The pie chart presents a comparison of the sizes of primary schools in four Australian states, namely New South Wales, South Australia, Australia Capital Territory, and Western Australia in 2010.
Overall, classes containing 21 to 25 students were by far the most popular size of classes, except for South Australia, while classes having over 30 students were a rarity in these areas. Notably, class distribution in Australia Capital Territory showed great differences throughout the period.
Regarding New South Wales and South Australia, the figures for classes having 20 or less than 20 students in New South Wales stood at 26%, which was 10% lower than that for those in South Australia. In addition, the percentage of primary-level classes comprising 21-25 students in New South Wales experienced 37% and 33% respectively, which were higher than that in South Australia (33% and 28% consecutively). In particular, the statistics for the biggest class size in both states were the same, each standing at only 4%.
Moving to the remaining states, in Australia Capital Territory, there were 38% of the proportion for classing having no more than 20 students, followed by 26% in Western Australia. Classes consisting of 21-25 students in Australia Capital Territory accounted for just over half of all sizes listed, compared to 42% in Western Australia. Furthermore, a reverse pattern can be seen in classes with 26-30 students, while the value for Australia Capital Territory made up one-tenth of the total, which was approximately two times lower than that for Western Australia; similarly, the former witnessed a mere 1% in the figures for largest class size, the latter was fivefold higher.
