Estimates are based on preliminary data from the 2012 Commodity Flow Survey. Because of rounding, estimates may not be additive

KEY:
Z - Less than half the unit shown. For the 2012 CFS, represents an estimate that is between zero and half the unit shown, thus, has rounded down to zero.
(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.
(3) Coefficient of Variation.

NOTES: These data are preliminary and are subject to change; they will be superseded by data released in later reports. Value-of-shipment estimates have not been adjusted for price changes. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables.
