The current classification system categorises electorates on the basis of party safeness and socio-demographic criteria and forms an integral part of the AEC’s mandate to inform the public by making election results more meaningful. The definition and application of these criteria over the period have not been consistent and this has led to anomalies in the classification process. To address this situation the AEC has reviewed the classification system. A new system will be in place following the 2004 federal election. Classification of electoral divisions will be based on three categories: Party safeness; Geographic criteria; and Socio-economic classification. The proposed system will build on and enhance the existing categories to provide a more consistent and accurate classification system. The enhanced system will allow for better targeting of like areas by the AEC and enhance the quality of election result analysis. Current electoral division classifications The AEC currently categorises electoral divisions according to two classifications: Party safeness; and Socio-demographic criteria. Party safeness The party safeness classification categorises divisions according to the party holding the division (or notionally holding the division after the effects of a redistribution are taken into account) and the margin in two party preferred terms. In the case of a division held by an Independent the margin is based on a two candidate preferred analysis. There are currently five party categories: • Australian Labor Party (ALP); • Liberal Party (LP); • National Party (NP); • Northern Territory Country Liberal Party (CLP); and • Independent. The margin categories are classified as: • Marginal: requiring a swing of 0<6% to change; • Fairly safe: requiring a swing of between 6<10% to change; and • Safe: requiring a swing of 10%+ to change. Socio-demographic criteria The socio-demographic classification categorises divisions according to geographic location. There are four categories: 3 • • • • Inner metropolitan: located in a capital city and comprising well-established, built-up suburbs; Outer metropolitan: located in capital cities and containing areas of more recent urban expansion; Provincial: divisions with a majority of enrolment in major provincial cities; and Rural: divisions without a majority of enrolment in major provincial cities. The current classifications have been used since at least the 1975 election. Improving the classification of electoral divisions The allocation of divisions to categories has not been centrally co-ordinated and this has resulted in ad hoc, and at times inconsistent, classification decisions. Inconsistencies also occur because although there are definitions to assist in categorising divisions, these are not particularly exhaustive nor have they been consistently followed. For example, at the 2004 election the division of Capricornia was classified as provincial as 50.5% of its electors are enrolled in Rockhampton. However, both Fairfax and Leichhardt were classified as rural even though their respective enrolment was 51.1% based in the Sunshine Coast and 73.9% in Cairns. This kind of anomaly is undesirable as areas with the same demographic and geographic characteristics should be similarly classified. The two current classifications cover geographic and political considerations. They do not address socio-economic status issues. A third socio-economic classification will be added to the existing categories to enable the analysis of election results by socio-economic status as well as geographic area and party preference. A third category: socio-economic classification The Australian Bureau of Statistics (ABS) publishes Socio-economic Indexes for Areas based on aggregations of Census data. These indexes can be aggregated to electoral division level1 and provide a useful summary of the socio-economic characteristics of the area. The ABS publishes four socio-economic indexes. The “Index of Socio-Economic Advantage/Disadvantage” is a general measure of the social and economic well-being of an area and, of the four, is the most appropriate measure to indicate a division’s relative socioeconomic status. The socio-economic classification of electoral divisions will divide divisions into four roughly equal categories – high, upper middle, lower middle and low – based on each division’s index of socio-economic advantage score. Attachment 1 provides a socioeconomic index score for each electoral division contested at the 2001 federal election. Reviewing geographic classification The following table outlines revised definitions of current socio-demographic classifications. Based on the addition of the socio-economic classification to more accurately reflect issues of socio-economic status, this category will now be referred to as geographic classification and focus specifically on the characteristics of a division’s geographic area. Inner Metropolitan Divisions with an area of less than 10 000 sq kms, and Divisions with a majority of electors within capital city statistical division, and Divisions comprising well established built up suburbs. 1 The index scores for the Electoral Divisions are calculated by taking the weighted average, using population counts from the 2001 census across all Census Collection Districts for the Division. For more information see Socio-Economic Indexes for Areas Australia 2001 Australian Bureau of Statistics, Information Paper 2039.0, Section 2.2 4 Outer Metropolitan Provincial Rural Divisions with an area of less than 10 000 sq kms, and Divisions with a majority of electors within capital city statistical division, and Divisions containing areas of more recent urban expansion. Divisions with an area of less than 10 000 sq kms, and Divisions with a majority of electors outside capital city statistical division, and Divisions with a majority of electors in major provincial centres with a population of 50 000 or more. Divisions with an area of 10 000 sq kms or more, or Divisions with an area of less than 10 000 sq kms and not classified as Metropolitan or Provincial. All divisions of 10,000 square kilometres or more will be classified as rural, regardless of where the majority of their enrolment is located. The new geographic classification is simply a refinement to the existing classification structure. It is more rigorous and subject to less subjective judgement than the existing classification. Refining the definition will have a minimal impact on current classifications, as less than 15% of divisions will have their classification altered. It will however make classification decisions more accurate and ensure like divisions are categorised consistently. The use of area specific criteria will also assist in making more meaningful the classification of divisions such as the Northern Territory, where there are a number of contradictory indicators. A list of divisions whose geographic classification is proposed to change is at Attachment 2. Managing the Classification Process The AEC will continue assigning classification categories to electoral divisions. Classification decisions will only be made after consultation with the Australian Electoral Officer of the relevant State or Territory. There will be three categories of classification: • the existing classification according to party safeness; • geographic classification which, as outlined above will build on and clarify the existing socio-demographic classification; and • a new category based on socio-economic criteria and as outlined above. The allocation of electoral divisions to classification categories will be undertaken according to the following schedule: • geographic classification: after each redistribution in a State or Territory; • party safeness classification: after each House of Representatives election OR after each redistribution in a State or Territory; and • socio-economic classification: after each population census OR after each redistribution of a State or Territory. Attachment 3 lists of electoral divisions against the three categories of classification. The classification of divisions will be reviewed following a House of Representatives election, a population census or a redistribution. The results of this review will be promulgated through AEC publications and web media with a record of divisional classification to be kept on the Roll Management System (RMANS). The first review of electoral divisions against the three categories of party safeness, geographic criteria and socio-economic status will occur following the 2004 federal election. 5 Any comments?
