The provided pie charts compare the class sizes in primary schools across four distinct regions in Australia during the year 2010.
Overall, it can be clearly seen that the percentage of classes with 21-25 students accounted for the majority of primary schools in most areas, while classes with 30 students or more made up an unnoticeable proportion.
In 2010, regarding the first two charts above, New South Wales and South Australia, classes with 30 students or more also accounted for 4%. Looking more closely at South Australia, it is obvious that this chart was different from the other three charts because the proportion of classes with 20 students or fewer comprised the largest at 36%, while this rate decreased by 10% in New South Wales. Classes with 26-30 students in New South Wales and South Australia occupied 33% and 28%, respectively. The percentage of classes of 21-25 students in New South Wales was higher than in South Australia, standing at 37%, while South Australia had just 33%.
At the same time, according to the last two charts below, Australia Capital Territory and Western Australia, although classes with 30 students or more in Australia Capital Territory were smaller than in the other three charts, standing at 1%, classes with 21-25 students took up just over half at 51% and were the highest proportion. Meanwhile, classes with 30 students or more and 21-25 students in Western Australian classrooms were 5% and 42%, respectively. Classrooms with 26-30 students in Australia Capital Territory were at 10%, while this scale in Western Australian classrooms increased by 17%. The class sizes of under 20 students accounted for 38% in the capital region, making this scale higher than the other three pie charts. This figure in Western Australian classes was 12% smaller than in the capital.
