The pie charts compare the expenditure of a school in the UK in three different years over a 20-year period,from 1981 to 2001.
Overall, it is clear that teacher’s salaries made up the largest proportion of the school’s spending in all three years(1981,1991,and 2001). By contrast, insurance was the smallest cost in each year.
In 1981, 40% of the school’s budget went on teacher’s salaries. This figure rose to 50% in 1991, but fell again by 5% in 2001. The proportion of spending on other worker’s wages dropped steadily over the 20-year period, from 28% of the budget in 1981 to only 15% in 2001.
Expenditure on insurance stood at only 2% of the total in1981, but reached 8% in 2001. Finally, the percentages for resources and furniture/equipment fluctuated. The figure for resources was highest in 1991, at 20%, and the proportion of spending on furniture and equipment reached its peak in 2001, at 23%.
