PSD

PSD (Production, Supply and Distribution) is a USDA database of country-level output, trade, consumption, and stocks for agricultural commodities, the data behind reports like WASDE.

The PSD database is the US Department of Agriculture’s ongoing record of production, supply, and distribution figures for agricultural commodities, covering the United States and other countries, going back many years. It is the underlying data source behind higher-profile releases like the monthly WASDE report.

Because it covers countries beyond the United States, PSD is a common reference for comparing crop production, consumption, and stocks across producing and consuming nations on a consistent basis, something not every national statistics agency makes easy to do otherwise. Analysts and researchers use PSD directly when they need a longer history or more country detail than the summary tables in WASDE provide, though both draw from the same underlying USDA estimates and analyst judgment.
