The table illustrates the number of population in four different countries, over various years: 1990, 1993, 2000, 2020, and 2050 (projected).
Overall, the total number of population steadily increased throughout the period, with the USA contributing the largest amount, whereas New Zealand showed the least one. In addition, the US is expected to gain the most population at the end of the period.
In more detail, out of three nations, the US stood out with a remarkable difference in its number of people over the entire period. In 1990, the population in the US was nearly 250 million, and these figures then gradually rose over the following years. It reached just over 275 million in 2000, afterwards it climbed significantly to more than 320 million. At the end of the period, it is predicted to grow to 349 millions of people.
In contrast, Canada, Australia and especially New Zealand showed relatively lower, and had almost increasement over the years. At the beginning of the period, Canada had around 27 millions of people, while Australia and New Zealand had a lot less, with 17 million and 4 million, respectively. Following years, the population of Australia and Canada steadily continued to grow, with streaking 19 million and 23 million in 2000. New Zealand’s population, on the one hand, slowly increased to 3,8 million in the same year. In 2020, all three countries saw noticeable progress in their number of people, with the most increasing being nearly 6 millions in Canada. The amount of people in Canada will reach a solid 39 million, whereas the same figure in Australia is projected to gain 26 millions. New Zealand, on the other hand, will stay at the lowest, with 4.7 millions.
