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 Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
³ Coefficient of Variation.
⁴ ""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.
⁵ 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 mode have no data. For example, since Denver-Aurora-Boulder by "Water" has no data for any shipment weight group, the entire mode of "Water" for that area was removed from this table. However, if a mode has at least one row of data for one of the shipment weight groups, then the entire mode is shown even though there may be rows absent of data within that mode. For example, Denver-Aurora-Boulder by "Other and unknown modes" has a row absent of data for the shipment size of "More than 100,000 lbs" but does have data for the other shipment weight groups under that mode so it will be shown in its entirety.
