The Symmetric Input-Output (I-O) Tables are derived from the preceding Supply and Use Tables. Completing the transformation into these tables first requires the calculation of the Use Table at basic prices. As described in earlier chapters, Supply at basic prices is transformed into purchasers' prices by the addition of Margins and Taxes less Subsidies on products. To transform the Use Table at purchasers' prices into basic prices requires the removal of these Trade Margins and Taxes less Subsidies across industries, products, Final Consumption, Capital Formation and Exports. In order to do this, Use Tables of Trade Margins, of Taxes, and of Subsidies are first calculated, and these are then used to transform the Use Table from purchasers' prices to basic prices. Once the Use Table at basic prices is calculated, we disaggregate it into domestic inputs (uses) and imported inputs. In total, there are three Use Tables at basic prices, one for total inputs, one for domestic inputs and one for imported inputs. These three tables, along with the Table of Trade Margins and the Table of Taxes less subsidies, form what are known as the Intermediate Tables for the I-O Tables.
There are three I-O Tables; one for each of the Use at basic prices tables, a totals table, a domestic I-O table, which refers to the consumption of domestically produced products and an imports I-O table, which refers to the consumption of imported products. The symmetric tables present the Use Tables as product by product (as opposed to product by industry) and can be seen as a blending of the Supply Table and the Use Table into a single table. The tables allow for the examination of both inputs (columns) and outputs (rows) simultaneously, and its main value lies in being able to examine the use of products in the production of other products within the Irish economy.
A summary of the I-OT for domestic product flows is presented in table 5.1 below. The summary table easily highlights the tables' symmetry, and how the inputs are equal to the outputs across product categories.

The Domestic I-O Table, the summary of which is shown in table 5.1 above, is in turn used to calculate Coefficients of domestic product flows and the Leontief Inverse of domestic flows with multipliers for other inputs. The Table of Coefficients explains the direct input requirements per unit of output, while the Leontief Inverse shows the inputs required per unit of final demand. If there is an increase in demand for a particular product, we assume there will be an increase in output of that product (direct effect), but there will also be an increase in demand for other products used in the production of that first product (indirect effect). This table measures the direct and indirect impacts on the economy from the increase in demand for domestic output of a given product.
