Followed by the statistics for Canada at 26.6, those of Australia at 17.1, and New Zealand at 3.4 in 1990. Similarly, in 2050, the United States is estimated to continue to hold the first rank in population at 349.0, followed by Canada, which will grow to 39.0 in population figures; Australia will rise by 8.9 units compared with the first year.
