The diagrams depict data about alterations in yearly outlay of a British school in 1981, 1991, and 2001.
Overall, it is clear that teachers’ salaries had the largest proportion of spending in all three years whereas insurance accounted for the lowest amount of money.
To begin, teachers’ wages allocated 40% of expenditure in 1981 before it rose modestly to 50% in 1991. By the year 2001, the figure for teachers’ income declined slightly to 45%. In contrast, insurance constituted 2% of the annual spending at the start and grew minimally to 3% by 1991. The following 10 years it increased to 8%, which is 4 times larger than its initial proportion.
Regarding the other sectors of expenses, in 1981 the outgoings on furniture and resources were identical and made up 15% of the yearly expenditure. However, by 1991 money spent on resources like books increased faintly to 20%, while the figure for furniture and equipment dropped to 5%. In 2001, the outlay on furniture grew substantially to 23% at the expense of resources, which reduced to 9%. When it comes to the percentage of other workers’ earnings, it started off with 28% in 1981 and decreased slightly to 22% by 1991 before reaching its final value of 15% by the end of the selected period.
