Task 1 · Dynamic Multiple-Line Graph
You should spend about 20 minutes on this task. Write at least 150 words.
The line graph below shows the past and projected population figures (in millions) for three major Australian cities from 1990 to 2040.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Part 1 · Band 9 Sample Answer
The line graph compares changes in the populations of Sydney, Melbourne and Brisbane between 1990 and 2020, together with projections for the following two decades. Figures are given in millions.
Overall, all three cities grew throughout the historical period and are expected to continue doing so. Sydney was the most populous city at every recorded point and is forecast to remain narrowly ahead in 2030. However, Melbourne grows more rapidly and is projected to take first place by 2040, while Brisbane remains considerably smaller despite substantial expansion.
In 1990, Sydney had approximately 3.5 million residents, compared with 2.8 million in Melbourne and 1.2 million in Brisbane. Sydney’s population then rose steadily to 3.9 million in 2000 and 4.3 million in 2010. Over the same years, Melbourne increased to 3.2 million and then 3.8 million, reducing its deficit behind Sydney from 700,000 to about 500,000. Brisbane experienced a gradual rise to roughly 1.5 million in 2000 and just under 1.9 million a decade later. By 2020, the three totals had reached around 4.7 million, 4.5 million and 2.35 million respectively.
The gap between the two largest cities is predicted to narrow further by 2030, when Sydney is expected to contain 5.1 million people and Melbourne 5 million. Thereafter, Melbourne should overtake Sydney and climb to 5.9 million in 2040, half a million above Sydney’s projected 5.4 million. Brisbane, meanwhile, is forecast to rise consistently to about 2.85 million in 2030 and 3.4 million at the end of the period.
Part 1 · Band 8 Sample Answer
The graph presents the populations of three large Australian cities from 1990 to 2040, measured in millions. The figures up to 2020 show past changes, while those for 2030 and 2040 are projections.
Overall, the population of every city rises across the period. Sydney is the largest city from 1990 until at least 2030, but Melbourne is expected to grow faster and become the most populous by 2040. Brisbane has the lowest figures throughout, although its population also increases considerably.
Sydney begins with 3.5 million inhabitants in 1990 and grows steadily to 3.9 million in 2000 and 4.3 million in 2010. Its population reaches approximately 4.7 million by 2020. Melbourne follows a similar upward pattern, rising from 2.8 million to 3.2 million and then 3.8 million over the first three dates. By 2020, it stands at 4.5 million, leaving a difference of only around 200,000 between the two cities. Brisbane starts much lower, at 1.2 million, before increasing to about 1.5 million in 2000, 1.85 million in 2010 and 2.35 million in 2020.
Looking ahead, Sydney and Melbourne are predicted to reach 5.1 million and 5 million respectively in 2030. Melbourne is then forecast to experience stronger growth, reaching 5.9 million in 2040 and moving ahead of Sydney, whose population is expected to be 5.4 million. Brisbane should continue its steady increase to roughly 2.85 million in 2030 and 3.4 million by 2040, remaining two million below Sydney at the end of the period.
Part 1 · Band 7 Sample Answer
The line graph shows the past and predicted populations of Sydney, Melbourne and Brisbane between 1990 and 2040. Population numbers are presented in millions, and the data after 2020 are forecasts.
Overall, all three cities show continuous population growth. Sydney has the highest population for most of the period, while Brisbane remains the smallest city. However, Melbourne is expected to pass Sydney before 2040 and finish with the largest population.
In 1990, about 3.5 million people lived in Sydney. This figure rose to 3.9 million in 2000 and 4.3 million in 2010 before reaching approximately 4.7 million in 2020. Melbourne also grew steadily, from 2.8 million in 1990 to 3.2 million in 2000. It then increased more quickly to 3.8 million in 2010 and 4.5 million by 2020. Therefore, the population gap between Sydney and Melbourne became much smaller.
Brisbane had a considerably lower starting point of 1.2 million. Its population increased to around 1.5 million in 2000 and just under 1.9 million in 2010. By 2020, it had reached roughly 2.35 million, which was still only about half the figure for Sydney.
In 2030, Sydney is forecast to have 5.1 million residents, slightly more than Melbourne at 5 million. By 2040, Melbourne is predicted to rise to 5.9 million and overtake Sydney, which should reach 5.4 million. Brisbane is also expected to continue growing, reaching about 2.85 million in 2030 and 3.4 million in 2040.
