Indonesia's 15 Richest Billionaires

Indonesia is a sprawling nation on the equator, towards the north east of the Indian Ocean. This country comprises more than 18,000 islands, making Indonesia the biggest archipelago in the world. In terms of total area, Indonesia is the 15th biggest country in the world. Their tropical climate and proximity between the Indian and Pacific ocean results in a hot, humid atmosphere through most of the country.

Geography aside, how's this part of the world doing on the world wealth scale?

According to a CIA report , the 254 million residents of Indonesia had a GDP of $1.285 trillion over the past year, which amounts to $5,200 per capita. Despite a strong GDP growth rate of 5.3%, Indonesia suffers from a variety of problems that lead to significant income inequality, such as corruption, inadequate economic regulations and infrastructure issues.

Indonesia's geographic location allows the country to produce valuable commodities that grow only in specific climates, such as coffee, rubber, plastics, palm oil and tobacco. In fact, the palm oil industry drives the wealth of almost half of the billionaires on this list. Other major sources of wealth are media companies, banks, holding companies, real estate development, construction and transportation.
