This dataset provides statistics on domestic Input-Output tables describing 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 domestic input output tables are covering various industry sectors such as agriculture, finance, real estate, heath, retail and more. The OECD Input-Output database reflects in part the collection mechanisms for many other data sources such as Research and Development 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.
