Pie Chart Overview
What Pie Charts Usually Show
Pie charts show how a whole is divided into different parts.
They may show proportions of: household spending, energy sources, population groups, reasons for travel, market share, types of waste, student nationalities, employment sectors, university expenses, etc.
Your job is to describe the main proportions and comparisons, not every slice one by one.
Two Main Types of Pie Charts
Single pie charts
These show the proportions of different categories at one point in time.
For single pie charts, focus on:
- the largest category
- the smallest category
- categories with similar shares
- categories that together make up a large proportion
- any category that clearly stands out
Useful language
- accounted for the largest share
- made up the smallest proportion
- represented nearly half of the total
- comprised around one quarter
- was slightly higher than
- was almost twice as large as
Multiple pie charts
These compare proportions across different years, groups, places, or categories.
For multiple pie charts, focus on:
- which categories increased
- which categories decreased
- which categories stayed similar
- which category was largest in each chart
- which category changed the most
- whether the overall distribution became more balanced or less balanced
Useful language
- the share of X increased
- the proportion of Y declined
- X became the largest category
- Y remained the smallest segment
- X overtook Y
- the distribution became more evenly spread

Pie Chart Reminders
1. Spend only 20 minutes
Spend only 20 minutes on Task 1 — Task 1 is worth half of the Task 2 score.
2. Do not describe every slice one by one
Group the data logically instead of listing each category mechanically.
3. Focus on proportions and ranking
Look for the largest share, smallest share, similar shares, and major differences.
4. Use percentage language accurately
Pie charts often show percentages, so use phrases like accounted for, made up, represented, and comprised.
5. Compare categories clearly
Do not just state numbers. Explain how one category compares with another.
6. Be careful with "percentage" vs "percentage point"
A rise from 20% to 30% is an increase of 10 percentage points, not 10 percent.
7. Do not explain causes
Unless the chart directly provides reasons, do not guess why one category is larger or smaller.
