Input-Output tables describe the sale and purchase relationships between producers and consumers within an economy. They can be produced by illustrating flows between the sales and purchases (final and intermediate) of industry outputs or by illustrating the sales and purchases (final and intermediate) of product outputs. The OECD Input-Output database is presented on the former basis, reflecting in part the collection mechanisms for many other data sources such as research and development R&D expenditure data, employment statistics, pollution data, energy consumption, which are in the main collected by enterprise or by establishment, and thus according to industry classifications.

The latest set of OECD Input-Output tables includes matrices of inter-industrial flows of transactions of goods and services (domestically produced and imported) in current prices, for all OECD countries (except Iceland) and 15 non-member countries, covering the years 1995, 2000 and 2005 or nearest years. Tables for four countries (Cyprus*, Malta, Latvia and Lithuania) have been recently added as well as an estimated  table for the EU has a whole.

Through the use of a standard industry list based on ISIC Revision 3, comparisons can be made across countries. Further information for each country and the estimation methodology is available in the document OECD Input-Output Database edition 2006 - STI Working Paper 2006/8.

The database is a very useful empirical tool for economic research and structural analysis at international level. It highlights inter-industrial relationships and covers not only manufacturing but also services. When used in conjunction with other OECD databases on industrial structures, such as STAN Industry Database (STAN), STAN Bilateral Trade Database by Industry and End-Use (BTDIxE) and the STAN Business R&D Expenditures by Industry (ANBERD), it provides a tool for consistent economic analysis of growth, structural change, productivity, competitiveness and employment at both the sectoral and macroeconomic levels (e.g. Productivity Growth in Services Industries).

Increasingly, input-output tables are also being used in environmental analysis; for example, to measure direct and indirect pollutants produced by industrial sectors within an economy and, importantly, 'leakages' between economies (see Carbon Embodiment in International Trade ). For a broad overview of potential uses of 'harmonised' input-output tables, see STI Working Paper 2006/7.
