Modelled estimates of usage
In the compilation of Input-Output (I-O) tables various modelling techniques are used to populate the tables because directly collected information is not available for every cell. As a consequence of these modelling techniques very small values may be estimated in certain cells and the statistical accuracy of these data cannot be verified.
Rounding of estimates and lower level estimates
The details contained in this publication represent the lowest level at which information from the I-O tables Australian National Accounts: Input-Output Tables (cat. no. 5209.0.55.001) is available. The I-O spreadsheets here contain data rounded to the nearest one million dollars at the total by product level for supply and use, in both basic prices and purchasers' prices. This rounding has been applied as the ABS does not have confidence in the statistical accuracy of the estimated values for cells less than $500,000. For analytical purposes the values of margins, taxes and subsidies (used to move from basic prices to purchasers' prices) are displayed to the nearest one million dollars. However, the individual cells in selected spreadsheets have not been rounded to this level and contain values to 3 decimal places. Data at this level should be used with caution as these values are a direct result of various modelling techniques used in their derivation.
Additivity - sum of the components may not equal total
The sum of the components may not equal the reported total in all cases. This has been caused by small values (less than $500,000) being assigned to different industries or products as part of the modelling processes used in the compilation of I-O tables. Cells with a value of less than $500,000, while not displayed in the tables, have been included in the total values. The totals reported, however, relate to the information released in Australian National Accounts: Input-Output Tables (cat. no. 5209.0.55.001) and sum to the same values.
Products combined for confidentiality purposes
The information contained in these product details has been confidentialised. This confidentiality has been applied through the suppression of some values (shown as 'n.p.').
Departures from 2008 SNA
I-O tables depart from the 2008 System of National Accounts (2008 SNA) and from the rest of the Australian national accounts in one main respect, namely the definition of output at basic prices. The departure relates to the treatment of charges incurred in moving goods from their point of production to the final user, where delivery charges relating to delivery by a third party operator arranged by the producer and paid for by the producer and not separately charged to the end user are treated differently in 2008 SNA.
Under the 1968 version of the System of National Accounts (1968 SNA) these charges were excluded from the basic price valuation of the good concerned while under the 2008 SNA treatment the basic price valuation of the good includes these delivery charges. The ABS considers that the change in definition was inappropriate from an analytical point of view and would result in the same product being valued differently depending whether or not the producer charged separately for the delivery of the product. The ABS therefore applies an adjustment to the I-O tables to reallocate delivery charges separably invoiced to transport, so including them in transport margins and reducing basic prices.
In the 2017-18 I-O tables the value of this adjustment is $46.1b. It is applied to industries and products in agriculture, mining and manufacturing and based on questions on collection forms about invoicing arrangements and transport expenses.
The following notes explain the structure of the data in each table
Table 1. Product details
This table shows the Input-Output Product classification (IOPC) detail of key data items. The key data items are further disaggregated on the following tables.
T2 Supply BP
This table shows Australian production at basic prices by Input–Output Product Classification (IOPC) and by Input–Output Industry Group (IOIG). A row in this table represents a product group and a column represents an industry group.
This table shows the margins associated with the supply of domestic and imported products broken down by Input–Output Product Classification (IOPC). These are further disaggregated by Input–Output Industry Group (IOIG) in T4-T17.
This table shows taxes and subsidies on products broken down by Input–Output Product Classification (IOPC). These are further disaggregated by Input–Output Industry Group (IOIG) T19-T23.
T24 Supply PP
This table shows total supply at purchasers’ prices broken down by Input–Output Product Classification (IOPC). These are further disaggregated in T2, T3 & T18
T25 Use of Products BP
This table shows intermediate use at basic prices by Input–Output Product Classification (IOPC) and the components of final demand by Input–Output Industry Group (IOIG). A row in this table represents a product group and a column represents an industry group.
T26 Use of Products PP
This table shows intermediate use at purchasers' prices by Input–Output Product Classification (IOPC) and the components of final demand by Input–Output Industry Group (IOIG). A row in this table represents a product group and a column represents an industry group.
Table 2. Industry and product concordances
The IOIG(2015) to ANZSIC06 table shows the concordance (mapping) between Input Output Industry Groups (IOIG) and Australian and New Zealand Standard Industrial Classification (ANZSIC06).
The IOIG(2005) to IOIG(2009) and IOPC(2005) to IOPC(2009) tables also show the concordance between the 2005 and 2009 IOIG's and the 2005 and 2009 Input-Output Product Classifications (IOPC). IOIG(2005) and IOPC(2005) are based on ANZSIC(93) and IOIG(2009) and IOPC(2009) are based on ANZSIC(06).
The IOPC(2015) to IOPC(2017) table shows the concordance between the 2015 to 2017 Input-Output Product Classifications (IOPC).
The IOPC(2017) to IOPC(2018) table shows the concordance between the 2017 to 2018 Input-Output Product Classifications (IOPC).
The IOPC(2018) to CPI(17th series) table shows the concordance between IOPC(2018) and CPI(17th series) codes. In the I-O tables this shows the concordance for Household Final Consumption Expenditure (HFCE) data to the CPI codes.
The IOPG(2015) to HEC(2015-16) table shows the concordance between the Input-Output Product Group (IOPG)(2015) and Household Expenditure Classification (HEC)(2015-16) codes.
