"The CPB World Trade Monitor (WTM) is an instrument for bringing together, aggregating, and summarizing worldwide monthly data on international trade and industrial production. Its purpose is to report monthly developments in trade and production at the earliest possible date, covering a sample of countries as large as possible. Country coverage is sufficient to identify monthly movements at the global level as well as at that of major economic regions. In the WTM, "trade" is trade in commodities (elsewhere referred to as "merchandise trade"). "Production" is industrial production, that is: value added in mining, manufacturing, and utilities (elsewhere referred to as "industry excluding construction")."
