22.95    The I-O compilation begins with the finalisation of the S-U tables, when the balanced S-U levels are disaggregated to I-O levels. This results in unbalanced I-O tables which are then balanced using the product flow method. The product flow method involves a number of steps followed by a quality assessment process at strategic points to check data quality and consistency.

22.96    The figure below shows the steps undertaken in the I-O compilation process. The steps are then described in more detail.

Step 1: Collect source data

22.97    Obtain the S-U tables and previous I-O tables.

Step 2: Reconciliation and disaggregation

22.98    Balanced S-U tables are disaggregated in order to populate the I-O tables, ensuring consistency with the rest of national accounts published aggregates.

22.99    Much of the initial data used to populate the S-U tables is classified at the IOPC and IOIG levels, and then aggregated to the SUPC and SUIC levels. It is at this level that the balancing process of the S-U table is undertaken in order to produce balanced GDP estimates for the national accounts. It is necessary to then disaggregate the S-U products and industries to the I-O level in order to begin production of the I-O tables.

22.100    The disaggregation of the S-U level to the I-O level does not necessarily result in the same I-O distribution, compared with the initial I-O level data. This is due to the balancing being undertaken at the S-U level, and any adjustments made at that level may result in a different S-U level total than the initial total. This difference has to be distributed back to the I-O level and is done in several ways, depending on the component.

22.101    The following table outlines how the S-U level components are disaggregated to the I-O level.

GFCE data are compiled according to the Classification of the Functions of Government - Australia , which is mapped to IOPC using historical input-output weights and aggregated for the S-U tables.

Any adjustments made during the S-U balancing process are applied to the appropriate IOPC based on the intelligence for the decision. If detailed information is not known, it is allocated based on previous I-O tables.

Gross fixed capital formation
 

GFCF data are compiled according to asset type by sector. With the exception of machinery and equipment, all asset types align with the IOPC. Machinery and equipment is disaggregated to the IOPC level based on previous years’ I-O tables, and converted into current-year prices using price indexes.

Any adjustments applied during the balancing process are based on an informed assessment of how and why the imbalance has occurred. In cases where the required level of detail cannot be sourced, the allocation is based on previously-balanced I-O tables or the original proportions of the correspondence.

Changes in inventories
 Changes in inventories is distributed across IOPCs based on how changes in inventories is distributed across IOPCs in the latest set of balanced I-O tables.
Exports of goods and services
 

International trade data is mapped to the IOPC using the Australian Harmonised Export Commodity Classification (AHECC to IOPC correspondence). Further adjustments based on Balance of Payments data are made to the relevant IOPCs where appropriate.

Further adjustments at the IOPC level may be required for product and industry balancing purposes. All such adjustments are offset to ensure that total exports remain unchanged.

Imports of goods and services
 

International Trade data is mapped to the IOPC using the Harmonised Tariff Item Statistical Classification (HTISC to IOPC correspondence). Further adjustments based on Balance of Payments data are made to the relevant IOPCs where appropriate.

Further adjustments at the IOPC level may be required for product and industry balancing purposes. All such adjustments are offset to ensure that total imports remain unchanged.

22.102    Once the disaggregation is completed it is necessary to reconcile (or confront) these results with additional information to ensure the distribution is coherent. The data sources, in addition to the main data sources used to compile the S-U tables, used in this reconciliation process are obtained from the following:

  • ABS data:
    • Australian Industry Statistics case study data;
    • Value of Agricultural Commodities Produced data;
    • Mineral and Petroleum Exploration data;
    • Retail Trade;
    • Quarterly Business Indicators;
    • Building Approvals data;
    • Engineering Construction data;
    • Private Sector Construction data;
    • Water Account data;
    • Motor Vehicle Use data;
    • Tourist Accommodation data;
    • Household Expenditure data; and
    • occasional publications;
  • Office of the Chief Economist;
  • Australian Bureau of Agricultural Resource Economics and Sciences:
    • Agricultural Commodities; and
    • Australian Forest and Wood Products Statistics;
  • Department of Climate Change, Energy, the Environment and Water:
    • Australian Petroleum Statistics;
  • State departments of primary industries;
  • Australian Prudential Regulatory Authority;
  • Reserve Bank of Australia;
  • Australian Taxation Office;
  • Medicare statistics;
  • annual reports;
  • press and internet articles;
  • private industry analysis; and
  • industry body commentary.

22.103    The level of detail used in the disaggregation and reconciliation processes will vary depending on the component and its data source. The aim is to use the most detailed information where available. For example, detailed information is available at the IOPC level for international trade in goods statistics. However, IOPC level detail is not available for international trade in services or Government Finance Statistics. In this case, weights from the previous year’s I-O tables are applied to derive I-O estimates.

22.104    The disaggregation (and reconciliation) process will result in imbalances at the I-O levels. These imbalances are resolved during the balancing process described in the steps that follow.

Step 3: Alignment with the ASNA

22.105    The initial data at IOPC level is reviewed against quality measures (see next section for more details). This initial data quality assessment is designed to ensure that I-O estimates are fully aligned with the Australian System of National Accounts available at the time that the I-O tables are compiled.

22.106    Given the importance of margins in the I-O framework, detailed ratio analysis are undertaken to review the product allocation of trade margins.

