Students learn about:Human characteristics that make Australia unique • demographic characteristics: • age structure • distribution • ethnic composition • Gender • growth rates • population size
Students learn to: • describe past and current population patterns in Australia • describe trends in Australia’s demographic characteristics, incorporating the use of graphs and statistics • explain how Australia’s changing demographic characteristics are influencing the nature and identity of Australian society
Australia’s population • Demography is the study of the characteristics of populations. It analyses: • population size • population composition • population growth • population distribution • population density • sex structure • age structure • all other vital statistics related to the characteristics of a particular population.
Australian population size • http://www.abs.gov.au/ausstats/abs%40.nsf/94713ad445ff1425ca25682000192af2/1647509ef7e25faaca2568a900154b63?OpenDocument
Population increase • Australia’s population is currently growing at its fastest rate in almost 20 yrs with the most recent increase of 1.5% or 318,500 people to September 2007 • Net migration for last year 2008 was 213,000. • But skilled migration has been cut in 2009 from 133,000 to 115,000 • Every 3 years Australia is approximately adding 1 million to its population • 2008 320,000 was added to the population (a combination of natural increase and immigration)
Outline how each component of Australia’s population has changed over time: Refer to the graph below
Answer • (i) natural increase: • Natural increase was highest in the early 1900’s. • Dropped sharply with WWI and was also low during the Great Depression and WWII • Increased after WWII (Baby Boomers) • Has been declining since the 1970’s
Answer • migration: • Increased sharply from 1905 but fell sharply with WWI and was also low during the Great Depression and WWII • Rapid increase post WWII • Has continued to remain an important component (with some fluctuations in recent decades).
Population Distribution & Density • This figure shows the uneven distribution of the Australian population. • 80% of peoplelivein a narrow coastalstrip stretching from Brisbane to Adelaide. • This represents only 3% of the continentsland area.
A zone of moderate population density stretches from the Darling Downs in Southern Queensland through the central west of NSW and across to Victoria. • The remaining 81% of the continent contains just 3% of the population.
Each of these zones is associated with different land uses. • The closely settled coastal strip contains almost all the major urban centres and most of the large-scale industry and business. • The moderately settled zone is dominated by agriculture and some small-scale industry. • The sparsely settled zone is dominated by extensive grazing and scattered mining activities. Australia’s population density (that is the number of people per square kilometre) is 2 people per square kilometre. • This is the lowest of any of the continents, except for Antarctica.
The distribution of Australia’s population is undergoing change. • The most important of these changes are: The proportion of the population living in rural areas is declining. As a result many small rural communities are struggling to survive. The proportion of people living in the Northern Territory, WA & QLD has increased, while the proportion living in NSW, VIC, SA & TAS, has declined There are regional variations in population growth rates. During the 1950/60s the fastest growing areas were the state capitals.

Population growth • Figure 5.1a on pg 126 of the text shows the contribution made by the two components of population growth: natural increase and net migration Draw figure 5.1a into your books • NATURAL INCREASE- is the difference between the birth rate(which is expressed as the number of live births per thousand of the population per year) and the death rate(the number of deaths per thousand people per year). • NET MIGRATION- is the difference between the number of permanent departures from Australia and the number of people arriving to live in Australiaon a permanent basis.
Net Migration • Net migration is the difference between the number of permanent departures from Australia (emigration) and the number of people arriving to live in Australia on a permanent basis (immigration) • permanent arrivals (immigration) – permanent departures (emigration) = net migration
Australian Population Change 1901-2002 Growth rates
I’ve lost my job. I can barely support my wife and me, let alone kids. My husband is away fighting in Europe. Some of my friends’ husbands have been killed. We need workers to build the Snowy Mountains Scheme I was born just after the war, and now I’m having a family myself I have a great job. I would ruin it by having kids now. We were nearly invaded in the war. We need more people to defend Australia I have a good job and I’m earning a good wage. I could support a larger family.
A significant share of Australia’s population growth has come from immigration. (To enter and settle in a country or region to which one is not native.) • Since World War II (1939- 1945) more than 5 million people have migrated to Australia. • The outcome of this process has been the development of a multicultural society. • At present one in every four Australians is either a first generation or second generation settler. • The source of these immigrants has changed overtime.

Population Structure • The age/ gender structure of the Australian population resembles that of other developed countries. i.e. a narrowing base and an expansion in the older age groups. Explain why? This change is the result of the ageing of the population.

Reasons for the ageing population- Declining birth rates- Lower fertility rates have resulted in a decrease in the proportion of young people in the population Increasing Life expectancy * Australians are living longer * Life expectancy for: -83 years • 77 years Changes in Australia’s immigration program In the 1950s/60s there was a large scale immigration program. Majority of immigrants were young. Many of them had children. Late 1980/90s, the immigration program was significantly reduced & many of those who did arrive were older.
Fertility • The total fertility rate (TFR, of a population is the average number of children that would be born to a woman over her lifetime • The total fertility rate (TFR) is a measure of current fertility. Australia's TFR dropped below replacement level (2.1 babies per woman) in 1976. • It has remained below replacement level and declined further since then until recently. • This means that under current age-specific fertility rates the average number of babies born to a woman throughout her reproductive life would not be sufficient to replace herself and her partner. • http://www.radioblogclub.com/open/128196/we_are_family_sister_sledge/Sister_Sledge_-_We_Are_Family
Fertility • In 2001, Australia's fertility reached a historic low of 1.73 babies per woman. Since then, the total fertility rate has increased to 1.83 in 2007 and in 2008 increased to 1.93. • Additionally, women in more advantaged areas, while having fewer babies than those in less advantaged areas, have had the greatest increase in fertility between 2001 and 2007.
Account for the low fertility rate: DELAYING CHILDBIRTH • Increased status of women due to higher levels of tertiary (University education) has meant that women are delaying childbirth because they are staying in the workforce longer • Increased use of contraception • Increase in cost of living
Median age for mothers & fathers • The trend towards delaying child-bearing in Australia is evident in the median age of parents. • For both mothers and fathers, median age has risen consistently over the past two decades. • In 1983, the median age of all mothers who gave birth in that year was 26.9 years, while the median age of fathers was 29.7 years. • In 2003, the median ages were 30.5 years and 32.6 years for mothers and fathers respectively.

Government response • With the fertility rate plummeting to record lows the Australian Government in recent times has offered a Baby Bonus • In 2004 Peter Costello in his budget address famously said • "You should have one for the father, one for the mother and one for the country. If you want to fix the ageing demographic, that's what you do,"
