The three pie charts illustrate how total school expenditure was distributed among five categories in 1981, 1991 and 2001.
Overall, teachers’ salaries accounted for the largest proportion of spending in all three years, while insurance consistently represented the smallest share. Although most categories experienced fluctuations, expenditure on furniture and equipment rose noticeably by the end of the period.
In 1981, teachers’ salaries made up 40 percent of total spending, followed by other workers’ salaries at 28 percent. Resources and books, as well as furniture and equipment, each accounted for 15 percent, whereas insurance represented only 2 percent.
By 1991, the proportion allocated to teachers’ salaries had increased significantly to 50 percent. In contrast, spending on other workers’ salaries fell by six percentage points. While expenditure on resources and books rose to 20 percent, the figure for furniture and equipment declined sharply to 5 percent. Insurance remained minimal at 3 percent.
In 2001, teachers’ salaries fell slightly to 45 percent, although they remained the dominant category. Spending on furniture and equipment increased substantially to 26 percent, while resources and books dropped dramatically to just 5 percent. Other workers’ salaries declined marginally to 15 percent, and insurance continued to account for a very small share at 4 percent.
