Figure 4-2 Labor Productivity Indices for Selected Transportation Industries: 1990–2010
NOTES: Bureau of Labor Statistics developed labor productivity indexes for all manufacturing and retail trade of the North American Industry Classification System (NAICS) industries as well as selected mining, transportation, communications and services industries. Data in this table are not comparable to the data published in previous editions of the report due to change in base year of the index from 1997 to 2002.
