The given pie charts compare the expenditure of a school in the UK for five different purposes over a 20-year period.
It is clear that the largest percentage of the school’s spending belonged to teachers' salaries, the opposite was true for insurance in all three years (1981, 1991, and 2001).
In 1981, the proportion for teachers’ salaries accounted for 40%, while that of resources, furniture and equipment both reached 15%. After that, a half of the school's budget went on teachers’ salaries before falling again by 5% in 2001. On the other hand, after 20 years, school tended to invest more in facilities, at nearly a quarter. But in contrast, the percentage of spending on resources just increased by 5 percent before witnessing a significant decrease to 9 percent in 2001.
During the same period, the proportion for other workers’ salaries and insurance observed a completely different trend. From 1981 to 2001, expenditure on insurance stood at only 2% of the total and then rose each 10-year period till it reached 8 percent. By contrast, this figure for other workers’ salaries occupied 28% in 1981, then fell by 6 percent after 10 years and finally dropped to 15% in 2001.
