The pie charts give information about the total expenditures of a UK school in the years 1981, 1991, and 2001.
It is clear that the largest proportion of spending was on teachers’ salaries in the three years, while the school spent the lowest money on insurance.
According to the diagrams, we can see that in 1981, 40% of school spending was on teacher’s salaries. This figure rose to 50% in 1991, while then decreased to 45% ten years later. On the contrary, the lowest part of expenditure, insurance, made up 2% of the total expenses in 1981, which is 1% lower than the proportion in 1991, and 6% lower than the proportion in 2001.
On the other hand, the school spent 28% of the money on other workers’ salaries, which was cut down in the period of 20 years, with 22% in 1991 and 15% in 2001. In addition, about 15% of expenses were on resources in 1981, compared with 20% in 1991 and 9% in 2001. The percentage of furniture and equipment was similar to resources in 1981, but it suddenly fell to 5% in 1991, then it increased to 23% in 2001, becoming the second compound of the annual spending.
