Australian National Accounts: Input-Output Tables methodology

This table shows Australian production at basic prices by Input–Output Product Group (IOPG) and by Input–Output Industry Group (IOIG). A row in this table represents a product group and a column represents an industry group.

For example, the row representing the product group Agriculture, forestry and fishing support services shows that $486m of this product was produced by the Sheep, grains, beef and dairy cattle industry, $145m of this product was produced by the Other agriculture industry and so on, resulting in a total of $9,657m of this product being produced by all industries.

The column representing the industry group Other agriculture shows that $145m of Agriculture, forestry and fishing support services was produced by this industry, $99m of Meat and meat product manufacturing was produced by this industry and so on, resulting in a total of $27,277m of various products being produced by the Other agriculture industry.

This table shows intermediate use by using industries (IOIG) and final use by final use categories of products (IOPG) at basic prices with indirect allocation of imports. See the Glossary for an explanation of indirect allocation of imports.

A row in the first quadrant of this table represents a product group. A row in the third quadrant represents either a primary input, Australian production, total uses, gross value added or gross domestic product. A column in this table represents either an industry group, a final use or total use category. In a balanced table, total use equals total supply. Hence the column that represents the total use (last column in the table) is termed total supply.

For example, the row representing the product group Other agriculture shows that $2,359m of domestic plus imported Other agriculture was used by the Sheep, grains, beef and dairy cattle industry, $813m of domestic plus imported Other agriculture was used by the Other agriculture industry and so on resulting in a total of $17,188m of domestic plus imported product being used intermediately by all the industries.

In the final use categories, $8,910m of domestic plus imported Other agriculture was used by the household sector, $137m of domestic plus imported product was used from inventories and so on, resulting in a total of $11,391m of domestic plus imported Other agriculture being used in all final use categories.

In summary $17,188m of domestic plus imported Other agriculture was used intermediately by industries and $11,391m of domestic plus imported product was used by final use categories resulting in a total use of $28,579m of this product. Therefore, total supply of this product of $28,579m is reflected in the last column of this table.

This table shows intermediate use by using industries (IOIG) and final use by final use categories of imported products at basic prices. 

A row in this table represents a product group and a column represents an industry group or final use category. 

For example, the row representing the product group Other agriculture shows that $20m of imported Other agriculture was used by the Sheep, grains, beef and dairy cattle industry, $71m of imports of this product was used by the Other agriculture industry and so on, resulting in a total of $666m of this imported product being used intermediately by all the industries.

In the final use categories, $731m of imported Other agriculture was used by the household sector.

This table show flows at purchasers' prices reconciled with basic prices. Trade and transport margins, and net taxes on products are added to basic prices to derive purchasers' prices for intermediate and all final use categories, and total supply. Imports are indirectly allocated in this table.

A row in the first quadrant of this table represents a product group. A row in the third quadrant represents either a primary input, Australian production, total uses, gross value added or gross domestic product.

For example, the row representing the product group Other agriculture shows that domestic plus imported Other agriculture valued at $17,188m at basic prices was used by industries intermediately. Net taxes on products and trade and transport margins associated with this intermediate use were $62m and $4,699m respectively. Therefore, domestic plus imported Other agriculture used intermediately by all the industries was $21,949m valued at purchasers' prices.

This table shows the allocation of Australian produced industry outputs to industries and to all final use categories. This table is similar to Table 2. Unlike Table 2 however, it has industry by industry dimensions and imports are treated differently. In this table imports are directly allocated meaning they are allocated to the industries which use them and are included with the primary inputs to these industries in deriving the total production. With this method the intermediate and final use contain only the use of the domestic production and so the intermediate use matrix does not reflect the full input structure of industries. 

A row in quadrants 1 and 2 or a column in quadrants 1 and 3 of this table represents an industry group. A row in quadrants 3 and 4 represents a primary input, Australian production, value added or gross domestic product. A column in quadrants 2 and 4 represents a final use category. 

