Innéacs den sórt sin, is éard atá ann innéacs praghsanna lena dtomhaistear an meánathrú ar phraghsanna ón bpraghas sa bhonntréimhse go dtí an praghas sa thréimhse níos déanaí, agus úsáid á baint as na scaireanna luacha (ualuithe) ón mbonntréimhse.
Such an index is a price index that measures the average change in prices from the price for the base period to the price for a later period, using the value shares (weights) from the base period.
Meánathrú ar chaiteachas fuinnimh mar chéatadán (%) den chaiteachas iomlán in aghaidh deicile ioncaim (D) i ngeall ar athruithe ar phraghsanna breathnaithe (Lúnasa 2021 — Eanáir 2023 i gcoibhneas leis na 18 mí roimhe sin), gan tacaíocht bheartais agus freagairtí iompraíochta a áireamh.
Mean change of energy expenditure as a percentage (%) of total expenditure per income decile (D) due to observed price changes (August 2021 – January 2023 relative to the 18 months prior), excl. policy support and behavioural responses.
Thug an Coimisiún dá aire freisin i ndáil leis an méid sin go raibh an meánathrú ualaithe, tuairim is [0–3 %], nuair a chuir sé meáchan ainmniúil (teoiriciúil) CML i gcomparáid leis an meáchan CML a tuairiscíodh, i gcás an mhargaidh intíre.
The Commission also noted in this respect that when it compared the nominal (theoretical) CML weight with the reported CML weight, in case of the domestic market, the weighted average variance was at a minimum, around [0-3 %].
