Figure 5: “Core inflation" (%) and contributions from broad expenditure categories
Source: Office for National Statistics
"Core inflation" comprises all items in the CPI, less energy, food, drink and tobacco
Stacked bars reflect the percentage point contributions of selected class-level items in the Classification of Individual Consumption by Purpose (COICOP) to the annual percentage change in the core 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 series to the annual rate of change need not imply falling prices, but could also reflect a lower rate of increase.
Housing is composed of actual rents and products and services for the repair of dwellings. Catering services includes restaurants and cafes, and canteens. Education reflects the division-level contribution. Transport & package holidays include passenger transport by road, rail, air and sea, as well as package holidays. Recreation & Culture reflects the division-level contribution, excluding package holidays. The ‘other’ category reflects the combined contributions of the remaining class-level items and a small rounding error, bringing the sum of contributions to the Core CPI. See the Guidance & Methodology pages of the ONS website for more details on the goods and services included in CPI.
