Data by region methodology

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:

Agricultural commodities data are estimates obtained from the 2011 and 2016 Agricultural Census. The scope of the 2016 Agricultural Census was all businesses undertaking agricultural activity recorded on the ABS Business Register above a minimum size cut off of $40,000. For the 2011 Agricultural Census, the cut-off was $5,000; 2011 data in Data by region was re-derived using the $40,000 threshold. The measure of size was based on the ABS' Estimated Value of Agricultural Operations or, if this was not available, a derived value based on Business Activity Statement turnover.

Since not all of the businesses that were selected provided data, there are estimated data components. The estimates are subject to sampling variability; that is, they may differ from the figures that would have been produced if all businesses had provided data. One measure of the likely difference is given by the standard error which indicates the extent to which an estimate might vary by chance because only a sample was taken or had responded. There are about two chances in three that a 'sample' estimate will differ by less than one standard error from the figure that would have been obtained if all businesses had responded, and about nineteen chances in twenty that the difference will be less than two standard error. In agricultural data, sampling variability of the estimates is measured by the relative standard error (RSE) which is obtained by expressing the standard error as a percentage of the estimate to which it refers. In Data by region, agriculture data with an RSE greater than 50% are not presented.

For further information see Agricultural Commodities, Australia.

Data is sourced from the Births, Australia and Deaths, Australia publications.

Data for building approvals are compiled from:

• permits issued by local government authorities and other principal certifying authorities
• contracts let or day labour work authorised by Commonwealth, state, semi-government and local government authorities
• major building activity in areas not subject to normal administrative approval (e.g. building on remote mine sites)

Coverage includes:

• all residential building approvals valued at $10,000 or more
• all approved non-residential building jobs valued at $50,000 or more

For further information see Building Approvals, Australia.

See below for information on selected Census items included in this product. For information on other Census items please see the Glossary, the Census of Population and Housing home page and the Census Dictionary.

Records whether a person has Australian citizenship and was born overseas.

Commuting distance provides a measurement of the distance travelled between a person's Mesh Block of Place of Usual Residence and Mesh Block of Place of Work. An assumption in the calculation of this data is that a person has followed the shortest path with no stops when commuting to work.  Component data for Commuting to Work (i.e. distance by age and sex, and by industry) is only available at ASGS levels, and not at LGA level. LGA regions will only display whole Average and Median Commuting distance. Detailed information on how the commuting distances were calculated can be found on the Understanding the Census and Census Data page.

Structure type of private dwellings. Other dwellings include caravan, cabin or houseboat, improvised home, tent, sleepers out, and house or flat attached to a shop or office etc.

The 'modified OECD' equivalence scale is used. Equivalised total household income can be viewed as an indicator of the economic resources available to a standardised household.

Classified in terms of the relationships that exist between a single family reference person and each other member of that family. Different types of families are distinguished (in the following order of preference) based on the presence or absence of:

• couple relationships
• parent-child relationships
• child dependency relationships or other blood relationships

The family type is derived from people enumerated in the household who usually reside there and who share a familial relationship. Partners and dependent children usually present but temporarily absent are also included in this derivation. Boarders and other non-family members are excluded.

Describes the field of study of a person's highest completed non-school qualification for persons aged 15 years and over who stated that they had completed a qualification.

Highest level of primary or secondary schooling completed for people aged 15 years and over. Data is coded using the Australian Standard Classification of Education (ASCED), 2001.

Population rates are presented as a rate per 10,000 of the total population. That is, the number of homeless persons per 10,000 persons based on their place of enumeration in the Census, excluding people at sea or in migratory or offshore regions and overseas visitors. Caution should be taken when interpreting data for smaller regions (i.e. regions with fewer than 10,000 persons). The homelessness rate includes persons:

• living in improvised dwellings, tents or sleeping out
• in supported accommodation for the homeless
• staying temporarily with other households
• living in boarding houses
• in other temporary lodgings
• living in 'severely' crowded dwellings

Further details can be found in the publication Census of Population and Housing: Estimating Homelessness (cat no. 2049.0).

The IHAD summarises information about the economic and social conditions of people within households, including both relative advantage and disadvantage measures. IHAD complements the area level Socio-Economic Indexes for Areas (SEIFA) rankings by allowing the relationship between area level disadvantage and household level disadvantage to be explored. The index is based on information from the 2016 Census of Population and Housing. IHAD data has been presented as quartiles (four groups). Households are ordered from the lowest to the highest index value, with the lowest 25% of households assigned to quartile 1, the next lowest 25% of households to quartile 2 and so on, up to the highest 25% of households which are given a quartile number of 4. This means that households are divided into four equal sized groups, with quartile 1 representing the most disadvantaged households and quartile 4 representing the most advantaged households. In practice these groups won’t each contain exactly 25% of households as it depends on the distribution of the IHAD scores. Note that the groups will have an approximately equal number of households, not an approximately equal number of persons. For further information see Experimental Index of Household Advantage and Disadvantage.

