How to describe a bar chart in one paragraph

A bar chart paragraph has one job: tell the reader what the chart shows, most important first, without adding anything the chart does not contain. It is the core skill of IELTS Academic Writing Task 1 and of every data summary at work, compressed into 90–140 words.

The task

The brief

A bar chart shows placement offers at one college for 2024: Computer Science 310 offers, Electronics 145, Mechanical 96, Civil 41, Biotechnology 22. Write ONE paragraph describing what the chart shows. Report the overall pattern first, then the notable figures. Do not speculate about causes.

Points to cover
  • State the overall pattern before any individual figure

  • Quote at least three figures accurately

  • Make an explicit comparison between branches

  • Avoid speculating about causes the chart does not show

Length

90–140 words


Suggested time

Level

Planning tip: Open with the trend, not with "The chart shows". Then two or three figures that carry the pattern. Never invent a reason the data does not contain.

What a strong answer does

  • The first sentence gives the overall pattern (which category dominates, how even or uneven the bars are) instead of announcing that a chart exists.

  • At least three figures are quoted exactly, with their units, and they are the figures that carry the pattern: the highest, the lowest, and a gap worth noticing.

  • There is an explicit comparison, such as ‘roughly double’, ‘less than a tenth of the leader’ or ‘together, the two smallest made up under a fifth of the total’.

  • Every comparison is calculated correctly. If you write ‘twice as many’, check that it is twice.

  • Nothing is guessed. The chart does not say why the bars differ, so neither does the paragraph.

  • The order is logical: overview, the leader, the middle as a group, the smallest, and perhaps one closing comparison.

How to structure it

  1. 1

    Overview sentence

    20–30 words

    The overall pattern in one sentence, with what the chart measures folded into it.

  2. 2

    The leading category

    20–30 words

    The highest figure, quoted exactly, compared with the next one down.

  3. 3

    The middle of the range

    20–30 words

    Group the middle categories together rather than giving each its own sentence.

  4. 4

    The smallest, and one closing comparison

    25–35 words

    The lowest figure, then one comparison that captures the spread: a ratio, or a share of the total.

Useful phrases

Frames, not finished sentences: put your own details where the [brackets] are, and use only the ones that fit what you are saying.

Giving the overview

  • [Measure] was heavily concentrated in [category].
  • The distribution was very uneven: [pattern].
  • Overall, [category] accounted for [share] of all [items].

Quoting figures

  • [Category] led with [number] [units].
  • [Category] came next with [number], less than half the leading figure.

Comparing

  • [A] recorded roughly twice the figure for [B].
  • Taken together, the two smallest [categories] reached only [number].
  • The gap between [A] and [B] was [number] [units].

Grouping the middle

  • [B] and [C] sat in the middle of the range, at [number] and [number] respectively.

Neutral reporting verbs

  • recorded · accounted for · made up · was followed by · trailed

Common mistakes, and how to fix them

Opening with ‘The given bar chart shows…’.

It restates the brief and spends your most important sentence on nothing. Examiners call it copying the rubric.

Fix: Open with the main pattern, and mention what the chart measures inside that sentence.

Listing every bar in order.

Five sentences of ‘X had this many, Y had that many’ is a table written as prose. The reader still has to find the pattern, which is your job.

Fix: Lead with the pattern, use the figures as evidence for it, and group similar categories.

Explaining causes.

A clause such as ‘because companies prefer this subject’ is not in the chart, and this brief forbids it.

Fix: Describe; do not explain. If you are about to write ‘because’, delete the clause.

Comparisons that do not add up.

Calling a figure ‘half’ or ‘a third’ of another when it is not is a factual error, and accuracy counts towards task response.

Fix: Do the arithmetic. ‘Less than half’ and ‘roughly a third’ are safe only when they are true.

Dropped or mixed past tenses: ‘Region C receive 58’, ‘it has 73 and had 19’.

The data covers a finished year, so the past simple is natural. Learners whose first language does not mark tense on the verb (Chinese, Vietnamese, Indonesian, Thai) often drop the ending.

Fix: Pick the past simple and keep it: ‘recorded’, ‘accounted for’, ‘was followed by’.

Figures without units, in informal verbs: ‘Region C got 73.’

Without a unit the number floats, and ‘got’ is too casual for a data description.

Fix: Write ‘Region C recorded 73 sales.’ Repeat the unit at least for the first and the largest figure.

Before you submit: a self-check

  • Does your first sentence give the overall pattern instead of restating the brief?

  • Have you quoted at least three figures exactly, with units?

  • Is there at least one explicit comparison, and is the arithmetic right?

  • Have you removed every ‘because’ and every guess about causes?

  • Is the tense consistent throughout?

  • Is it one paragraph of 90–140 words?

Questions people ask

How do you start describing a bar chart?

With the overall pattern: the category that dominates, or how even or uneven the bars are. Mention what the chart measures within that sentence. Avoid opening with ‘The bar chart shows…’, which only restates the task.


How many numbers should I include?

Enough to support the pattern, usually three to five: the highest, the lowest, and the figures that make your comparison. Quoting every number turns the paragraph back into a table.


Should I explain why the numbers are different?

Not in a data description. Unless the task asks for causes, describe only what the chart shows. Guessing at reasons is penalised in IELTS Academic Task 1 and is a common criticism of reports at work.


Is this the same as IELTS Academic Writing Task 1?

It practises the core skill. Task 1 asks for at least 150 words in about 20 minutes, usually with an overview and detail paragraphs; this task compresses that into a single paragraph, which is excellent training for writing a sharp overview.
