National Regional Profile: Explanatory Notes  
   Page tools: Print Print Page Print all pages in this productPrint All



1. The Regional Profile presents a standard set of data for the following levels of the Australian Standard Geographical Classification (ASGC):
Statistical Local Area (SLA), Local Government Area (LGA), Statistical Subdivision (SSD), Statistical Division (SD), State/Territory and Australia.

2. The data are sourced from a wide variety of collections, both ABS and non-ABS. When analysing the data care needs to be taken as time periods, definitions, methodologies, scope and coverage differ between collections. Where available, data have been presented as a time series. Time series data enable us to assess levels of social and economic activities over time. However, looked at on a period to period basis, these series may be volatile. When analysing the data, users are encouraged to consider the longer term behaviour of the series, where this is available.

3. While information on the datasets and terms used in this profile are included below and in the accompanying
Glossary, more detailed information can be obtained by referring to the relevant source listed for each dataset.

4. All data are shown for boundaries as described in the 2004 edition of the ASGC (ASGC 2004). For further information see the "Statistical Geography: Volume 1 - Australian Standard Geographical Classification", 2004 (ASGC), cat. no. 1216.0, ABS, Canberra, Annual.
For further information on how data has been presented on ASGC 2004, see geographical concordances at paragraphs 102 to 108 of these Explanatory Notes.

Estimates of Unemployment

5. Unemployment estimates for small areas are produced by the Department of Employment and Workplace Relations (DEWR) using the Structure Preserving Estimation (SPREE) methodology.

6. SPREE uses Commonwealth Department of Family and Community Services (Centrelink) statistics of persons in receipt of unemployment benefits and ABS population and labour force estimates by labour force regions to estimate unemployment levels. Sampling and non-sampling errors in these collections will flow into the DEWR estimates.

7. This methodology produces original, unadjusted estimates which can exhibit considerable variability. The data shown in the National Regional Profile have been 'smoothed' by averaging the original data over the last four quarters to September. Particular care should be taken when interpreting estimates for regions where the estimated labour force is smaller than 1000 persons.

8. DEWR produced the estimates on ASGC 2001 boundaries so a geographic concordance has been used to present the data based on ASGC 2004. Further information on
geographic concordances can be found in paragraphs 102 to 108.

9. A detailed description of the SPREE methodology used in deriving the estimates is presented in the DEWR quarterly publication "Small Area Labour Markets, Australia" or can be accessed through the DEWR web site at

Local Government Finance

10. The Local Government Finance data displayed are from the ABS Government Finance Statistics collection.

11. The system of Government Financial Statistics (GFS) provides details of revenues, expenses, cash flows and assets and liabilities of the Australian public sector.

12. Local government authorities are responsible for areas typically described as cities, towns, shires, boroughs and municipalities. Although the range of functions undertaken by local governments varies between the different jurisdictions, their powers and responsibilities are generally similar and cover such matters as:

  • the construction and maintenance of roads, streets and bridges;
  • water, sewerage and drainage systems;
  • health and sanitary services;
  • the regulation of building standards; and
  • the administration of regulations relating to items such as slaughtering, weights and measures, and registration of dogs.

13. Local governments also provide transport facilities, hospitals, charitable institutions, recreation grounds, parks, swimming pools, libraries, museums and other business undertakings. Local governments' own-source revenue is derived mainly from property taxes. They also rely on grants from the Commonwealth and their parent state governments. The Australian Capital Territory has no separate local government.

14. Further information relating to Local Government expenditure can be found in Government Finance Statistics, Australia (cat. no. 5512.0).

15. Detailed information on the concepts, sources and methods used in compiling GFS can be found in Australian System of Government Finance Statistics: Concepts, Sources and Methods (Cat. no. 5514.0),which is available on the ABS Web site, released September 2005.

