Population of Sri Lanka

The population of Sri Lanka in 2017 was estimated at 22.4 million. The country has seen a declining population growth in recent years. Population growth was 0.76 percent in 2017. However, the birth rate has been declining, and has contributed to a lower population growth. Life expectancy (in 2017) is 80.6 years for women and 73.5 years for men.

Population Composition

Nearly 75 percent of the population is Sinhalese and about 18 percent are Tamils. In addition, there are about 7 percent Moors (a Muslim people group with Arab roots). Of the indigenous peoples, the Witnesses, there is only a very small number left.

Sri Lanka’s ethnic relations have been conflicting for some time. After independence, the contradictions between Sinhalese and Tamils ​​increased, partly because the Sinhalese gained some advantages. The official language became Sinhalese, and Buddhism was adopted as the official state religion. This situation led to increased dissatisfaction among the Tamil minority and a Tamil radical movement called the Tamil Tigers (LTTE) grew and demanded an independent Tamil state. The conflict between Sinhalese and Tamils ​​led to civil war in the period 1983-2009. In 2009, the government declared it had defeated LTTE.

Population Patterns

The country’s average population density is high, averaging 308.2 residents per km2, but it varies from over 500 residents per km2 in the humid southwest of the island to below 60 in some districts in the east. Around 30 percent of the population lives in cities, after a continuous relocation from rural to urban, especially to the capital. The largest cities are Colombo, Gampaha, Kandy and Galle.


Official languages ​​are Sinhalese and Tamil. Also, the indigenous people, the Vedas, speak a dialect of Sinhalese, but some words of unknown origin point to a lost language. About 74 percent of the population speak Sinhalese, well over 18 percent Tamil (in the north and east). The Tamil dialects in Sri Lanka are archaic and the writing language is closer than the dialects in Tamil Nadu in India. English is used in administration. It is estimated that ten percent of the population is fluent in English.


About 70 percent of Sri Lankan people (mainly Sinhalese) are Buddhists and belong to the theravada school, about 16 percent (substantially Tamils) are Hindus, about 7.5 percent are Christians (about three-quarters Catholic) and about 8 percent are Muslims.

Buddhism is perceived as a fundamental part of national Sinhalese culture. There are around 6,000 monasteries and 30,000 monks and novices. Some religious centers gather believers from all the island’s religions, for example, the pilgrimage to Mount Adam’s Peak where Buddha (or Adam, or Shiva) should have left his footprint in stone, and to the center of the ecstatic cult of the god Kataragama on the southeast coast.
