The request has been made in a letter from RSS President Peter Diggle to the National Statistician John Pullinger.
The Johnson Review, which was published in January, recommended that the CPIH (the Consumer Prices Index which also takes into account of housing costs) be made the main measure of the UK’s inflation. The RSS disagrees with this course of action.
'We believe the review should have started from first principles by examining the different needs that consumer price indices aim to meet, then deciding what sort of index is required for each need and the extent to which they can, or cannot, be combined,' Professor Diggle wrote in the letter.
'We therefore urge that the approach of a full "household inflation index" based on actual expenditures incurred be examined in detail and a practical route for its development set out. I hope you will ask ONS staff to work on this so that it can be one of the options in the consultation.'
A UK Statistics Authority consultation on consumer price indices is expected in summer.
