The three pie charts below show the changes in annual spending by a particular UK school in 1981, 1991 and 2001.
The pie charts display yearly expenditure by a certain school in the UK in 1981, 1991 and 2001.
Overall, while teachers’ salaries remained the school’s greatest cost, furniture and equipment overtook other workers’ salaries as the second-largest expenditure by 2001.
Teachers’ salaries were what cost the school the most in all three years, accounting for 40%, 50%, and 45% of total spending respectively. The school spent the second largest proportion of its expenditure on other workers’ salaries in both 1981 and 1991, at 28% and 22% respectively. However, this proportion decreased to only 15% in 2001. Although spending on furniture and equipment dropped from 15% to 5% between 1981 and 1991, it went up sharply in 2001 and replaced other workers’ salaries as the second greatest expenditure that year, at 23%.
15% of the school’s expenditure was on resources in 1981. After a small growth in 1991, the figure decreased to only 9% in 2001. Despite increases, insurance received the smallest share of expenditure in all three years, at 2%, 3%, and 8% respectively. (174 Words)
How to Write the Overview
I think when it comes to pie charts, bigger slices are always more noticeable than upward and downward trends. That’s why I picked the two biggest categories in each of the three years as the main features of the charts.
How to Paraphrase the Chart Description
The Original: The three pie charts below show the changes in annual spending by a particular UK school in 1981, 1991 and 2001.
“Changes in” is wrong. The charts, when read together, show changes, but the changes shown are between 1981 and 1991, between 1991 and 2001, and between 1981 and 2001. There is no change in 1981. It would be far better to remove the word “changes” and just say that the charts show yearly expenditure in these three years.
