Other faiths remained largely stable in their share of the population.

There are monasteries and Dharma centres from all three major traditions of Buddhism in Singapore: Theravada, Mahayana, and Vajrayana. Most Buddhists in Singapore are Chinese and are of the Mahayana tradition, missionaries having come into the country from China for several decades. However, Thailand's Theravada Buddhism has seen growing popularity among the populace (not only the Chinese) during the past decade. The religion of Soka Gakkai International, a Japanese Buddhist organisation, is practised by many people in Singapore, and mostly by those of Chinese descent. Tibetan Buddhism has also made slow inroads into the country in recent years.