Selected income support customers

16. The term 'Selected income support customers' has been used to define persons receiving specific payments from various Australian Government Department of Family and Community Services (FaCS) programs for the years shown (in 2004 the responsibility for some payments were transferred from FaCS to the Department of Employment and Workplace Relations and to the Department of Education, Science and Training). The statistics shown have been compiled from data collected by Centrelink which is the government agency delivering income support payments and services to eligible members of the community on behalf of FaCS for the years shown.

17. Centrelink customers complete claim forms in order to determine their eligibility for payments and services. The type of payment being claimed determines what form is used and how frequently claim forms need to be submitted.

18. People receiving more than one payment are only counted once by using the main payment type. Data for Age Pension, Disability Support Pension, Newstart Allowance, Parenting Payment - Single and Youth Allowance are shown separately while the following main payment types have been grouped in the "other pensions and allowances" category: Austudy, Carer Allowance, Carer Payment, Double Orphan Pension, Exceptional Circumstances, Mobility Allowance, Newstart Mature Age Allowance, Parenting Payment Partnered, Partner Allowance, Sickness Allowance, Special Benefit, Widow Allowance, Wife Pension and Widow Class B. Brief descriptions of each payment type are included in the

19. Excluded from the data presented in this profile are persons whose main payment type is Bereavement Allowance, Childcare Benefit, Farm Family Restart or Family Tax Benefit Part A or B.

20. Counts of income support customers include those receiving a payment and those customers temporarily suspended from payment or not paid in the fortnight (zero paid) due to income/assets test provisions or other administrative procedures. Age Pension counts exclude payments made to persons overseas and age pensions paid by the Department of Veterans' Affairs.

21. The percentage of long-term Newstart Allowance customers and the number of Newstart Allowance customers come from different Centrelink databases. The data used to calculate the percentage of long-term Newstart Allowance customers exclude those persons temporarily suspended from payment or zero paid. Consequently, the percentages should not be applied to the Newstart Allowance numbers.

22. Data are for the fortnightly pay period closest to the end of June 2002 and the end of June 2003.

23. The statistics shown have been provided to the ABS in aggregated form only. No information about individual income support customers has been released to the ABS. A geographic concordance has been used in order to present the original postcode data on ASGC 2004 boundaries. Note that the use of this concordance may lead to total numbers for States/Territories which differ slightly from State/Territory totals published by Centrelink. Further information on
geographic concordances can be found in paragraphs 102 to 108.

24. To preserve the confidentiality of individuals data for some areas have been added to data for other areas. The list below gives details of the areas effected by these amalgamations:
    • Data for SLA 18859 Lord Howe Island is included in SLA 13754 Hastings (A) - Part B.
    • Data for SLA 20573 Ballarat (C) - North is included in SLA 20572 Ballarat (C) - Inner North.
    • Data for SLA 28529 French Island is included in SLA 20744 Bass Coast (S) Bal.
    • Data for SLA 48899 Unincorporated Western is included in SLA 45898 Port Adelaide Enfield (C) - Port.
    • Data for SLA 49039 Unincorporated Riverland is included in SLA 46674 Renmark Paringa (DC) - Renmark.
    • Data for SLA 49179 Unincorporated Lincoln is included in SLA 43710 Lower Eyre Peninsula (DC).
    • Data for SLA 49389 Unincorporated Whyalla included in SLA 48540 Whyalla (C).
    • Data for SLA 46970 Roxby Downs (M) is included in SLA 49589 Unincorporated Far North.
    • Data for SLA 62811 Hobart (C) - Inner is included in SLA 62812 Hobart (C) - Remainder.
    • Data for SLA 64011 Launceston (C) - Inner is included in SLA 64012 Launceston (C) - Pt. B.

25. These amalgamations also flow into the addition of these SLAs to LGAs, but do not affect totals for SSDs or higher geographical areas.

