KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality. - = Zero or Less than half the unit shown; thus, it has been rounded to zero.

¹ Commodity Flow Survey (CFS) geographic areas were drawn from a subset of Combined Statistical Areas (CSAs) and Metropolitan Statistical Areas (MeSAs) as defined by the Office of Management and Budget (OMB). However, CFS metropolitan areas are divided into their state parts when they include more than one state. In addition, the CFS also utilizes a unique geography referred to as, "remainder of state," to represent those areas of a state not contained within a separately published metropolitan area for the CFS (as opposed to not part of any Core-Based Statistical Area (CBSA) as defined by OMB). Because of the differences in the CFS geography, as compared to OMB defined geography, caution should be exercised when comparing CFS estimates to other estimates of similar geography.
² Standard Classification of Transported Goods.
³ Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
⁴ Coefficient of Variation.
⁵ Estimates exclude shipments of crude petroleum (SCTG 16).
⁶ "Truck" as a single mode includes any shipment that was made by private truck only, by for-hire truck only, or by a combination of private and for-hire truck.
⁷ Estimates for pipeline exclude shipments of crude petroleum.

NOTES: Value-of-shipment estimates are reported in current prices. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/publications/commodity_flow_survey/.
Rows are not shown if all cells for that particular row have no value. For example, Dallas-Fort Worth, TX by Base metal and machinery (31-34) by Water has no data for any shipment characteristic therefore the entire row is not shown. Also, entire commodity groups are not present if there is no such data for that commodity group by area. For example, Washington-Arlington-Alexandria, DC-VA-MD-WV (DC part) by Coal and petroleum products (15-19) has no data for any mode therefore the entire commodity group is not shown.
