The pie charts compare the differences in yearly spending, including insurance, teachers’
salaries, furniture and equipment, resources, and other workers’ salaries, between 20 consecutive years at a specific school in the UK, recorded from 1981 to 2001.
Overall, teachers’ salaries always accounted for the highest funding throughout the periods, while insurance remained the smallest category, even though its proportion increased year by year.
In 1981, salaries paid to the teaching staff made up 40% of the total spending, which then increased to half of the total school spending ten years later, before dropping slightly to 45% in 2001. In contrast, the spending on salaries for non-teaching staff went down steadily over the 20 years. It started at 28% in 1981, decreased to 22% in 1991, and reached the lowest level at 15% in 2001.
Regarding the other three categories, spending on resources like books showed a dynamic trend. It increased from 15% to 20% in 1991, but then dropped to 9% in 2001. On the contrary, spending on furniture and equipment fell from 15% in 1981 to 5% in 1991, but it increased significantly to 23% in the span of ten years. Finally, insurance was the only that showed an increasing trend, standing at only 2% in 1981. It went up to 3% in 1991 and then rose to 8% at the end of the period.