For example, the row representing the industry group Other agriculture shows that $2,411m of output from the industry Other agriculture was used by the Sheep, grains, beef and dairy cattle industry, $764m of output from this industry was used by the Other agriculture industry and so on, resulting in a total of $16,662m of output produced by the Other agriculture industry being used intermediately by all industries.

In the final use categories, $7,832m of output produced by the Other agriculture industry was used by the household sector, $2m was used by the government sector and so on, resulting in a total of $10,615m of output from the Other agriculture industry being used by all final use categories. 

This table shows values in a particular column representing the direct input requirements from each industry (Australian production) and from all primary inputs when Australian output of the industry or final use category, represented by the column, increases by $100.

A row in quadrants 1 and 2, or a column in quadrants 1 and 3 of this table represents an industry group. A row in quadrants 3 and 4 represents a primary input or Australian production. A column in quadrants 2 and 4 represents a final use category. 

For example, the column representing the industry Other agriculture shows that this industry requires $1.25 of output from the Sheep, grains, dairy and beef cattle industry, $0.55 of output from the Poultry and other livestock industry and so on, resulting in total requirements of $43.42 output from all industries, $10.22 of compensation of employees, $40.46 of gross operating surplus & mixed income and so on to produce $100 of output.

This table shows values in a particular column representing the total input requirements of Australian production from each industry represented by a row, by the industry represented by that column when the Australian output of the industry increases by $100.

A row or column in this table represents an industry group. 

The values in Table 6 represent the direct requirements coefficients for each industry when its output is increased by $100. When an industry increases its output, apart from the direct requirements from the industries, there are also indirect requirements from the industries. The values in Table 7 represent the total requirements (i.e. initial + direct + indirect requirements) from all the industries when each industry's output is increased by $100. Another important difference between Tables 6 and 7 is that Table 7 is a square matrix whereas Table 6 is not. Because the initial effect is $100 for each industry, the total requirements coefficients in the top left to bottom right diagonal of this square table will be greater than or equal to 100.

For example the column representing the industry Other agriculture shows that the total requirements by this industry from the Sheep, grains, beef and dairy cattle industry is $1.72 of output, $0.65 of output is required from the Poultry and other livestock industry and so on to increase its output by $100.

This table is similar to Table 5. Unlike Table 5 however, it describes the allocation of products, inclusive of imports, but excluding re–exports, from industry to industry and to all final use categories. That is, in Table 5, imports are directly allocated to the industries which use them and are included with the primary inputs to these industries deriving the total production. In this table imports are indirectly allocated and are included in the intermediate use of industries and in final use categories without distinguishing the imports from the products with which they compete, allowing the intermediate use matrix to fully reflect the input structures of industries. The imports in this table are indirectly allocated based on the industry to which the import is primary and the re-exports are included with the exports.

A row in quadrants 1 and 2, or a column in quadrants 1 and 3 of this table represents an industry group. A row in quadrants 3 and 4 represents a primary input or Australian production. A column in quadrants 2 and 4 represents a final use category.

For example, the row representing the industry group Other agriculture shows that $2,431m of output from the industry Other agriculture was used by the Sheep, grains, beef and dairy cattle industry, $835m of output from this industry was used by the Other agriculture industry and so on, resulting in a total of $17,328m of output produced by the Other agriculture industry being used by all industries intermediately.

In the final use categories, $8,563m of output produced by the Other agriculture industry was used by the household sector, $2m was used by the government sector and so on, resulting in a total of $11,346m of output from the Other agriculture industry being used by all final use categories.

This table is similar to Table 6. However, the values in this table factor in imports, whereas the values in Table 6 do not. The values in a particular column of this table represent the direct requirements of supply from the industry represented by the row, when the Australian output of the industry represented by the column increases by $100.

A row in quadrants 1 and 2, or a column in quadrants 1 and 3 of this table represents an industry group. A row in quadrants 3 and 4 represents a primary input or Australian production. A column in quadrants 2 and 4 represents a final use category. 

