The enrolment data provided by the Australian Electoral Commission (AEC) have been prepared for the information of persons and organisations interested in the redistribution of federal electoral boundaries in New South Wales.
For the purposes of the redistribution, the AEC has made available:
Enrolment as at 1 December 2014 is supplied as these figures were used for the Electoral Commissioner's determination of the current enrolment quota under section 65 of Commonwealth Electoral Act 1918 (the Electoral Act). In making a proposed redistribution, the Redistribution Committee and the augmented Electoral Commission are bound by the Electoral Act to ensure that the number of electors in each proposed electoral division does not deviate by more than 10 per cent above or below the current enrolment quota. The current enrolment quota for New South Wales was determined by the Electoral Commissioner to be 103 481 as at 1 December 2014.
Projected enrolment at 25 August 2019 is supplied because, as far as practicable, the Redistribution Committee and the augmented Electoral Commission are required to ensure that the number of electors enrolled in each division at 25 August 2019 (the projection time) will not deviate by more than 3.5 per cent above or below the projected enrolment quota.
A growth (%) figure is also provided. This is the estimated growth rate for the period December 2014 to August 2019. The growth rate shown for each SA1 is calculated by subtracting the actual enrolment from the projected enrolment, then dividing by the actual enrolment. The result is expressed as a percentage.
The following information is provided for each division in New South Wales:
Following a recommendation by the Joint Standing Committee on Electoral Matters (JSCEM) that the AEC and the Australian Bureau of Statistics (ABS) work together on enrolment projections, the ABS has supplied enrolment projections to the AEC using AEC enrolment data as the base. The ABS has used a cohort-component method to project the enrolment of each SA1. The methodology is detailed in the appendices included with this document.
Divisional Returning Officers (DROs) were asked to examine the ABS projections in the light of their local knowledge and experience, and to substitute their own projections where appropriate. The Australian Electoral Officer and State Manager for New South Wales also reviewed the projections to ensure a consistent approach.
Enrolment figures are provided at the SA1 level, as this level is the smallest commonly used geographic building block. The SA1 figures are aggregated to show the totals for SA2s, which are comprised of a number of SA1s. Being somewhat larger than SA1s, SA2s may be more manageable for those who are interested in less detailed analysis.
The figures shown are broken down according to electoral division. Where a SA1 or SA2 crosses divisional boundaries, the SA1 or SA2 concerned will be listed in each division in which electors are enrolled. Only those electors resident in that division are included in the figures for such SA1s or SA2s.
Data is provided in the following files:
Each file contains:
The existing federal boundaries for New South Wales are provided in a spatial format.
You will need GIS software to view and manipulate spatial data; however TAB files have been provided for those who do not have GIS software. To view the TAB files, you can download MapInfo ProViewer software which is a free MapInfo viewer from Pitney Bowes.
Access to a computer with the software program, Electoral Boundary Mapping System (EBMS), which runs within the commercial software program MapInfo, will be made available for interested persons at the office of the Redistribution Committee for New South Wales in Sydney.
Bookings will be required and can be made by telephoning the NSW Redistributions Secretariat 02 9375 6317 during business hours (9am to 5pm). Some knowledge of the systems will be assumed and only a brief introduction can be offered. Access to this system will be available during the periods allowed for suggestions, comments on suggestions, objections and comments on objections.
