 Australia's population has quadrupled since the end of World War I, much of this increase from immigration. Following World War II and through to 2000, almost 5.9 million of the total population settled in the country as new immigrants, meaning that nearly two out of every seven Australians were born in another country. Most immigrants are skilled, but the immigration quota includes categories for family members and refugees. By 2050, Australia's population is currently projected to reach around 42 million. Nevertheless, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. As such, Australians have more living space per person than the inhabitants of any other nation.
