The Consumers Price Index (CPI) is an indicator or measure of prices changes. It is a fixed weighted average of price relatives and is computed using the Laspeyres price index formula. The current weighting pattern is based on the 2005 Household Expenditure Survey (HES), which was carried out in 2005/06. The HES information was used to select the 'basket', which is the commonly used term for the goods and services prices for the purpose of compiling the CPI.
