Supply and Use and Input-Output Tables

The supply and use tables focus on measuring the productive structure of the economy. They trace production of commodities by domestic industries, combined with imports, through their use as intermediate inputs or as final consumption, investment or exports. The system provides a measure of value added by industry—total output (or sales) less intermediate inputs. These tables can be used to calculate economy-wide gross domestic product (GDP)  either directly, by summing value added over the industries, or indirectly, by  summing to the economy-wide cost of primary inputs (income-based GDP) or by computing the grand total of the flow of commodities into final demand categories (expenditure-based GDP)—the link to the national income and expenditure accounts.

While the supply and use tables closely reflect actual economic transactions, certain analytical and modeling purposes, however, require symmetric industry-by-industry tables. These symmetric industry-by-industry tables are referred to as input-output tables. The input-output tables allow the analyst to explore "what if?" questions at a fairly detailed level, exploring the impact of exogenous changes in final demand on output while taking account of the interdependencies between different industries and regions of the economy and the leakages to imports and taxes… (more)
