The pie charts compare the capacity of primary class rooms in four states in Australia in 2010.
Overall, classes containing 21-25 students took up the majority of primary class rooms, except for South Australia, where it was those with 20 students or less. Conversely, the proportion for over 30 students classes was considerably lower than in all other classes.
Take a look at New South Wales and Western Australia, both states share the same paternity. More specifically, the percentage of 21-25 students per class surpassed the others, amounting to 37% and 42% respectively. However, while New South Wales classrooms with 26-30 pupils (at 33%) have a noticeable gap of 7% when compared to those with less than 21, it was relatively the same in Western Australia, the former being 27% and the latter being 26%. Lastly, the most uncommon classes in the two states were those have over 29 students, at 4% and 5% respectively.
Turning to Australia Capital Territory, classrooms with 21-25 students covered over half the chart, counting up 51%, 13% higher than those with fewer than 21. 10% was the figure for 26-30 students, which was 10 times greater compared to that of over 29 students. As for South Australia, classes with a size of 20 students or less were dominant, with a percentage of 36. Taking up one-third of the chart was the figure for 21-25 students, 5% lower than that was classes containing 26-30 students. Ultimately, classrooms with the capacity of 30 students or more occupied a modest amount of 4%
