The three pie charts compare the distribution of a UK school’s annual spending across five categories—teachers’ salaries, other workers’ salaries, resources, furniture and equipment, and insurance—in the years 1981, 1991, and 2001.
In 1981, teachers’ salaries accounted for the largest portion at 40%, followed by other workers’ salaries at 28%. Spending on resources and furniture/equipment was equal, at 15% each, while insurance had a minimal share of 2%.
In 1991, the school increased its spending on teachers’ salaries to 50%. Resources also rose to 20%, but spending on other workers’ salaries decreased to 22%, and furniture/equipment dropped to just 5%. Insurance increased slightly to 3%.
By 2001, teachers’ salaries remained the largest expenditure at 45%, though spending on furniture and equipment rose sharply to 23%. Resources decreased to 9%, other workers’ salaries fell to 15%, and insurance grew to 8%.
In summary, teachers’ salaries consistently held the highest share, while spending on insurance increased gradually over the years.
