Overview

This release of Data by region presents various data for 2011-2022, including the Census of Population and Housing (Census) data for 2011, 2016 and 2021. Data by Region is a visual compendium of regional data, enabling users to find data for over 4,500 regions across Australia.  It contains over 800 data items, covering a range of themes including Population, Economy and Industry, Income, Education, Employment and Land and Environment.

To access the Data by region map interface, refer to Data by region. This interface enables users to search and explore data for regions across Australia.

Geographical Coverage

Data is available for:

  • Australia
  • States and Territories
  • Greater Capital City Statistical Areas
  • Statistical Areas 2, 3 and 4
  • Indigenous Locations, Indigenous Areas, and Indigenous Regions
  • Remoteness Areas
  • Local Government Areas

This issue of Data by region presents data on ASGS Edition 3 (2021) for Main Structure, Greater Capital City Statistical Areas (GCCSA), Indigenous Structure and Local Government Areas (LGAs). The LGA data available in this product are based on 2021 Local Government Area boundaries. Remoteness Areas remain on ASGS Edition 2 (2016). For more information see; 

For more information, see the Statistical Geography page of the ABS website.

Data for 'Other Territories' has been included for some but not all of the data sets included in Data by region, dependent on its availability in the source datasets. In some cases Other Territories contribute to the totals for States and Australia but are not presented separately (due to availability). For this reason, summing data at lower geographic levels to State or Australia totals may result in figures that don't align to the published values.

Source

Data is sourced from a wide variety of collections, both ABS and non-ABS. When analysing these statistics, care needs to be taken as time periods, definitions, methodologies, scope, and coverage can differ across collections.

Collection method

Data presented in this product are sourced from administrative datasets, the Census of Population and Housing, and various ABS surveys.

Income data comparisons

Care should be taken in comparing income data from different sources. Some of the differences between the personal income data sourced from the Australian Taxation Office (ATO) and income data sourced from the Census of Population and Housing are highlighted in the table below:

 
DifferencePersonal Income (ATO)Census of Population and Housing
PopulationIndividuals with income reported to the ATO (approximately 13 million records per year), either through a personal income tax form, or through a PAYG statement.All persons aged 15 years and above (approximately 20 million records).
Method of reportingReporting in a personal income tax return, often with a group certificate or other supporting evidence of income, where required by ATO. Reporting is in more detail, showing different sources, and dollar values.Self reported income is reported in ranges on a Census form.
Missing incomeSome income is not reported to the ATO. People who earn less than the tax free threshold or receive payments that are not assessable (such as some Government benefits and allowances) may not report to the ATO.No missing income - the Census form asks people to include all income when answering income questions.

Updated data series

Care should be taken in comparing data within previous and current releases of Data by region as:

  • some data have been revised
  • releases prior to November 2022 may use earlier editions of the Australian Statistical Geography Standard (ASGS)

June 2023 updates are summarised in the table below.

Accuracy

For further information on the accuracy of data items see Concepts, sources and methods.

Geographical correspondences

The use of geographical correspondences enables data to be converted from one type of geographical region to another. Correspondences are usually provided as conversion factors based on relative population distributions and/or land area shares.

The application of correspondences allows:

  • the source data to be more easily compared with standard ABS output
  • the source data to be output for other geographical areas such as Statistical Areas 2-4 and Local Government Areas (LGA)
  • extra flexibility, where data can be provided for a variety of geographies of interest to the data user

Geographic correspondences have some limitations. In applying the correspondences it is assumed that the particular characteristics of any data item are uniformly distributed across the region. Therefore, data produced by correspondences may not truly reflect the distribution of the characteristics of the population.

Some official postcodes (such as Post Office boxes) do not correspond to residential areas but may still have been reported under the current home address field in certain administrative data series. Data for these and other 'invalid' postcodes - such as those due to incorrect reporting or processing errors - are included in state and territory totals or for Australia where the state or territory was not known.

In addition to these limitations please note that the figures produced by correspondences have been rounded. Therefore, there may be small differences between the sum of the component items and the totals shown.

While care was taken in producing the correspondences the ABS cannot guarantee the accuracy of data produced by correspondences. ASGS correspondences can be found via the Correspondences page of the ABS website.

How the data is released

Data by region can be accessed as:

  • data cubes, presented in a time series spreadsheet format for each themed category as listed below, see data downloads
  • interactive map, where the interface enables users to search for and explore data within regions across Australia, refer to Data by region
  • Data Explorer, where users are able to create customised data tables

Data can be found across the following categories:

  • Population and people
  • Aboriginal and Torres Strait Islander Peoples
  • Economy and industry
  • Income (including government allowances)
  • Education and employment
  • Health and disability
  • Family and community
  • Persons born overseas
  • Land and environment

Not all data items are available for each geography level. For data items where data is either not available, not available for publication, nil, rounded to zero, or a null cell for a particular region, the data item may not be displayed in the interactive map.

Confidentialisation of data

Some data values have been randomly adjusted or suppressed to avoid the release of confidential data. In some cases small cells have been randomly adjusted to zero. Care should be taken when interpreting cells with small numbers or zeros.

Census table cells are adjusted to prevent any identifiable information about individuals being released. This technique is called perturbation and is applied to all table cells including totals. These adjustments result in small introduced random errors and can mean that the rows and columns of a table do not sum to the displayed totals, however, the value of the table as a whole is not significantly affected. We do not recommend users attempt to calculate populations by aggregating rows or columns containing subcategories of a population, but instead use the published total counts.  

While the adjustments due to perturbation are only small, they do show a greater relative impact on small counts. These small counts should be used with caution and no reliance should be placed on the counts or the related percentages, which can be greater than 100. 

For further information refer to Census methodology, Introduced random error / perturbation
