Acadametrics House Price Index

Published: October 6 2004 17:34 | Last updated: January 8 2010 09:34

The Acadametrics House Price Index series has been updated with the most recent monthly data available from the Land Registry.

The Acadametrics House Price Index comprises the published Land Registry house price data, smoothed and seasonally and mix adjusted by Acadametrics, combined with an “Index of Indices” model in order to account for transactions not yet reported to the Land Registry. The Acadametrics House Price Index uniquely uses all of the Land Registry data including cash purchases. It is designed to provide the most factual record available of domestic property prices in England and Wales and a true guide to house price inflation. This index used to be called the FTHPI until the end of 2009.

The Acadametrics House Price Index is calculated on a seasonally and mix adjusted basis, as follows:

How the index is calculated

Figures for the most recent months are produced using the latest information from the Land Registry’s database of monthly property transactions and a statistical model to collate information from other published house price figures.

The Acadametrics index weights information from the Halifax, Nationwide and Office of the Deputy Prime Minister according to their past reliability in predicting Land Registry figures. The outcome from the modelling process is smoothed to avoid the erratic month to month fluctuations observed in some other indices.

The Acadametrics mix-adjusted index (AcadHPI MA) does allow for the relative changes in prices in the regions and among the four property types — detached, semi-detached, terraced and flats/maisonettes — that the Land Registry collects.
