Economic data

National consumer price index (not the HICP), all items, change from the same month a year earlier, in the COICOP 1999 classification. It is a separate identity from OECD.CPI.COICOP2018.ALL.YOY.M and is not spliced into it. 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. OECD Data Terms section 3 permits commercial reuse with attribution except separately restricted or third-party-owned data; no additional restriction was identified in the pinned flow metadata reviewed 2026-10-13. Collection time is not an original publication timestamp. Source observation flags and reference periods are retained.
