The table provides information about the population in the past, along with a projection for the future in Australia, Canada, New Zealand, and the USA, between 1990 and 2020, with forecasts to 2050.
Overall, all four states witnessed an upward trend in terms of their population figures. While the USA recorded the highest number as the most urbanized by far in all years, followed by Canada and Australia, New Zealand saw little change across the period, representing the least populated country.
The USA accounted for the most populous country in all the years, with 249.9 million residents in 1990; this figure continued increasing exponentially, reaching 320 million by 2020. It is forecast that this figure will be the highest by 2050, with 349 million dwellers. Canada’s population number increased consistently, starting at 26.6 and 28.5 million inhabitants initially, and it is anticipated to reach 39 million by 2050, a ten increase compared to other years. While the number of Australian inhabitants remained almost stable during 1990 and 1995, it then rose gradually, registering 22 million in 2020.
By contrast, New Zealand is the least urbanized among the three countries; its population count ranged between 3.4 and 3.8 million during 1990 and 2000. A modest growth is projected by 2050, with over 4 million citizens.
