Introduction
This publication presents information on supply and use by detailed product item based on the Input-Output Product Classification (IOPC). A separate publication Australian National Accounts: Input-Output Tables (cat. no. 5209.0.55.001) provides a comprehensive range of Input-Output (I-O) flow and coefficient tables. The data published in both of these releases is consistent with the 2017-18 release of the Australian System of National Accounts (cat. no. 5204.0).
The publication comprises a list of IOPC product items and shows Australian production, imports, intermediate usage, final usage, exports, margins and taxes less subsidies on products in 2016-17. Several aggregates shown in this spreadsheet can be directly related to Tables 1, 2 and 3 of the Australian National Accounts: Input-Output Tables (cat. no. 5209.0.55.001) for 2016-17.
Classifications
The IOPC is an industry-of-origin product classification that has been specifically developed for the compilation and application of Australian (I-O) tables. Because the I-O system describes the production and subsequent use of all goods and services, an I-O product classification needs to be defined in terms of characteristic products of industry sectors. The overall principles for the preparation of such an industry-of-origin product classification include:
- homogeneity of inputs - each product or product group should consist of items that have similar input structures or technology of production. This principle is generally applied through the definition of each IOPC item in terms of the ANZSIC industry in which it is mainly produced
- homogeneity of disposition - each product or product group, having satisfied the first criterion, should consist of items that have similar patterns of disposition or usage. This principle is applied by reference to the description of source data items and information about the transport, distribution and product taxation margins applying to particular products.
The IOPC used in this publication is consistent with the 2006 edition of the Australian and New Zealand Standard Industrial Classification (ANZSIC).
The IOPC has over 900 individual product items. For confidentiality and data availability reasons the values of some of these detailed products have been suppressed (shown as 'n.p.'). The practice of aggregating product details for confidentiality, used in past, has not been applied in this release.
Structure of the IOPC
The structure of the IOPC arises from its industry-of-origin basis where each product item is shown according to the industry in which it is primarily produced.
This structure is implemented in the IOPC by the adoption of ANZSIC classes as the basis for defining IOPC items. IOPC items are identified by an eight digit code with the first four digits typically referring to the ANZSIC class to which the item is primary and the last four digits the product number. Details of ANZSIC codes and their relationship to the I-O industry groups, and other industry and commodity classifications are shown in Table 2 of this release.
