Source: The Bureau of Labor Statistics (BLS) develops productivity measures
using output and compensation data published by the Bureau of Economic
Analysis (BEA), hours data published by other BLS programs, and capital data
supplied by BEA and U.S. Department of Agriculture. Also see Technical Notes
in this release.
(1) The private business sector covers gross domestic product with the
exception of the output of general government, government enterprises,
non-profit institutions, the rental value of owner-occupied real estate,
and the output of paid employees of private households. The private
nonfarm business sector further excludes farms but includes agricultural
services.
(2) Output per combined units of labor input and capital services.
(3) Gross domestic product originating in the sector, chained superlative
index.
(4) Index of hours at work of all persons including employees, proprietors,
and unpaid family workers, classified by age, education, and gender.
This chained superlative index is computed by combining changes in the
hours of each age, education, and gender group weighted by each group’s
share of the total wage bill.
(5) A measure of the flow of capital services used in the sector. Capital
services measure the services derived from the stock of physical assets
and software. The assets included are fixed business equipment,
structures, inventories, and land.
(6) The growth rates of labor input and capital services are combined by
weighting with their respective shares of current dollar costs, and
aggregating into a chained superlative index.
