The three pie charts show changes in the expenditure of a school on various aspects in three particular years.
Overall, the proportion of expenses on teachers' salaries was highest in all three years with insurance receiving least money. Moreover, the percentage of other categories saw some sharps and downs, though the index for other workers' payments registered a significant decline in the same years.
Although the proportion of total spending on teachers' salaries went up to 50 percent in 1991 from 40 percent in 1981, then the figure fell to 45% at the end of the period.
On the other hand, the same index for other workers' pays declined significantly with figure falling from 25% in 1981 to 15% in 2001.
Although there were some changes in the costs of the other aspects, the proportion of insurance, which equaled to only 2% in the beginning, grew four times still staying the lowest in 2001.
