The 2020 United Kingdom Input-Output Analytical Tables (IOATs) are consistent with the 2023 editions of United Kingdom National Accounts Blue Book and United Kingdom Balance of Payments Pink Book.

The 2020 IOATs are derived from the 2020 annual Supply and Use Tables (SUTs). The SUTs provide a picture of the flows of products and services in the economy for a single year and are used to set the level of annual current price Gross Domestic Product (GDP). They show the composition of uses and resources across institutional sectors and the inter-dependence of industries in order to reconcile the production, income and expenditure approaches to the measurement of GDP.

These tables, together with supplementary data and certain economic assumptions (i.e. technology assumptions), have been combined to construct the input-output table. The input-output table describes how products (and primary inputs) are used to produce further products and satisfy final use. The input-output table and its derivative outputs collectively form the IOATs.

Please note that the 2020 input-output table reflects the economy during the Covid-19 pandemic. Users wanting a more “typical” IOT reflecting the UK economy may wish to use the 2019 input-output table instead.
