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 8.8% in the 12 months to July 2022, up from 8.2% in June.
The largest upward contributions to the annual CPIH inflation rate in July 2022 came from housing and household services (principally from electricity, gas and other fuels, and owner occupiers' housing costs), transport (principally motor fuels), and food and non-alcoholic beverages.
On a monthly basis, CPIH rose by 0.6% in July 2022, compared with no change in July 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 is used in the construction of the UK's inflation figures.
