It should be noted that Production, Supply, and Distribution (PSD) data in GAIN reports are NOT official USDA data, but represent estimates made by FAS Attachés. Official USDA PSD data are determined after analyzing all overseas reports and drawing on additional sources, including more than 1,500 documents received from private and public sources around the world, global weather information, and satellite imagery analysis. After this analysis, official USDA data are released in USDA’s "World Agricultural Supply and Demand Estimates" monthly report and in FAS’ "World Production, Market, and Trade" reports.
