(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
(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 groups 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 intellectual property products.
(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.
