What Are Unusual Trends in IELTS Writing Task 1?

Unusual trends are patterns in data that don’t follow the expected or linear progressions. These may include:

• Sudden spikes or drops

• Reversals or U-turns

• Irregular fluctuations

• Periods of no change followed by rapid shifts

• Anomalies that differ from the overall trend

Recognizing and describing these effectively shows examiners that you understand the data and can express complex ideas using appropriate vocabulary.

Step-by-Step Guide to Describing Unusual Trends

1. Understand the Overall Trend First

Before jumping into anomalies, summarize the general pattern in the introduction. This sets the context for describing exceptions.

Example:

Overall, the graph shows a consistent increase in smartphone usage between 2010 and 2020, with a notable dip in 2015.

2. Identify and Isolate Unusual Features

Look for data points that deviate from the general flow. Circle or underline:

• Sharp peaks or troughs

• Sudden halts or surges

• Outliers in comparison to other data

Example:

While most age groups experienced a steady rise in internet usage, the 60+ demographic dropped sharply in 2012 before rebounding in 2014.

3. Use Precise Vocabulary

When describing unusual patterns, go beyond basic terms like “increase” or “decrease.” Try:

• Surge, plummet, collapse, skyrocket

• Abruptly, unexpectedly, irregularly

• Deviate, fluctuate, reverse, remain static

Example:

Sales of tablets plummeted dramatically from 60,000 units in June to just 25,000 in July, marking a sharp deviation from the upward trend.

4. Quantify When Possible

Always include figures or percentages to support your analysis. This adds credibility and clarity.

Example:

The percentage of part-time workers jumped by 20% between March and April, in contrast to the previous month’s decline.

5. Make Comparisons Thoughtfully

Comparing normal versus unusual trends strengthens your task response.

Example:

Unlike the gradual increase in car sales from 2010 to 2014, the year 2015 saw a sudden 30% drop, possibly due to regulatory changes.

6. Use Linking Words and Phrases

Maintain cohesion by connecting ideas with:

• However, in contrast, while, despite this, although, whereas, unlike

Example:

Although most regions reported steady growth, sales in the southern district remained flat, defying the overall trend.

Sample Description with Unusual Trend

Task Prompt:
The line graph shows the number of tourists visiting three different countries from 2000 to 2020.

Sample Response:
Between 2000 and 2010, all three countries experienced a moderate rise in tourist arrivals. However, Country B saw an unprecedented surge in 2011, climbing from 2 million to 6 million visitors in a single year. This spike was followed by a sharp decline in 2012, falling back to 3 million. In contrast, Country C’s figures fluctuated irregularly, lacking a clear upward or downward trajectory. Meanwhile, Country A demonstrated a consistent growth trend throughout the entire period.

This example shows a range of vocabulary, clear comparisons, and thoughtful treatment of irregular data.
