Housing price statistics - house price index
- Data from second quarter of 2017 – extracted on 11 October 2017. Most recent data: Further Eurostat information, Main tables and Database. Next planned update: 18 January 2018.
This article describes the house price index (HPI) in the euro area and the European Union (EU), presenting data on this indicator both at European and Member State level. It also provides examples of possible use of this indicator in relation to other statistics, such as consumer price indices, rent price indices and household disposable income. Finally, a summary description of the methodology used in the compilation of the HPI is given.
The HPI shows the price changes of residential properties purchased by households (flats, detached houses, terraced houses, etc.), both newly-built and existing ones, independently of their final use and independently of their previous owners. The Member States’ HPIs are compiled by the national statistical institutes, while Eurostat calculates the euro area and EU HPIs.

Main statistical findings
The index levels (2015 = 100) for the euro area aggregate and EU aggregate house price indices are shown in Figure 1.
The annual growth rate of the euro area and EU HPIs is presented in Figure 2. Looking at the entire period, the annual growth rate of the EU HPI reached a maximum of 10.2% in the fourth quarter of 2006, and a minimum in the second quarter of 2009, with -6.0%.
Table 1 presents the quarter on quarter and the annual growth rates for the HPI for the most recent four quarters.
HPIs are computed as Laspeyres-type annual chain indices allowing weights to be changed each year. The European Union HPIs are calculated as weighted averages of the national HPIs, currently using as weights the GDP at market prices (based on PPS) of the countries concerned. The weights used in 2017 are based on data for the preceding year (2016). These weights are illustrated in Figure 3 for the euro area.
Sub-indices for new and existing dwellings
As of December 2014, in addition to the price index for total dwellings transacted in the market, Eurostat publishes separate indices for newly built and existing dwellings (prc_hpi_a). The separation of dwellings into newly built and existing is relevant due to their often different price evolutions. Due to limited data availability, no European aggregates are compiled for these sub-categories.
The weights of the indices for new and existing dwellings are disseminated as parts per thousand of the expenditure (with total dwellings = new dwellings + existing dwellings = 1 000) (prc_hpi_q). The weights for the 2017 indices are illustrated in Figure 4 for available countries.
Dynamics in the housing market: uses of the house price index and policy implications
The HPIs has been used in conjunction with other macroeconomic statistics to build derived indicators for the analysis of the housing market dynamics.
A well-known example is the deflated (or real) house price index, which is part of the Scoreboard of indicators used in the Macroeconomic Imbalances Procedure (MIP) of the European Commission.
The deflated HPI is the ratio between the nominal HPI and an index of consumer price inflation. A consumer price index, such as the HICP, or a national accounts final consumption deflator can be used for stripping out consumer prices inflation from the HPI. The deflated HPI included in the MIP Scoreboard uses the national accounts final consumption deflator. The deflated HPI growth rate is a key variable for the analysis of house price cycles. In particular, a too high growth rate is considered an early warning indicator of tensions in the real estate market signalling the risk of price bubbles. The alarm threshold adopted in the context of the MIP is 6 % of annual growth rate in the deflated HPI. The level of the threshold was established by DG ECFIN in cooperation with central banks. It was set on the basis of an analysis of historical data on past boom and bust cycles of house prices.
The deflated HPI for the euro area and the EU is presented in Figures 5 (quarterly index) and 6 (annual rate of change). The European aggregates mask significant differences between Member States, as it can be seen in Table 2 - annual deflated HPI. Figure 7 illustrates well the magnitude of the differences among available countries in the annual rate of change, for the year 2016.
In order to put house price dynamics into perspective, analysts have developed other indicators that combine the HPI with, for example, the price index of rents, in the form of a price on earnings ratio, or measure affordability using price-to-per capita disposable income of households. Quarterly price to rent index ratios are shown in Figure 8 for the euro area and the EU, using Eurostat data for the HPI and Eurostat HICP for the category actual rents.
