Statistical information in the database is based primarily on data provided by countries through questionnaires or official publications
Accuracy and Completeness
The quality of these data varies depending on each country's ability to collect and compile such statistics. Data are verified for accuracy and completeness by all information at disposal, such as foreign trade, industry and commodity reports, and correspondence with countries when data are questionable.
Processing Method: Whenever national offices fail to report or do not report in time, estimates are provided by FAO. In the absence of other information, export data are used as production estimates and the returns of major trading partners are used as trade estimates. Data for non-reporting countries are also estimated using published national reports, industry association reports and other relevant material. Such estimates are appropriately flagged.
