The charts demonstrate the proportion of different primary school classes in four areas in Australia in 2010.
From the outset, the most common class size of primary schools in all states was 21 to 25 students except for South Australia, where the percentage of under 21 pupils class was highest. By contrast, the classes that had 30 students or more rarely appeared in this time frame.
Regarding Australia Capital and Western part, 21-25 students’ classes held the lion’s share of primary schools in two areas, with 51% and 42% respectively. With 38% of classes that had fewer than 21 pupils in the capital, these were much higher than 26% of the Western area. Meanwhile, 26-30 students’ classes in 2 states had a significant difference, Western Australia had 27%, which was 17% outnumbered that of Australia Capital Territory (10%). Over 29 students’ classes were least popular in 2 states, though that of the Western part was slightly superior to the Capital of this country, at 5% compared to 1%.
In terms of the remains, these areas shared the same data in the ratio of classes which had more than 29 students, at 4%. There was 37% of 21-25 students’ classes in New South Wales, making it the biggest share, whilst in South Australia, this figure only stood at second place. In the meantime, over 19 students in classes occupied above a quarter of total but that of the Southern part accounted for the largest percentage, with 36%.
