Now let’s look at another scenario where you are given two pie charts.
This type is actually much more common and more difficult to analyze. Let’s look at an example.
The charts below provide information on popular modes of transport in the city of Cambridge for the years 2008 and 2018. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Step 1: Analyze the charts and plan how to group the information
Here is a top tip for you. One of the most common mistakes that people make when they write about two pie charts is that they don’t compare and contrast them.
They describe each pie chart in a separate paragraph, which can cause them to lose marks.
The examiner gives you two pie charts on purpose—to test your ability to analyze how they relate to each other.
Therefore, you must compare and contrast the two charts in your report.
Here’s one way to group and compare the information effectively:
The first grouping:
Choose 2–3 segments that account for higher percentages in the first pie chart, and then describe how these segments change from the first to the second chart.
The second grouping:
Choose 2–3 segments that account for lower percentages in the first pie chart, and then describe how these segments change between the two charts.
Note: In nearly all charts or graphs in Task 1, there are three main trends — upward, downward, and stable.
It’s quite straightforward and doesn’t need to be complicated, as shown in the analysis table below.
| The first grouping |
Cars → decreased from 42% to 20% Buses → decreased from 30% to 25% |
| The second grouping |
Bicycles → increased from 17% to 30% Walking → increased from 11% to 25% |
Next, figure out if there are any general trends when comparing the two pie charts.
You can see that walking and cycling became more popular while cars and buses became less popular between 2008 and 2018.
Some students might add the following in their essay:
This trend can be explained by the increased focus on the environment in cities. People no longer want to use transport that causes pollution, so instead they choose to walk or cycle.
DO NOT DO THIS!
You don’t need to give reasons for the trend. You just need to correctly describe the trend based on the chart information.
Step 2: Write an essay using the recommended structure
Now that you’ve analyzed the task and grouped the data, it’s time to write your essay.
We recommend that you pause here and try writing your own essay using the language and structure covered in previous lessons.
Then, return to this lesson to review the model essay and analysis below.

Introduction
The pie charts compare the popularity of various modes of transportation used in Cambridge in 2008 and 2018.
Overview
Overall, after a decade, the general trend was that Cambridge’s population had moved away from using motorised vehicles in favor of human-powered transport by 2018.
The second paragraph describes the overall trend.
The past perfect tense is used to show how things had changed:
Structure: subject + had + past participle + by + year
Example: Cambridge’s population had moved away from using motorised vehicles, preferred by the majority in 2008, in favor of human propulsion by 2018.
Body Paragraph 1
In terms of vehicle transport, in 2008, cars were the most popular choice, preferred by 42% of people. This was followed by bus usage at 30%. Moreover, 72% of people used either of these forms of transportation. In contrast, over the next decade personal motor vehicle use declined significantly, and by 2018, it was the least popular transport form. On the other hand, bus usage dropped slightly by 5%.
This paragraph compares the popularity of car and bus travel in 2008 and 2018.
“In contrast” is used to highlight the difference between the two years.
Body Paragraph 2
However, human propulsion, represented by cycling and walking, was unpopular in 2008. Bicycles were chosen by only 17% of people, and walking was the least popular choice at 11%. Nevertheless, by 2018, cycling and walking combined experienced a 27% increase in popularity — their use nearly doubled.
This paragraph compares the popularity of cycling and walking between 2008 and 2018.
“Nevertheless” is used to contrast what happened in the two years.