Applicable to all employed people aged 15 years and over. Industry is coded using the Australian and New Zealand Standard Industrial Classification (ANZSIC), 2006. The industry code assigned is based on the main job held during the week prior to Census night.

Two occupation questions are used in the Census. The first of these asks for occupation title, while the second asks for the main tasks usually performed by the person in their occupation. Collecting both occupation title and task information ensures more accurate coding of occupations for employed people aged 15 years and over. Occupations are coded using the Australian and New Zealand Standard Classification of Occupations (ANZSCO). The Occupation code assigned is based on the main job held during the week prior to Census Night.

Describes the level of a person's highest completed non-school qualification (e.g. bachelor degree, diploma) for persons aged 15 years and over. The full classification for levels of education and fields of study, together with an explanation of the conceptual basis of the classification, can be found in the publication Australian Standard Classification of Education (ASCED), 2001.

Applicable to persons aged 15 years and over.

Country of birth is the basis for determining if a person was born overseas. The Standard Australian Classification of Countries (SACC) was used to classify responses for birthplace of individuals. People are classified as Overseas-born on the Census of Population and Housing if it was stated:

• they were born in a country other than Australia
• they were born at sea
• their response was classified 'Inadequately described'
• their response was classified 'Not elsewhere classified.

For the 2016 Census, the definition of Australia includes the states and territories and the other territories of Christmas Island, Cocos (Keeling) Islands, Jervis Bay Territory and Norfolk Island. In 2011 and previous Censuses, Norfolk Island was not included in the definition of geographic Australia.

The Australian Standard Classification of Religious Groups (ASCRG), 2016 was used to classify responses for a person's religious affiliation. Answering this Census question is optional.

Includes site fees if the dwelling is a caravan, or manufactured home in a caravan park, or a manufactured home estate.

Applicable to persons aged 15 years and over. If registered marital status is not stated it is imputed. All persons aged 15 years and over, who are usually resident and present in the household on Census night and who are not in a couple relationship are identified as 'Not married'. 

SEIFA is an ABS product that ranks areas in Australia according to relative socio-economic advantage and disadvantage. The indexes are based on information from the five-yearly Census of Population and Housing. SEIFA 2016 consists of four indexes which are a summary of a different subset of Census variables focused on a different aspect of socio-economic advantage and disadvantage.

• The Index of Relative Socio-economic Disadvantage (IRSD).
• The Index of Relative Socio-economic Advantage and Disadvantage (IRSAD).
• The Index of Education and Occupation (IEO).
• The Index of Economic Resources (IER).

Deciles divide a distribution into ten equal groups. In the case of SEIFA, the State deciles data compares the region with all the other regions in that State or Territory. The Australian deciles data compare every region across Australia. The distribution of scores is divided into ten equal groups with the:

• lowest scoring 10% of areas are given a decile number of 1
• second-lowest 10% of areas are given a decile number of 2 and so on
• highest 10% of areas which are given a decile number of 10

For further information see Census of Population and Housing: Socio-Economic Indexes for Areas (SEIFA), Australia.

These data identify the language spoken at home for people who were born overseas, and are coded using the Australian Standard Classification of Languages (ASCL). Only one language is coded for each person.

Applicable to classifiable occupied private dwellings i.e. excludes non-classifiable households such as visitors only. 'Rented' includes rent-free, 'Owned with a mortgage' includes being purchased under shared equity scheme and 'Other tenure type' includes being occupied under a life tenure scheme.

Applicable to those born overseas who will be in Australia for more than one year. The year 2016 refers to the period from 1st January 2016 to 9th August 2016 only. The data shown exclude persons who did not state their country of birth and persons born in Australia (includes Other Territories).

Relates to persons aged 15-19 years and whether the person was working or attending a school or any other educational institution.
Data for 'Other - Fully engaged' includes:

• employed full time, type of study not stated
• study part time, employed away from work
• study part time/full time status not stated, employed away from work
• employed part time, Study part time/full time status not stated

Counts of Australian Businesses including Entries and Exits (CABEE) presents counts of actively trading businesses in the Australian economy, as at June 30 for the past five years. The data used to produce these counts are extracted from the Australian Bureau of Statistics Business Register (ABSBR). The ABSBR is populated using administrative data from ABN registrations recorded in the Australian Business Register (ABR), and business data from the Australian Tax Office (ATO). Data on the structures of large and complex businesses are also collected (profiled) by ABS.

Counts of businesses include only actively trading businesses in the Australian market sector. Actively trading businesses are:

• Type of Activity Unit (TAUs) from the profiled population.
• ABNs from the non-profiled population that are actively remitting Goods and Services Tax (GST).

Businesses are considered to be engaging in productive activity where they have a Goods and Services Tax (GST) role and are actively remitting GST through Business Activity Statements (BAS). A business may still be counted as actively trading at the end of the financial year even if it has ceased operating if the associated ABN has not been cancelled and the business has remitted GST within the last five quarters (or three years for annual remitters).

