Mynegeion chwyddiant a phrisiau

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.
