SUMMARY

In 2002, Western Australia's population was 1.937 million which was 9.8% of the Australian population. Western Australian has been the fourth most populous state since 1982. Western Australia had 9% of all births in Australia, 8% of all deaths and 10% of all marriages. In 2002, Western Australia recorded its fourth consecutive year of net loss through interstate migration. 11% of all overseas arrivals settled in Western Australia.

POPULATION

The Estimated Resident Population of Western Australia at 31 December 2002 was 1.937 million, which was 9.8% of the Australian total. The main contributors to population growth in 2002 were net overseas migration (15, 600) and natural increase (12, 300). Western Australia also experienced a loss of 4, 200 persons through interstate migration. Western Australia was the second fastest growing state/territory in 2002, with a growth rate of 1.2%, the same as the growth rate for Australia. Queensland had the highest growth rate of 2.3%

Net overseas migration has been the main source of population growth since 2000.

BIRTHS AND CONFINEMENTS

In 2002, there were 23,200 confinements resulting in 23,600 births registered to mothers usually residing in Western Australia. Registrations of births were 3% lower than in 2001 (24, 000 births) and 6% lower than in 1992 (25,100 births). There were 12,100 male births and 11,500 female births registered in 2002, giving a sex ratio of 105.2 males per 100 females. The crude birth rate for Western Australia was 12.3 births per 1,000 estimated resident population, which was lower than the national rate of 12.8. Western Australia had the second lowest crude birth rate, with South Australia having the lowest at 11.6.

The total fertility rate (TFR), that is 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 1.688 babies per woman in 2002. Since 1975, TFR's have been below the rate of 2.1 babies per woman, which is the rate required for replacement of the population.

The upward trend in median age of parents continued in 2002, to a high of 29.9 years for mothers and 32.2 years for fathers, reflecting the tendency for couples having children later in life. The 30-34 year age group had the highest fertility rate at 105.6 babies per 1,000 women in 2002.

DEATHS

In 2002, there were 11,300 registered deaths for persons usually resident in Western Australia, an increase of 14% from 1992 when there were 9,900 deaths. There were 5,800 male deaths and 5,500 female deaths. Despite the ageing of the population, there has been little movement in the crude death rates over the last 10 years. The crude death rate (CDR) was 5.9 deaths per 1,000 estimated resident population in 2002, compared with 6.0 in 1992. Western Australia's CDR was lower than the national rate of 6.8. The CDR for males (6.1) has been slightly higher than that for females (5.7) in the last decade, even though the male population has a younger age structure than the female population.

Standardised death rates (SDRs) enable comparison of death rates between populations with different age structures. Western Australia's SDR of 6.4 was lower that the national rate of 6.7, with only the Australian Capital Territory recording a lower SDR (5.9). In 2002, the male SDR was 7.8 and the female SDR was significantly lower at 5.3.

MIGRATION

In 2002, net overseas migration contributed an additional 15,600 persons to the Western Australian population, 750 less than in 2001. Net interstate migration has been falling since 1996 and since 1999 the number of persons leaving Western Australia has exceeded the numbers coming into Western Australia. In 2002, the net loss through interstate migration was 4,200 persons.

Overseas migration includes permanent and long-term (over 12 months) movement between Australia and other countries. Net overseas migration refers to the 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.

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 4,200 in 2002. Despite the long-term trend of moderate net interstate gains, Western Australia has, over the past 4 years, experienced a net loss in interstate migration, with the largest net loss of 4,400 persons being experienced in 2001. Net interstate migration losses were also recorded during 1991, 1992 and 1993, although not to the same magnitude as in the past four years.

MARRIAGES

In 2002, there were 10, 500 marriages registered in Western Australia which was 7.1% higher than the number registered in 2001. However, this number was still lower than the 11,000 marriages registered in 2000, which was the highest figure ever recorded. The crude marriage rate (the number of marriages per 1,000 of the estimated resident population) for Western Australia was 5.4 in 2002, which was the same as the national rate.

Among people marrying for the first time in 2002, the median age for bridegrooms was 29.5 years and 27.3 years for brides. In 1992, the median ages were 27.0 years and 24.7 years respectively and reflects a continuing tendency to marry later in life. In 2002, the median age for all brides was 29.3 years and all bridegrooms was 31.6 years.

DIVORCES

Details on divorces are not yet available for 2002. In 2001, there were 5,351 divorces granted in Western Australia and the crude divorce rate was 2.8 divorces per 1,000 population. This rate is slightly lower than the national crude divorce rate of 2.9. Over the last 10 years, the crude divorce rate has remained fairly stable with a low of 2.7 in 1992 and a high of 2.9 in 1999.

Duration of marriage is the interval between the date of marriage and the date the divorce was made absolute. In 2001, the median duration of marriage in Western Australia was 12.6 years. This is the highest median duration of marriage since the passage of the Family Law Act 1975.

REGIONAL SUMMARY

The Perth Statistical Division, which contained 73% of the Western Australian population, had 71% of the State's births and 73% of the State's deaths in 2002. The Perth Statistical Division's average total fertility rate over the three years 2000-2002 (1.65 births per woman) was less than the three-year average for the remainder of the State (2.05 births per woman).

In Western Australia, the largest populations tended to be in those SLAs on the fringe of the Perth Statistical Division. The most populous Statistical Local Areas (SLAs) in Western Australia was Joondalup (C) - South with an estimated resident population of 107,500 persons. Other SLAs within the Perth Statistical Division with high populations were Stirling (C) - Coastal (62,500), Cockburn (C) (71,200), Rockingham (C) (76,200), Canning (C) (78,100), Gosnells (C) (85,100), Swan (C) (87,300), Melville (C) (97,200), Stirling (C) - Central (99,100). The largest SLA outside the Perth Statistical Division was Mandurah (C), which was the twelfth largest SLA in Western Australia, with a population of 50,800 persons.