Standard institutional sector classification of Australia (SISCA) is based on the System of National Accounts 2008 (SNA08) institutional sector classification. Entities classified to the following categories of SISCA are excluded:

• 2110 Reserve Bank of Australia
• 3000 General Government
• 5000 Non-Profit Institutions Serving Households
• 6000 Rest of the World

Type of legal organisation (TOLO) indicates whether a business is part of the private or public sector, and the type of ownership structure it has. Entities classified to the following TOLO categories are excluded:

• 26 Other Unincorporated Entities
• 33 Foreign Government

Each business has been classified to a single ANZSIC 2006 industry class. The industry class allocated is the activity which provides the main source of industry value added (sales of goods and services, wages and salaries or number of employees as a proxy), which is generally based on a description provided by the business.

Entities classified to the following 4 digit ANZSIC classes are excluded:

• 6210 Central Banking
• 7711 Police Services
• 7713 Fire Protection and Other Emergency Services
• 9540 Religious Services
• 9551 Business and Professional Associations
• 9552 Labour Association Services
• 9559 Other Interest Group Services n.e.c.
• 9601 Private Households Employing Staff
• 9602 Undifferentiated Goods-Producing Activities of Private Households for Own Use
• 9603 Undifferentiated Service-Producing Activities of Private Households for Own Use

Businesses can operate in more than one geographical location and be represented by a single ABN/TAU. These are referred to as multi-location businesses. Multi-location businesses are attributed to one geographical classification to prevent double counting of businesses. The individual locations of businesses with multiple sites are not available in CABEE. The issues of geocoding multi-location businesses are more pronounced in counts at smaller geographies, as multi-location businesses will only be attributed to a single SA2/LGA. As such, it cannot be assumed that business counts at each geographical level reflect all business operations within that geography.

The data published have been confidentialised so as not to reveal the identity of any businesses. The confidentiality process randomly adjusts data in such a way that the sum of components will not always be equal to total counts.

CABEE contains snapshots of counts of actively trading businesses at regular points in time. While data presented in CABEE were produced on a broadly similar conceptual basis to data presented in previous releases, users seeking to analyse change over time should be aware that there may have been methodological, classificatory, definitional, administrative and content changes between the different releases of CABEE.

For further information see Counts of Australian Businesses, including Entries and Exits.

The disability and carers data are modelled estimates based on random effects logistic regression models fitted to data from the 2015 and 2018 Surveys of Disability, Ageing and Carers, 2016 Australian Census of Population and Housing, 2015 and 2018 Estimated Resident Population, and aggregated administrative data, such as from the Department of Social Services.

This data presents modelled count and percentage of persons living in private dwelling, with the following disability and carer characteristics:

• Persons with a disability
• Persons with a profound or severe core activity limitation
• Persons with a moderate or mild core activity limitation
• Persons who are carers
• Persons aged 15 or over who are primary carers
• Persons who are non-primary carers

These modelled estimates were originally produced as part of the ABS response to the COVID-19 pandemic in order to determine the location and size of vulnerable populations across Australia. Data has been produced for Statistical Area Level 2 regions and Local Government Areas. For further information see Disability, Ageing and Carers, Australia: Summary of findings.

Statistics on children aged 4 or 5 years who, as at 1 July in the collection year, were enrolled and attending preschool programs across Australia. Data is sourced from the National Early Childhood Education and Care Collection. The Collection is derived from administrative data provided by state and territory and Australian government departments and the Catholic Education Office of the Archdiocese of Canberra and Goulburn.

For the purposes of the collection, a preschool program is defined as a structured, play based learning program, delivered by a degree qualified teacher, aimed primarily at children in the year or two before they commence full-time schooling. This is irrespective of the type of institution that provides it or whether it is government funded or privately provided. To be considered as enrolled, the child must have attended the preschool program for at least one hour during the reference period, or be absent due to illness or extended holiday leave and expected to return. Data is presented as counts by place of usual residence of the children.

Care needs to be taken when interpreting Queensland child counts prior to 2018 as there may be some duplication of children across different provider types. This is due to the inclusion of child aggregate data from some service providers for years up to and including 2017. Where the finer regional details of enrolments are not stated or unknown, these are included in the State/Territory totals but not shown separately elsewhere.

Further information on these statistics can be found in Preschool Education, Australia and Microdata: Preschool Education, Australia.

Estimated resident population (ERP) as at 30 June in a Census year is calculated by adjusting Census counts of Australian usual residents to include Australian residents temporarily overseas and account for people missed or counted twice in the Census (based on the Post Enumeration Survey), and removing any births, deaths and migration movements that happened between 30 June and Census night. 

At the national and state levels, ERP is updated from the Census base every three months by taking the population estimate at the start of the quarter and adding the components of population change: natural increase (births minus deaths), net overseas migration and (in the case of state populations) net interstate migration.  For Statistical Areas Level 2 (SA2s) and Local Government Areas (LGAs), population estimates are updated from the Census base annually as at 30 June, by taking the estimate at the start of the financial year and adding natural increase and net overseas and internal (moves between and within the states) migration. The components for these sub-state areas are calculated by breaking down state-level component estimates, ensuring consistency between the state and sub-state population and component data.

For further information see Regional Population.

