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

(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 groupís 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.

	by weighting with their respective shares of current dollar costs,
	and aggregating into a chained superlative index.
