What is Input-Output?
The Input-Output framework of the European System of Accounts (ESA 1995) consists of three types of tables:
- supply tables,
- use tables and
- symmetric Input-Output tables.
The tables provide a complete picture of the flows of goods and services (products) in the economy for a given year. They detail the relationship between producers and consumers and the interdependencies of industries.
Supply and Use tables are constructed directly from survey and other data sources where the Supply table provides estimates of the output of a large number of differentiated products by each industry and the Use table provides estimates of the inputs (of goods and services) used by each industry to produce their own output.
The Supply and Use Tables are the basic building blocks, all other Input-Output analyses are derived from them.
Symmetric tables (a.k.a. the analytical tables) represent the modelling aspect of the Input-Output framework. The Scottish Government produces Industry by Industry, Product by Product and Leontief inverse analytical tables.
More detailed background information is available in the main uses section.
This site contains a user guide for people who are relatively new to Input-Output.
Starting with an overview, there are separate pages describing the Supply table, the Use table, the Symmetric tables, and finally the multipliers, including a guide to their appropriate use.
The guide also contains information about the data sources used in the compilation of the tables and a glossary of terms.
The downloads page contains the full 128 industry matrices in excel and pdf format, in addition to working papers and other documents on the uses of the I-O tables.
Contains information about the Scottish Government Input-Output table development plan.