For example, the column representing the industry Other agriculture shows that this industry directly requires $1.26 of supply from the Sheep, grains, beef and dairy cattle industry, $0.55 of supply from the Poultry and other livestock industry and so on, resulting in the requirements of a total supply of $47.61 to produce $100 of output. 

To produce $100 of output the Other agriculture industry directly requires $10.22 of compensation of employees, $40.46 of gross operating surplus & mixed income and so on.

This table is similar to Table 7. However, the values in this table factor in imports whereas the values in Table 7 do not. The values in a particular column of this table represent the total supply requirements from the industry represented by the row, when the Australian output of the industry represented by the column increases by $100.

A row or column in this table represents an industry group. 

The values in Table 9 represent the direct requirement coefficients for each industry when its output is increased by $100. When an industry increases its output, apart from the direct requirements from the industries, there are also indirect requirements from the industries. The values in Table 10 represent the total requirements (i.e. initial + direct + indirect requirements) from all the industries when each industry's output is increased by $100. Another important difference between Tables 9 and 10 is that Table 10 is a square matrix whereas Table 9 is not. As the initial effect is $100 for each industry, the total requirement coefficients in the top left to bottom right diagonal of this square table will be greater than or equal to 100.

For example, the column representing the industry Other agriculture shows that the total requirements by this industry from the Sheep, grains, beef and dairy cattle industry is $1.91 of output and imports, $0.67 of output and imports from the Poultry and other livestock industry and so on to increase its output by $100.

This table shows values that represent the requirements of compensation of employees, gross operating surplus and mixed income, taxes less subsidies on products, other taxes less subsidies on production and imports by the industry represented by that row, when that industry uses a total of $100 of these primary inputs in the production process.

It is important to note that this takes into account the total output requirements (that is initial+direct+indirect effects) from all industries, by an industry, when this industry increases its output.

For example, $100 of total use of primary inputs by the Sheep, grains, beef and dairy cattle industry consists of $26.40 of compensation of employees, $58.63 of gross operating surplus and mixed income, $1.21 of taxes less subsidies on products, $2.79 of other taxes less subsidies on production and $10.98 of imports.

The first column in this table shows the specialisation ratios for an industry. An industry may produce a number of products, some of which may be primary to that industry and some of which may be primary to other industries. The specialisation ratio shows the proportion of an industry's output that is primary to that industry.

For example, 93.8% of the output of the Sheep, grains, beef and dairy cattle industry is attributed to the output primary to this industry, 96.1% of the output of the Other agriculture industry is attributed to the output primary to this industry and so on.

The second column in this table shows the coverage ratios for a product. A product may be supplied by more than one industry. The coverage ratio shows what proportion of the total domestic supply of a product is produced by the industry to which the product is primary.

For example, the entire Sheep, grains, beef and dairy cattle product is produced by the Sheep, grains, beef and dairy cattle industry to which the product is primary, 92.4% of Agriculture, forestry and fishing support services is produced by the Agriculture, forestry and fishing support services industry to which the product is primary and so on.

This table shows the composition of margin and non–margin commodities in the supply of relevant products. 

For example, the total Gas Supply was $4,639m, of which $3,181m was margin commodity. Of the total $121,730m supply of Wholesale Trade, $116,288m was margin commodity and $5,442m was non–margin commodity.

The 2009 IOIG codes are in column C with the 2009 IOIG descriptors shown in column E. Column D indicates whether a 2005 IOIG is mapped partially to a 2009 IOIG and is indicated by a 'p' in the column.

For example, the 2005 IOIG 0102 (Grains) is mapped partially to the 2009 IOIG's 0101 (Sheep, grains, beef and dairy cattle) and 0103 (Other agriculture).

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).

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.

The IOPC(2017) to IOPC(2018) table shows the 2017 IOPC code in column A with the 2017 IOPC descriptor shown in column B. Column C shows the 2018 IOPC code with the 2018 IOPC descriptor in column D. Most of the changes between IOPC(2017) and IOPC(2018) are minor corrections to the IOPC descriptors to improve their coherence.

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.

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 service 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;

Australian production refers to the value at basic prices of goods and services produced in Australia.

