United States Department of State, 2012 Report on International Religious Freedom - Indonesia, 20 May 2013, available at: http://www.refworld.org/docid/519dd4bca7.html [accessed 10 June 2013].
The constitution provides for religious freedom, but some laws and regulations restrict it. The government generally respected religious freedom for the six officially recognized religions, but not for groups outside those six religions, or groups within those six religions that espoused interpretations that local or national leaders deemed deviant or blasphemous.
The trend in the government's respect for religious freedom did not change significantly during the year; however, as in previous years, the government sometimes failed to protect the rights of religious minority groups. There were reports that police collaborated with hard-line groups against members of sects they deemed to be "deviant" when enforcing laws and regulations that limit religious freedom.
In some instances, government security forces failed to act when radical non-state actors attacked minority sects. There were reports that government officials and police witnessed the coerced conversion of dozens of Shia followers to Sunni Islam in East Java.
Local governments continued to block construction of houses of worship by minority groups within their communities and the national government failed to enforce two Supreme Court decisions in favor of construction permits for two Christian churches. During the year, a number of regional governments enforced decrees limiting or banning the free practice of Ahmadi Muslims.
Section I. Religious Demography
According to the 2010 government census, the most recent available, the population is approximately 237 million. Approximately 87 percent of the population is Muslim, 7 percent Protestant, 3 percent Roman Catholic, and 1.5 percent Hindu. Other religious groups (Buddhism, followers of traditional indigenous religions, Confucianism, other Christian denominations, and those who did not respond to the census question) comprise approximately 1.25 percent of the population.
The country's Muslim population is overwhelmingly Sunni. Of the more than 207 million Muslims, an estimated one to three million are Shiites. Many smaller Muslim groups exist, including approximately 200,000-400,000 members of the Ahmadiyya Muslim Community.
An estimated 20 million people, primarily in Java, Kalimantan, and Papua, practice various traditional belief systems, often referred to collectively as "Aliran Kepercayaan." There are approximately 400 different Aliran Kepercayaan communities throughout the archipelago. Many combine their beliefs with one of the government-recognized religions and register under that recognized religion.
