Rydym yn defnyddio mynegeion prisiau, megis y Mynegai Prisiau Defnyddwyr (CPI) i asesu chwyddiant - mesuriad o'r gyfradd cynnydd mewn prisiau ar gyfer nwyddau a gwasanaethau. Un modd o ddeall y CPI yw meddwl am fasged siopa fawr sy'n cynnwys detholiad o'r nwyddau a'r gwasanaethau a brynir gan aelwydydd. Mae'r CPI yn amcangyfrif newidiadau i gyfanswm cost y fasged hon.
The Consumer Prices Index including owner occupiers’ housing costs (CPIH) 12-month inflation rate was 1.5% in October 2019, down from 1.7% in September 2019.
The largest downward contribution to change in the CPIH 12-month inflation rate, between September and October 2019, came from electricity, gas and other fuels as a result of changes to the energy price cap.
Further downward contributions from “furniture, household equipment and maintenance” and “recreation and culture” were partially offset by rises in clothing and footwear prices.
Price quote data and item indices that underpin consumer price inflation statistics are now published, giving users unprecedented access to the detailed data that is used in the construction of the UK's inflation figures. With effect from January 2017 Consumer price inflation publication, these data are published on a monthly basis showing the latest month.
