What is a Pie Chart in IELTS Writing Task I?

A pie chart is a circular chart divided into sections to show percentages or proportions.

In IELTS Writing Task I, pie charts are used to:
 

• Compare data
• Show percentages
• Explain changes over time

Types of Pie Charts in IELTS

 

• Single Pie Chart: It is quite rare, but does come up at times. It is used to show information for one year or one situation.
• A Pair of Pie Charts: This is the most common variation of pie charts in IELTS. It usually compares data between two categories or time periods.
• Multiple Pie Charts: This is used to show comparisons between various years, places, or groups.

IELTS Pie Charts Structure

A strong structure is a basic requirement for a high score.
 

Introduction

Paraphrase the title of the question for a simple yet effective introduction.

Example:

The pie charts illustrate the percentage of public sector staff employed by age in the UK in 2015 and 2020.

For better band (if there are two pie charts):

The first pie chart illustrates the percentage of public sector staff employed by age in the UK in 2015, and the second chart compares the changes in figures five years later.

Note: Do not copy the question directly.

Overview

The overview is a summary of the main trends without providing specific details.

Include:
 

• Largest categories
• Smallest categories
• Major increases or decreases

Note: DO NOT include exact numbers here.

Example:

Overall, employment increased among people aged 21-30 and 41-50, while the other groups experienced a decline.
 

Body Paragraph 1

Make sure you include and describe:
 

• Major categories

Band 9 Sample Pie Chart Answer with Explanation

Question: The three pie charts below show the changes in annual spending by a particular UK School in 1981, 1991 and 2001.



Band 9 Sample answer:

The given pie charts illustrate how a UK-based school distributed its annual spending across five categories in 1981, 1991, and 2001.

Overall, teachers’ salaries accounted for the largest segment of spending in all the given years, while insurance remained the smallest expenditure category despite increasing gradually over a period of twenty years.

In 1981, 40% of the school budget was allocated to teachers’ salaries. This figure rose by ten percentage points after a decade before dropping to 45% in 2001. Meanwhile, the expenses on other workers’ salaries decreased from 28% in 1981 to 22% in 1991, and declined further by 7% at the end of the period.

The expenditure on furniture and equipment fluctuated over the given period, dropping from 15% to 5% in the first ten years, and then jumping significantly to nearly one-fourth (23%) of the total spending in 2001.

By contrast, spending on resources such as books demonstrated an opposite pattern, first rising from 15% to 20%, and then slipping to 9%. Insurance had the smallest figures in all the years, although it rose from 2% in 1981 to 8% in 2001.
 

Why This Sample Scores Band 9

 

• Clear Overview: Main trends are clearly reported, and are easy to understand.
• Strong Comparisons: The answer compares categories instead of making a list of data.
• Accurate Vocabulary: The sample uses a wide range of words like "segment," "category," "gradually," "decade," "significantly," "demonstrated," "pattern," and so on. 
• Good Grammar: Uses correct past tense throughout the answer.

 

Common Mistakes to Avoid in IELTS Pie Chart Writing

Missing the Overview: This is one of the biggest mistakes in IELTS Writing Task I.

Listing Numbers Only: Do not simply copy and report data - compare it.

Wrong Tense: Use:
 

• Past tense for past years
• Present tense for current data

Note: Avoid over-explaining small details. Focus instead on reporting the main trends and changes.

Expert Tips to Score Band 7+ in IELTS Pie Charts

 

• Write the Overview First: This helps to organize your ideas and separate information for proper paragraphing.
• Compare Data: The task asks you to ‘make comparisons where relevant’. Therefore, just describing and copying the percentages individually is not enough.
• Use Approximate Figures: You don’t always need exact figures. Try approximating with words like ‘around’, ‘about’, ‘nearly’, ‘just under’, ‘just above’ and so on.
• Keep it concise: The task also requires you to ‘summarize the information’. Hence, avoid unnecessary details, and focus on reporting the most important trends/features.

Note: My IELTS teaching experience suggests that students particularly need to practice using comparative language through regular IELTS practice tests to achieve a high band score in IELTS Writing Task I.
