The three pie charts illustrate the proportion of annual spending by a particular UK school, measured in percentages in the years 1981, 1991 and 2001.
Overall, the most noticeable feature is that the distribution of teachers’ salaries remained the largest contributor, whereas insurance accounted for the smallest percentage. In addition, other categories also experienced significant changes throughout the period.
In 1981, teachers’ salaries accounted for 40% of the total, followed by other workers’ salaries at 28%. While furniture and equipment and resources such as books were identical, both at 15%, insurance made up the smallest proportion which was 2%. Ten years later, teachers’ salaries increased gradually to 50%, becoming half of the total spending.
In contrast, furniture and equipment decreased from 15% to 5% between 1981 and 1991. Resources such as books rose steadily to 20% while the proportion of insurance remained low despite the increase from 2% to 3%. Other workers’ salaries showed a downward trend, declining from 28% to 22%, before dropping sharply to 15% in 2001. Teacher salaries decreased to 45% but remained dominant. Furniture and equipment climbed sharply to 23% while the proportion of other workers’ salaries declined to 15%. The percentage of insurance showed little change, reaching 8%. Resources declined from 20% to 9%, between 1991 and 2001.
