Table Version
NOTES: For consistency, aviation
passenger-miles of travel (pmt) includes air carrier aviation only, as general
aviation pmt 2002 data were not available when this report was prepared. See table 1-2 in appendix B for
definitions.
To
make it easier to compare data of differing magnitudes over time, the Bureau of
Transportation Statistics divided the data for all years in each category (see
corresponding tables in appendix B) by the initial year value and multiplied
the result by 100.
