Figure 5 in turn presents a national IOT in a simple way by aggregating all industries into 8 sectors. In the rows we can see the distribution of each sector’s output (the inter-industry transactions and sales to final consumers). In the columns we can see the inputs required in production by each sector, plus the value added generated domestically, which is reflected in the employees’ compensation, capital income, and indirect business taxes. National IOTs allow us to understand the interaction between domestic industries.
