The line graph illustrates the population growth trends in three prominent Australian cities—Melbourne, Sydney, and Brisbane—from 1992 to 2016.
Overall, it is evident that the populations of all three cities experienced a significant increase initially; however, there were fluctuations throughout the observed period. While Sydney had the highest population at the outset, Melbourne eventually surpassed it by the end of the timeframe.
In 1992, the population of Melbourne was approximately 22,000. This number steadily escalated to reach 100,000 by 2009. Nonetheless, following this peak, the population witnessed a sharp decline before starting to increase again. Conversely, Sydney had an initial population of around 30,000, which exhibited fluctuations over the years, ultimately more than doubling by 2016.
Furthermore, Brisbane commenced with a population comparable to that of Sydney in 1992. Its population experienced a gradual rise until 2009, yet this was followed by a notable decline. By the end of the period in 2016, Brisbane’s population stabilized at approximately 45,000.
