The 3 pie charts compare expenditures of one school in the UK in 1981, 1991 and 2001.

As it can be seen from the pie charts, the expenditures on insurance were increasing gradually from 2% in 1981 to 8 % by 2001 year.

Teachers` salaries have not been changed enormously and remained at 40-50 % of the school spending.

The expenses on furniture and equipment were constantly fluctuating with a sharp drop (from 15 % in 1981 to 5 % in 1991) and a significant rise to 23 % in 2001.

The resources (e.g. books) was a large part of school`s expenditures in 1981 and 1991(15 % and 20 % respectively), however this point of spending decreased considerably by 2001 year (9 %).

The salaries of other workers were reducing gradually from 28 % to 15 % in 2001.

Overall, the expenditures on the insurance, furniture and equipment in the school rose on account of the decrease of spending on resources and other workers` salaries.
