Demographics

he population of Indonesia according to the 2010 national census is 237.6 million, with 58% living on the island of Java, the world's most populous island. Despite a fairly effective family planning program that has been in place since the 1960s, the population is expected to grow to around 254 million by 2020 and 288 million by 2050.
Most Indonesians are descended from Austronesian-speaking peoples whose languages can be traced to Proto Austronesian (PAn), which possibly originated in Taiwan. Another major grouping are Melanesians, who inhabit eastern Indonesia. There are around 300 distinct native ethnicities in Indonesia, and 742 different languages and dialects. The largest ethnic group is the Javanese, who comprise 42% of the population, and are politically and culturally dominant. The Sundanese, ethnic Malays, and Madurese are the largest non-Javanese groups. A sense of Indonesian nationhood exists alongside strong regional identities. Society is largely harmonious, although social, religious and ethnic tensions have triggered horrendous violence. Chinese Indonesians are an influential ethnic minority comprising 3-4% of the population. Much of the country's privately owned commerce and wealth is Chinese-Indonesian-controlled, which has contributed to considerable resentment, and even anti-Chinese violence.
