This principle is generally applied through the definition of each IOPC item in terms of the ANZSIC industry in which it is primarily produced. Homogeneity of inputs - each product or product group should consist of items that have similar input structures or technology of production.The overall principles for the preparation of such an industry-of-origin product classification include: 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 IOPC is an industry-of-origin product classification that has been specifically developed for the compilation and application of Australian (I-O) tables. I-O tables are published at this level of product classification.

IOIGs are based on the Australian and New Zealand Standard Industrial Classification (ANZSIC) both the I-O tables and Product Details tables are published at this level of industry. IOPGs are groups of IOPCs aggregated to the IOIGs to which they are primary. It shows Australian production, imports, intermediate usage, final usage, exports, margins and taxes less subsidies on products. This publication presents information on supply and use by detailed product item based on Input-Output Industry Group (IOIG), Input-Output Product Group (IOPG) and Input-Output Product Classification (IOPC). These are reflected in the updated Industry and Product concordance on the Methodology page. These are minor changes only to improve the description and numerical consistency of products. A small number of other IOPC codes and descriptions have been updated due to ongoing maintenance of the classifications.IOPC 67110020 Residential caravan park operation and residential property body corporate or strata corporation services has been split into 67110050 Residential caravan park operation and residential property body corporate or strata corporation services for owner-occupiers and 67110060 Residential caravan park operation and residential property body corporate or strata corporation services for actual rent.IOPC 67110010 Ownership of Dwellings has been split into 67110030 Imputed rent for owner-occupiers and 67110040 Actual rent for housing.IOIG/IOPG 6701 Ownership of Dwellings has been split into 6700 Imputed rent for owner-occupiers and 6701 Actual rent for housing.To align better with the international standard for Supply-Use and Input-Output tables, the industry and product classifications for Ownership of Dwellings have been updated as follows:.The Product Details tables contain Australian production, imports, margins, taxes, subsidies, intermediate and final usage, and exports of over 900 products. The I-O tables include basic transaction tables, coefficients, industry flow and margins tables. This publication contains the I-O tables and I-O Product Details tables for 2021-22. The data published in this release is consistent with the latest release of the Australian System of National Accounts. They provide detailed information about the supply and use of products in the Australian economy, and the structure of and inter-relationships between Australian industries. The Input-Output (I-O) tables are part of the Australian National Accounts, complementing the quarterly and annual series of national income, expenditure and product aggregates.
