|State of origin||Value||Tons1|
|All other states||152,738||25.6||63,077||12.9|
– Represents an estimate 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 Selected states are sorted in descending order of estimated tons without regard to sampling variability.
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.
