Methodology
Percentage change in the national consumer price index, all items, on the same month of the previous year. Not seasonally adjusted. Countries that have moved to the COICOP 2018 classification are read from the OECD's COICOP 2018 table, the rest from its COICOP 1999 table. National statistics as compiled by the OECD. Read from the OECD's SDMX API, or from its DBnomics mirror when the OECD's API is unavailable; the series' source note says which. Some values are flagged by the source as a break in the series.
