IELTS Pie Chart Vocabulary


  • “per cent/percent”: Used after a number to indicate a portion out of a hundred, e.g., “Around seventy per cent of the population of Singapore is Chinese ancestry.”
  • “percentage”: Used without a number to refer to a part of something, e.g., “A significant percentage of Canada’s electricity is generated by hydroelectric power.”
  • “proportion”: Indicates a part of a whole, often used to express significance, e.g., “A larger proportion of the national budget is spent on education than on anything else.”
  • “portion”: Suggests a part of something, often used in a domestic context, e.g., “The family spends a significant portion of their income on housing.”
  • “share”: Refers to the part belonging to a party or group, e.g., “Two or three companies control a large share of the technology market.”
  • “segment”: Often used to describe a part of a market or demographic, e.g., “Only a small segment of the population uses this service.”
  • “fraction”: Indicates a small or minute part of something, e.g., “Only a tiny fraction of the total number of applications to this university are accepted.”

Fractions: When discussing pie charts, fractions can also be used to describe proportions:

  • “three quarters” can be expressed as 75 per cent, three out of four.
  • “a half” equates to 50 per cent, one out of two.
  • “a third” corresponds to one third or one out of three.
  • “a quarter” is 25 per cent, one out of four.
  • “a tenth” translates to 10 per cent, one out of ten.

These terms can be modified with qualifiers like “about,” “around,” “approximately,” or “just over” to convey estimates rather than exact figures.

Other useful expressions:

  • “account for”: To constitute or represent a part, as in “Rice accounts for about a third of their diet.”
  • “make up”: To compose or form, e.g., “Poisonous snakes make up only about ten per cent of all snake species.”
  • “represent”: To stand for or symbolize, e.g., “Accidents that occur while texting represent about a quarter of the total number of car accidents.”
  • “constitute”: To be part of a whole, as in “Rental properties constitute about a third of the company’s assets.”

Numbers and Amounts

When describing quantities or proportions, you can use various terms to accurately reflect the size of the group or segment being discussed. Here are some examples:


“a small minority” refers to a group that is smaller than the majority, but still significant enough to be mentioned.

“a large majority” indicates a group that constitutes most of the population or category in question.

“a significant portion” is used to describe a part of a group or category that is too notable to ignore due to its size or impact.

“a tiny fraction” is a term used for a very small part of a group or category, often insignificant in size but still relevant to the context.