26. Detailed information on specific payments and eligibility requirements can be found on the Centrelink web site at

Average Individual Annual Taxable income

27. The average individual annual taxable income data have been sourced from the annual Australian Taxation Office (ATO) publication and CD-ROM 'Taxation Statistics'. (These are also available on the Tax Office web site at

28. The main functions and responsibilities of the ATO are to administer taxation legislation and to collect a wide variety of taxes. The ATO therefore collects data from its reporting population as part of its processes to calculate income tax liability for those persons who are required to lodge an income tax return.

29. Individuals who submit an individual income tax return report their total income from various sources over a financial year. Their taxable income is the amount remaining after deducting from assessable income all deductions allowed under the Income Tax Assessment Act and is the amount to which tax rates are applied.

30. The average individual annual taxable income in an area is then calculated by dividing the total taxable income reported for an area by the total number of taxable taxpayers.

31. A geographic concordance has been used in order to present the original postcode data on ASGC 2004 boundaries. Further information on
geographic concordances can be found in paragraphs 102 to 108.

Wage and salary earners

32. The estimates for Wage and salary earners have been compiled by the Australian Taxation Office (ATO) from their Individual Income Tax Return Database.

33. Individuals who submit an individual income tax return report their income from one or more of a range of sources such as wages and salary, own business, superannuation, investments and government pensions, benefits or allowances.

34. As the ATO's income tax return is designed to obtain a person's total income from various sources over a financial year, and not the employment status of a person at a particular point in time, wage and salary earners have been defined as 'persons aged 15 years and over who have submitted an individual income tax return and for whom wage and salary income was the principal (or main) source of income for the financial year'.

35. Wage and salary income, as reported on the income tax return, includes gross income as shown on the 'PAYG payment summary - individual non-business' as well as allowances, commissions, bonuses, tips, gratuities, consultation fees, honoraria
, and other payments for services. Allowances and other earnings may include car, travel or transport allowances, allowances for tools, clothing or laundry and dirt, risk, meal or entertainment allowances. The data to define and compile counts of wage and salary earners have been sourced from questions 1 and 2 on the individual income tax return (Note: PAYG (Pay as You Go) payment summaries were previously known as Group Certificates).

36. All individual income tax statistics provided to the ABS by the ATO have been in aggregated form only, at the Statistical Local Area (SLA) level. Information about individual taxpayers has not been released to the ABS.

37. The statistics are based on individual income tax returns lodged for the financial year ended 30 June, regardless of the year in which they were processed.

38. A geographic concordance has been used in order to present the data on ASGC 2004 boundaries. Further information on
geographic concordances can be found in paragraphs 102 to 108.

39. Further information on these statistics can be found in the electronic publications
Regional Wage and Salary Earner Statistics, (cat. no. 5673.0.55.001) (for 1998-99 to 2000-01) and cat. no. 5673.0.55.003 for 2002-03 data.

Source of personal income

40. Experimental estimates of personal income brings together data aggregated from the Australian Taxation Office (ATO) and from the Australian Government Department of Family and Community Services (FaCS), which was responsible for income support payments for the years shown.

41. The income received by individuals have been grouped into six main categories:
    • Wage and salary income (data source - ATO)
    • Own unincorporated business income (data source - ATO)
    • Investment income (data source - ATO)
    • Superannuation and annuity income (data source - ATO)
    • Government cash benefit income (data source - FaCS)
    • Other income (data source - ATO)

42. Total gross income is the sum of the income from all these sources before income tax and the Medicare levy have been deducted.

43. Data are for the financial year ended 30 June.

44. For further information see Information paper:
Experimental Estimates of Personal Income for Small Areas, Taxation and Income Support Data, 1995-96 to 2000-01 (cat. no. 6524.0)

Land area

45. The land area figures are based upon the boundaries of the SLAs in the 2004 edition of the ASGC. The areas of the SLAs were calculated using ABS standard Geographic Information Systems software from the digital boundaries of the SLAs. Higher level spatial unit area figures are aggregations of the SLA areas.

Building approvals

46. Statistics of building work approvals are compiled from:
    • permits issued by local government 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).

