IELTS Writing Task 1: Bar Charts
This task tests whether you can identify the most important comparisons and trends in a bar chart and describe them accurately, using varied language, without listing every single number.
What this question looks like
In Academic Task 1, a bar chart (or a mix including a bar chart) presents numerical data across categories, such as sales by country, energy use by sector, or survey results by age group, often across two or more years or groups. You must write a report of at least 150 words in about 20 minutes, summarising the main features and making relevant comparisons, without giving opinions. Bar charts may be single (one variable), grouped (clusters of bars per category) or stacked (segments within one bar), and this affects how you organise your comparisons.
Step-by-step approach
- 1Spend 2-3 minutes reading the chart before writing: identify what the bars measure, the units, the categories on the x-axis, and whether there is a time element or just a single snapshot.
- 2Find the overall pattern first: which category has the highest and lowest values, is there a clear order or grouping, and does data change over time or across groups. This becomes your overview paragraph, written in your own words with no exact figures.
- 3Group the bars logically for your body paragraphs rather than describing them left to right. Group by similarity (e.g. all categories that rose together), by theme (e.g. all transport-related bars vs all leisure-related bars), or by time period if the chart spans several years.
- 4Select only the data that supports the key comparisons: highest, lowest, biggest gap, biggest change, similar or identical values. Do not attempt to mention every single bar with its exact number.
- 5Use comparative and superlative language precisely: 'nearly double', 'roughly three times as many', 'the smallest proportion', 'a marginal difference of X percentage points'. This shows lexical range beyond simple 'more than/less than'.
- 6Check your numbers against the chart one final time. Wrong figures or reversed comparisons (saying A is higher than B when the chart shows the opposite) are Task Achievement errors that cap your score regardless of grammar quality.
Worked example
The bar chart below shows the percentage of households in four countries that owned a smartphone, a laptop and a games console in 2020. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The bar chart compares smartphone, laptop and games console ownership among households in four countries in 2020. Overall, smartphone ownership was consistently the highest of the three items across all countries, while games console ownership was the lowest everywhere except in Japan. There was also considerably more variation between countries in laptop and console ownership than in smartphone ownership. Smartphone ownership ranged narrowly from 88% in Brazil to 97% in South Korea, with the UK and Japan both close to 90%. This item showed the smallest gap between countries of any category on the chart. Laptop ownership varied more widely. South Korea and the UK led with around 82% and 78% of households respectively, whereas Brazil had a considerably lower figure of just 45%, less than half that of South Korea. Japan sat in the middle at approximately 65%. Games console ownership showed the most striking contrast. Japan stood out with 58% of households owning one, roughly double the proportion in the UK (29%) and almost three times that of Brazil (21%). South Korea recorded the lowest console ownership overall, at only 19%, despite having the highest smartphone and laptop figures. (198 words)
The overview identifies the two clearest overall patterns (smartphone always highest, console lowest almost everywhere) without listing numbers, satisfying the requirement for a data-free summary. Body paragraphs are grouped by item (smartphone, laptop, console) rather than by country, which keeps related figures together and allows direct comparison language ('roughly double', 'less than half', 'almost three times'). Only key figures are quoted, extremes and notable gaps, rather than every value, and the final paragraph highlights an interesting contrast (South Korea high on two items but lowest on the third) which shows analytical selection rather than mechanical listing.
Try it yourself
Write a full Task 1 report of at least 150 words. Spend about 20 minutes: 3 minutes planning, 15 writing, 2 checking your figures against the chart description.
The bar chart below shows the average number of hours per week that people in three age groups (18-30, 31-50, 51+) spent on four leisure activities (reading, watching TV, exercising, socialising in person) in a 2019 survey. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. (Imagine bars showing, per week: 18-30 group: reading 1.5hrs, TV 12hrs, exercise 3hrs, socialising 6hrs. 31-50 group: reading 2hrs, TV 10hrs, exercise 2hrs, socialising 4hrs. 51+ group: reading 5hrs, TV 15hrs, exercise 4hrs, socialising 3hrs.)
Common mistakes
- !Writing the overview last or omitting it entirely; without a clear overview paragraph identifying the main trend(s), the report cannot score above band 5 for Task Achievement no matter how detailed the body is.
- !Describing bars strictly left to right in the order they appear on the chart, which forces awkward repetition instead of grouping related data for stronger comparisons.
- !Listing every single figure from the chart, which wastes time and pushes the word count up without adding analytical value; examiners want selection and comparison, not a transcript of numbers.
- !Confusing the direction of a comparison (e.g. writing 'X was lower than Y' when the chart shows the opposite), a factual error that directly damages Task Achievement even if the sentence is grammatically perfect.
- !Using 'compared to' or vague words like 'a lot' repeatedly instead of precise comparative language such as 'nearly double', 'a marginal increase of 3 percentage points', or 'the second highest figure'.

Do I need to mention every bar in the chart?
No. Examiners want you to select and report the main features, not transcribe every value. Focus on extremes, clear trends, notable gaps and useful comparisons, and group less important data together briefly rather than listing each bar separately.
How many paragraphs should a bar chart report have?
Four is the standard structure: an introduction that paraphrases the question, an overview of the main trends, and two body paragraphs that group the data logically, for example by category, by time period, or by similarity of trend.
What if the bar chart has no time element, just one set of figures?
Then there are no trends to describe, only comparisons. Your overview should state the highest and lowest categories and any striking similarities or differences, and your body paragraphs should group categories by level (e.g. high, middle, low) rather than describing change over time.