The basic price is the amount receivable by the producer from the purchaser for a unit of a good or service produced as output minus any tax payable, and plus any subsidy receivable, on that unit as a consequence of its production or sale. It excludes any transport charges invoiced separately by the producer. Output sold at prices that are not economically significant (see also Economically significant prices) is not valued at these prices. Rather, such output is valued at its cost of production.

Changes in inventories represent the difference in value between inventories held at the beginning and end of the reference period by enterprises and general government. For national accounting purposes, physical changes in inventories should be valued at the prices current at the times when the changes occur. For these purposes, changes in inventories are obtained after adjusting the increase in book value of inventories by the inventory valuation adjustment. The need for the latter arises because the changes in the value of inventories as calculated from existing business accounting records do not meet national accounting requirements. The inventory valuation adjustment is the difference between the change in (book) value of inventories and the physical changes valued at current prices. The physical changes at average current quarter prices are calculated by applying average quarterly price indexes to the changes in various categories of inventories in volume terms.

Compensation of employees is the total remuneration, in cash or in kind, payable by an enterprise to an employee in return for work done by the employee during the accounting period. It is further classified into two sub-components: wages and salaries; and employers’ social contributions. Compensation of employees is not payable in respect of unpaid work undertaken voluntarily, including the work done by members of a household within an unincorporated enterprise owned by the same household. Compensation of employees excludes any taxes payable by the employer on the wage and salary bill (e.g. payroll tax).

Competing imports are those products which are both produced domestically and imported, so that substitution between the two sources of supply is possible.

A product may be produced by more than one industry. The coverage ration shows what proportion of the total domestic supply of a product is produced by the industry to which the product is primary.

The direct allocation method of recording imports involves allocating imports to the industries which use them and including them with the primary inputs to these industries in deriving the total production. With this method the intermediate consumption and final demand matrices contain only the use of domestic production, and so the intermediate use matrix does not reflect the full input structure of industries.

Direct requirement coefficients refer to the proportion of inputs directly required from industries by industries to produce $100 of output. In calculating the direct requirements coefficients, the flow on effects on industries are not taken into account.

The GST is a tax of 10 per cent on the price of most goods and services in Australia, including those that are imported. It does not apply to sales of goods or services that are either exempt (GST-free) or input-taxed.

Net expenditure on goods and services by public authorities, other than those classified as public corporations, which does not result in the creation of fixed assets or inventories or in the acquisition of land and existing buildings or second-hand assets. It comprises expenditure on compensation of employees (other than those charged to capital works, etc.), goods and services (other than fixed assets and inventories) and consumption of fixed capital. Expenditure on repair and maintenance of roads is included. Fees, etc., charged by general government bodies for goods sold and services rendered are offset against purchases. Net expenditure overseas by general government bodies and purchases from public corporations are included. Expenditure on defence assets is classified as gross fixed capital formation.

Gross domestic product is the total market value of goods and services produced in Australia within a given period after deducting the cost of goods and services used up in the process of production, but before deducting allowances for the consumption of fixed capital. Thus gross domestic product, as here defined, is 'at market prices'. It is equivalent to gross national expenditure plus exports of goods and services less imports of goods and services.

Expenditure on new fixed assets plus net expenditure on second-hand fixed assets and including both additions and replacements.

Gross mixed income of unincorporated enterprises is the term reserved for the surplus accruing to owners of unincorporated enterprises from processes of production (as defined for gross operating surplus) before deducting any explicit or implicit interest, rents or other property incomes payable on the financial assets, non-produced non-financial natural resource assets (such as land) required to carry on the production and before deducting consumption of fixed capital. However, GMI is measured after the deduction of FISIM and the insurance service charge. The owners, or other members of their households, may work without receiving any wage or salary. Mixed income therefore includes both gross operating surplus for unincorporated enterprises and returns for the proprietors' own labour (akin to wages and salaries). In practice, all unincorporated enterprises owned by households that are not quasi-corporations are deemed to fall into this category, except owner-occupiers in their capacity as producers of housing services for own final consumption, and households employing paid domestic staff (an activity which is deemed to generate zero surplus).

