INPUT OUTPUT TABLES 2006–07
are consistent with those published in the December 2009 release of the Australian System of National Accounts, 2008–09 (cat. no. 5204.0) which also included significant historical revisions to all National Accounts series. As a result of these changes there are significant differences between the levels of the main economic aggregates published in the 2006–07 IO tables when compared to previous releases. Users should take care when trying to compare these data items between reference years as input output tables are not compiled as a time series.
The 2006–07 release of the Input Output tables contains an additional table for the Electricity Margin on Supply.
IMPLEMENTATION OF SNA RECOMMENDATIONS
The implementation of SNA08 recommendations in this release changes the measurement of a number of components in the Australian System of National Accounts (ASNA) without changing the structure of the accounts. The changes that impact on the Input Output Tables are listed below:

IMPLEMENTATION OF BPM6 RECOMMENDATIONS
The impact of implementing BPM6 recommendations in this release are listed below:
INTRODUCTION OF ANZSIC06
The ANZSIC classification was revised in response to the changing structure and composition of the economy, changing information demands and to align with the fourth revision of the International Standard Industrial Classification. For a detailed discussion of the ANZSIC06 changes see the Australian and New Zealand Standard Industrial Classification 2006 (cat. no. 1292.0) at
Australian and New Zealand Standard Industrial Classification (ANZSIC), 2006 – Class Change Tables, 2006 (cat. no. 1292.0.55.003) at
These changes have had a significant impact on the building blocks of the IO tables i.e. Input Output Industry Group (IOIG) and Input Output Product Classification (IOPC). For example, the dimensions of the industry by industry and industry by product tables will be 112 rows by 112 columns for 2006–07 compared to 109 by 109 for 2005–06.
CHANGES TO IOIGS
The introduction of ANZSIC06 saw many changes to industries at all levels of the classification. As the IOIG aligns to the ANZSIC at a combination of the sub–division and group level it was necessary for the ABS to review the IOIG classification. The outcome of the review was a new IOIG classification which contained many differences to the previous IOIG. In some cases industries remain the same but many industries were either split or merged with other smaller industries and in some cases new industries were formed. The most basic change was the actual number of IOIGs which increased from 109 to 112 under the new classification. Users should note that the tables only report for 111 IOIGs as two industry groups were combined for confidentiality reasons. Table 1 provides a summary of the extent of the changes to the IOIG showing that just over one in five IO industries remained unchanged as a result of ANZSIC06 implementation. Full concordances illustrating the changes between the IOIG(2005) and IOIG(2009) are provided in Table 40 of this release.

Some specific examples of the changes to IOIG include:
CHANGES TO IOPG AND IOPC
As the IOPC is an Industry of origin classification, where a product is classified to the industry based on where the primary producer of that product is classified, the changes to the ANZSIC also necessitated a review of the IOPC. One of the most obvious changes to the IOPC for 2006–07 is the number of IOPCs, which reduced to 1284 compared to 1416 in 2005–06. In contrast, there was a small increase in the number of IOPGs in the classification from 109 to 112. These changes will affect all tables showing product level information and a number of detailed commodity tables that are expected to be released in February of 2011.
The types of changes to the product classification are similar to that experienced by the industry classification with some products remaining unchanged, some being split into two or more products and other categories being merged. Table 2 illustrates that the IOPG changes were the same as the IOIG. However, the number of IOPCs that experienced no change between reviews was approximately 45%.

Some specific examples of the changes to the IOPC include:
Details of concordances between ANZSIC06 and the IOIG classification, and concordances comparing IOPG(2005) to IOPG(2009) and IOIG(2005) to IOIG(2009) are provided in Table 40.
CHANGES TO TABLES IN THIS RELEASE
This release includes an additional table from last year, Table 34 details Electricity Margin on Supply by Product Group by Using Industry and Final Use category. Users should note that as a result of the addition of the Electricity Margin table the numbering of the Margins and Taxes tables has also changed from previous versions. The list of table numbers and titles in this release are provided below:
