The London IO tables provide an overview of activity across sectors and key aggregates (production, consumption and expenditure) as well as the interlinkages between sectors and London’s trade (with the rest of the UK, the EU and the rest of the world).
The IO tables are product x product rather than industry x industry.
The data is for the product definition of sectors, and sector coverage aligns with the 2014 London Business Survey. See https://data.london.gov.uk/gla-economics/london-business-survey-2014/
Explanation of the content of the tables, applications of their use, and details on the methodology are available here: https://www.london.gov.uk/business-and-economy-publications/london-input-output-tables
