KEY: * 2002 data are preliminary.
(1) To compare economic changes over time, current or nominal values of currencies must be deflated or adjusted for inflation. In the United States, the Bureau of Economic Analysis (BEA) establishes indices to calculate changes between years. These are used to calculate real chained dollars. Annual changes in the indices are chained (multiplied) together to form a time series. Chained dollars, instead of merely reflecting inflation, capture the effect of relative changes in prices and in the composition of output. They also better reflect cyclical fluctuations in the economy. Chained 2000 dollars are the most currently available indices from
BEA for adjusting for inflation.
(2) Multimodal includes the traditional intermodal combination of truck and rail plus truck and water; rail and water; parcel, postal, and courier service; and other multiple
modes for the same shipment.
(3) Modal details for the BTS out-of-scope supplemental data will be available when the final 2002 CFS
data are released in late 2004.
NOTE: The data in this table include the Bureau of Transportation Statistics estimates of out-of-scope missing pieces. These estimates cover logging, farm-based truck shipments, truck imports from Canada and Mexico, rail imports from Canada and Mexico, air cargo imports and exports, water imports and exports, and pipeline crude and petroleum products shipments. These estimates exclude other out-of-scope categories of goods movements for which no reasonable basis for an estimate currently exists including, government shipments, service sector, retail sector, construction sector, transportation service providers, household goods movement,
and municipal solid waste.
