The provided figure contains pie charts displaying the size of classes in primary schools in four Australian states: New South Wales, South Australia, Australia Capital Territory, and Western Australia.
In New South Wales, 37% of primary school classes contain 25-30 students; a slightly smaller percentage of classes contain more than 30 students (33%). In South Australia, a similar trend is apparent; 33% of classes have 25-30 students, and 28% of classes contain more than 30 students. Additionally, the proportion of classes that have 21-25 students and under 20 students in both states are similar, totaling 26% and 4% in New South Wales, and 35% and 4% in South Australia respectively.
Western Australia and the Australian Capital Territory display dramatically different trends. In both regions, a significant percentage of classes have 25-30 students, at 51% in the Australian Capital Territory and 42% in Western Australia. However, the proportion of classes with more than 30 students are significantly disparaged between the two states: 10% in the Australian Capital Territory, and 25% in Western Australia. Interestingly, the percentage of classes with 21-25 students in Western Australian and New South Wales are equal; this trend is also observed between the Australian Capital Territory (38%) and South Australia (35%).
