Sri Lanka has a diverse population. The Sinhalese community forms the majority of the population (74%) with Tamils (18%) who are mostly concentrated in the north and east of the island, forming the largest ethnic minority. Other communities include the Muslims. Among Tamils, there are two sub-groups. The Tamil natives of the country are called ‘Sri Lankan Tamils’ (13 %). The Tamils, who were brought as indentured labourers from India by British colonists to work on estate plantations are called the ‘Indian Origin Tamils’ (5%). Most of the Sinhala-speaking people are Buddhists, while most of the Tamils are Hindus or Muslims. There are about 7 per cent Christians, who are both Tamil and Sinhalese.
