"KEY: 
— Represents data cell equal to zero or less than 1 unit of measure.  
S Estimate does not meet publication standards because of high sampling variability or poor response quality.",,,,,,,,,,,
"(1) Ton–miles estimates are based on estimated distances traveled along a modeled transportation network. See ""Mileage Calculations"" section for additional information.
(2) Estimates exclude shipments of crude petroleum (SCTG 16).",,,,,,,,,,,
"NOTES:  Value–of–shipments estimates have not been adjusted for price changes. Appendix B tables provide estimated measures of sampling variability. The Introduction and appendixes give information on confidentiality protection, sampling error, nonsampling error, sample design, and definitions. Links to this information on the Internet may be found at www.census.gov/cfs. 
Coverage for the 2002 Commodity Flow Survey (CFS) differs from the previous surveys due to a change from the 1987 Standard Industrial Classification System to the 1997 North American Industry Classification System and other survey improvements. Therefore, data users are urged to use caution when comparing 2002 CFS estimates with estimates from prior years.",,,,,,,,,,,
