Estimates are based on data from the 2007 Commodity Flow Survey. Because of rounding, estimates may not be additive.

KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality. - = 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.
2 Coefficient of Variation.
3 "Truck" as a single mode includes shipments that were made by
only private truck, only for-hire truck, or a combination of private truck
and for-hire truck.
4 Estimates for pipeline exclude shipments of crude petroleum.
NOTES: Rows are not shown if all cells for that particular row have no values. For example, specific state by mode rows are not shown in this table because there are no data for those rows. Value-of-shipment estimates are reported in current prices. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables.
