The U.S. Department of Transportation’s Bureau of Transportation Statistics and the U.S. Department of Commerce’s Census Bureau have released final estimates from the 2012 Commodity Flow Survey. Trucking continues to be the leading transportation modality.
Since the last survey in 2007, tonnage and ton-miles went down 9.9 percent and 11.2 percent, respectively. Value amount for commodities increased by 18.5 percent, but is not adjusted for inflation.
Trucking accounted for 73.1 percent of the value and 71.3 percent of the tonnage for shippers’ cargo. Overall, trucks shipped out 8.1 billion tons of goods valued at $10.1 trillion. Approximately 1.2 trillion ton-miles were traveled to transport the commodities.
Mixed freight led the commodities categories with the largest value of $1.4 trillion, followed by gasoline at $1.2 trillion and electronics and vehicles (including parts), both at $1.03 trillion. The manufacturing industry contributed the most tonnage at 4.2 billion tons, whereas the wholesale industry contributed the most value at $6.1 trillion.
The Commodity Flow Survey, conducted as a partnership of the Bureau of Transportation Statistics and the U.S. Census Bureau, is the primary source of national and state-level data on domestic freight shipments in the United States. The CFS measures domestic freight shipments by American establishments in mining, manufacturing, wholesale, auxiliaries, and selected retail industries.
