Figure 1.1: Contributions to the annual rate of CPI inflation, % and percentage points
Source: ONS Calculations
Stacked bars reflect the percentage point contributions of each of the 85 class-level items in the Classification of Individual Consumption by Purpose (COICOP) to the annual percentage change in the Consumer Prices Index (CPI). The contribution of each class-level item is estimated separately, before being aggregated to the categories above. Note that a reduction in the contribution of a series to the annual rate of change need not imply falling prices, but could also reflect a lower rate of increase.
Food, drink & tobacco is composed of food, non-alcoholic and alcoholic beverages and tobacco. Housing is composed of actual rents and products and services for the repair of dwellings. Elect., gas & fuel includes electricity, gas and other household fuels as well as fuels and lubricants for motor vehicles. Transport & package holidays includes passenger transport by road, rail, air and sea, as well as package holidays. Education reflects the division-level contribution. The ‘other’ category reflects the combined contributions of the remaining 56 class-level items and a small rounding error, bringing the sum of contributions to the CPI (ONS 2014a).
