COMPONENTS OF POPULATION CHANGE
Persons aged under 15 years comprised 19% of the South Australian population at 30 June 2002 compared with 21% at 30 June 1992. Over this ten-year period, persons aged 65 years and over increased from 13% to 15% of the population, while the proportion of persons aged 85 years and over increased from 1.1% to 1.7%. At 30 June 2002, females comprised 56% of persons aged 65 years and over and 69% of persons aged 85 years and over.
POPULATION, South Australia, 31 December
BIRTHS AND CONFINEMENTS
In 2002 there were 17,400 confinements resulting in 17,700 live births registered to mothers usually resident in South Australia. Registrations of births were 2% higher than in 2001 (17,300 births) and 9% lower than in 1992 (19,300 births). There were 9,100 male and 8,600 female births registered in 2002, giving a sex ratio of 105.1 males per 100 females. South Australia had the lowest crude birth rate in Australia, with 11.6 births per 1,000 population.
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 1.72 babies per woman in 2002. Since 1975, TFRs have been below the rate of 2.1 babies per woman, which is the rate required for replacement of the population.
A baby girl born in 2002 can expect to have 0.83 daughters in her life time. This is the net reproduction rate and takes into account the current fertility rates, the sex ratio of babies, and the chance of her dying before finishing her reproductive life.
The upward trend in median ages of parents at confinement continued in 2002, to a high of 30.4 years for mothers and 32.6 years for fathers, reflecting the tendency for couples having children later in life. The 30-34 year age group had the highest fertility rate for the fourth consecutive year and was 111.2 babies per 1,000 women in 2002.
AGE-SPECIFIC FERTILITY RATES
(a) Births per 1,000 women
Indigenous births are defined as births in which one or both parents identified as being of Aboriginal or Torres Strait Islander origin. There were 680 Indigenous births registered to parents who were usually resident in South Australia in 2002 and 560 Indigenous births in 1992. These births comprised 4% of all South Australian births, compared with 3% in 1992.
BIRTHS AND CONFINEMENTS(a), South Australia
In 2002 there were 12,000 registered deaths of persons usually resident in South Australia, an increase of 10% from 1992 when there were 10,900 deaths. The increase in the number of deaths over time reflects the increasing size of the population and in particular, the increasing number of older people. In 2002, there were 6,100 male deaths and 5,900 female deaths.
The crude death rate (CDR) was 7.9 deaths per 1,000 population in 2002. There has been little movement in CDRs over the last 10 years. However, a fall in death rates is observed when the rates are standardised to eliminate the effect of the changing age structure of the population over time. The standardised death rates (SDR) have fallen from 7.9 deaths per 1,000 standard population in 1992 to 6.7 deaths per 1,000 standard population in 2002.
The CDRs for males have been slightly higher than those for females in the last decade even though the male population has a younger age structure than the female population. In 2002 there were 8.1 male deaths per 1,000 males in the population compared with 7.7 female deaths per 1,000 females in the population. SDRs show that there are significant differences between the mortality experiences of the sexes. In 1992, the male SDR was 10.2 deaths per 1,000 standard population, 62% higher than the female SDR of 6.3 deaths per 1,000 standard population. In 2002, the male SDR was 8.3 deaths per 1,000 standard population, 54% higher than the female SDR of 5.4 deaths per 1,000 standard population.
(a) Deaths per 1,000 population
In 2002, the main underlying causes of death were malignant neoplasms (3,300 deaths) and ischaemic heart diseases (2,400 deaths). The standardised death rate for malignant neoplasms was 189 deaths per 100,000 standard population in 2002 compared with 194 deaths per 100,000 standard population in 1992 representing a decrease of 3%. Ischaemic heart diseases were the leading underlying cause of death in 1992 but have been second to malignant neoplasms since then. Over the last decade, there was a large decrease (39%) in SDRs for ischaemic heart diseases, from 212 deaths per 100,000 standard population in 1992 to 129 deaths per 100,000 standard population in 2002.
The infant mortality rate was 5.1 infant deaths per 1,000 live births in 2002.
DEATHS(a), South Australia
In 2002, more people migrated to South Australia than left for interstate or overseas. There were 14,100 persons who arrived from overseas with the intention of staying for at least 12 months or more and 9,700 persons who departed from South Australia with the intention of staying abroad for at least 12 months. Of the 30,100 persons who changed their usual residence from interstate to South Australia (arrivals), 8,100 persons (27%) came from Victoria and 7,700 persons (26%) from New South Wales. Of the 31,600 persons who changed their usual residence from South Australia to another state or territory (departures), 9,200 persons (29%) moved to Victoria and 7,700 persons (24%) moved to Queensland. South Australia's largest net gain was from New South Wales (900 persons) and largest net losses were to Queensland (1,900 persons) followed by Victoria (1,100 persons).
INTERSTATE MIGRATION, 2002
MIGRATION, South Australia
In 2002, there were 7,400 marriages registered in South Australia and at least one of the parties had been previously married in 2,700 (36%) of them. Ministers of religion performed 3,400 marriages (47%) and 5,400 couples (74%) cohabited prior to their marriages. The crude marriage rate was 4.9 marriages per 1,000 persons residing in South Australia.
MARRIAGES, South Australia
Details on divorces are not yet available for 2002. In 2001, there were 4,500 divorces granted in South Australia and the crude divorce rate was 3.0 divorces per 1,000 population.
DIVORCES, South Australia
The Adelaide Statistical Division (ASD), which contained 73% of the South Australian population, had 72% of the State's births and 73% of the State's deaths in 2002. The ASD's average total fertility rate over the three years 2000-2002 (1.62 births per woman) was less than the three-year average for the remainder of the State (2.05 births per woman).
At 30 June 2002, the most populous Statistical Local Area (SLA) within South Australia was Onkaparinga (C) - Woodcroft, which had an estimated resident population of 35,100. Next came Salisbury (C) - South-East (34,600 persons), Marion (C) - Central (33,300 persons), Tea Tree Gully (C) - South (33,300 persons) and Charles Sturt (C) - Coastal (31,400 persons). Mount Gambier (C) (23,500 persons) was the 24th most populous SLA within the state and it was the most populous SLA outside the ASD.
