Table 4c. Shipment Characteristics by Shipment Weight: Percent of Total for 2007 and 2002
[Estimates are based on the 2007 and 2002 Commodity Flow Surveys. Because of rounding, estimates may not be additive]

KEY: - = Zero or Less than half the unit shown; thus, it has been rounded to zero.
1 Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
NOTES: Value-of-shipment estimates are reported in current prices. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
