The table depicts and predicts, in millions of people, the population of four nations from 1990 to 2050.
Overall, there is an increase in the number of residents in each country, and the US showed the most substantial rise out of the four. Additionally, New Zealand remains the least populated nation over the period.
Regarding the United States, the figure started at 249.9 million in 1990, which far exceeded others. Thereafter, it rose steadily over the course of ten years, followed by a subsequent soar of over 45 million to 320.6 in 2020, before ending the period at nearly 350 million people in 2050.
As for Australia, about 17 million people were living in this nation at the beginning. Subsequently, the number increased at a gradual rate, reaching 19.2 in 2000, and is anticipated to peak at precisely 26 fifty years later. Canada experiences a similar change, albeit to a greater extent, beginning at 26.6 million, over one-tenth of the US’s population in the same year. The number continues to grow to 28.5, 36.9, and 39 in 1993, 2020, and 2050, respectively.
Finally, in New Zealand, there were only 3.4 million people residing here in 1990, and then it witnessed a moderate growth over time to reach 4.3 in 2020, before a projection of 4.7 million in 2050.
