Figure 27: Contributions to the difference in 12-month growth: CPIH-consistent non-retired households less CPIH-consistent retired households
UK, January 2006 to June 2017

Stacked bars reflect the percentage point contributions of each of the 87 class-level items to the difference in 12-month growth rates. The contribution of each of the 87 class-level items is estimated separately, before being aggregated to 7 distinct categories.
“Food & Drink” is composed of food, non-alcoholic and alcoholic beverages and tobacco. “Housing (exc. OOH)” is composed of actual rents and products and services for the repair of dwellings. Owner occupiers’ housing costs is a separate category, measured using the rental equivalence approach. “Elect., gas and fuel” is composed of electricity, gas and other household fuels as well as fuels and lubricants for motor vehicles. “Transport and 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 class-level items, bringing the sum of contributions to the inflation rate.
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 than the previous year.
