The annual input-output (I-O) accounts show how U.S. industries interact; specifically, they show how industries provide input to, and use output from, each other to produce the nation’s gross domestic product (GDP). This detailed information on the flows of the goods and services that comprise the production process of industries is presented in two standard tables: the standard I-O make table and the standard I-O use table.
The "Make of Commodities by Industries before Redefinitions" details the commodities produced by industries. The rows in the make table show the commodities produced by each industry, and the columns show the industries that produce each commodity. Commodity output is valued at producers’ prices, that is, at the market prices that producers receive including the commodity taxes they collect (e.g., sales taxes).
The "Use of Commodities by Industries before Redefinitions" details the commodities consumed by industries and final users. Commodity consumption is also valued at producers' prices. Each row details both the intermediate consumption by industries of a specific commodity and the final consumption of the commodity. Each industry column of the standard I-O use table details the industry's production function, including the value of the industry's total output, the mix of commodities it consumes to produce this output, and the value added by the industry’s labor and capital producing this output. The final use column of the standard I-O use table detail the commodity composition of the final use components of GDP.
