Enrolment projections - NT federal redistribution

Updated: 3 February 2016

Projected enrolment quota

The projected enrolment quota is calculated by dividing the projected number of people enrolled in the Northern Territory at the projection time by the number of members to which the Northern Territory is entitled
Estimated total number of electors enrolled in the Northern Territory at the projection time (7 August 2020) 141 376
Number of members of the House of Representatives to which the Northern Territory is entitled 2
Projected enrolment quota for the Northern Territory 70 688
Permissible maximum number of electors in an electoral division at the projection time (projected enrolment quota + 3.5%) 73 162
Permissible minimum number of electors in an electoral division at the projection time (projected enrolment quota – 3.5%) 68 214

Maps are available that depict current and projected enrolment per electoral division.

Enrolment projections for the Northern Territory: by electoral division, SA2 and SA1

Enrolment projections and enrolment as at 15 October 2015 for each division in the Northern Territory by Statistical Area 2 (SA2) and Statistical Area 1 (SA1). The percentage growth is also indicated.

Please note the Statistical Area Level 2 (SA2) is an area defined in the Australian Statistical Geography Standard (ASGS), and consists of one or more whole Statistical Areas Level 1 (SA1s). Wherever possible SA2s are based on officially gazetted State/Territory suburbs and localities. In urban areas SA2s largely conform to whole suburbs and combinations of whole suburbs, while in rural areas they define functional zones of social and economic links. Geography is also taken into account in SA2 design.

Appendix 1: NT small area population projections

This appendix, provided by the Australian Bureau of Statistics, outlines the process used for producing population and enrolment projections for all Statistical Area 1s (SA1s) in the Northern Territory, from June 2014 to June 2024.

Appendix 2: Projection methods for the NT, Statistical Area 2s (SA2s) and Statistical Area 1s (SA1s) – more details

This appendix, provided by the Australian Bureau of Statistics, gives a more detailed breakdown of the three tiered approach outlined in Appendix 1. The report outlines projection methods for the Northern Territory, Statistical Area 2s (SA2s) and Statistical Area 1s (SA1s).

Appendix 3: Conversion of Australian Bureau of Statistics (ABS) Population Projections to Enrolment Projections

This appendix, provided by the Australian Bureau of Statistics, outlines the process used to calculate enrolment projections for each Statistical Area Level 1 (SA1).

Differences between federal and state/territory electoral rolls

There is a federal electoral roll and an electoral roll for each state and territory. This is because each jurisdiction in Australia has their own electoral legislation, with electors subject to both federal and state/territory legislative requirements which may differ. It is these legislative differences which cause roll divergence. The causes of roll divergence can be categorised into two types:

  • divergence caused by differences in qualifications and disqualifications for enrolment and voting, and
  • divergence caused by differences in the process undertaken to enrol and maintain the currency of enrolment details.

Either type of divergence may result in an elector being enrolled for electoral events at one government level but not the other, or enrolled at different addresses for different levels of government.
