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) rose by 9.6% in the 12 months to October 2022, up from 8.8% in September 2022.
The largest upward contributions to the annual CPIH inflation rate in October 2022 came from housing and household services (principally from electricity, gas, and other fuels), food and non-alcoholic beverages, and transport (principally motor fuels).
On a monthly basis, CPIH rose by 1.6% in October 2022, compared with a rise of 0.9% in October 2021.
Price quote data and item indices that underpin consumer price inflation statistics are now published, giving users unprecedented access to the detailed data that are used in the construction of the UK's inflation figures. With effect from the January 2017 consumer price inflation publication, these data are published on a monthly basis showing the latest month.
