The pie charts illustrate the yearly expenditure of a school in the United Kingdom across three different years: 1981, 1991, and 2001. Overall, it is evident that teachers’ salaries accounted for the largest proportion of spending throughout the period, while insurance represented the smallest share.
Teachers’ salaries showed a fluctuating trend, standing at 40% in 1981, rising to 50% in 1991, and then slightly declining to 45% in 2001. In contrast, expenditure on other workers’ salaries, which was the second-largest component in 1981, consistently decreased over time, falling from 28% in 1981 to 22% in 1991 and further to 15% in 2001.
Insurance, although the smallest category, demonstrated steady growth, increasing from only 2% in 1981 to 3% in 1991, and then reaching 8% in 2001. Spending on resources such as books fluctuated, rising from 15% in 1981 to 20% in 1991 before falling back to 9% in 2001. Similarly, furniture and equipment also showed variation, starting at 15% in 1981, dropping to 5% in 1991, but then climbing significantly to 23% in 2001.
In summary, while teachers’ salaries consistently made up the largest portion of the budget, other workers’ salaries experienced a steady decline. Conversely, insurance and furniture expenditures rose considerably by the end of the period.