The value of agricultural production estimates are derived by the multiplication of price and quantity of individual agricultural commodities. Remaining commodity data (livestock disposals and livestock products excluding eggs) are obtained from other ABS collections with some information from non-ABS sources.

Price information refers to the average unit value of a given commodity realised in the market place. More specifically, price information for livestock slaughtering and wool is obtained from ABS collections. Price information for other commodities is obtained from non-ABS sources, including marketing authorities and industry sources.

The estimates of gross value are subject to sampling error. (See above for a discussion of sampling error in Agriculture data). In Data by region, agriculture data with a relative standard error (RSE) greater than 50% are not presented.

Further information on value of agricultural production can be obtained in the ABS publication Value of Agricultural Commodities Produced, Australia.

The health data is modelled estimates based on random effects logistic regression models fitted to data from the 2011-12 and 2014-15 National Health Survey (NHS), 2011 Australian Census of Population and Housing, 2012 and 2015 Estimated Resident Population (ERP), and aggregated administrative data such as from the Department of Social Services. This data presents the modelled count and percentage of persons living in private dwellings, with the following health characteristics.

• Males and females aged 18 years and over who were current smokers.
• Persons aged 18 years and over with high or very high psychological distress, based on the Kessler 10 (K10) scale.
• Persons aged 15 years and over, with fair or poor self-assessed health.
• Persons aged 18 years and over who had high blood pressure (measured systolic/diastolic blood pressure was equal to or greater than 140/90 mmHg).

These modelled estimates were originally produced as a consultancy for the Public Health Information Development Unit (PHIDU), applying ABS methods and quality standards. Data has been produced for Statistical Area Level 3 regions.

Internal migration is the movement of people between and within Australia's states and territories and is estimated using administrative data. The main source of data used to do this is Medicare change of address information provided to the ABS by the Department of Human Services. The Medicare data used is coded directly to the ASGS and aggregated to the SA2 and LGA levels. Interstate moves are constrained to published estimates of interstate migration.

Overseas migration including arrivals and departures are prepared by breaking down state/territory level net overseas migration (NOM) arrivals and departures into sub-state areas, using information from the most recent Census. For the purposes of NOM, a person is regarded as a usual resident if they have been (or expect to be) residing in Australia for a period of 12 months or more. This 12-month period does not have to be continuous and is measured over a 16-month period. It includes all people, regardless of nationality, citizenship or legal status, who usually live in Australia, with the exception of foreign diplomatic personnel and their families.

For further information see Regional Population.

The Jobs in Australia statistics are sourced from the Linked Employer Employee Dataset (LEED) using Australian Tax Office (ATO) administrative data linked to ABS Business Longitudinal Analytical Data Environment (BLADE). 

The LEED covers all persons who either:

• submitted an individual tax return (ITR); or
• had a Pay As You Go (PAYG) payment summary issued by an employer and then remitted to the ATO. 

Employees who did not submit a tax return and have not provided their Tax File Number to their employer will not appear in the LEED. Owner managers of unincorporated enterprises (OMUEs) who did not submit an ITR are also excluded.
Jobs in Australia job counts differ from the filled job estimates from other sources such as the Australian Labour Account and Labour Force Australia. The Jobs in Australia data provide insights into all jobs held throughout the year, while the Labour Account data provide the number of filled jobs at a point-in-time each quarter (and annually for the financial year reference period), and Labour Force Survey data measure the number of people employed each month. 
Number of employee jobs refer to jobs for which the occupant received remuneration in wages, salary, payment in kind, or piece rates. This excludes self-employment jobs held by owner managers of unincorporated enterprises.
The sum of the individual components will not necessarily add up to the total number of employee jobs as the total includes jobs where the industry was unknown or missing.
Regions with small numbers should be interpreted with caution as random adjustment has been applied to this data. Prior year data included in this release of Data by region may differ slightly from previous releases due to the introduction of a revised confidentiality approach.

For further information see Jobs in Australia.

Based upon the boundaries in the Australian Statistical Geography Standard 2016 and 2018 Local Government Areas. The area of these regions were calculated on the Albers Projection using ABS standard Geographic Information Systems software using the digital boundaries of the regions.

Land cover refers to the observed physical and biological cover of the Earth's surface and includes natural vegetation and abiotic (non-living surfaces). Data was sourced from Digital Earth Australia (DEA) land cover spatial product for the 2015 calendar year. The DEA platform uses spatial data and images recorded by satellites orbiting our planet to detect physical changes across Australia. The land cover classification is based on the Food and Agriculture Organisation (FAO) Land Cover Classification Systems (LCCS, version 2). The spatial product was resampled to a 250m resolution to be consistent with the specifications for the National Land Account. Each 250m cell represents 6.25 hectares and was assigned to one land cover class. 

The 2016 ASGS boundaries were converted to match the 250m grid format. Differences between the total area covered in the land cover product and the total area in the ASGS product are due to the conversion of the ASGS boundaries to the 250m resolution. The total area belonging to a specific land cover class in a particular region is the count of cells belonging to the class within the region multiplied by 6.25. Area values are rounded to the nearest whole number.

