The US Census Bureau has released the results of the 2012 Commodity Flow Survey.

The Commodity Flow Survey is conducted every five years as part of the Census Bureau’s economic census. The survey, a partnership with the U.S. Department of Transportation’s Bureau of Transportation Statistics, is the primary source of national, state and selected metropolitan areas statistics on domestic freight shipments. It provides information on the origin and destination, value, weight, mode of transportation, distance and ton-miles of commodities shipped.

For the entire set of results, visit the Commodity Flow Survey and the data in the American FactFinder.
