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 Based on 2002 North American Industry Classification System (NAICS). NAICS is a hierarchical coding system and certain codes may be nested. For example, estimates for value and tons summed from NAICS codes 4231 through 4239 equal the estimates of values and tons for NAICS code 423. This also applies to the percentages shown in this table. For example, NAICS code 31-33 Value percentage of 49.1 is a result of the summed percentages from NAICS codes 311 through 339 which comprise NAICS code 31-33.
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/.
