Canada vs Australia, explained
Today Canada is the larger of the two, with about 40.3 million people against Australia's 27.1 million. Canada is the world's 38th most populous country and Australia the 55th.
Their paths to 2100 differ. Canada keeps growing over the century, moving from about 39.5 million to 53.5 million (+35.4%). Australia grows strongly, going from 26.6 million to 43.0 million (+61.9%).
The order does not flip this century: Canada is still the larger of the two in 2100. The two trajectories run in parallel rather than crossing.
The deeper contrast is age and fertility. Canada has a median age near 40 and 1.34 births per woman, against Australia's 38 and 1.64. All figures follow the UN's medium-variant projection.
