CPI and RPI Index: Updating Weights

An important feature of the Consumer Prices Index and the Retail Prices Index is the weighting applied to the representative 'basket' of goods and services bought by consumers within the United Kingdom. This process involves weighting together price changes in the indices according to latest available information on household spending patterns, ensuring each category of goods and services takes its appropriate share. This article describes the annual updating process and a brief explanation of the main changes for 2011.
