Demographics

Muslims constitute a majority in most regions of Java, Sumatra, West Nusa Tenggara, Sulawesi, coastal areas of Kalimantan, and North Maluku. Muslims form distinct minorities in Papua, Bali, East Nusa Tenggara, parts of North Sumatra, most inland areas of Kalimantan, and North Sulawesi. Together, these non-Muslim areas originally constituted more than one third of Indonesia prior to the massive transmigration effort sponsored by the Suharto government and recent spontaneous internal migration.
Internal migration has altered the demographic makeup of the country over the past three decades. It has increased the percentage of Muslims in formerly predominantly Christian eastern parts of the country. By the early 1990s, Christians became a minority for the first time in some areas of the Moluccas. While government-sponsored transmigration from heavily populated Java and Madura to less populated areas contributed to the increase in the Muslim population in the resettlement areas, no evidence suggests that the Government intended to create a Muslim majority in Christian areas, and most Muslim migration seemed spontaneous. Regardless of its intent, the economic and political consequences of the transmigration policy contributed to religious conflicts in Maluku, Central Sulawesi, and to a lesser extent in Papua.

Organizations

The leading national "modernist" social organization, Muhammadiyah, has branches throughout the country and approximately 30 million followers. Founded in 1912, Muhammadiyah runs mosques, prayer houses, clinics, orphanages, poorhouses, schools, public libraries, and universities. On February 9, Muhammadiyah's central board and provincial chiefs agreed to endorse the presidential campaign of a former Muhammadiyah chairman. This marked the organization's first formal foray into partisan politics and generated controversy among members.
Nahdlatul Ulama (NU), the largest "traditionalist" social organization, focuses on many of the same activities as Muhammadiyah and indirectly operates a majority of the country's Islamic boarding schools. Claiming approximately 40 million followers, NU is the country's largest organization and perhaps the world's largest Islamic group. Founded in 1926, NU has a nationwide presence but remains strongest in rural Java. The Islam of many NU followers has heavy infusions of Javanese culture, and followers tend to reject a literal or dogmatic interpretation of Islamic doctrine. Many NU followers give great deference to the views, interpretations, and instructions of senior NU religious figures, alternately called "Kyais" or "Ulama." The organization has long advocated religious moderation and communal harmony.

Membership of the Indonesian Islamic Propagation Institute(LDII) continues to grow
A number of smaller Islamic organizations cover a broad range of Islamic doctrinal orientations. At one end of the ideological spectrum lies the controversial Islam Liberal Network (JIL), which aims to promote a pluralistic and more liberal interpretation of Islamic thinking. Equally controversial are groups at the other end of this spectrum such as Hizbut Tahrir Indonesia (HTI), which advocates a pan-Islamic caliphate, the Indonesian Mujahedeen Council (MMI), which advocates implementation of Shari'a as a precursor to an Islamic state, and the sometimes violent Front Pembela Islam (FPI). Countless other small organizations fall between these poles.
Separate from the country's dominant Sunni Islam population, a small minority of persons subscribe to the Ahmadiyya interpretation of Islam. However, this group maintains 242 branches throughout the country. In 1980 the Indonesian Council of Ulamas (MUI) issued a "fatwa" (a legal opinion or decree issued by an Islamic religious leader) declaring that the Ahmadis are not a legitimate form of Islam.
In addition there are small numbers of other messianic Islamic groups, including the Malaysian-affiliated Darul Arqam, and the syncretist Indonesian Jamaah Salamulla group (also called the Salamulla Congregation or God's Kingdom). Its leader, Lia Eden, is currently facing charges of disdaining Islam and many Islamic organizations in Indonesia consider them as a heretical form of Islam.
