Population distribution is uneven, with 60% living in just 7% of the land. The island of Java has about 140 million inhabitants (60% of the total population) while the larger Sumatra island has only about a third of its people. The government implemented a voluntary "transmigration" program to relocate poor landless people from Java, Bali and other densely populated islands to less densely populated ones providing them with land, houses, seed money and new opportunities to generate income. However, this program has met with criticisms. In 2001, ethnic violence broke out in Kalimantan as indigenous Dayaks forced out transmigrants from the island of Madura.
