The population of Singapore is diverse, the result of considerable past immigration. Chinese predominate, making up some three-fourths of the total. Malays are the next largest ethnic group, and Indians the third. None of those three major communities is homogeneous. Among the Chinese, more than two-fifths originate from Fujian province and speak the Amoy (Xiamen) dialect, about one-fourth are Teochew from the city of Shantou in Guangdong province, and a smaller number are from other parts of Guangdong. Linguistic differences are less pronounced among the Malays, but the group includes Indonesians speaking Javanese, Boyanese, and other dialects. The Indian group is most diverse, consisting of Tamils (more than half), Malayalis, and Sikhs; it also includes Pakistani and Sinhalese communities. The Lutheran Church in Singapore is small but actively involved in developing and supporting mission work throughout Asia.
