Indonesia has the world’s 4th largest population. It is made up of 1300 different ethnicities in 17,000 islands stretching over 3000 miles along the equator north of Australia. Official figures say that 87% of the more than 275 million confess Islam. The vast majority, however, are nominal Muslims and know very little about their religion. The claim of 11% confessing Christians seems inaccurate in the light of the steady growth of the Indonesian church.
Bahasa Indonesian is the national language, but 737 other languages are spoken. Traditional folkways are strong among all. Indonesia has many young families, over 40% of the population are under 25 years of age. Over 60% live in urban areas.
