CPIH-consistent inflation rate estimates for UK household groups (plutocratic weighting)
19 November 2019
An error has been identified in the quarter 1 2019 data for CPIH-consistent inflation rate estimates for UK household groups.
This was caused by an issue with the 2017 to 2018 Living Costs and Food Survey (LCF) dataset, which is used to calculate expenditure estimates for different household groups. This is the same error which affected Retail Prices Index calculations in March and June 2019, and there was a further error with the imputed rent estimates attached to the LCF dataset. We have also taken this opportunity to make refinements to the modelled estimates.
Please be aware of this if using this data. We will correct this error as soon as possible. We apologise for any inconvenience. Please contact firstname.lastname@example.org for more information.
