Why is Indonesia's population mainly distributed in Java?

The reasons why Indonesia's population is mainly distributed in Java Island:

1. Java Island is located in the core area of Indonesia, with a specific area of 138,7 square kilometers and a population of 145 million. It accounts for half of Indonesia's population. Fujian Province, which is close to Java Island in China, has a population of less than 4 million. The island is also the seat of Jakarta, the capital of Indonesia. So Java is also the political and economic center of Indonesia.

2. Geographical climate: Java Island is the most important rice grain producing area in Indonesia. It can be found that the areas with low forest coverage are mainly rice planting areas. Therefore, agricultural activities are also one of the reasons why Guawa Island has become the center of Indonesia.

3. The area of the calcareous red and yellow soil in Indonesia is about 51 million hectares. Because the soil formed earlier, the area of this soil in Java Island is less, and the fertility of the calcareous red and yellow soil is not high, which is not suitable for planting crops such as rice. The volcanic ash on Java Island has been covered for a relatively short time, and its fertility is very good, so it has become the main grain producing area in Indonesia, and it has also nurtured a large number of people, making Java Island the core of Indonesia.

Topography of Indonesia:

Indonesian islands are scattered, mainly including kalimantan island, Sumatra, Irian, Sulawesi and Java. There are many rugged mountains and hills in each island, only narrow plains along the coast, surrounded by shallow seas and corals.

in kalimantan island, the mountains extend from the middle to the west, with vast coastal plains and swampy south.

In Sumatra Island, the mountains run obliquely from northwest to southeast, with hills and a wide coastal alluvial plain on the northeast side of the mountains, and swamps in the east of the plain.

Sulawesi is mostly mountainous, with only a narrow plain along the coast.

Java Island, with plains in the north and lava plateaus and mountains in the south, is a vast basin between mountains.

Irian Island, with mountains in the west, is the highest mountain in Indonesia and the highest island peak in the world, puncak jaya, with an altitude of 53 meters, and a wide plain in the south.
