The trade matrix is a detailed analytical dataset from the International Merchandise Trade Statistics (IMTS), maintained by the United Nations Statistics Division (UNSD). It includes officially reported trade data submitted by member countries, as well as estimates to cover data gaps. These estimates also account for adjustments made to under-reported trade figures, providing a more complete and accurate picture of global trade flows. The matrix features high-level aggregates, with the world serving as both the exporter and the importer, offering an overview of international trade patterns.

Further details on the full methodology for compiling and updating the trade matrix, including data collection, estimation procedures, and adjustment techniques, are provided below.
