National Symmetric Input-Output Tables: Aggregation Level L

The Industry Accounts Division of Statistics Canada publishes annual supply and use input-output (I-O) tables. While these rectangular, industry by commodity closely reflect actual economic transactions, certain analytical and modeling purposes, however, require symmetric industry-by-industry I-O tables. The symmetric industry by industry table shows the inter-industry transactions, that is, all purchases of an industry from all other industries including expenditures on imports and inventory withdrawals as well as all expenditures on primary inputs. Similarly, the symmetric final demand table shows all purchases by a final demand category from all other industries, including expenditures on imports and inventory withdrawals as well as all expenditures on indirect taxes.
These tables are available at the L level. Some data suppression is necessary at the L level due to confidentiality requirements. Explanation on the methodology used is provided to the user by contacting the Industry Accounts Division of Statistics Canada.
