KEY: R = revised.

^a Based on the number of paid hours.

^b The average weekly hours were assumed to be constant for air transportation industries; therefore, the output per hour worked and the output per employee measures are identical.

^c Full-time and part-time employees are counted equally. Hence, these data do not reflect output per full-time equivalent employee.

NOTE

BLS 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. Indexes for petroleum pipelines and bus (class I) systems were created under the Standard Industrial Classification (SIC) system but have not yet been developed under NAICS. Productivity measures for NAICS start in 1987.
