The line chart illustrates the number of residents (in millions) from different regions, namely Australia, Asia, and other areas, along with the total number of residents over the period from 2015 to 2020.
Overall, the total number of residents showed a steady upward trend throughout the surveyed period. While the number of residents from Asia increased significantly, the figure for Australia saw a slight decrease, and the number from other regions fluctuated.
Delving into the details, the total population rose sharply from approximately 33 million in 2015 to over 50 million by 2020. Most notably, the number of residents from Asia experienced a substantial increase, starting at 10 million in 2015 and rising continuously to overtake the ‘Other’ category, reaching nearly 30 million by the end of the period.
In contrast, the number of residents from ‘Other’ regions was initially the largest group (excluding the total) with 20 million in 2015. It peaked in 2016 at around 25 million before gradually decreasing back to 20 million in 2020. Meanwhile, the population from Australia was the lowest, starting at approximately 3 million, rising slightly in 2016, and then gradually declining to under 5 million by 2020.
