The pie charts provide information about the percentage of school expenditure in England in the periods 1981, 1991, and 2001. Overall, it can be seen that the general trend for total school output was an increase, except for the salaries of other workers and literature throughout the time scale.
Focusing on the teacher salary, spending in this category was higher than others; this stood at 40, then upward to 50 percent during the first 10-year period, and had slightly gone downward again to 45 percent in 2001. Meanwhile, there was a growth in expenses for furniture and equipment after experiencing a dramatic fell; this started at 15 and then became 5 percent in the first decade but went up again to 23 percent over the two decades. Next, in the insurance, the number of costs gradually rose over the given period, beginning at 2 in the initial year and reaching 3, then becoming 8 percent in the last year.
Moving to other staff salaries, the payment in these kinds of categories went down steadily over the 20 years, from 28 to 22, then touching 15 percent. Furthermore, the proportion of cost for resources such as books had declined from 15 to 20 percent and dropped rapidly to 9 percent.
