Given is the bar chart which compares the average class size of two types of schools in six specific nations, including South Korea, Japan, the United Kingdom, Denmark, Mexico, and Ireland, with the world average statistics in 2006.
Overall, it is noticeable that both types of schools in South Korea had the biggest class size compared to other countries, whereas Ireland had the smallest class size. Specifically, classes in lower secondary schools in Mexico generally had more students than those of primary schools.

There were more than 35 students in classes in Korean lower secondary schools, with just under 35 students in primary school classes. Similarly, there were approximately 30 students in classes in Japanese lower secondary schools, while its primary school classes had just over 25 students. When it comes to the figures for Mexico, the class size in lower secondary schools almost doubled that in primary schools.
In contrast, the class size in primary schools was larger than that in lower secondary schools in the United Kingdom and Denmark, with just a marginal difference between the numbers of students, about 2 students. In addition, both types of schools in Ireland had under 20 students per class.
