The pie charts provide an overview of the annual spending by a specific UK school in the years 1981, 1991, and 2001.
In 1981, the school allocated the highest portion of its budget, 40%, to teachers’ salaries. Other workers’ salaries constituted 28% of the spending, while resources such as books and furniture/equipment each accounted for 15%. Insurance made up the smallest expenditure at 2%.
By 1991, the spending pattern had shifted. Teachers’ salaries increased to 50%, making it the largest expenditure. The proportion allocated to other workers’ salaries decreased to 22%, while spending on resources (books, etc.) remained stable at 15%. There was a notable reduction in the budget for furniture and equipment, dropping to 5%. Insurance spending rose slightly to 3%.
In 2001, the distribution of the budget changed significantly. Teachers’ salaries, although still the largest category, decreased slightly to 45%. Other workers’ salaries continued to decline, reaching 15%. The expenditure on resources stayed constant at 15%, while spending on furniture and equipment saw a significant increase to 23%. Insurance costs also rose considerably, accounting for 8% of the total budget.
In summary, teachers’ salaries consistently represented the largest share of the school’s budget over the 20-year period, despite some fluctuations. Notable trends include a substantial increase in spending on furniture and equipment by 2001 and a gradual decline in the allocation for other workers’ salaries.
