On 11 February 2018, the resident population of Australia was estimated to be 24,826,764.  Australia is one of the least densely populated countries in the world. This is due to its small population and its large area of approximately 7.7 million square kilometres. Australians are among the most urbanized people in the world. For example, just over 60% of them live in the capital cities and about 20% live in Sydney. Also, around 80% of the inhabitants of each state and territory live within 100 km of their capital cities.