Land tenure is the manner in which a party holds or occupies an area of land. It is a way of identifying who has the right to use and occupy land in accordance with the different types of ownership. 
Data was sourced from the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) and covers the 2015-16 financial year. The data combines jurisdictional land title information from digital cadastre databases and other sources into a national classification. The spatial product is raster format with a 250m resolution. Each 250m cell represents 6.25 hectares and was assigned to one land tenure class. The 2016 ASGS boundaries were then converted to match the 250m grid format. The differences in total area for a region in the land tenure product and in the ASGS product are due to the conversion of the ASGS boundaries to the 250m resolution. More information is available at Land tenure of Australia 2010-11 to 2015-16. The total area belonging to a specific land tenure class in a particular region is the count of cells belonging to the class within the region multiplied by 6.25. Area values are rounded to the nearest whole number.

The mean household net worth data is modelled estimates based on a Generalised Linear Mixed Model (GLMM) method using a gamma distribution and log link function, fitted to data from the 2015-16 Survey of Income and Housing, 2016 Australian Census of Population and Housing, 2016 Estimated Resident Population, and various administrative data.

This data presents experimental modelled estimates for mean household net worth for small areas. Net worth refers to economic resources in the form of the balance of assets and liabilities held by members of a household. Net worth is calculated as the difference between the stock of household assets and the stock of household liabilities. The ABS recommends that these experimental small area estimates be used for comparison between small areas only, as opposed to using the figures as estimates of mean household net worth amounts.

These experimental modelled estimates were originally published as part of the ABS response to the COVID-19 pandemic in order to determine the location and size of vulnerable populations across Australia. Data has been produced for SA2, SA3, SA4 and LGA boundaries. For further information see Household Income and Wealth, Australia, 2015-16.

The Motor vehicle census includes all vehicles registered with a state, territory or other government motor vehicle registry for unrestricted use on public roads as at 31 January, with the following exceptions:

• recreational vehicles such as trail bikes and sand dune buggies intended for off-road use in most states (in Victoria and Queensland these vehicles must be registered and are included in the statistics)
• consular vehicles
• vehicles registered by the defence forces

It includes vehicles registered at the date of the census, or that had registration expire less than one month before that date. Motor vehicle census data is presented by region of owner, and based on the postcode of the owner.

The Australia total includes records that could not be allocated to a state or territory. Therefore aggregated state and territory totals will not equal the Australia total.

The sum of the individual components of vehicles will not necessarily add up to total registered motor vehicles as the total includes vehicles where the year of manufacture was not stated or invalid.

A geographic correspondence has been used in order to present the postcode data on ASGS boundaries. Aggregated lower levels of the ASGS (SA2, SA3, LGA, etc.) within a state will not equal the state totals, due to the nature of corresponding data from postcodes. See Geographical correspondences for further information.

Random adjustments have been applied to this data and therefore data does not match source published data.

Note that not all state and territory motor vehicle registration authorities currently identify hybrids separately. For 2019, where possible the data for hybrid and electric vehicles were investigated to improve the quality of coding for these vehicle types. This has resulted in some variations to electric vehicle data when compared to previous years. This improvement is noted in the microdata publication (9309.0.55.003) -> Summary -> Survey Methodology -> Data Quality.

Further information can be found in Motor Vehicle Census, Australia.

Some data in the Aboriginal and Torres Strait Islander Peoples theme comes from the 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS).

The 2018–19 NATSIHS was conducted between July 2018 and April 2019.

• It collected information from Aboriginal and Torres Strait Islander people of all ages in non-remote and remote areas of Australia, including discrete Indigenous communities.
• Funding for the survey was provided by the Australian Government Departments of Health and Prime Minister and Cabinet.
• Previous surveys have been conducted in 2012–13 and 2004–05. Some health data was also collected in the 2014–15, 2008 and 2002 National Aboriginal and Torres Strait Islander Social Surveys (NATSISS).
• It collected information on a number of topics for the first time, including mental health conditions, medications, consumption of sugar sweetened and diet drinks, experiences of harm and a hearing test.

For information on NATSIHS items in this product, please see the Glossary of the National Aboriginal and Torres Strait Islander Health Survey. Information about guidelines and measures used to assess specific lifestyle and related factors that impact on health is included in the Appendix - assessing health risk factors.

Some data in the Aboriginal and Torres Strait Islander Peoples theme comes from the 2014-15 National Aboriginal and Torres Strait Islander Social Survey (NATSISS).

The NATSISS was most recently conducted from September 2014 to June 2015 with a sample of 11,178 Aboriginal and Torres Strait Islander people living in private dwellings across Australia in remote and non-remote areas in all states and territories of Australia. This included discrete Aboriginal and Torres Strait Islander communities. The NATSISS provides broad, self-reported information across key areas of social interest for Aboriginal and Torres Strait Islander people, primarily at the national level and by remoteness.

