Is Australia really empty?

Australia has about 9 people per square mile, one of the lowest averages of any country. But that average describes a place almost no Australian lives. Most of them live somewhere very crowded.

An average spreads the people evenly over the land, but people don't spread out evenly. Australia's 9 people per square mile counts the empty outback as if people lived there. Ask instead how crowded it is where the typical Australian lives, and the answer is over 5,000 per square mile.

An average can describe a place where almost no one is. Before trusting one, ask what it was averaged over.

How we counted. The Australian Bureau of Statistics splits the whole country into squares 1 kilometer on a side (about 0.39 sq mi each) and estimates how many people live in each one. Each square is sorted by how crowded it is, then its land and its people are added to that group. "The typical Australian" is the median: half of all Australians live in squares at least that crowded. Weighting every square by its number of residents gives a similar answer, about 6,200 people per sq mi (2,400 per km²). The grid is modeled from mid-2024 population estimates, so small squares can be off, but the overall pattern is not.
