Reviewed series · Prices · Monthly · % y/y · OECD.CPI.COICOP1999.ALL.YOY.M

National consumer price index (not the HICP), all items, change from the same month a year earlier, in the COICOP 1999 classification.

Enrolled only for reviewed countries still reporting COICOP 1999 currently; the United Kingdom (the OECD series does not match ONS CPI) and India (does not match MoSPI's 2024-base CPI) are excluded.