Handbook on Residential Property Prices Indices (RPPIs)
The financial and economic crisis has highlighted the importance of correctly measuring the prices of real estate properties. For most citizens, buying a residential property (dwelling) is the most important transaction during their lifetime. The House Price Indices (also named Residential Property Prices Indices - RPPIs) are index numbers measuring the rate at which the prices of residential properties are changing over time. Despite the importance of having official, comparable statistics on RPPIs, a common methodological framework at international level (similar, for example to the SNA for National Accounts or the ILO CPI manual for Consumer Price Statistics) was missing for residential property prices.
Given its position at the forefront of statistical developments in residential property prices since the early 2000's, in 2009 Eurostat launched an ambitious project to develop an International Handbook on RPPIs. The Handbook, released on 3 April 2013 electronically on Eurostat website, provides, for the first time, comprehensive guidelines for the compilation of RPPIs and explains in depth the methods and best practices used to calculate a RPPI. The Handbook primarily addresses official statisticians in charge of producing residential property price indices; at the same time, it addresses the overall requirement on RPPIs by providing a harmonised methodological and practical framework to all parties interested in the compilation of such indices.
The development of the RPPIs Handbook benefitted from the collaboration of Eurostat with the members of the Inter-Secretariat Working Group on Price Statistics, currently chaired by Eurostat: International Labour Organization (ILO), International Monetary Fund (IMF), Organisation for Economic Co-operation and Development (OECD), United Nations Economic Commission for Europe (UNECE) and the World Bank.
The Handbook is available on the dedicated Housing statistics webpage.
Data sources and availability
Methodological background information is given in the Handbook on Residential Property Prices Indices (RPPIs) .
The first and most important issue in the compilation of HPIs is the availability of data on dwelling purchases. This refers to information about the price of the transaction and the dwelling characteristics. The dwelling characteristics which most influence price are the type of dwelling (flat, detached house, terraced house, etc.), its size and location. A second issue is the heterogeneity of the housing market, where virtually every dwelling bought and sold is different from the others in some respect. The consequent quality adjustment from one time period to the next is also a major methodological issue in compiling house price indices. The HPI should be seen as an independent price index aimed at measuring price developments for dwellings transacted in the market. The main technical characteristics of the HPI are:
- the price of land is included in the price and in the weight (gross acquisition concept);
- only actual transactions of dwellings are covered;
- market prices for residential properties are covered, while non-market prices are ruled out of the scope of the HPI; meaning that self-built dwellings are excluded, with the possible exception of turnkey pre-fabricated houses;
- the focus is on the measurement of price developments for all residential properties purchased by households, independently of their final use; so dwellings bought by households for uses other than owner-occupancy are included, for example for investment;
- all purchases of new and existing dwellings are to be considered, independently of their previous owner; so existing dwellings transacted between households are included.
Prices cover the acquisition cost of a property in itself, and not the total cost that is necessary to acquire, own and maintain a residential property; so other costs related to the acquisition of the property and major repairs are ruled out from its scope.

In recent years, the analysis of housing markets has intensified as has the demand for high quality statistics on national, euro area and EU housing, in particular on residential property price indices. Eurostat and the national statistical institutes have been working together since 2002 on a series of pilot projects to set up a system to provide harmonised data for residential property prices at European level. Prior to this work, there was very little comparability between national data on housing prices within the EU. The development of comparable, timely and frequent statistics on changes in residential property prices has been considered an essential target for European statistics.
In this context, the terms 'residential property price', 'house price' and 'dwelling price' are used interchangeably to describe the price developments of all residential properties purchased by households (flats, detached houses, terraced houses, etc.), both new and existing, independent of their final use and independent of their previous owners. The emphasis is on market prices, with non-market prices being ruled out from the scope of the house price indices (self-build dwellings are therefore excluded. The price of dwellings follows a gross acquisition concept, i.e. it includes the land price component.
