KEY: - = Zero or Less than half the unit shown; thus, it has been rounded to zero.
1 Based on 2002 North American Industry
Classification System (NAICS).
2 Ton-miles estimates are based on estimated distances traveled along a
modeled transportation network.
3 Coefficient of Variation.
NOTES: 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. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/publications/commodity_flow_survey/.
