KEY: S = Withheld because estimate did not meet publication standards.

Z = Rounds to zero.

(1) Ton-miles estimates are based on estimated distances traveled along a modeled transportation network. See “Mileage Calculations” section for additional information.

(2) “Truck” as a single mode includes shipments that were made by only private truck or only for-hire truck.

(3) Estimates for pipeline exclude shipments of crude petroleum (SCTG 16).
