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 combination of private Truck and
for-hire Truck.
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.
