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 Shipments are grouped into distance categories based on Great Circle Distance (GCD). GCD is the shortest distance between 2 points on the surface of a sphere over the surface of that sphere.
2 Ton-miles estimates are based on estimated distances traveled along a modeled transportation network. See "Mileage Calculations" section for additional information.
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.
