The pie charts compare the expenditure of a school in the UK in three different years over a 20-year period.

The supplied pie charts illustrate schools’ spending in three various years (1981, 1991 and 2001) throughout 2 decades in the UK. Units are measured in percentage.

Overall

, it is obvious that the school spent a little amount of money on insurance almost in three years.

In contrast

, the majority of expenditures represented teachers’ salaries

together with

furniture and equipment showing roughly the same proportion in all three pie charts. It is conspicuous that, the greatest spending was on teachers’ salaries in 1991 culminating at 50%, the highest of any category in any year. Meanwhile,

this

figure showed an all-time low index in furniture and equipment accounting for a mere 5%. It is interesting to note, that proportion of other workers’ salaries experienced second place in spending in both 1981 and 1991, representing 28% and 22% respectively,

whereas

the school spent more money on furniture and equipment, which accounted for 23% in 2001 than in previous decades.
