State Export Data
Although a State's actual agricultural export value cannot be measured directly, ERS maintains estimates of State shares of U.S. exports for total and selected individual commodities based on U.S. farm cash-receipts data. The estimates are for calendar years, with annual estimates available for 2000-2011. ERS has discontinued updates of an alternative fiscal-year (October to September) series of State export estimates based on State and commodity shares of production, but continues to provide the historical estimates based on that methodology.
