The three pie charts illustrate the amount of money spent in five different expense categories by a particular school in the UK in 1981, 1991 and 2001.
Looking at the charts, we see that Teachers’ salaries took up the major part of the spending over the twenty year period, and the biggest change was seen with expenditure on Furniture and equipment.
Specifically, Teachers’ salaries started out at 40% of the total expenses in 1981, reached a peak at 50% in 1991, and dropped back slightly to 45% a decade later. Following a similar pattern was Resources (such as books), which went from 15% to 20%, and then back to 9% over the period. Another large proportion of the budget was spent on Other workers’ salaries, but it declined steadily from 28% to 15% between 1981 and 2001.
The remaining two items saw the biggest relative changes from one year to the next. As mentioned earlier, Furniture and equipment was one of them. It plummeted from 15 to 5 percent, and then went back up to as high as 23%. Insurance, remained relatively unchanged over the first decade, but skyrocketed from 3% to 8% in the second half of the period.
