Reference metadata

The HPI and OOHPI reference metadata gathers, under a standard structure, sources and summary information regarding data quality and the production process in general.

With a view to making European Statistics more accessible and clear, the National Statistical Institutes producing housing price statistics data are also documenting their national practices under the same structure.

Reference year 2015=100

Starting with the release of 1st quarter 2017 data on 19 July 2017, the HPI and OOHPI  index series are published with reference year 2015=100.

European Parliament and Council Regulation (EU) 2016/792, of 11 May 2016, provides the legal basis for updating the HPI/OOHPI reference year from 2010=100 to 2015=100.

Manuals / handbooks

Technical manual on Owner-Occupied Housing and House Price Indices - 2017

This technical manual provides guidelines for the development of a price index on Owner-Occupied Housing (OOH) under the net acquisition approach, as well as practical advice for the compilation of the house price index (HPI).

A significant element of OOH costs are those associated with the initial acquisition of the dwelling and by far the biggest element of the latter is the price of the property. Changes in the prices of dwellings are measured by the HPI, which is an important indicator in its own right.

Handbook on Residential Property Prices Indices (RPPIs) - 2013

This Handbook provides comprehensive guidelines agreed at international level for the compilation of RPPIs and explains in depth the methods and best practices used to calculate an RPPI. It also examines the underlying economic and statistical concepts and defines the principles guiding the methodological and practical choices for the compilation of the indices.

The RPPIs Handbook has been written by leading academics in index number theory and by recognised experts in RPPIs compilation. Its development has been co-ordinated by Eurostat, the statistical office of the European Union, and it has been jointly published with the 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.
