This is the final issue of this electronic product. It is intended that future state and territory-specific data will be made available in spreadsheet format with releases of the relevant annual national publications.

This electronic product provides a demographic overview of Western Australia, 2004. It contains summary tables and commentary on trends in the components of population change including births, deaths and migration. Marriages, divorces, estimated resident population and various demographic rates are also presented. Population and migration data are for the year ended 30 June 2004, while births, deaths, marriages and divorces data are for the year ended 31 December 2004. More recent data are released quarterly in Australian Demographic Statistics (cat. no. 3101.0).

SUMMARY COMMENTARY


OVERVIEW

At 30 June 2004, Western Australia's population was 1,978,000 which was 9.8% of the Australian population. Western Australia has been the fourth most populous state since 1982. The state had 9.9% of all births, 8.4% of all deaths, 9.6% of all marriages and 8.2% of all divorces in Australia in 2004. Of all overseas arrivals (permanent and long-term), 11.5% settled in Western Australia. The state also recorded a net gain through interstate migration for the first time since 1999.



POPULATION

The Estimated Resident Population of Western Australia at 30 June 2004 was 1,978,000, which was 9.8% of the Australian total. The main contributors to population growth in 2004 were net overseas migration (13,600) and natural increase (13,200). Net overseas migration has been the largest source of annual population growth in Western Australia since 2000. During the year to 30 June 2004, Western Australia also experienced a net gain of 1,300 persons through interstate migration. Western Australia remained the second fastest growing state/territory in 2003-04, with a growth rate of 1.4%. Queensland had the highest growth rate of 2.3%.

BIRTHS AND CONFINEMENTS

In 2004, there were 24,900 confinements resulting in 25,300 births registered to mothers usually residing in Western Australia. Registrations of births during 2004 were 4.2% higher than in 2003 (24,300 births) and 0.6% higher than in 1994 (25,100 births). There were 13,000 male births and 12,300 female births registered in 2004, giving a sex ratio of 105.2 males per 100 females. The crude birth rate for Western Australia was 12.8 births per 1,000 estimated resident population, which was slightly higher than the national rate of 12.7.


The total fertility rate (TFR), the average number of babies that a woman could expect to give birth to in her lifetime if she experienced current age-specific fertility rates, was 1.81 babies per woman in 2004. Since 1977, TFRs have been below the rate of 2.10 babies per woman, which is the rate required for replacement of the population.


The tendency to have children later in life continued. While the upward trend in median age of mothers stabilised in 2004 remaining 30.2 years, there was an increase for fathers to a high of 32.6 years. The 30-34 year age group had the highest fertility rate at 114.4 babies per 1,000 women in 2004.

DEATHS

In 2004, there were 11,200 registered deaths of persons usually resident in Western Australia, an increase of 8.7% from 1994 when there were 10,300 deaths. There were 5,900 male deaths and 5,300 female deaths. Despite the ageing of the population, there has been a slight decline in the crude death rate over the last 10 years. The crude death rate (CDR) was 5.7 deaths per 1,000 estimated resident population in 2004, compared with 6.0 in 1994. Western Australia's CDR was lower than the national rate of 6.6. In 2004, the CDR for males (5.9) was slightly higher than for females (5.4) and has been over the previous decade.


Standardised death rates (SDRs) enable comparison of death rates between populations with different age structures. In 2004, Western Australia's SDR of 6.0 was lower than the national rate of 6.3, with only the Australian Capital Territory recording a lower SDR (5.6). In 2004, the male SDR was 7.3 and the female SDR significantly lower at 4.9.


In 2004, life expectancy at birth for Western Australian usual residents was 78.6 years for males and 83.3 years for females, slightly above the national averages of 78.1 and 83.0 years respectively. Compared with ten years ago, life expectancy at birth in Western Australia has increased by 3.1 years for males and 2.1 years for females.

MIGRATION

Overseas migration includes permanent and long-term (over 12 months) movement between Australia and other countries. Net overseas migration refers to net permanent and long-term overseas migration, adjusted for changes in traveller duration intention and errors associated with multiple movements during long-term stays or absences. In 2004, net overseas migration contributed an additional 13,600 persons to the Western Australian population, 2,000 less than in 2003 but more than double in 1994 (6,700).


Western Australia's net interstate migration has fluctuated over the past 20 years, peaking at 9,400 in 1986 and declining to a net loss of 4,400 in 2002. In 2004, Western Australia recorded a net gain from interstate migration of 1,300 people, the first increase since 1999. There was a net gain of 1,700 people from New South Wales, 600 people from South Australia and 360 people from the Northern Territory and net losses to all other states and territories during the year. Queensland was the most popular destination followed by Victoria.

MARRIAGES

In 2004, there were 10,600 marriages registered in Western Australia, this was 11.0% higher than the number registered in the previous year. This is the highest number of marriages recorded in a year since 2000 when 11,000 were registered. The crude marriage rate (the number of marriages per 1,000 of the estimated resident population) for Western Australia was 5.4 in 2004, this compares with a national rate of 5.5.


The median age for brides in 2004 was 29.6 years and for bridegrooms it was 31.9 years. This compares with median ages of 26.9 years and 29.5 for brides and bridegrooms respectively in 1994 and reflects the continuing tendency to marry later in life.

Duration of marriage is the interval between the date of marriage and the date the divorce was made absolute. In 2004, the median duration of marriage in Western Australia was 12.8 years, 1.4 years longer than in 1994 but slightly lower than the peak of 13.2 years in 2003.

REGIONAL SUMMARY

In 2004, the Perth Statistical Division accounted for 73.5% of the Western Australian population and had 71.7% of the State's births and 73.5% of the State's deaths. The Perth Statistical Division's average total fertility rate over the three years 2002-2004 (1.67 births per woman) was less than the three-year average for the remainder of the State (2.04 births per woman).


In Western Australia, the largest populations tended to be in those Statistical Local Areas (SLAs) on the fringe of the Perth Statistical Division. The most populous SLA in Western Australia was Joondalup - South with an estimated resident population of 107,000 persons. Other SLAs within the Perth Statistical Division with high populations were Stirling - Central (101,000), Melville (97,300), Swan (91,500), Gosnells (89,900), Rockingham (81,700), Canning (79,400), Cockburn (74,500), and Stirling - Coastal (64,100).


The largest SLA outside the Perth Statistical Division was Mandurah with a population of 58,500 persons.