47. The statistics included in this profile relate to all residential building approvals valued at $10,000 or more and all approved non-residential building jobs valued at $50,000 or more.

48. Construction activity not defined as building (eg. construction of roads, bridges, railways etc) is excluded from building statistics.

49. The data are for the financial year ended 30 June.

50. Data for Jervis Bay is included in the state total for New South Wales, while data for Christmas Island and Cocos-Keeling Islands is included in state total data for Western Australia.

51. For further information see
Building Approvals, Australia, cat. no. 8731.0

New motor vehicle sales

52. New motor vehicle sales statistics are based on the Vehicle Facts (VFACTS) service produced by the Federal Chamber of Automotive Industries (FCAI). VFACTS data are based on retail sales of new vehicles by all FCAI members.

53. Included are passenger vehicles, trucks, buses, vehicles with diplomatic and consular plates, State/Territory and Commonwealth owned vehicles and vehicles belonging to the defence forces. Excluded are motor cycles, plant and equipment and unpowered vehicles.

54. Data are for the financial year ended 30 June.

55. A geographic concordance has been used in order to present the original postcode data on ASGC 2004 boundaries. Further information on
geographic concordances can be found in paragraphs 102 to 108.

56. Data for Jervis Bay Territory are included in the Unknown AUST SLA 99999, and so included in the Australian total only. Data for Christmas Island and Cocos (Keeling) Island were included in the WA SLA 59779, and so included in the Western Australia state total.

57. Detailed monthly figures can be obtained by making inquiries to the Manager, VFACTS,
Federal Chamber of Automotive Industries on (03) 9829 1234. Some information is also available by viewing the industry summary presented on the VFACTS web site

Value of Agricultural Production

58. The value of agricultural production estimates are derived by the multiplication of price and quantity of individual agricultural commodities. Quantity data for commodities was collected at the 2000-01 Agricultural Census. Price data is the average unit value of a given commodity realised in the market place. Price information is obtained from a wide range of both ABS and non-ABS sources, including marketing authorities and industry sources.

59. The values used here are "gross value of agricultural commodities produced" and represent the value placed on recorded production at the wholesale prices realised in the market place. Market place, in general, is the metropolitan market in each state. In cases where commodities are consumed locally, or where they become raw material for a secondary industry, these points are presumed to be the market place.

60. The method of collection of relevant prices for agricultural commodities and the costs of marketing these commodities vary considerably between states and between commodities. Where a statutory authority handles marketing of the whole or a portion of a product, price data are usually obtained from this source. Price information is also obtained from marketing reports, wholesalers, brokers and auctioneers. For all commodities, values are in respect of production during the year (or season) irrespective of when payments are made.

61. Estimates for small areas such as Statistical Local Areas (SLAs) and Local Government Areas (LGAs) are only available for years in which an Agricultural Census is conducted. The most recent Agricultural Census was conducted in respect of 2000-01.

62. Value of agricultural production estimates are subject to standard error. Estimates with an RSE greater than 50% are not shown as the estimates are considered too unreliable for general use.

63. Further information on 'Value of Agricultural Production' can be obtained in the ABS publication
Agricultural Commodities, Australia (cat. no 7121.0)


64. Population figures are the estimated resident population (ERP) for the selected region as at 30 June for the year shown.
Data are shown to the nearest whole number without rounding, but accuracy to the last digit is not claimed and should not be assumed.

65. The concept of ERP links people to a place of usual residence within Australia. Usual residence is defined as that place where each person has lived or intends to live for six months or more in the reference year.

66. In census years the ERP as at 30 June for a region is based on usual residence census counts, with an allowance for net census undercount and the number of residents temporarily overseas at the census date. Overseas visitors in Australia are excluded from this calculation. As the census is held at a date other than 30 June (7 August in 2001), further adjustments taking into account births, deaths and net migration for the intervening period are made to obtain the ERP at 30 June.

