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 Standard Classification of Transported Goods.
2 Coefficient of Variation.
3 Estimates exclude shipments of crude petroleum (SCTG 16).

NOTES: Rows are not shown if all cells for that particular row have no values. For example, specific commodity group by mode rows are not shown in this table becasue there are no data for those rows. Value-of-shipment estimates have not been adjusted for price changes. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
