The bar chart illustrates the average class size in six countries in 2006, divided into primary schools (ages 5-10) and lower secondary schools (ages 13-16). It also compares these figures with the world average.
Overall, South Korea and Japan had the largest class sizes in both primary and secondary schools, while Denmark and the United Kingdom reported the smallest. Mexico’s figures were above the global average, whereas Iceland’s were below.
In South Korea, the average primary class size was around 35 students, while in lower secondary it was slightly lower, at about 32. Japan followed a similar pattern, with around 29 students in primary and 35 in secondary. By contrast, Denmark had the smallest classes, with fewer than 20 students in both levels.
Mexico recorded class sizes of approximately 30 in primary and 35 in secondary, both higher than the world averages of around 25 and 24 respectively. Iceland and the UK remained consistently below the global figures, with about 20-23 students per class.
In summary, Asian countries tended to have larger classes, whereas European nations reported smaller ones.