22.107    Adjustments are implemented where required.

Step 4: Industry level analysis

22.108    The I-O tables are assessed against the quality measures via an industry view and adjustments made where necessary. The industry view assesses Australian production of products by each industry and the use of each product by other industries as part of the production process.

Step 5: Row balancing at purchasers’ prices

22.109    The supply of each product is balanced against the intermediate and final use of the product by a manual process using the data sources listed in step 2 above.

22.110    A principal edit undertaken in the compilation of I-O tables is to reconcile the flow of products through the productive process. Backward linkages are reconciled to ensure the process of products through the productive process is logical. For example, the Australian production of raw milk is compared to the intermediate use of products produced by the dairy manufacturing industry in milk and dairy product production. As a product is transformed or processed, the value of output should increase due to the increase in value added.

22.111    When all products are balanced at purchasers’ prices (PP), the data are assessed against the quality measures and adjustments made where required.

Step 6: Allocation of margins, taxes and subsidies and derivation of the Basic Price

22.112    Once the I-O tables are manually balanced at purchasers' prices (PP), the use categories at basic prices (BP) are modelled using the basic relationship PP = BP + MTS where MTS represents Margins, Taxes and Subsidies on products.

22.113    The disposition of each margin, tax or subsidy across the use categories is driven by a number of general rules. These rules are applied to all products except those with specific characteristics (see below) in order to ensure the resulting disposition of MTS is logical and coherent. In the use categories, for example, the retail margins can only be allocated to HFCE while wholesale margins can be allocated to all use categories (including intermediate use) except GFCE and inventories.

22.114    In a number of instances, the standard disposition of MTS is overwritten by special rules. These special rules are applied to products with specific use characteristics and ensure a better allocation of MTS for these products. An example of a special rule relates to goods consumed by tourists which can attract retail margins in exports.

22.115    Margins, taxes and subsidies are independently allocated across the use categories on a proportional basis according to the general and special rules. The total MTS by product is therefore allocated to all use categories for each product, first using the PP and then on BP once derived.

22.116    The BP is derived from the PP by subtracting MTS in intermediate use and final use. Because MTS are allocated independently, the resulting BP tables are unbalanced. A constrained optimisation process is used, once large imbalances have been resolved manually, to balance products and industries in the intermediate use matrix.

22.117    The different margins, taxes and subsidies are added to the BP in a cumulative manner. In most cases, transport margins will be applied before wholesale margins which will themselves be applied before retail margins. For practical reasons the incremental disposition of MTS is not applied but the basic price is assumed to be a better allocator for MTS. This is particularly true for products attracting a lot of retail margins and for which the inclusion of these margins would distort the disposition of other MTS.

22.118    Once derived, the BP is used to allocate MTS across the use categories. Manual adjustments are made where required. This process is repeated twice in order to gradually refine the disposition of MTS and the resulting BP.

22.119    When all products are balanced at BP the data are assessed against the quality measures and adjustments made where required.

Step 7: Produce basic and derived I-O tables

22.120    The next step is to produce basic and derived I-O tables. Quality checks are again run to assess data quality, and to check that publication standards have been applied to the tables for release.

22.121    The SNA68 transport margin adjustment is made (see section on the SNA68 transport margin adjustment at beginning of this chapter).

22.122    The alternate view tables are then prepared. The treatment applied to compile the alternate view removes the negative effect of the c.i.f./f.o.b. adjustment in imports (see section on c.i.f./f.o.b. adjustment for details).

22.123    The product details tables are then prepared.

22.124    All tables for release are assessed against quality measures and any corrections made as required.

Step 8: Disseminate I-O tables, alternate view tables and product details publication

22.125    Publication tables are disseminated on the ABS website. The last quality check is run to review the publication production cycle, and to identify and document improvements for the following cycle

Quality measures

22.126    Twenty quality measures are applied at the various steps in the compilation process described above. The quality measures include internal consistency checks and checks for consistency with published national account aggregates. Most of the quality measures are assessed at every gate with a few exceptions. The complete list of quality measures include:

  1. all three measures of GDP are equal when aggregated from the I-O tables;
  2. supply matches use in all rows (after product balancing);
  3. application of the SNA68 TMA does not affect PP overall estimates;
  4. the latest appropriate data for the reference period has been used;
  5. there are no negative values in supply;
  6. estimates match published estimates in the Australian National Accounts for the relevant reference period;
  7. known problems from previous I-O cycles have been resolved;
  8. c.i.f./f.o.b. adjustments have been applied correctly;
  9. there are no inventories of services and no margins attributed to services products;
  10. GST and retail margins are consistent with HFCE;
  11. domestic exports do not exceed production unless stock is drawn from Inventories;
  12. re-exports do not exceed imports unless stock is drawn from Inventories;
  13. coverage and specialisation ratios are sensible and consistent with previous I-O tables;
  14. supply is consistent with use for top 50 IOPCs;
  15. the COE/TIU and GOS/TIU ratios are plausible;
  16. inventory levels are sensible in relation to supply at basic prices;
  17. distribution of supply confronted with previous cycle is plausible;
  18. distribution of retail and wholesale margins is coherent;
  19. supply and final use column totals have not been changed; and
  20. issues identified at previous steps have been addressed.
