Overview
Annual estimates of U.S. exports by State and commodity group based
on each State's share of U.S. agricultural production. State exports
are updated annually on June 30.
Data Files (*.xls format)
Features
U.S. Agricultural Trade Briefing Room contains
analyses of U.S. agricultural trade and electronic publications.
Foreign Agricultural Trade of the United
States (FATUS) provides U.S. agricultural exports and imports,
volume and value, by country and by commodity. Updated monthly or
annually.
State Fact Sheets
provide information on population, employment, income, farm characteristics,
and farm financial indicators for each State in the United States.
Methodology
Data on the value of U.S. agricultural exports by State of production are not part of the U.S. export information collected by the U.S. Customs and Border Protection. Consequently, the Economic Research Service (ERS) estimates State agricultural exports using the Customs District-level export data compiled by the U.S. Census Bureau and the State-level agricultural production data supplied by the National Agricultural Statistics Service (NASS). Using these approximations, a State that is the largest producer of an agricultural commodity will also account for the largest share of U.S. exports of that commodity. Countries of destination for each State's exports cannot be determined.
U.S. agricultural commodity exports often are produced in inland States. From the farm, a commodity is sold to a local elevator, which in turn may sell it to a larger elevator located at a major transportation hub, which then moves the commodity to a port. As the commodity passes through several States before being exported, the State-of-origin often is lost or the product commingled with similar product from other States. Frequently, the State from which the commodity began its export journey, not necessarily the State in which the commodity was produced, is reported by the exporter. To more accurately reflect the situation for inland agricultural producing States, ERS calculates U.S. State agricultural exports based on a State's share of production of the exported commodity.
The underlying crop and livestock production and slaughter estimates by State are publicly available from NASS on their Data and Statistics page. The State's share of production of the commodity is simply applied to the U.S. export figure for the commodity to derive export value.
NASS does not provide production statistics for processed agricultural products
such as pasta. For these products, supplemental data from the 2002
Census of Agriculture and the Department of Commerce's 2002 Economic
Census, Subject Series, Manufacturing
Product Summary have been used to refine State export estimates.
Estimates of U.S. State exports also are made by other organizations—U.S.
Census Bureau,
International Trade Administration,
etc. Their estimates are based primarily on Customs data reported at the port and compiled by the Census Bureau. These estimates are based on origin of movement, not production location. Consequently, compared with ERS' estimates, these estimates for agricultural commodities tend to inflate the relative exports of port States and undercount those of inland States, where farm commodities often originate. For a complete discussion of the origin of movement series, see Census' State Export Data Series.
Final Destinations of Agricultural Imports
Although U.S. port of entry data are available for agricultural
imports, State-of-destination data are not available. Consequently,
agricultural imports cannot be tracked to their final destinations
by State.
