The image displays three pie charts that illustrate annual school spending in the UK for three different years: 1981, 1991, and 2001. Overall, it is evident that the highest expenditure occurred in 1991 for teachers’ salaries, which accounted for 50% of the total spending, while the lowest expenditure was recorded on insurance in 1981 at just 2%.
Examining the details, in 1981, 15% of the total expenditure was allocated equally between resources, such as books, and furniture and equipment. Teachers’ salaries accounted for 40% of the total spending that year. In comparison, the amount spent on insurance was higher in 1981 (22%) than in 1991 (28%). In 1991, expenditures on resources like books made up 20%, while only 5% went toward furniture and equipment.
The third pie chart, which presents annual school spending for 2001, shows that the highest proportion of spending was again on teachers’ salaries at 45%, whereas the lowest was on insurance at 8%. There is only a slight difference in the spending proportions for other workers’ salaries and resources like books, which comprised 15% and 9% respectively, while 23% was allocated to furniture and equipment.
