Singapore has an area of 270 square miles (700 km2) and a total population of 5.31 million (as of June 2013), of whom 3.6 million are citizens or permanent residents. According to a 2000 government survey, 85 percent of citizens and permanent residents profess some religious faith. Of this group, 51 percent practice Buddhism, Taoism, ancestor worship, or other religious practice traditionally associated with the ethnic Chinese population. Approximately 15 percent of the population is Muslim, 15 percent Christian, and 4 percent Hindu. The remainder is composed of atheists, agnostics, and adherents of other religions including small Sikh, Jewish, Zoroastrian, and Jain communities. Among Christians, the majority of whom are ethnic Chinese, Protestants outnumber Roman Catholics by slightly more than two to one.
Approximately 77.8% of the resident population is ethnic Chinese, 14% ethnic Malay, and 7% ethnic Indian. Nearly all ethnic Malays are Muslim and most ethnic Indians are Hindu. The ethnic Chinese population is divided between Buddhism, Taoism, and Christianity, or is nonreligious.
