What is a Line Graph in IELTS?

Each data point represents a specific value, and the lines help visualise the progression or fluctuations in the data over a specified period.

Use of Line Graph in IELTS Writing

Line bar graphs are a common type of visual data representation used in the IELTS Academic Writing Task 1.  Test-takers are presented with a line graph that depicts information related to a specific trend, such as changes in temperature, population growth, or economic data. Your task is to analyse the graph and write a descriptive report based on the provided information.

Structure of the IELTS Academic Writing Line graph

The structure of your IELTS Task 1 line graph typically consists of the following components -

Introduction - Provide a brief overview of the graph's subject, including the timeframe and data sources.

Overview - Summarise the main trends or patterns evident in the line bar graph. Mention the highest and lowest points, significant increases or decreases, and noteworthy observations.

Details and Comparisons - Present specific data points from the graph. Use data accurately to support your observations, and make comparisons where relevant.

Conclusion - Provide a concise summary of the key findings without introducing new information.

How to describe a Line graph in IELTS?

Describing a line graph effectively in IELTS involves the following steps -

Identify Trends - Start by identifying the major trends or changes in the graph. Look for upward or downward slopes, plateaus, spikes, or significant patterns.

Use Data Points - Refer to specific data points on the graph to support your description. Also, mention exact numbers, percentages, or values when applicable.

Vary Your Vocabulary - Utilise a rich and varied vocabulary to describe the data. In addition, use adjectives and adverbs to add nuance to your descriptions. For example, instead of saying "a significant increase," you can say "a substantial rise."

Provide Context - Offer contextual information that helps the reader understand the significance of the data. This could include reasons for the trends or comparisons with other data sets.

IELTS Line Graph Question

The graph below gives information from a 2008 report about the consumption of energy in the USA since 1980 with projections until 2030. Summarise the information by selecting and reporting the main features and make comparisons where relevant. Write at least 150 words.




IELTS Line Graph Response

The aforementioned line graphs showcase data extracted from a 2008 report detailing energy consumption trends in the USA from 1980, extending to projected figures up to 2030.

As an overview, it can be stated that there has been a consistent increase in the consumption of fossil fuels from the initiation of the period. Projections indicate a further dependence on these fuel sources. Conversely, cleaner energy sources have accounted for significantly less consumption, and forecasts anticipate a continuation of this pattern.

Within the realm of fossil fuels, including coal, natural gas, petrol, and oil, their energy consumption has shown consistent growth since 1980. Commencing at 35 quadrillion units in 1980, petrol and oil experienced fluctuations until 2000. Subsequently, they exhibited a stable and consistent increase, with a projected consumption surpassing 45 quadrillion units by 2030. Likewise, coal demonstrated a similar upward trend, with estimates indicating it will surpass 30 quadrillion units by 2030. Natural gas usage is expected to plateau at approximately 24 quadrillion units from 2020 onwards.

Conversely, at the onset of the period, cleaner energy sources began with consumption levels below 5 quadrillion units and showcased a decrease in their usage, except for nuclear power, which saw a slight uptick to 6 quadrillion units in 2005. Predictions anticipate a modest increase in the use of solar/wind energy. Moreover, hydropower is foreseen to sustain relatively constant consumption levels until 2030."
