The essay below shows an example of a multiple pie chart essay question, where the categories are the same but each pie chart represents a different time period.

This is an example of a trend diagram. For most test-takers, diagrams where changes across time are shown are most easily described by focusing on the changes rather than the relative sizes of the categories.

However, you should always try to include a variety of sentence types and vary the way numbers are reported. The model essay below contains many examples for you to consider in your own writing.

Model essay

The pie charts illustrate the percentage of migrants employed in five economic sectors in Australia over a three year period from 2001 to 2003.

In general, the percentage of migrants working in healthcare and manufacturing decreased during the period, while figures for farming experienced a significant increase.

From 2001 to 2002, the percentage of migrants employed in healthcare fell marginally from around fifty-one percent to just under forty-eight. However, in the next year, numbers for healthcare experienced a dramatic fall by almost sixteen percentage points. During the same period, figures for manufacturing almost halved in the first year but then recovered significantly. However, despite this recovery, the proportion of migrants employed in this sector still decreased dramatically overall, from slightly more than eighteen percent to just over fourteen. 

In contrast, the percentages reported for farming, education and entertainment rose during the period, although only farming experienced a significant rise. In 2001, the number of Australian migrants working in farming was approximately twenty-one percent. In 2002 and 2003, this figure rose by more than ten percent, meaning that in 2003 the percentage of migrant workers employed in farming had more than doubled.
