The table illustrates the population figures and future predictions in various countries from 1990 to 2050. In general, the USA had the highest number of people, followed by Canada throughout the period. The lowest number of people was see in New Zealand while the figure for all countries is estimated to experience a growth.
A closer look at the table reveals that United States started at 249.9 million people before rising to 258.2 million by 1993. From that year onwards, it experienced an upward trend, reaching its peak of 320.4 million by 2020. However, by 2050 the USA will have 349.0 million people. Canada, on the other hand, had the second highest number of people, rising from 26.6 million in 1890 to 28.5 million in 1993. Despite this growth, it surged to 31.0 million in 2020 before peaking at 36.9 by 2050. Additionally, it is estimated that this figure will climb to 39.0 million in 2050.
In contrast, in 1990 17.1 million people were living in Australia although this number experienced a negligible increase, reporting 17.7 million in 1993. Specifically, while this country had 19.2 million people in 2020, this figure rose to 28.7 by 2050 which is estimated to reach 39.0 million by 2050.
Similarly, New Zealand also experienced a gradual rise across the years despite the small numbers. Between 1990 and 1993 it had 3.4 and 3.5 million people respectively, although it grew to 4.3 million by 2020. Notably, this population is predicted to experience a marginal growth, reaching 4.7 million people by 2050.