67. For post-censal years, estimates at the Australian level take into account natural increase and net overseas migration, while estimates for states and territories also use estimated interstate movements involving a change of usual residence. However the absence of migration data at the SLA level means that it is not possible to estimate SLA populations by taking into account natural increase and net migration. Instead, ERPs are calculated using a mathematical model.

68. In the mathematical model a relationship is established between changes in population and changes in other indicators over the period between the two most recent censuses.

69. The choice of indicators varies across the states and territories, depending on availability, and includes dwelling approvals, electricity connections, Medicare enrolments and drivers' licences. Changes in these indicators are then used to estimate changes in the population of each area since the last census. The choice of indicators also varies across SLAs depending on aspects such as whether the SLA is urban or rural, is growing or declining, and whether the area has a high or low proportion of houses or medium and high density dwellings.

70. Local knowledge, including that advised by local governments, may be used to adjust the outcome of the model for a particular SLA.

71. A more detailed description of the ERP methodology as adopted by the ABS for official population estimates, is contained in
Demographic Estimates and
Projections: Concepts, Sources and Methods (cat. no. 3228.0)

72. Further information on ERP data can be found in
Regional Population Growth, Australia (cat. no. 3218.0).

Indigenous Population

73. The indigenous population figures are experimental estimates of the Aboriginal and Torres Strait Islander (Indigenous) population of Australia at 30 June 2001, based on the 2001 Census.

74. The indigenous population is comprised of people who are of Aboriginal origin, Torres Strait Islander origin or both Aboriginal and Torres Strait Islander origin.

75. The estimates of the indigenous population are experimental. The significant intercensal volatility in indigenous Census counts and the quality of data on births, deaths and migration do not support the standard approach to population estimation.

76. In the estimation of the indigenous population, Census counts of indigenous persons by Statistical Local Area (SLA) of usual residence were adjusted to produce the estimated population as at 7 August 2001. Next the effects of births, deaths, overseas migration and interstate migration for the 38 days between 1 July and 7 August 2001 were removed to derive 30 June 2001 estimates.

77. A more detailed description of the methodology adopted by the ABS for estimates of the indigenous population are contained in Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991 to 2009 (Cat. no. 3238.0)

Census 2001

78. The National Regional Profile presents a summary of population characteristics from the 2001 Census. More detailed data are available from the Census Theme page on the ABS website. All Census data in the National Regional Profile is on a usual residence basis (see paragraph 80).

79. The Census enumerates people where they were located on Census night. Most standard products from the Census provide characteristics of people on this place of enumeration basis. Census counts by place of enumeration: include overseas visitors for Age, Sex and Registered Marital Status; exclude overseas visitors for all other person variables; and exclude Australian residents temporarily overseas.

80. Census data are also available on place of usual residence, which is the place a person usually lives, rather than the place they were counted on Census night. Census counts by place of usual residence exclude overseas visitors and Australian residents temporarily overseas.

81. For more information, see How Australia takes a Census (Cat. no. 2903.0) and the information paper 2001 Census of Population and Housing Nature and Content (Cat. no. 2008.0).

Overseas Born Population

82. The statistics shown on Australia's overseas born population are from the 2001 Census.

83. The 'Standard Classification of Countries' (SACC) (Cat. no. 1269.0) was used to classify responses for birthplace of individuals. This classification used the current names of countries, so if a person uses a former name the current name is coded. For example, Siam would be coded to Thailand. If an individual's birthplace was not stated on the Census form, an attempt was made to derive it from other answers.

84. The data shown exclude overseas visitors, persons at sea at the time of the Census, and persons whose responses on the Census form inadequately described their country of birth or for whom the birthplace was not stated (and could not be derived).

Speaks language other than English

85. This data is from the 2001 Census and identifies the language spoken at home, and is coded using the Australian Standard Classification of Languages (ASCL) (Cat. no. 1267.0). Only one language is coded for each person.


86. The data shown describe the level of education of the highest completed non-school qualification (eg. bachelor degree, diploma).

87. 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) (Cat. no. 1272.0).


