Australia is a major immigration destination. Approximately a quarter of its 20 million people were born outside of the country.
Their countries of origin are diverse and include the UK, China, Italy, Greece, India, Sri Lanka, Vietnam, Malaysia, South Africa and many more others.
Although the fertility rate sits at 1.76 children per female, this is still well below the rate required. Australia’s population is ageing rapidly, with the median age being 36 years and rising.
Therefore, much of this nation's population growth is due to immigration. This is expected to continue to be the case throughout the 21st century.