Gross operating surplus is a measure of the surplus accruing to owners from processes of production before deducting any explicit or implicit interest charges, rents or other property incomes payable on the financial assets, non-produced non-financial natural resource assets (such as land) required to carry on the production and before deducting consumption of fixed capital. However, GOS is measured after the deduction of FISIM and the insurance service charge. It excludes gross mixed income which is the surplus accruing to owners of unincorporated enterprises. Gross operating surplus is also calculated for general government, where it equals general government's consumption of fixed capital.

Gross value added is defined as the value of output at basic prices minus the value of intermediate consumption at purchasers' prices. The term is used to describe gross product by industry and by sector. Basic prices valuation of output removes the distortion caused by variations in the incidence of commodity taxes and subsidies across the output of individual industries.

Net expenditure on goods and services by persons and expenditure of a current nature by private non-profit institutions serving households. This item excludes expenditures by unincorporated businesses and expenditures on assets by non-profit institutions (included in gross fixed capital formation). Also excluded are maintenance of dwellings (treated as intermediate expenses of private enterprises), but personal expenditure on motor vehicles and other durable goods and the imputed rent of owner-occupied dwellings are included. The value of 'backyard' production (including food produced and consumed on farms) is included in household final consumption expenditure and the payment of wages and salaries in kind (e.g. food and lodging supplied free to employees) is counted in both household income and household final consumption expenditure.

The indirect allocation method of recording imports includes those imports in the intermediate use of industries and in the final use categories without distinguishing the imports from the products with which they compete. This allows the intermediate use matrix to fully reflect the input structures of industries. With this method the imports are also listed under the industries’ use of primary inputs, but after deriving total production.

The chain of calculations of output requirements can be continued beyond the direct requirements of an industry. For example, in order to produce output from the chemicals industry, inputs are required directly from the mining industry. To produce this direct requirement of the mining industry, the chemical industry needs, in turn, additional output from the mining industry, and so on in a convergent infinite series. The example has been confined to two industries directly dependent on each other, but indirect requirements can arise even in the absence of direct dependence. For example, the mining industry may not directly require any inputs from agriculture, but it requires inputs from chemicals which cannot be satisfied without input from agriculture. Therefore, there is an indirect requirement by mining for agricultural input.

IOIGs are based on the Australian and New Zealand Standard Industrial Classification (ANZSIC) and the I-O tables are published at this level of industry.

The IOPC is the detailed level product classification, organised according to the industry to which each product is primary. I-O tables are compiled at this level of product classification.

IOPGs are groups of IOPCs aggregated to the IOIGs to which they are primary. I-O tables are published at this level of product classification.

Intermediate consumption consists of the value of the goods and services consumed as inputs by a process of production, excluding the consumption of fixed capital.

Intra-industry flows refer to the production by units in an industry and use of that production by other units within the same industry. Australian I-O tables include the values of these flows.

Inventories consist of stocks of outputs that are held at the end of a period by the units that produced them prior to their being further processed, sold, delivered to other units or used in other ways, and stocks of products acquired from other units that are intended to be used for intermediate consumption or for resale without further processing.

If the transactions are valued at basic prices, the margins are recorded as intermediate consumption (e.g. transport, wholesale trade) of the intermediate users or final buyers. If transactions are valued at purchasers’ prices the value of margins in included, along with taxes less subsidies on products with the purchasers’ price of the good to which the margin relates.

Other subsidies on production consist of all subsidies, except subsidies on products, which resident enterprises may receive as a consequence of engaging in production. Other subsidies on production include: subsidies related to the payroll or workforce numbers (including subsidies payable on the total wage or salary bill), on numbers employed, or on the employment of particular types of persons, e.g. persons with disabilities or persons who have been unemployed for a long period.

