**Response to @TrungTPhan:**

Australia has a similarly interesting map: 50% of the country's population lives in these three major centres (Melbourne, Sydney, Brisbane).

In fact, Australia's population (3.4 people per Km²) is among the world's lowest and less dense than Canada (4 people per Km²).