88. The Occupation figures shown are from the 2001 Census and include all employed people aged 15 yeas and over. Two 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.

89. Occupations are coded using the Australian Standard Classification of Occupations (ASCO) Second Edition (Cat. no.1220.0). The Occupation code assigned is based on the main job held during the week prior to Census Night.


90. The data on households are from the 2001 Census. The data describes the type of household within a dwelling. Family households can contain non-family members (unrelated persons and visitors).

91. A maximum of three families can be coded to a household. Lone person households can contain visitors.


92. The family data shown are from the 2001 Census. Families have been 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 based on the presence or absence of couple relationships, parent-child relationships, child dependency relationships or other blood relationships, in that order of preference.

93. 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.

Proportion of Population in Remoteness Area

94. The percentages shown indicate the proportion of the population living in each category of Remoteness for the selected region. The proportions are based on where people were on the night of the 2001 Census of Population and Housing.

95. The Remoteness Structure was added to the ASGC in 2001 in order to provide a standard geographical structure describing Australia in terms of a measurement of remoteness or distance from services. It is designed to allow quantitative comparisons between 'city' and 'country' Australia.

96. The Remoteness Structure is based upon the Accessibility/Remoteness Index of Australia (ARIA) which was developed for the former Commonwealth Department of Health and Aged Care (now Department of Health and Ageing) by the National Key Centre for Social Applications of Geographical Information Systems (GISCA). ARIA measures the remoteness of a point based on the road distances to the nearest town (service centre) in each of five population size classes. The basic premises of ARIA are that there are more services available in larger towns than small towns and that remoteness is a factor of the relative distance one must travel to access a full range of services.

97. The Remoteness Structure contains the following categories which provide a measurement of whether geographic distances impose restrictions on the accessibility to the widest range of goods, services and opportunities for social interaction:
    • Major Cities of Australia - imposes minimal restriction e.g. Sydney, Newcastle, Wollongong, Melbourne, Geelong, Brisbane, Gold Coast, Adelaide, Perth and Canberra.
    • Inner Regional Australia - imposes some restriction e.g. Tamworth, Wagga Wagga (New South Wales), Ballarat, Bendigo (Victoria), Rockhampton, Bundaberg, Gladstone (Queensland), the Adelaide Hills (South Australia), Bunbury (Western Australia), Hobart and Launceston (Tasmania).
    • Outer Regional Australia - imposes a moderate restriction e.g. Broken Hill, Griffith, Gunnedah (New South Wales), Horsham, Swan Hill, Traralgon (Victoria), Roma, Cairns (Queensland), Port Augusta, Mount Gambier (South Australia), Albany (Western Australia) and Burnie (Tasmania), and Darwin (Northern Territory).
    • Remote Australia - imposes a high restriction e.g. Cobar (New South Wales), the northern Wimmera district (Victoria), Charters Towers and Cooktown (Queensland), Port Lincoln (South Australia), the Kalgoorlie gold-fields (Western Australia), parts of the West Coast (Tasmania), Alice Springs and Katherine (Northern Territory).
    • Very Remote Australia - imposes the highest restriction e.g. The far west parts of New South Wales and Queensland, northern South Australia and Western Australia, most of the Northern Territory and Flinders and King Islands in Bass Strait (Tasmania).
98. Detailed information about the Remoteness Structure can be referenced in Information Paper: ABS Views on Remoteness, 2001 (cat. no. 1244.0) and Information Paper: Outcomes of ABS Views on Remoteness Consultation, Australia, 2001 (cat. no. 1244.0.00.001)

Population density

99. The population density for a region is calculated by dividing the estimated resident population (ERP) by the land area to obtain the number of persons per square kilometre.


100. Birth statistics are presented on the basis of the usual residence of the mother regardless of where in Australia the birth occurred or was registered. The data refer to live births registered during the calendar year shown, and are supplied to the Australian Bureau of Statistics (ABS) by each state/territory Registrar of Births, Deaths and Marriages for compilation into the aggregate statistics in this publication. For more information refer to Births, Australia (cat. no. 3301.0).