Other taxes on production consist of all taxes that enterprises incur as a result of engaging in production, except taxes on products. Other taxes on production include: taxes related to the payroll or workforce numbers excluding compulsory social security contributions paid by employers and any taxes paid by the employees themselves out of their wages or salaries; recurrent taxes on land, buildings or other structures; some business and professional licences where no service is provided by the Government in return; taxes on the use of fixed assets or other activities; stamp duties; taxes on pollution; and taxes on international transactions

The primary input content per $100 of use by an industry shows the ultimate content (resulting from total requirements) of each primary input in $100 of that industry’s use.

Primary inputs include compensation of employees, gross operating surplus and gross mixed income, taxes less subsidies on products, other taxes less subsidies on production and imports.

The purchaser's price is the amount paid by the purchaser, excluding any deductible tax, in order to take delivery of a unit of a good or service at the time and place required by the purchaser. The purchaser’s price of a good includes any transport charges paid separately by the purchaser to take delivery at the required time and place.

The following link Input output table diagram contains a simplified input–output table for illustration purposes. In this illustration, Quadrant 1 represents the industry (row) by industry (column) dimension, quadrant 2 represents the industry by final demand dimension, quadrant 3 represents primary input by industry dimension and quadrant 4 represents the primary input by final demand dimension.

• Quadrant 1
  Flows between domestic industries are shown in Quadrant 1. This is usually referred to as the inter–industry quadrant. Each column in this quadrant shows the intermediate inputs into an industry in the form of goods and services produced by other industries, and each row shows those parts of an industry's output which have been absorbed by other industries. For example, the cell at the intersection of row i and column j shows how much output of industry i has been absorbed by industry j for current production.
• Quadrant 2
  Disposition of output to categories of final demand is shown in Quadrant 2. Quadrants 1 and 2 together show the total usage of the goods and services supplied by each industry.
• Quadrant 3
  Quadrant 3 shows entries usually referred to as primary inputs: compensation of employees; gross operating surplus and gross mixed income; imports; and various types of taxes on production.
• Quadrant 4
  Quadrant 4 shows primary inputs to final demand. In the Australian Input Output Tables, only the primary input 'Taxes less subsidies on products' has values in this quadrant.
   

Re-exports are goods imported into Australia and then exported without having been used or transformed in any way.

An industry may produce a number of products, some of which may be primary to that industry and some of which may be primary to other industries. The specialisation ratio shows the proportion of an industry’s output that is primary to that industry.

A subsidy on a product is a subsidy payable per unit of a good or service. The subsidy may be a specific amount of money per unit of quantity of a good or service, or it may be calculated ad valorem as a specified percentage of the price per unit. A subsidy may also be calculated as the difference between a specified target price and the market price actually paid by a purchaser. A subsidy on a product usually becomes payable when the product is produced, sold or imported, but it may also become payable in other circumstances, such as when a product is exported, leased, transferred, delivered or used for own consumption or own capital formation.

A tax on a product is a tax that is payable per unit of some good or service. The tax may be a specific amount of money per unit of quantity of a good or service (quantity being measured either in terms of discrete units or continuous physical variables such as volume, weight, strength, distance, time, etc.), or it may be calculated ad valorem as a specified percentage of the price per unit or value of the goods or services transacted. A tax on a product usually becomes payable when it is produced, sold or imported, but it may also become payable in other circumstances, such as when a good is exported, leased, transferred, delivered, or used for own consumption or own capital formation.

A total requirement coefficient at the intersection of a row i and column j of a table represents the value of output of industry i required directly and indirectly to produce 100 units of output absorbed by final demand (i.e. final output) of industry j.

Trade margin is defined as the difference between the actual or imputed price realised on a good purchased for resale and the price that would have to be paid by the distributor to replace the good at the time it is sold or otherwise disposed of.

Transport margins include any transport charges invoiced separately. The costs arising through the transport of goods from a producer to a purchaser by a third party even without separate invoice is excluded from the basic price of the good being transported and is recorded as a transport margin. The latter treatment is adopted for the I-O tables only and is a deviation from the treatment outlined in the 2008 SNA and applied in the ABS S-U tables.
