NOTE: The value of goods measured in the CFS includes the market value of goods used in production and final demand.  Hence the goods may be counted more than once in the production cycle.  The tonnage of products could also be counted multiple times depending on the number times the product is transported in the production and consumption cycle.,,,
S = Estimate does not meet publication standards because of high sampling variability or poor response quality.,,,
1 The Commodity Flow Survey is estimated to capture approximately 80% of the value of goods shipped in the United States and over 70% of tons and ton-miles. ,,,
"2 Other multiple modal combinations include truck and rail, truck and water, rail and water, and other multiple modes.",,,
3 Examples of other modes are bus and recreational vehicle.,,,
