MELBOURNE METROPOLITAN AREA
7 Most of the small area data provided by non-ABS organisations are aggregates at Local Government Area (LGA) level. With one exception, LGAs do not cross Statistical Division (SD) boundaries, and therefore it is generally possible to form SD data from aggregate LGA data. However, while the majority of the Yarra Ranges (S) LGA is in the Melbourne SD, the Yarra Ranges (S) - Pt B SLA is in the Gippsland SD. As a result, in these instances it is not possible to derive data for Melbourne and Gippsland SDs as exactly defined in the Australian Standard Geographical Classification (ASGC) (cat. no. 1216.0).
8 Where necessary, the Yarra Ranges (S) LGA as a whole is included with the LGAs in Melbourne SD to form a region referred to as the Melbourne Metropolitan Area (MMA). Consequently, in these instances Gippsland SD excludes Yarra Ranges (S) - Pt B SLA.
9 As an indication of the relative size of Yarra Ranges (S) - Pt B SLA, at 30 June 2008 it had a preliminary estimated resident population (ERP) of 612 persons. At the same date, the total ERP of Yarra Ranges (S) LGA was 146,886, while Gippsland SD had a total ERP of 170,779.
GEOGRAPHY AND MAPS
10 Maps of SLAs and SDs within Victoria can be found in Australian Standard Geographical Classification (ASGC) (cat. no. 1216.0) on the Downloads page (1216.0 - 2009 ASGC - Victorian Maps). A listing of SLAs within each LGA (Local Government Areas and Statistical Local Areas - Alphabetic) can be accessed from the same page, along with listings of SLAs within each SD (Main Structure - Detailed) and Statistical Region (SR) (Statistical Region Structure - Detailed).
11 Unless otherwise indicated, boundaries of LGAs, SDs and SRs referred to in this publication are consistent with those in the 2009 Edition of the ASGC. The most recent change to an LGA boundary in Victoria was effective from 1 July 2008 and involved Melbourne (C) gaining 111.8 hectares (and 5,712 persons based on preliminary ERP at 30 June 2008) from Moonee Valley (C).
Regional and small area labour force estimates
12 The regions in Victoria for which the ABS produces estimates from the Labour Force Survey are revised at the time of the labour force sample redesign following each Census of Population and Housing and remain stable until the next labour force sample redesign. From November 2007, these regions are consistent with the SRs in the 2006 Edition of the ASGC. Consequently, the LGA boundary change between Melbourne (C) and Moonee Valley (C) is not reflected in LFS data. There were no changes to Victorian SR boundaries between 2001 and 2006 that involved population. For further information on LFS data at regional level, please see Information Paper: Regional Labour Force Statistics (cat. no. 6262.0). Maps of SRs used in the LFS can be found in Australian Labour Market Statistics, Jul 2009 (cat. no. 6105.0) on the Downloads page (6105.0 - Labour Force Region Maps - Victoria - 2007).
13 The quarterly small area unemployment rate estimates produced by DEEWR are based on the regions used by the ABS in the LFS. Even though there were no changes to Victorian SR boundaries between 2001 and 2006, there have been changes to LGA boundaries involving population which may have impacted on the small area unemployment rate time series. These boundary changes have been incorporated into the estimates for the smoothed series (the series included in this publication) from September quarter 2008, and have not been backcast to earlier periods. In Victoria, the affected LGAs are:
14 Changes to internal SLA boundaries between 2001 and 2006 have affected the timing of the introduction of new LFS population benchmarks based on the 2006 Census of Population and Housing into the small area unemployment rate time series for the LGAs of Baw Baw (S), Campaspe (S), Colac-Otway (S), Greater Bendigo (C), Knox (C), Whittlesea (C) and Yarra Ranges (S). For these LGAs, the new benchmarks have been incorporated from September quarter 2008, which is two quarters later than other LGAs. The new benchmarks for Alpine (S) and Unincorporated Vic. have also been introduced from September quarter 2008.
15 The boundary changes to geographic areas and new population benchmarks described above were first introduced into the small area unemployment rate time series in March quarter 2009, with data for previous periods being revised back to either March quarter 2008 or September quarter 2008 (depending on the nature of revisions required, as described above).
16 Tourism Regions are defined by relevant state/territory tourism organisations and represent groups of SLAs. Each year, any changes to Tourism Regions (including SLA boundary changes incorporated in the current edition of the ASGC) are applied from the first reference period of the Survey of Tourist Accommodation in the following calendar year (i.e. the March quarter). For a map of Victorian Tourism Regions, and a listing of SLAs within each Tourism Region, please see Tourism Region Maps and Concordance Files, Australia (cat. no. 9503.0.55.001).
17 This publication contains maps illustrating selected characteristics relating to the population in LGAs.
18 For each map, five class intervals, each with a different colour shade, have been used to help interpret the distribution of the characteristic being mapped. LGAs with similar values are grouped in the same class, and the number of LGAs in each class will vary depending on the distribution of the population being mapped.
19 Each map contains a legend showing the colour and values for each class of the mapped data. For simplicity, the ranges are shown as, for example, '9.7-16.3' and '16.3-23.0'. These should be read as 'from 9.7 to less than 16.3' and 'from 16.3 to less than 23.0'. Individual values appear in one range only.
