Explanatory notes covering the basic structure of input-output and associated tables, special treatments adopted in compiling input-output tables and using input-output tables for analysis are shown in
Australian National Accounts: Concepts, Sources and Methods (cat. no. 5216.0), Chapter 9, The Input-Output Framework.

Explanatory notes relating to the input-output tables covering the I-O approach to compiling the national accounts and sources and methods are shown in
Australian National Accounts: Concepts, Sources and Methods (cat. no. 5216.0), Chapter 12, Input-Output Tables.

The Input-Output spreadsheets here contain data rounded to the nearest 1 million dollars. This rounding has been applied as we do not have confidence in the statistical accuracy of the estimated values for cells less than $500,000. In the compilation of input-output tables various modelling techniques are used to populate the tables because directly collected information is not available for every cell in the input-output table. As a consequence of these modelling techniques very small values may be estimated in certain cells but the statistical accuracy of these data cannot be verified to a sufficient degree. Through rounding the amount of statistical noise is reduced and users can focus more directly on cells of significance.

However, some users of input-output data apply the data in large and sophisticated models which often require unrounded source data for them to work effectively. In these situations the ABS is willing to consider supplying unrounded data for certain input-output tables. Please contact the ABS for more information and a discussion on the relevant statistical issues.