In the 2014-15 NATSISS, funding was received from the Commonwealth Department of Health to enable the continued collection of data on Aboriginal and Torres Strait Islander children aged 0–14 years. Funding was also received from the Department of the Prime Minster and Cabinet to enable the collection of new information relating to 'community strength and leadership'.

For information on NATSISS items in this product, please see the Glossary of the National Aboriginal and Torres Strait Islander Social Survey.

The numbers of patents and trademarks relates to applicants. They are a yearly aggregate of applicants at 31 December for the reference year. ABS has suppressed data for regions in certain circumstances to prevent the identification of individuals.

The patent and trademark applicants data is collected by IP Australia. Data produced by IP Australia can be sourced at data.gov.au. The SA3 level data have been created and published by the Office of the Chief Economist, based on postcode (of applicant) data provided by IP Australia. ABS has aggregated the SA3 data to create details for the SA4, GCCSA, state, territory and Australia geographic levels. As such, the SA4, GCCSA, state or territory and Australia totals of applicants are not official aggregates provided by IP Australia or the Office of the Chief Economist.

Personal income tax data is supplied by the ATO to the ABS under the Taxation Administration Act 1953, which requires that such data is only used for the purpose of administering the Census and Statistics Act 1905. Any discussion of data limitations or weaknesses is in the context of using the data for statistical purposes, and is not related to the ability of the data to support the ATO's core operational requirements. Legislative requirements to ensure privacy and secrecy of this data have been adhered to. In accordance with the Census and Statistics Act 1905, results have been confidentialised to ensure that they are not likely to enable identification of a particular person or organisation.

Personal Income data is also compiled from the LEED, which is built using Australian Tax Office (ATO) administrative data linked to ABS Business Longitudinal Analytical Data Environment (BLADE). The data in this release includes employee income, own unincorporated business income, investment income, superannuation and annuities income, other income (excluding Government pensions and allowances) - and total income from these component sources. See glossary for how these items have been defined or Personal Income in Australia for more information on these income types and the line items from the tax form used to calculate them.

For the purposes of providing statistical measures for the entire population, the ATO database has some limits to its coverage. Persons who receive an income below certain levels  (the tax-free threshold) are not necessarily required to lodge a tax return, and some income can be exempt and therefore does not need to be reported in tax returns. As a result, Government pensions, benefits or allowances are excluded from the other income or total income. The ATO data should be regarded as an indicative but not complete picture of all individual income earned in Australia.

The Gini coefficients shown in this publication are subject to under-coverage for certain income groups and are calculated from gross personal income rather than equivalised disposable income. They can be regarded as indicative but not definitive and are not directly comparable to apparently similar ABS information at state/territory level, as per Household Income and Wealth, Australia.

Non-lodgers have been included in the Employee income data. The ABS defines non-lodgers as individuals that have a payment summary issued by an employer but have not lodged an income tax return within the 16 month period after each financial year. Note that as the sources of income other than employee income cannot be captured for the non-lodger population, they have been excluded from the estimates of total income.

The total number of individuals in receipt of income from at least one source should not be confused with the sum of the individuals in each income category, since people can have more than one source of income in any given year.

Net income from a specific source may be positive or negative. For example, an individual may have positive income from employee income but have negative net investment income. The number of individuals for each income source includes all persons with either positive or negative net income from that source.

Main source of earners is presented as a proportion of the population in that region. If a region is particularly reliant on one source, it may be susceptible to policy or economic changes that affect that income type - hence the inclusion. Where persons receive exactly the same amount across multiple sources of income, they have been excluded from the derivation of this indicator. Persons with negative or nil total income have also been excluded. The non-lodger population has also been excluded from this calculation as the sources of income other than employee income cannot be captured.

Counts of business-related and non-business-related personal insolvencies by region are provided for reference year ended 30 June.

Data is provided by the Australian Financial Security Authority (AFSA) from their extensive personal insolvency collection. Unless an individual declares their situation to be directly related to a proprietary interest in a business, all other insolvencies (even those for which details are not stated) are classified as Non-business related.

A confidentialisation process has been applied to these data. Official statistics and more information can be found on the AFSA website.

Refers to areas of land dedicated to the protection and maintenance of biodiversity. Sourced from the Collaborative Australian Protected Areas Database (CAPAD), Commonwealth of Australia, maintained and updated by the Department of Agriculture, Water, and the Environment (DAWE). 

The Department has especially analysed CAPAD data (based on Geographic Information System Area using an Albers Equal Area Projection for Australia) into ABS Statistical Geographies - such as Statistical Area Level 2 (SA2) and Local Government Areas (LGA) - to match the geographic preferences of the ABS Data by Region dataset.

The process of splitting CAPAD into geographic regions can generate many small areas. Slivers of land - with an area less than 1 hectare and which are less than 2 per cent of the unsplit protected area - have been removed. Therefore there is a small difference between area totals for States when compared with LGA or SA2 regions. Also, the numbers of Protected Land Areas (PLAs) should be considered as indicative only as individual PLAs are often split across more than one ABS Statistical Geography and therefore counted more than once when totalled for all geographic regions.

