Compelling Economics, REMPLAN industry data
-
REMPLAN economic modeling and analysis system.
economy.id® industry sector profiles use an input-output model developed by REMPLAN.
An input-output model depicts the inter-industry relations of an economy. It shows how the output of one industry is an input to each other industry. Using a matrix representation of an area’s economy, a given input is typically enumerated in the column of an industry and its outputs are enumerated in its corresponding row. This format, , shows how dependent each industry is on all others in the economy both as customer of their outputs and as supplier of their inputs.
Input-output models are an important economic development tool used to:
- Depict the structure of economies;
- Predict the effect of changes in one industry on others and by consumers, government, and foreign suppliers on the economy;
- Measure the economic impacts of events, public investments or programs;
- Identify economically related industry clusters; and
- Identify "key" or "target" industries whose development are most likely to enhance the internal coherence of an specified economy
A more detailed explanation can be found at en.wikipedia.org/wiki/Input-output_analysis.
REMPLAN's input-output model provides local economic data where it is not available from a primary source by employing a 'top down' approach to convert National Accounts tables into a model for the local area. The model uses ABS Census employment by industry sector data, which is available at the local level, as the basis for disaggregating the National Accounts data by making assumptions about the level of productivity per job in each industry sector. Assuming regional productivity matches national average performance, the productivity figures are applied to the number of workers in each industry in the local area to measure the relative contribution of each sector to a local economy. Additional processes to derive local area data include adjustment for local prices as well as local imports and exports (including interregional trade).
It is important the underlying assumptions of 'top down' modeling are kept clearly in mind when using this data.
- it is assumed that local productivity matches national average performance. Therefore these models are appropriate for presenting a snapshot of the local economy, but are not designed for undertaking economic forecasts;
- it is assumed that input proportions will remain the same for the life of the National Accounts data (that is, 2 to 3 years between update and publication of the National Accounts tables) and there will be no significant changes in efficiencies per employed person over that period. Efficiency levels are driven by factors such as technological innovation, in a given industry sector. id updates the revised REMPLAN economic data when it becomes available immediately after the publication of the National Accounts data.
The selected REMPLAN data presented in economy.id® presents a snapshot of the status quo of the local economy and the interrelationships between industry sectors. It provides the context for understanding the local economy and some insights upon which to develop strategies for economic development. The user should note that the full REMPLAN model has significant additional benefits that include: assessing the economic impacts of change; gap analysis; and testing the impact of different economic scenarios for a local area.

Australian Bureau of Statistics Census data
-
The Census of Population and Housing is undertaken by the Australian Bureau of Statistics every five years and provides a snapshot of the nation, which helps define who we are and what we do.
The Census is one of the most comprehensive sources of economic data available to local government because it:
- includes a series of questions about skills and employment, including education levels, occupations, industry of employment, hours worked, method of travel to work and income;
- provides that information for small geographic areas, including Local Government Areas; and
- links where people live with where they work.
In economy.id® Census data is used to present the economic base of the local area, as well as to present the characteristics of the Workforce, Residents, Local Labour Force and Regional Labour Force. Census employment data is also the base data used to convert National Accounts data into an input-output model for a local area in the REMPLAN model.
economy.id® includes data from the 2001 and 2006 Census to show how the local economic base and population characteristics are changing. The 2006 Census was conducted on 8 August 2006. The next Census will be conducted on 9 August, 2011.

Australian Bureau of Statistics Place of work data
-
Place of Work data provides information on where people work. It is based on the Census Question: "For the main job held last week, what was the person's workplace address?"
Place of Work data is coded to Destination Zones, which are designed by State Transport Authorities (STAs) in each state and territory. Work Destination Zones concord with Local Government Area boundaries, but they do not match other Census boundaries such as collection districts. They are designed to reflect the location of industry rather than residents, so there are more, small destination zones around major employment nodes, while they are large and sparser in residential and rural areas.
In economy.id® Place of Work Data is used to identify the employment locations of people working in each industry sector in the local area. The data is presented in thematic maps by destination zone for each industry sector.

Australian Bureau of Statistics Journey to work data
-
Understanding the relationship between where people live and where they work is important for understanding what labour resources an economy draws upon. Journey to Work data is created by cross tabulating a person's main workplace address (Place of Work Data) with their place of usual residence to create a matrix of home to work.
In economy.id® Journey to Work data is used to answer the following questions:
- Where do the workers come from? This provides the basis for determining the region from which the local area draws its labour resources.
- Where do our residents work? This provides the basis for understanding the level of employment self-containment in a local area. Self containment is expressed as the proportion of people who work locally that reside locally.
The data is available by industry to enable these questions to be answered for each industry sector in the economy. The data is presented at the LGA level. This information is generally not available at the small area (suburb / locality) level due to geographic limitations when being coded or processed.

Australian Bureau of Statistics Business Register
-
The ABS Business Register is extracted from the Australian Business Register maintained by the ATO. It is a count of businesses with an Australian Business Number (ABN) on the Australian Business Register that are actively registered for GST (i.e. actively trading).
The ABS Business Register does not include:
- entities without an ABN - mainly individuals whose business activities fall under the threshold for GST compliance and whose taxation obligations can be satisfied under the Personal Income Tax System
- ABNs without a GST role – mainly businesses with turnover <$50,000pa, not-for-profit institutions with turnover of <$100,000 or entities whose activities does not involve trading in goods or services (eg investment vehicles)
- Businesses that have ceased trading - no longer actively remitting GST obligations
- Establishment of new locations associated with an existing business
- Entities not considered to be actively trading in the market sector, including:
- Central Bank
- General Government – this particularly affects data for Education and Health and Community Services and means that institutions such as public universities, public schools, public hospitals and other public education and health organisations are not included in this data.
- Non-Profit Institutions Serving Households
- Charitable Institution
- Social and Sporting Clubs
- Trade Unions and Other Associations
- Other Unincorporated Entity
- Diplomatic or Trade Missions, Other Foreign Government
- Private Households Employing Staff
The ABS Business Register does include:
- employing and non-employing businesses
- Single location and multiple location businesses
- Entities with complex business structure - the business is assessed and broken up into Type of Activity Units (TAUs). The statistical unit referred to as a "business" thus consists of ABNs and TAUs
Detailed information about this data set, including summary findings from the national dataset by industry sector, can be found on the ABS website.
The ABS Business Register is published annually and economy.id® incorporates the latest release of this data which is a snapshot as at 1 June 2007. It presents the number of businesses in each industry sector in the local area by turnover and number of employees. This data should not be used in time series due to changes in scope and methodology.
