The bar chart gives information about the average size of primary schools and lower secondary schools in six countries, and comparing these data with the world average class size in 2006.
It is obvious that South Korea had a considerable number of students in both primary schools and lower secondary schools, which was higher than other countries. In contrast, Iceland had the lowest number of students in both categories, and less than the world average class size.
As can be seen, more than a third of students who aged between 5 and 16 studied at South Korea, and surpassed the world average class size. Following behind, Japan made up more than a fifth of students, (27% of primary schools and 32% of lower secondary schools). Both UK and Denmark the average size of lower secondary schools was lower than primary schools.
Like Japan, in Mexico the the average class size in secondary schools was 32%, while the size of primary school stood at 21%. In Iceland less than a fifth of students attended in primary and lower secondary schools. World Average category obtained around 25% of students in total, which was higher than UK, Denmark, and Iceland, but lower than South Korea, Japan, and Mexico just in lower secondary schools.