Data is presented for:

• number of Protected Land Areas (PLAs) by selected types (for example, Nature Reserves, Indigenous Protected Areas); 
• area of PLAs (hectares); and PLAs (hectares) as a percentage of total regional land area.

Other data, for example relating to PLA types, land governance arrangements and marine regions, are readily available from DAWE. For more information please refer to Department of Agriculture, Water, and the Environment CAPAD.

Data refers to median price and transfer counts of established houses and attached dwellings for year ended 30 June of each reference year. Data are not presented prior to 2017 for regions where the geographical boundary changed from ASGS 2011 to ASGS 2016.

All Australian residential property sales data are supplied to the ABS by research firm CoreLogic. This dataset is a combination of residential property sales data obtained from state and territory land titles offices or Valuers General offices, and real estate agents' data provided to CoreLogic. The ABS applies classifications to the dataset provided by CoreLogic to create the residential property sales dataset from which these statistics are produced. Caution should be taken when interpreting data for regions where there are a small number of transfers.

As the ABS receives more unit record residential property sales data for previous financial years, the median prices and the number of house and attached dwelling transfers are revised as necessary. 

Dwellings in scope comprise:

• ordinary detached houses
• houses with offices
• houses with flats
• rural residential houses (not part of a farming business) 
• semi-detached, row and terrace houses
• townhouses
• flats, units and apartments

For further information see Residential Property Price Indexes: Eight Capital Cities.

All government pensions and allowances refer to a point in time (i.e. the number of persons who received payment as at the pay period closest to 30 June each year) and therefore do not represent all the customers in receipt of payments during the entire financial year. Unless otherwise specified, data is sourced from the Department of Social Services Demographic Data available on data.gov.au.

Where a person could not be allocated to a region within a state or territory, they have been included in the totals for the states and territories. Where a person could not be allocated to a state or territory, they have been included in the total for Australia. For privacy reasons, all administrative data from non-ABS sources has been confidentialised before being supplied to the ABS. The cells suppressed or altered through confidentialisation within Data by region may differ to other publications that contain this data.

Some payments are described in further detail below; for other items see the Glossary. More information about specific payments can be accessed from the Department of Social Services and the Department of Veterans' Affairs, or from data.gov.au.

Age Pension age depends on the individual's date of birth. please see Age Requirements for more information. The majority of Age Pensions are paid by Centrelink. Age pensioners who also receive a Disability Pension from the Department of Veterans' Affairs (DVA) have the choice of having their Age Pension paid by either the DVA or Centrelink and there are two separate data items, Age Pension and Age Pension (DVA). The Centrelink Age Pension Data is provided by DSS and includes overseas pension recipients in the Australian total.

Around 75% of all families with at least one dependent child aged under 16 years are eligible to receive Family Tax Benefit (FTB). Family Tax Benefit Part A can be paid to a parent, guardian or an approved care organisation to help with the costs of raising children. There are eligibility requirements involving the age and educational status of the child, residency, and income. Family Tax Benefit Part B is an extra payment for single parents and families with one main income to help with the costs of raising children. Part B is limited to families where the primary earner has an adjusted taxable income of $100,000 or less per financial year (from June 2015, previously was $150,000 or less). There are also additional eligibility requirements.

Approximately three-quarters of FTB customers receive both Part A and Part B. Data presented in regard to Family Tax Benefit refer only to fortnightly instalment customers were paid directly by Centrelink. The information excludes an additional 10% (approximately) who are paid by a lump sum which is claimable at the end of a financial year. The Family Tax Benefit data for the latest year are preliminary only. Users should refrain from making direct comparisons with data from earlier years in past issues of Data by region.

Small-scale solar panel installations and solar water heater installations data have been sourced from the Clean Energy Regulator (CER). The Clean Energy Regulator administers the Small-Scale Renewable Energy Scheme (SRES) as part of the federal governments Renewable Energy Target (RET). The SRES is governed by the Renewable Energy (Electricity) Act 2000 and the Renewable Energy (Electricity) Regulations 2001.

Installation counts include new, upgraded, and replacement installations, and includes stand-alone (off-grid) installations. The data only represent installations that have passed the CERs auditing process and relevant standards, and have had Small-scale Technology Certificates (STCs) validly created under the SRES. The data do not include installations that have resulted in failed STC creation, or are pending STC creation. Installations under the SRES may include residential and commercial systems, and include installations of no more than 100 kilowatts in panel array capacity.

CER data is based on the postcode of the installation. A geographic correspondence has been applied by ABS to create data on ASGS and LGA boundaries. See Geographical correspondences for further information.

• serviced apartments with 15 or more rooms or units

Further information can be found in Tourist Accommodation, Australia.

Sourced from Agricultural Census data. Data was collected from agricultural businesses on the ABS Business Register undertaking agricultural activity above a minimum size cut off of $40,000. The estimates are based on responses to the Agricultural Census and since not all of the businesses that were selected provided data, the estimates are subject to sampling variability. That is, estimates may differ from figures that would be produced if all businesses had provided data. In Data by region, Water Use data with a relative standard error (RSE) greater than 50% are not presented.

