National CPI in the separate COICOP 2018 classification. It is not spliced into a COICOP 1999 identity. Countries still reporting COICOP 1999 remain in the original pack; USA is not represented in this 2018 cohort. Goods/services and housing scopes follow the publisher's national classification. 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 2026-10-11. Collection time is not an original publication timestamp. Source observation flags and reference periods are retained.