101. Death statistics are presented on the basis of the usual residence of the deceased regardless of where in Australia the death occurred or was registered. The data refer to deaths registered during the calendar year shown, and are supplied to the Australian Bureau of Statistics (ABS) by each state/territory Registrar of Births, Deaths and Marriages for compilation into the aggregate statistics in this publication. For more information refer to
Deaths, Australia (cat. no. 3302.0).

Geographic concordances

102. The data in this profile are shown for boundaries as described in the 2004 edition of the Australian Standard Geographical Classification (ASGC).

103. Where data were originally available by other geographic areas or based on a previous edition of the ASGC a geographic concordance has been applied to convert the data to ASGC 2004 boundaries.

104. These concordances (or conversions) use factors based on population to produce estimates on the desired region.

105. For example, aggregated postcode data can be used to produce estimates at the SLA level by using postcode to SLA conversion factors. The conversion factors are based on the estimated resident population for each particular year.

106. The following example shows how the concordances are applied. An SLA covers three postcode areas; all of postcode 0001 and parts of postcodes 0002 and 0003. Based on the estimated resident population at 30 June 2003, the proportions of the population, or concordance factors, in each postcode that make up the SLA were: 100.00% for postcode 0001, 26.71% for postcode 0002 and 62.60% for postcode 0003. By applying these factors to the relevant total population for each postcode, in this case the people receiving the Age Pension, an estimate of 8,530 for the SLA was derived.

SLA total

107. When analysing concorded data the following limitations of this methodology need to be taken into account:
    • in applying the concordances it is assumed that the particular characteristics of any data item are uniformly distributed across an area and therefore concorded data may not truly reflect the distribution of the characteristics of the population. In some cases, where one area is split across two or more SLAs and there are no other contributing areas, distinct numerical estimates will be derived but rates or averages will be identical for each SLA (as these will be equivalent to the original rate or average of the contributing area);
    • the conversion factors are based on total population only;
    • some official postcodes (such as PO boxes, etc.) do not correspond to residential areas but may still be reported in the current home address field. Data for these and other ‘invalid’ postcodes, such as those due to incorrect reporting or processing errors, have been included in an ‘unknown’ category for each state and territory and for Australia where the state or territory was not known.

108. While care was taken in producing and applying the concordances the ABS will not guarantee the accuracy of concorded data.

VIC - Road Traffic Fatalities & Road Traffic Major Injuries

109. Statistics on the number of number of road traffic collisions involving fatalities and major injuries in Victoria are provided by the Victoria Police Statistical Services Division. Data on fatalities are based on the reports provided by the Police members and fatal Incident Fact Sheets. Collisions and injuries data are obtained from accident report forms (VP Form 510). Due to compliance with the Federal Office of Road Safety guidelines and delays in the supply of collision data, the data may be subject to revision at a later date. For more information, refer to the Victoria Police website at

VIC - Recorded Crime Offences

110. Statistics on recorded crime offences by Victorian Police Regions are provided by the Victoria Police Statistical Services Division. Only the most serious offence in a distinct course of criminal conduct is recorded in official statistics, even though multiple charges may be laid for one incident. For example, if an offender carrying a firearm commits an armed robbery and assaults a staff member, only the armed robbery is recorded although the offender will be charged with both offences.

111. The recorded crime statistics include only those offences which become known to police and for which a crime report has been completed and are recorded between 1 July and 30 June regardless of when the offence occurred or when it was reported to police (over 85% of all offences are recorded within 48 hours of being reported to police). There are over 4000 individual statutory and common law offences are grouped into 27 broad offence categories (loosely based on the Australian National Classification of Offences). These are further aggregated into four general classes of "Crime against the Person", "Crime Against Property", Drug Offences" and "other Crime". For more information, refer to the Victoria Police website at

VIC - Condition Of Main Roads