Area of agricultural land (ha) and Area irrigated (ha) may not correspond entirely to the region the data is assigned to. In some circumstances a farm may be across more than one region; the agricultural land and area irrigated will be typically assigned to the region where the address of the farm is located.

For further information see Water Use on Australian Farms.

People who identified their origin as being Aboriginal, Torres Strait Islander, or both Aboriginal and Torres Strait Islander.

The ABS Standard Indigenous Question is based upon the Commonwealth working definition but does not include the third element of the Commonwealth definition, namely that ‘an Aboriginal or Torres Strait Islander is a person who is accepted as such by the community in which he or she lives’. Collecting information on the basis of community acceptance is often impractical in a survey or administrative data collection setting and can lead to inaccuracies. For these reasons, it is not included in the ABS Standard. The definition of Indigenous Status is therefore operationalised as whether or not a person identifies as being of Aboriginal or Torres Strait Islander origin.

The term 'origin', when used in the context of the operational definition, is considered to relate to a person's Australian Aboriginal and/or Torres Strait Islander descent and for some, but not all, their cultural identity.

The Construction industry is engaged in the construction of buildings and other structures, additions, alterations, reconstruction, installation and maintenance and repairs of buildings and other structures.

The Core Activity Need for Assistance variable has been developed to measure the number of people with a profound or severe disability. As with the ABS Surveys of Disability, Ageing and Carers, the Census of Population and Housing defines the profound or severe disability population as: 'Those people needing help or assistance in one or more of the three core activity areas of self-care, mobility and communication, because of a long-term health condition (lasting six months or more), a disability (lasting six months or more), or old age'.

Persons with Business related or Non-business related insolvency.

A person has a disability if they have an impairment which restricts their everyday activities and has lasted, or is expected to last, for at least six months. A person with a disability is classified by whether they have:

• a specific limitation with any core activities (mobility, communication and self-care)
• a specific restriction when participating in schooling or employment activities, or
• no specific limitation with core activities or restriction with schooling or employment activities.

A person has a specific limitation with a core activity if they need help from another person, have difficulty or use an aid or other equipment to perform at least one selected task. The level of limitation for each core activity is based on the amount of help a person needs with a selected task:

• profound — unable to do or always needs help with a core activity task
• severe — sometimes needs help or has difficulty with a core activity task
• moderate — does not need help but has difficulty with a core activity task
• mild — does not need help and has no difficulty, but uses aids or equipment or has other limitations with a core activity task

A person's overall level of core activity limitation is determined by their highest level of limitation in any of these activities. For example, if a person has a profound limitation with a communication task and a moderate limitation with a self-care task, the person is categorised as having a profound disability.

A person has a schooling restriction if, because of their disability, they:

• are not attending school/undertaking further study
• need time off school or study
• attend special classes or a special school
• have other related difficulties.

A person has an employment restriction if, because of their disability, they:

• are restricted in the type of job they could do
• are restricted in the number of hours they can work
• have difficulty finding suitable work
• need time off work
• are permanently unable to work.

A person with a ‘schooling/employment restriction only' is someone who reported no limitations with any of the core activities but reported having difficulty with schooling and/or employment activities.

A dwelling may comprise part of a building or the whole of a building. Regardless of whether they are self-contained or not, units within buildings offering institutional care (e.g. hospital) or temporary accommodation (e.g. motels, hostels and holiday apartments) are not defined as dwelling units. Such rooms are included in non-residential building approvals. Dwellings can be created in one of four ways: through new work to create a residential building; through alteration/addition work to an existing residential building; through either new or alteration/addition work on non-residential building or through conversion of a non-residential building to a residential building.

When all persons in the population are ranked from the lowest to the highest on the basis of some characteristic such as their income, they can then be divided into equal sized groups. Division into 100 groups gives percentiles. The highest value of the characteristic in the twentieth percentile is denoted P20. The median or the top of the 50th percentile is denoted P50. P20, and P80 denote the highest values in the 20th, and 80th percentiles. Ratios of values at the top of selected percentiles, such as P80/P20, are often called percentile ratios.

Percentile ratios summarise the relative distance between two points in a distribution. To illustrate the full spread of the income distribution, the percentile ratio needs to refer to points near the extremes of the distribution, for example, the P80/P20 ratio. The P80/P50 and P50/P20 ratios focus on comparing the ends of the income distribution with the midpoint.

The errors associated with the modelled estimates for small areas fall into four categories. Sampling error, non-sampling error, modelling error, and prediction error. The relative root mean square error (RRMSE) provides an indication of the deviation of the modelled estimate from the true value. The RRMSE is primarily a measure of prediction error, but in its calculation it also inherits some aspects of modelling and sampling error.

The relative standard error (RSE) is a measure of sampling variability which is obtained by expressing the standard error as a percentage of the estimate to which it refers. For example, if the estimate is 0.5 and the standard error is 0.05, then the relative standard error will be 10%. The relative standard error is a useful measure in that it provides an immediate indication of the percentage of errors likely to have occurred due to sampling and thus avoids the need to refer also to the size of the estimate.
