Calculated by Statistics of the World, not published by OECD: the percentage change from the same month a year earlier in OECD's calendar and seasonally adjusted industrial production index (OECD.PRODUCTION.INDUSTRY.IX.M, 2015=100), using 100 × (I[t] / I[t−12] − 1). Both months come from the same OECD read, reference area and adjustment. National-methodology volume index; industrial production excludes construction, and coverage and national collection methods differ. A national statistics office's own headline rate can differ, for example where it publishes a calendar-adjusted or unadjusted rate. A month gets a rate only when the publisher released the index for that month and for the same month a year earlier, in the same reference area. Absent months stay absent; a year-earlier index of zero or below leaves the month without a rate. Union of the source flags on both input months, so a rate is provisional or estimated whenever either month is; no flag is invented for the calculation itself. 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. Collection time is not an original publication timestamp.
