Australian Demographic Trends
In 1901, the Australian government had a plan to make Australia’s population all white to prevent Australia from losing its heritage. In 1973 the “white Australia” law was abandoned, this causing the share of many non-European immigrants entering Australia .After world war II, the population of the Aborigines rapidly increased and 600,000 refugees from countries all over the world had arrived into Australia. About half of Australia’s population has been born overseas or has atleast 1 parent born overseas. At the start of the 21st century a little bit over 1/3 of Sydney and Melbourne’s population were born in countries other than Australia.
When the “white Australia” law was abandoned Australia’s population increased by less than half the worlds average, however Australia’s death and birth rates are also far less than the world average. Most men living in Australia are expected to live to the age of 75, while most women in Australia are expected to live to the age of 80. Approximately 1/5 of Australia’s population is under 15.
