The three pie charts give information about the expenditure of a specific school in the UK over a 20-year timeframe (1981, 1991, and 2001).
Overall, the biggest proportion of expenditure was allocated for teachers’ wages, dominating throughout. Meanwhile, spending on insurance remained as the lowest-ranking sector.
In 1981, the majority of the school’s budget was spent on teachers’ salaries (40%), witnessing a slight increase of 10 percentage points the following decade. By 2001, the figure declined marginally to 45%. Moreover, spending at the UK school for workers’ salaries was the least, starting at 28% and declining markedly to 15% by the end of the period. The smallest change occurred in the percentage of insurance, beginning at a mere 2%, and increasing gradually by 6% over the decades.
Resources, furniture and, equipment displayed similar trajectories in 1981 (15% each). The figure for resources rose to 20% before dwindling to 9% in 2001. Expenditure on furniture and equipment exhibited a 10-percent decrease until 1991 and improved to almost a quarter in 2001.
