Geographic Reports: State Summary Tables

This section presents two state-specific tables on commodity movements originating in each state. The first table for each state summarizes shipments by major commodities, major destinations, distance, and modes of transportation. Data on the mode of transportation are aggregated. For example, the truck category includes for-hire, private, and a combination of both; the air category includes truck and air. Note that each states share of total U.S. shipments is calculated using both final state data and preliminary national data measured in the CFS.

Because CFS data are estimates based on a sample, the data are subject to sampling errors. The second table for each state provides the 90-percent confidence interval for each estimate. We can say, with about 90 percent confidence, that this interval contains the value that would have been obtained by averaging the results from all possible samples of the same size and design. Appendix B discusses data reliability in more detail.
