Understanding how to effectively compare data is an essential skill for the IELTS Writing Task 1, especially when presented with graphical representations such as bar charts, line graphs, or tables. Today, we will explore the topic “Comparing Levels of Obesity in Different Countries (2000-2023),” a common theme within the IELTS exam. This lesson will guide you through a detailed analysis, a sample writing task, and tips for effectively approaching such tasks.
Analyzing the Essay Topic
Firstly, let’s take a look at the proposed topic: “Comparing Levels of Obesity in Different Countries (2000-2023)”. In the IELTS Writing Task 1, you often encounter questions that ask you to compare statistical data over different years or among different groups. When comparing levels of obesity in different countries from 2000 to 2023, you need to pay attention to multiple aspects like trends, differences, and significant changes.
Sample Prompts
-
The bar chart below shows the levels of obesity among adults in four different countries (USA, UK, Germany, and Japan) in the years 2000, 2010, and 2023. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
-
The line graph depicts the percentage of obese individuals across five different countries (USA, Canada, Australia, Germany, and Japan) from 2000 to 2023. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
-
The table below provides data on the obesity rates in ten different countries for the years 2000, 2010, and 2023. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
For today’s example, let’s proceed with the second prompt.
Sample Dataset and Chart
For this exercise, I’ll create a hypothetical line graph showing the obesity rates in five countries: USA, Canada, Australia, Germany, and Japan, from 2000 to 2023.
Sample Line Graph:
| Year | USA | Canada | Australia | Germany | Japan |
|---|---|---|---|---|---|
| 2000 | 30% | 25% | 28% | 20% | 10% |
| 2005 | 32% | 27% | 29% | 21% | 12% |
| 2010 | 34% | 28% | 30% | 22% | 14% |
| 2015 | 35% | 29% | 31% | 23% | 16% |
| 2020 | 36% | 30% | 32% | 25% | 18% |
| 2023 | 37% | 32% | 33% | 27% | 20% |
Task Analysis
The task asks you to summarize the information by highlighting key features and comparing relevant data. Pay attention to the following aspects:
-
Overall Trends:
- Identify whether the obesity rates increased or decreased over the given period.
- Note which country had the highest and lowest obesity rates throughout the period.
-
Rate of Change:
- Determine which country experienced the most significant increase or decrease.
- Compare the changes between the mid-periods (2005, 2010, 2015) and mention any drastic changes.
-
Important Intervals:
- Pinpoint specific years where notable changes occurred.
- Compare rates between countries during milestone years (2000, 2010, 2023).
Sample Writing Task
Now, let’s create a model answer using the provided data.
Model Answer:
The line graph illustrates the percentages of obesity among adults in five countries – USA, Canada, Australia, Germany, and Japan – from 2000 to 2023.
Overall, obesity rates showed an upward trend in all the listed countries during the given period. The USA consistently had the highest obesity rates, while Japan maintained the lowest rates throughout the years.
In 2000, the USA started with a 30% obesity rate, followed by Australia at 28%, Canada at 25%, Germany at 20%, and Japan lagging far behind at 10%. By 2005, obesity rates increased slightly across all countries. In the USA, the prevalence increased to 32%, and similarly, Canada saw a rise to 27%. Australia, Germany, and Japan followed similar trends with percentages rising to 29%, 21%, and 12% respectively.
From 2010 onwards, the obesity rates not only continued to rise but accelerated in some countries. The USA saw its rate increase to 34%, whereas Canada’s rate rose to 28%. Australia and Germany exhibited gradual yet steady increases, reaching 30% and 22% respectively. Notably, Japan’s rate climbed to 14%, which was still significantly lower compared to other countries.
Throughout the subsequent years, the upward trend persisted. In 2015, the USA’s obesity rate surged to 35%, maintaining the lead. By 2023, the USA and Canada reached their peak obesity rates of 37% and 32% respectively. Australia also reached 33%, while Germany exhibited a notable rise to 27%. Japan, although it continued to have the lowest obesity rates, showed a significant increase from 10% to 20% over the entire period.
In conclusion, despite the upward trajectory in all countries, the rates of increase and the final obesity percentages varied significantly. The USA emerged with the highest obesity rates, whereas Japan, despite its gradual increase, remained the lowest.

Key Considerations When Writing
Grammar and Vocabulary Tips
Complex Sentences: Use a mix of simple, compound, and complex sentences to enhance readability and create a well-structured piece.
Example: “By 2005, obesity rates had increased slightly across all countries, with the USA’s prevalence rising to 32% and Canada’s to 27%.”
Comparative and Superlative Forms:
- Comparative: “Canada’s obesity rate was higher than that of Japan.”
- Superlative: “The USA had the highest rate of obesity throughout the period.”
Cohesive Devices: Use linking words to ensure smooth transitions.
Examples: however, whereas, throughout, meanwhile.
