Introduction

The Parliamentary Library has obtained from the Australian Bureau of Statistics (ABS) unpublished 2007 and 2006 data on the Estimated Resident Population (ERP) of Commonwealth electoral divisions (or seats) based on 2007 electoral boundaries. This allows analysis of various aspects of population change for divisions over the period 2006 to 2007 on a consistent conceptual and geographic basis. The 2007 ERP figures are preliminary and subject to revision. The 2006 ERP figures contain revisions to data previously supplied to the Parliamentary Library and are now final estimates.

ERP estimates are the official estimates of the Australian population and they link people to a place of usual residence within Australia. ERP data are based on census counts by place of usual residence to which are added the estimated net census undercount and Australian residents estimated to be temporarily living overseas. ERP figures also have the added advantage over census figures of being available on a quarterly or annual basis and are available as time series on a consistent basis.

The source 2007 and 2006 ERP electoral division data by single year of age and sex, as supplied by the ABS, are available from the Electorate Atlas resource on the Parliamentary Library’s intranet (available only to Senators and Members) together with 2001 ERP data previously supplied by the ABS. An analysis of summary data for the total population, the 0 to 4 years age group, the 5 to 14 years age group, and the 65 and over age group are presented in the following tables.

Main features

A brief description of the contents of each table is given below together with a summary of some of the more interesting features of the data.

Table 1: Total population

Table 1a: Estimated Resident Population, 2006 and 2007

Table 1b: Divisions ranked by total population growth, 2006 to 2007

Table 1a shows the total ERP in 2007 and 2006 as well as the population change and growth rate for all electoral divisions. The data are displayed in alphabetic order of electoral divisions. Table 1b shows the same data as in Table 1a with the data ranked by the population growth rate.

The division with the lowest total population in 2007 is Lyons (96 819). It also had the lowest population in 2006. The seven divisions with the lowest populations comprise all the divisions in Tasmania and the Northern Territory. Tasmania retains five electoral divisions due to the Constitutional provision that guarantees a minimum of five seats in the House of Representatives for each ‘Original State’. The calculation of representation entitlement that last occurred in November 2005 resulted in the Northern Territory having a quota of just over 1.5 resulting in an entitlement of two seats. As a result the two divisions in the Northern Territory have relatively small populations. The division with the highest population in 2007 is Reid (175 194), followed by Holt (173 056) and Lalor (171 325). 

The Australian population grew by an average 1.5 per cent between 2006 and 2007. At the electorate level, Fadden (5.8 per cent) was the fastest growing electoral division, followed by Pearce (5.2 per cent) and Lalor (5.0 per cent). There are five electoral divisions that declined in size and four of these are in New South Wales. The electoral division with the lowest growth rate was Parkes (-0.5 per cent) followed by Maribyrnong in Victoria (-0.3 per cent).

Table 2: Population aged 0 to 4 years

Table 2a: Estimated Resident Population aged 0 to 4 years, 2006 and 2007

Table 2b: Divisions ranked by growth rate in 0 to 4 years age group, 2006 to 2007

Table 2a shows the ERP in the 0 to 4 years age group in 2007 and 2006 as well as this age group’s population change and growth rate for all electoral divisions. The data are displayed in alphabetic order of electoral divisions. Table 2b shows the same data as in Table 2a with the data ranked by the 0 to 4 years age group population growth rate.

The Australian population aged 0 to 4 years increased by 1.8 per cent from 2006 to 2007, which was higher than the 1.5 per cent growth rate of the total population. There were significant variations in the growth rate for individual electoral divisions with the highest growth rate occurring in Brand (8.8 per cent) followed by Sydney (8.5 per cent) and Wentworth (7.7 per cent). Thirty four electoral divisions experienced a decline in the 0 to 4 years age group: the largest percentage decline occurred in Parkes (-2.3 per cent), followed by Fowler (-2.2 per cent) and Macquarie (-2.0 per cent).

Table 3: Population aged 5 to 14 years

Table 3a: Estimated Resident Population aged 5 to 14 years, 2006 and 2007

Table 3b: Divisions ranked by growth rate in 5 to 14 years age group, 2006 to 2007

Table 3a shows the ERP aged 5 to 14 years in 2007 and 2006 as well as this age group’s population change and growth rate for all electoral divisions. The data are displayed in alphabetic order of electoral divisions. Table 3b shows the same data as in Table 3a with the data ranked by the 5 to 14 years age group population growth rate.

The Australian population aged 5 to 14 years increased by just 0.1 per cent between 2006 and 2007, which was significantly lower than the 1.5 per cent growth rate of the total population. There were significant variations in the growth rate for individual electoral divisions with the highest growth rate occurring in Fadden (5.7 per cent) followed by Pearce (3.9 per cent) and Oxley (3.1 per cent). There were 76 electoral divisions that experienced a decline in the 5 to 14 years age group. The largest percentage decline occurred in Gilmore (-2.5 per cent), followed by Parkes (-2.4 per cent) and Canberra (-2.4 per cent).

Table 4a: Estimated Resident Population aged 65 years and over, 2006 and 2007

Table 4b: Divisions ranked by growth rate in 65 years and over age group, 2006 to 2007

Table 4a shows the Estimated Resident Population aged 65 years and over in 2007 and 2006 as well as this age group’s population change and growth rate for all electoral divisions. The data are displayed in alphabetic order of electoral divisions. Table 4b shows the same data as in Table 4a with the data ranked by growth rate of the 65 and over age group.

The Australian population aged 65 years and over increased by 2.7 per cent from 2006 to 2007, nearly double the growth rate of the total population. At the electoral division level, the highest growth rate occurred in Solomon (8.9 per cent) followed by Lingiari (7.6 per cent) and Lalor (6.6 per cent). There are only two electoral divisions that experienced a decline in the aged population over this period, Lilley (-0.7 per cent) and Wills (-0.4 per cent).