IOIG(2015) to ANZSIC06
In the IOIG(2015) to ANZSIC06 table, IOIG(2015) codes are shown in column A and IOIG(2015) descriptors are shown in column B of the table. ANZSIC codes are shown in column C and ANZSIC descriptors are shown in column D. The ANZSIC codes shown in this table are ANZSIC Class codes.
For example, IOIG 0101, the Sheep, grains, beef and dairy cattle industry is mapped to ANZSIC codes 0141 (Sheep Farming (Specialised)), 0142 (Beef Cattle Farming (Specialised)), 0143 (Beef Cattle feedlots (specialised)), 0144 (Sheep–Beef Cattle Farming), 0145 (Grain–Sheep or Grain–Beef Farming), 0146 (Rice Growing), 0149 (Other Grain Growing) and 0160 (Dairy Cattle Farming).
IOPC(2005) to IOPC(2009)
The IOPC(2005) to IOPC(2009) table shows the 2005 IOPC code in column A with the 2005 IOPC descriptor shown in column B. Column C shows the 2009 IOPC code with the 2009 IOPC descriptor in column E. Column E indicates whether a 2005 IOPC is mapped partially to a 2009 IOPC and is indicated by a 'p' in the column.
For example, the 2005 IOPC 01110010 (Plant nurseries (incl turf)) is mapped partially to the 2009 IOPCs 01110010 (Plants grown undercover), 01120010 (Plants grown outdoors) and 01130010 (Turf).
IOPC(2015) to IOPC(2017)
The IOPC(2015) to IOPC(2017) table shows the 2015 IOPC code in column A with the 2015 IOPC descriptor shown in column B. Column C shows the 2017 IOPC code with the 2017 IOPC descriptor in column D.
IOPC(2018) to CPI(17th series)
The IOPC(2018) to CPI(17th series) table shows the 2018 IOPC code in column A with the 2018 IOPC descriptor shown in column C. Column D shows the CPI 17th series code with the CPI 17th series descriptor in column F. Column G indicates whether a 2018 IOPC is mapped partially to a CPI 17th series code and is indicated by a 'p' in the column.
For example, the 2018 IOPC 01110010 (Plants grown undercover) is mapped uniquely to the CPI 17th series code 543 (Other non-durable household products).
IOPG(2015) to HEC(2015-16)
The IOPG(2015) to HEC(2015-16) table shows the 2015 IOPG code in column A with the 2015 IOPG descriptor shown in column C. Column D shows the partial split of corresponding 2015-16 HEC codes within a 2015 IOPG code. Where it shows a 'p', the 2015-16 HEC code is split between different 2015 IOPG codes. Column E shows the HEC(2015-16) code with the HEC(2015-16) descriptor in column G.
For example, 2015-16 HEC 1001060101 (Crash repairs) and 1001060201 (Vehicle servicing (including parts and labour)) are proportionally split within 2015 IOPG 9401 Automotive repair and maintenance. Where it shows a 'p' in Column D, the 2015-16 HEC code 0302030104 (Other lamb and mutton nec) is split between 2015 IOPG 0101 (Sheep, grains, beef and dairy cattle) and 2015 IOPG (1101 Meat and meat product manufacturing).
There are a number of factors to take into account when using this table. It should only be applied to data at Purchasers prices as it was based on the Household Expenditure Survey (HES) which is collected at Purchasers Prices. The table was compiled from the 2015-16 HES and may not align well to data in earlier years due to the changing nature of Household expenditure and the economic conditions prevailing at the time.
Where individual Household expenditure items do not correlate to one Input-Output product group, weights have been calculated using the best data available. Correspondences for some IOPGs have not been included due to confidentiality issues.
Data from the HES, classified by the HEC does not correlate directly to HFCE data as published in the National Accounts due to the following reasons:
- The scope of the HES excludes residents of remote areas, and those living in non-private dwellings (hotels, boarding houses and institutions);
- HFCE data includes expenditure by Non-Profit Institutions Serving Households units that are not included in HES;
- HFCE uses additional data sources including the Retail and Wholesale industry surveys;
- HES data is not used to compile HFCE data for Gambling as it collects data on a different basis;
- HES data is not used to compile Financial and insurance services as HES measures the total cost paid for insurance, and HFCE only captures the Insurance services charge;
- HES data is not used to compile the Actual rent paid on dwellings, and HFCE also includes an imputed value for rent for owner- occupied dwellings;
- HES estimates for Health include only out of pocket expenses, and do not include nursing home fees;
- For Education services, HES excludes expenditure on the Higher education loan program;
- HFCE estimates for repairs and maintenance are included in the Intermediate Usage of the Ownership of Dwellings industry and could not be concorded to HES data; and
HFCE estimates include an imputed value for the Financial Intermediation Services Indirectly Measured which is Measured differently in HES.
The IOPC(2018) table shows the 2018 IOPC code in column A with the 2018 IOPC descriptor shown in column C. Column D shows the corresponding IOPG(2015) code.
The IOIG(2015) table shows the 2015 IOIG code in column A with the 2015 IOIG descriptor shown in column B. Column C shows the corresponding ANZSIC Group code.
