Australian Built Environment: Output and Employment

Industries are groups of firms with common characteristics in products, services, production processes and logistics, subdivided by the SIC into a four-level structure. The highest level is alphabetically coded divisions such as Agriculture, forestry and fishing (A), Manufacturing (C) and Information and communication (J). The classification is then organized into two-digit subdivisions, three-digit groups, and four-digit classes. SIC codes are therefore two, three and four-digit numbers representing industries, defined as firms with shared characteristics.


The SIC definition of the construction industry captures the onsite activities of contractors and subcontractors, and this data on building and construction work is taken to represent the industry. However, onsite work brings together suppliers of services, materials, machinery and equipment, products, components and other inputs required to deliver the buildings and structures that make up the built environment. When enough firms share sufficient characteristics they are often described as an industry cluster or sector.


The data used here is provided in the Australian Bureau of Statistics annual publication Australian Industry (ABS 8155), produced using a combination of data from the annual Economic Activity Survey and Business Activity Statement data provided by the Australian Taxation Office. The data includes all operating business entities and Government owned or controlled Public Non-Financial Corporations. Australian Industry excludes the finance industry and public sectors, but includes non-profits in industries like health and education and government businesses providing water, sewerage and drainage services.[1] The industries included account for around two-thirds of GDP and the data is presented at varying levels for industry divisions, subdivisions and classes. The most recent issue is for 2020-21.


There is data at the two digit subdivision level for the Construction services and Property operators and real estate services industries. For the subdivisions in Professional, scientific and technical services and Building cleaning, pest control and other services the data includes contributions from other classes outside the built environment. Therefore, for these industries the two digit subdivision estimates have to be weighted using the four digit class data for the built environment component. These proportions are released as supplementary tables and provide data at the class level. Professional, scientific and technical services were included in 2015-16, and in 2016-17 this data was provided for two divisions: Rental, hiring and real estate services, with subdivisions Rental and hiring services (except real estate), and Property operators and real estate services; and Administrative and support services, with subdivisions Administrative services and Building cleaning, pest control and other support services.


The data is not complete because some industries cannot be separated into the relevant classes from Australian Industry. For example, rental of heavy machinery and scaffolding (class 6631) is in subdivision 66 but the data is not available to separate it from the other classes. Also, services such as marketing, legal, insurance and financial are important inputs, but again are not identifiable. Government spending on infrastructure and investment in departments like health and education is included through supply industries, although any maintenance and work done internally will generally not be included. That also applies in industries like retailing and transport where some unknown proportion of work is done in-house.


There is also leakage around the boundaries of industry statistics: some glass is used in mirrors, some in car windscreens; textiles are used in buildings; architects design furniture; engineers repair machines as well as structures, and so on. Because Australian Industry uses tax and business register data, it is the self-classification of firms to SIC industry classes that fundamentally determines the structure and scope of that data. Needless to say, such classifications are not perfect, particularly in regard to large multi-unit or multi-divisional organisations. The data here includes sixteen industries that together form one of the largest and most important industrial sectors in the economy.

The IVA of the sixteen built environment industries contributed 13.6 percent to Australian GDP in 2018-19, within a long-run range between 13 and 15 percent of GDP since 2006-07. The sixteen built environment industries share of total employment was 16.9 percent, and its long-run range was between 16.5 and 17.5 percent of total employment.

About the Blog

This blog is concerned with the organisation of the building and construction industry, in the economic sense of combining factors of production to create output.

 

The modern industry's origins in the 19th century can still be seen in many of its characteristic features, and many contemporary issues are also found in projects from the past.

 

Like many industries, it is being reshaped by unprecedented rapid and widespread advances in materials, technology and capability.
