Vocabulary for Describing Trends

One of the most common question types in IELTS Writing Task 1 involves describing line graphs and bar charts, which show changes over time. Here are some useful words and phrases:
 

Increasing Trends:

• Rise (e.g., The sales figures rose significantly.)

• Increase (e.g., The population increased steadily.)

• Go up (e.g., The number of tourists went up sharply.)

• Climb (e.g., The percentage of users climbed gradually.)

• Surge (e.g., The demand for electric cars surged in recent years.)
   

Decreasing Trends:

• Decline (e.g., The unemployment rate declined slightly.)

• Drop (e.g., The percentage of smokers dropped sharply.)

• Fall (e.g., The cost of living fell marginally.)

• Decrease (e.g., The production of coal decreased gradually.)

• Plummet (e.g., The price of crude oil plummeted last year.)
   

Stable and Fluctuating Trends:

• Remain steady (e.g., The birth rate remained steady for a decade.)

• Stabilize (e.g., The market prices stabilized after the recession.)

• Fluctuate (e.g., The sales figures fluctuated throughout the year.)

• Level off (e.g., The inflation rate leveled off after the economic recovery.)
   

Vocabulary for Making Comparisons

When describing bar charts, tables, and pie charts, candidates need to compare different data points effectively. The following phrases help express comparisons:

• More than / Less than (e.g., The literacy rate in Country A is higher than in Country B.)

• The highest / The lowest (e.g., The USA had the highest GDP growth in 2022.)

• Compared to / In comparison with (e.g., Compared to last year, the crime rate has decreased.)

• Significantly higher / Slightly lower (e.g., The revenue was significantly higher in 2021.)

• Twice as much / Three times more than (e.g., The company produced twice as many units as before.)
   

Vocabulary for Describing Processes and Maps

When explaining a process diagram or map description, it’s essential to use clear sequencing words and passive structures.
 

Sequence Words:

• First / Initially (e.g., Initially, the raw materials are collected.)

• Then / Next (e.g., Next, the liquid is heated at high temperatures.)

• After that / Following this (e.g., After that, the mixture is cooled.)

• Finally / At the end (e.g., Finally, the packaged goods are distributed.)
   

Passive Voice for Process Descriptions:

• Is heated / Is filtered (e.g., The water is filtered before being bottled.)

• Is transported / Is collected (e.g., The waste materials are collected for recycling.)

• Is produced / Is manufactured (e.g., The final product is manufactured in factories.)
