Indonesia obviously has many big islands. Why is Java the fifth most populous island?

Because the living conditions of Guawa Island are the best compared with other big islands, although Guawa Island is mostly mountainous, it is precisely because of this that Guawa Island basically has no swamp and fertile land, so it is more suitable for living in an agricultural country like Indonesia. Moreover, Guawa Island does not belong to the tropical rain forest climate, so there will be no animals that eat crocodiles, which attracts many Indonesian residents to live in Guawa Island, and its capital is also located in Guawa Island.

The largest island in Indonesia is Irian Island, which is the second largest island in the world. However, because there are too many swamps and tropical climate, most people don't want to live here, which is not conducive to agricultural development. The climate here is unbearable for everyone. Kalimantan island, Indonesia's second largest island, has many rivers and a tropical rain forest climate, so crocodiles and other terrible animals can be seen everywhere. So it is not suitable for residents to live here.

Sumatra, the third largest island, also has many rivers. Although the plain area is large, most of it is swamp area, which is not suitable for farming, so most Australian residents will not choose to live here. Sulawesi, the fourth largest island, is actually separated from kalimantan island, so most places like kalimantan island are uninhabitable.

Therefore, in comparison, Guawa Island, ranked fifth, is more popular with residents. Although Guawa Island is unstable, there may be an earthquake, but Guawa Island's climate and agricultural development prospects are more conducive to residents' lives, so the population is concentrated here.
