain-linked Young price index that use the year 2015 as reference base year at Eurostat web page.

The Statistical Office of the Slovak Republic publishes HPI with the base year 2010.

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.

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

There are no agreements as regards data sharing in National statistical system.

The Statistical Office of the Slovak Republic (SOSR) is responsible for the protection of confidential data obtained and guarantees their use exclusively for statistical purposes. In accordance with the Act on State Statistics No. 540/2001 Coll. §2g and §30, the SOSR may not publish confidential statistical data, but only information resulting from the aggregation of confidential statistical data, which does not allow direct or indirect identification of the reporting unit.

Published indices are calculated from the aggregated individual data - no disclosure is then possible.

An advance release calendar that gives the precise release dates for the coming four months is disseminated on the Internet website of the Statistical Office of the Slovak Republic. The calendar is updated monthly. It covers main economic and social indicators established currently within the EU regulations and IMF special standard, which define timeliness standards as well. In the Release Calendar release dates defined by Eurostat are taken into consideration.     

Release calendar

The First Release Calendar contains timetable of the first release of selected indicators. Data are published in the given day at 9 o´clock on the Internet website of the SOSR (www.statistics.sk) in the part Products\Information reports Catalogue.

Quarterly for the HPI.

Eurostat informs on HPI development in the quarterly News release: Eurostat's database

Information report on HPI (dwellings price development) is published according to release calendar (about sixty days after the reference quarter) by SO SR. The reports are available in Information Reports Catalogue (key word: dwellings) and also in archive of information reports catalogue.

HPI_Eurostat-database

HPI-database of Statistical office of the Slovak Republic

Eurostat publishes HPI index numbers on the quarter basis. The data is in the on-line database.

SO SR also publishes HPI on the quarter basis in the on-line database.

Micro-data is not disseminated.

Not relevant.

The HPI methodology is described in quality report. The source data are available at the department of price statistics.

HPI quality report in Slovak language

The data are checked for completeness and consistency with HPI statistical concepts and definitions.

The quality report refers to information in HPI Inventory

The requirement to consult with users of statistical information is stipulated in the State Statistics Act itself. Consultations in the preparation of state statistical surveys are under way in the preparation of the State Statistical Surveys Program. In practice, users are consulted on a bilateral basis in order to obtain information on the requirements and expectations of users.

Not available.

All relevant expenditure categories defined in implementing regulation are covered.

The HPI was perceived to be accurate and to reflect well the overall behaviour of the housing market.

HPI are calculated on the basis of data provided by the Cadastral Office, covering transactions carried out in the Slovak Republic.

Not known

SO SR publishes HPI 60 days after the reference quarter.

Eurostat is provided with HPI in compliance within T+85 deadline.

HPI between regions are comparable.

Real estate price indices for Q1 2010 to Q1 2021 are calculated from the data of the National Association of Real Estate Agencies of Slovakia or from its software partner, from Q2 2021 they are calculated from data from the cadastre office.

The indices for purchase of dwellings are compared with indices compiled by National Bank of Slovakia – the differences can be explained to certain level by different way of compilation.

All figures are checked for internal consistency.

SO SR does not measure the burden of reporting units because obtains the data from Cadastre office as administrative data source.

The HPIs data is not subjected to periodic and systematic revisions. The HPI data may be revised

In the year 2012 the HPI  time series for the period 1st Q 2010 - 2nd Q 2012 were revised.

See below.

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. 

The source of the weights are the data from cadastre office  - weights are derived from the value of individual dwelling prices.

SO SR does not calculate House sales indicators.

Data are collected and published quarterly.

SO SR is provided with the dwelling prices from Cadastre office.

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.

See below.

See below.

HPI is a Young price index. So SR uses weights from t-1 (not price updated) to aggregate price indices with Q4(t-1)=100.

Average prices at the district level are calculated, then indices are calculated against the 4th quarter of the previous year. The indices are then aggregated using the Young formula (weights from t-1 (not price updated) are used to aggregate price indices with Q4(t-1)=100).

The weights figures are annually updated on the basis of value of covered transactions from the previous year, provided by current data source.

Elementary aggregate weights are not adjusted with an appropriate price change between the year t-1 and the fourth quarter of the year t-1.

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

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.

SO SR does not use hedonic methods.

SO SR does not use SPAR methods.

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.

See below.

Transfer of ownership.

VAT is included in the price of new dwellings.

Taxes other than VAT are not included in the price of dwellings.

In the Slovak Republic, state subsidies are provided only as support for mortgage repayments for young people and they do not affect the prices.

The price of land is included in both prices and weights.

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.

Non-market transactions are not covered.

Multi-object transactions are not covered in the calculation of HPI.

Fractional transactions (when only a share of a dwelling ownership is sold) are covered by Cadastre data but as outliers are excluded form the calculation.

The price per square meter within a district is calculated for all transactions 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.

Not relevant

No adjustments other than quality adjustment methods are applied to the HPI data.
