What this measures

The change in the national consumer price index for all items compared with the same month a year earlier, as compiled by the OECD from national sources. National CPIs follow national methods, so they can differ from the harmonised EU index. Countries that have moved to the 2018 classification of consumption (COICOP 2018) are taken from the OECD's COICOP 2018 table, the others from its earlier table; each country's series comes from one table only.
