Band 8+: the table below gives information about past and projected population figures in various countries for different years. summarise the information by selecting and reporting the main features and make comparisons where relevant.

The table presents population figures (in millions) for four countries—Australia, Canada, New Zealand, and the United States—across the years 1990, 1993, 2000, 2020, and projected data for 2050.

In 1990, the United States had the highest population at 249.9 million, followed by Canada at 26.6 million, Australia at 17.1 million, and New Zealand with the smallest population at 3.4 million. Over the years, populations in all countries steadily increased. By 2020, the U.S. grew to 320.6 million, and it is projected to reach 349 million by 2050. Similarly, Canada’s population increased to 36.9 million in 2020, with a projection of 39 million in 2050. Australia’s population rose from 17.1 million in 1990 to 22.7 million in 2020 and is expected to reach 26 million by 2050. New Zealand experienced more modest growth, with 4.3 million in 2020 and an expected 4.7 million by 2050.

The U.S. remains the most populous throughout the years, while New Zealand consistently has the smallest population. The overall trend for all four countries is positive population growth.
