IELTS Task 1: Bar charts
A bar chart compares quantities across categories. The whole decision is how to group the bars, because the grouping becomes the two body paragraphs and a report that walks through every bar in order reads as a list.
Group before you write
- Highest against lowest — the clearest grouping when values are spread.
- By category — where the bars fall into natural families.
- Over time — where the horizontal axis is years, which makes it a trend chart in bar form.
Decide the grouping in the first two minutes and the report has a shape. The overview then almost writes itself: it is the statement of why that grouping is the right one.
Comparison language
| Relationship | Language |
|---|---|
| Much bigger | far higher than, more than double, three times as many as |
| Slightly bigger | marginally higher than, slightly above |
| About equal | roughly the same as, comparable to, on a par with |
| Extremes | the highest figure, the lowest of any category, second only to |
Use a mixture of fractions, multiples and percentages rather than repeating one form. Accuracy matters more than variety, though: a wrong multiple is a Task Achievement error, not a vocabulary one.

Then it is behaving like a line graph. Describe trends over time and compare the categories within them.
