U.S. Transportation and Economic Trends
On July 27, 2018, the Bureau of Economic Analysis (BEA) released the results of the comprehensive, or benchmark, revision of the national income and product accounts (NIPAs) which resulted in many changes relative to previously published results.
Passenger miles is the summation of all modes from table 1-40 less transit motor bus and demand response.
Ton-miles from 1997-2011 is the summation of all modes from table 1-50.
Chained (2012) dollar series are calculated as the product of the chain-type quantity index and the 2012 current-dollar value of the corresponding series, divided by 100. Because the formula for the chain-type quantity indexes uses weights of more than one period, the corresponding chained-dollar estimates are usually not additive. The residual line is the difference between the first line and the sum of the most detailed lines.
To make all the data comparable, all index data are using year 2012 as the base year.
This table is not comparable with the previous' version.
Chained 2005 dollars estimates for earlier years can be found in the 2013 edition of NTS, table 3-10.
Chained 2007 dollars estimates for earlier years can be found in the 2014 edition of NTS, table 3-10.
Chained 2009 dollars estimates for earlier years can be found in the 2015 edition of NTS, table 3-10.
KEY: R = revised.
