The table presents a comparative analysis of historical and projected population figures (in millions) for four countries: Australia, Canada, New Zealand, and the United States, across various years.
Overall, the data highlights that the United States consistently maintains the largest population, while New Zealand exhibits the slowest growth rate among the nations analyzed.
Focusing on Australia, the population increased from 17.1 million in 1990 to 17.7 million in 1993. By 2000, this figure rose to 19.2 million and reached 22.7 million in 2020. Projections indicate that by 2050, Australia’s population is anticipated to rise to 26.0 million. In contrast, Canada, which recorded a population of 26.6 million in 1990, is expected to grow significantly, reaching approximately 39.0 million by 2050, following a steady increase that brought its population to 36.9 million in 2020.
In New Zealand, the population has consistently been the lowest, starting at only 3.4 million in 1990 and experiencing gradual growth to 3.8 million in 2000. The country is expected to see its population increase modestly to 4.3 million in 2020 and further to 4.7 million by 2050. Conversely, the United States exhibited substantial population growth, beginning at 249.9 million in 1990. This figure ascended to 320.6 million in 2020, with projections indicating a significant rise to 349.0 million by 2050, demonstrating the most pronounced growth rate of all four countries.
