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 Estimates represent activity for a given mode across single
and multiple mode shipments. For
example, "Truck" ton-miles includes total ton-miles for shipments
moving only by truck plus ton-miles for truck segments of multiple mode
shipments.
2 Ton-miles estimates are based on estimated distances traveled along a
modeled transportation network. See "Mileage Calculations" section
for additional information.
3 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

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.
