IELTS Academic Writing Task 1
Tables, Bar Charts, Line Graphs & Pie Charts: Band 8+ Outline
STEP 1: Analyse the Data First
Before writing, students should quickly identify:
Question
What to look for
What is being measured?
number, percentage, amount, proportion, expenditure, population, etc.
Is there a time period?
If yes → identify beginning and ending years
Are there major increases?
↑
Are there major decreases?
↓
Are there fluctuations?
↕
Are some figures stable?
→
Which are highest?
H
Which are lowest?
L
Are there obvious similarities?
≈
Are there major contrasts?
≠
Then decide:
TYPE A: Trend-based data
Use when the major story is changed over time.
Increase → Decrease → Fluctuation → Stability
PARAGRAPH 1: INTRODUCTION + OVERVIEW
Sentence 1 — Introduction
The given [line graph/bar chart/table/pie chart] illustrates/compares [topic] in/among [place/group] over the period from [year] to [year].
For a single-year chart:
The given [chart] illustrates/compares [topic] in/among [place/group] in [year].
Sentence 2: Overview
This is where students choose according to the data.
Overall, [X] experienced a significant increase, whereas [Y] showed a downward trend. Meanwhile, [Z] fluctuated throughout the period.
Or:
Overall, the figures for [X] and [Y] increased, while [Z] declined considerably. [A] remained relatively stable during the period.
⭐ Golden rule for the overview
Students should mention 2–3 major features, not every number.
PARAGRAPH 2 — MAIN BODY
1. Increases
It is evident that several categories experienced an increase during the given period. For instance, [X] rose from [figure] in [year] to [figure] in [year]. Furthermore, [Y] also increased considerably, reaching [figure] by the end of the period.
Useful language:
· rose
· increased
· grew
· climbed
· went up
· experienced an upward trend
· recorded a significant increase
2. Decreases
By contrast, [X] experienced a decline during the same period, falling from [figure] to [figure]. Similarly, [Y] decreased considerably over the period.
Useful language:
· fell
· declined
· decreased
· dropped
· went down
· experienced a downward trend
PARAGRAPH 3 — OTHER TRENDS
3. Fluctuations
In addition, some figures fluctuated throughout the period. [X], for example, rose initially before falling to [figure] and subsequently recovering to [figure].
Useful language:
· fluctuated
· varied
· rose and fell
· experienced fluctuations
· reached a peak of
· fell to a low of
4. Stability
Finally, [X] remained relatively stable throughout the period, showing little variation and staying at approximately [figure].
Useful language:
· remained stable
· remained unchanged
· showed little variation
· remained constant
· changed only marginally
TYPE B: Comparison-based data
Use when the major story is differences between categories.
High → Low → Similarities/Contrasts → Stability
This structure is particularly useful for single-year tables, pie charts and bar charts, although it can also work for some time-series data.
Sentence 1 — Introduction
The given [line graph/bar chart/table/pie chart] illustrates/compares [topic] in/among [place/group] over the period from [year] to [year].
For a single-year chart:
The given [chart] illustrates/compares [topic] in/among [place/group] in [year].
Sentence 2 — Overview
This is where students choose according to the data.
Overall, [X] recorded the highest figure, whereas [Y] had the lowest. In addition, [A] and [B] showed relatively similar figures.
Or:
Overall, [X] was by far the largest category, while [Y] accounted for the smallest proportion. The remaining categories showed comparatively moderate figures.
PARAGRAPH 2 — HIGH FIGURES
Several categories recorded relatively high figures. [X] had the highest value, at [figure], followed by [Y] at [figure]. Furthermore, [Z] also recorded a comparatively high figure of [figure].
Useful expressions
· recorded the highest figure
· had the largest proportion
· accounted for the greatest share
· was considerably higher than
· was followed by
· ranked second
PARAGRAPH 3: LOW FIGURES + OTHER COMPARISONS
Low figures
By contrast, [X] recorded the lowest figure, at [figure]. Similarly, [Y] also accounted for a relatively small proportion, at [figure].
Similarities
Meanwhile, [X] and [Y] recorded relatively similar figures, at [figure] and [figure], respectively.
Stability — when applicable
For a multi-year comparison:
As for [X], its figure remained relatively stable throughout the period, changing only slightly from [figure] to [figure].
🔑 MASTER STRUCTURE
Students should follow this simple decision tree:
ANALYSE THE DATA
│
┌────────────┴────────────┐
│ │
CHANGE OVER TIME MAINLY COMPARISON
│ │
TYPE A TYPE B
│ │
┌─────┼─────┐ ┌─────┼─────┐
│ │ │ │ │ │
↑ ↓ ↕/→ HIGH LOW SIMILAR
│ │ │ │ │ │
└─────┴─────┘ └─────┴─────┘
│ │
Paragraph 2: Paragraph 2:
↑ + ↓ HIGH
│ │
Paragraph 3: Paragraph 3:
↕ + → LOW + OTHER
⭐ Final Student-Friendly Formula
P1 — Introduction + Overview
WHAT + WHERE + WHEN → 2/3 BIGGEST FEATURES
P2 — Main Feature Group
Increase/High figures
P3 — Remaining Feature Group
Decrease/Low figures + Fluctuation/Stability/Similarity
