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 "Truck" as a single mode includes shipments that were made by
only private truck, only for-hire truck, or a combination of private truck
and for-hire truck.
3 Estimates for Pipeline exclude shipments of crude petroleum.
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 confidentially 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.
