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 1.7% in February 2020, down from 1.8% in January 2020.
The largest contribution to the CPIH 12-month inflation rate in February 2020 came from housing, water, electricity, gas and other fuels (0.52 percentage points), which fell by 0.03 percentage points from January.
The contributions to change in the CPIH 12-month inflation rate were relatively small compared with movements in most months.
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.
