According to the 2012 census the population of Sri Lanka was 20,359,439, giving a population density of 325/km2. ^[7] The population had grown by 5,512,689 (37.1%) since the 1981 census (the last full census), equivalent to an annual growth rate of 1.1%. ^[7] 3,704,470 (18.2%) lived in urban sectors - areas governed by municipal and urban councils. ^[8]

5,131,666 (25.2%) of the population were aged 14 or under whilst 2,525,573 (12.4%) were aged 60 or over, leaving a working age (15-59) population of 12,702,700. ^[9] The dependency ratio was 60.2%. ^[7] The mean age was 32 years and the median age was 31 years. ^[7] The sex ratio was 94 males per 100 females. ^[7] The fertility rate for married females aged 15 or over was 2.65 live births. ^[10] There were 5,264,282 households, of which 3,986,236 (75.7%) were headed by males and 1,278,046 (24.3%) were headed by females. ^[7]

Of the 15,227,773 aged 15 or over, 10,322,105 (67.8%) were married, 3,927,602 (25.8%) were never married, 792,947 (5.2%) were widowed and 185,119 (1.2%) were divorced or separated. ^[11]

Of those aged 15 or over, 7,857,370 (51.6%) were economically active, 4,199,558 (27.6%) did housework, 1,431,105 (9.4%) were students, 914,934 (6.0%) were unable to work and 346,084 (2.3%) were pensioners. ^[12] 521,938 (6.6%) of the economically active were unemployed. ^[7] 604,540 Sri Lankans were living aboard for more than six months but were intending to return to Sri Lanka, mostly in the Gulf states (373,050 61.7%). ^[13]

The overall literacy rate for those aged 10 and over was 95.7% but amongst those living in the estate sector it was only 86.1%. ^[14] Of the 18,615,577 aged 5 or over, 499,563 (2.7%) had received a higher education qualification, 2,293,841 (12.3%) had passed G.C.E. A/L, 3,159,402 (17.0%) had passed G.C.E. O/L and 700,419 (3.8%) had no formal schooling. ^[15] The remaining 11,962,352 (64.3%) had left school with no qualifications or were currently at school. ^[15]

Sri Lanka's population is aging faster than any other nation in South Asia and has the fifth highest rapidly growing population of older people in Asia after China, Thailand, South Korea and Japan. ^{[16] [17] [18]} In 2015, Sri Lanka's population aged over 60 was 13.9%, by 2030 this will increase to 21% and by 2050 this number will reach 27.4%. ^{[17] [18]} Sri Lanka's rapidly growing older population has ignited concerns of the socio-economic challenges that the country will face because of this. ^[19]

Ethnicity

Majority ethnicity by DS Division according to 2012 census

The Sinhalese make up 74.9% of the population (according to 2012 census) and are concentrated in the densely populated south-west and central parts of the island. ^[20]

The Sri Lanka Tamils, who live predominantly in the north and east of the island, form the largest minority group at 11.1% (according to the 2012 census) of the population. ^[20]

The Moors, descendants of Arab + Indian traders and native Sri Lankan Tamils, form the third largest ethnic group at 9.3% of the population. ^[20] These Tamil-speaking Muslims are mostly concentrated in urban areas in the southern parts of the island with substantial populations in the Central and Eastern provinces. During times of Portuguese colonization, Moors were persecuted, and many forced to retreat to the central highlands and the eastern coast.^{[ citation needed ]}

There are also Indian Tamils who form a distinct ethnic group comprising 4.1% of the population. ^[20] The British brought them to Sri Lanka in the 19th century as tea and rubber plantation workers, and they remain concentrated in the "tea country" of south-central Sri Lanka. The Indian Tamils of Sri Lanka were considered to be "stateless" and over 300,000 Indian Tamils were deported back to India, due to the agreement between Sri Lanka and India in 1964. ^[21] Under the pact, India granted citizenship to the remainder, some 200,000 of whom now live in India. Another 75,000 Indian Tamils, who themselves or whose parents once applied for Indian citizenship, now wish to remain in Sri Lanka. The government has stated these Tamils will not be forced to return to India, although they are not technically citizens of Sri Lanka. By the 1990s most Indian Tamils had received Sri Lankan citizenship, and some even were not granted Sri Lankan citizenship until 2003. ^{[21] [22]}

Smaller minorities include the Veddas, the indigenous people of Sri Lanka; Malays who descend from Austronesian settlers; the Burghers, who are descendants of European colonists, principally from Portugal, the Netherlands and, the UK; the ethnic Chinese migrants who came to the island in the 18th and 19th centuries; and the Kaffirs, a small population who are descended from Africans.

Languages

Main article: Languages of Sri Lanka

A multi-lingual road sign

Sinhala, an Indo-Aryan language, is the first language of Sinhalese people.

Tamil, a Dravidian language, is the first language of native Sri Lankan Tamils. Tamil is also the first language of the majority of Sri Lankan Moors and the Indian Tamils - according to the 2012 census 98% of Sri Lankan Moors could speak Tamil but only 59% could speak Sinhala. ^[31]

English is fluently spoken by approximately 23.8% ^[32] of the Sri Lanka's population, and widely used for official and commercial purposes.

Malays speak Sri Lanka Malay, a Creole language mixing Sinhala, Tamil and Malay. Many of the Burghers speak Sri Lankan Indo-Portuguese although its use has declined and the majority now speak Sinhala. ^[31] The Veddas speak Vedda, a Creole language closely based on Sinhala. Use of English has declined since independence, but it continues to be spoken by many in the middle and upper middle classes, particularly in Colombo. According to the 2012 census 24% of the population could speak English. ^[31] The government is seeking to reverse the decline in the use of English, mainly for economic but also for political reasons. According to the constitution Sinhala and Tamil are official languages whilst English is the link language. ^[33]

Notes

1. Non-scientific census of the whole island.
2. Indian Tamils were only classified as a separate ethnic group from 1911 onwards. Prior to this they were included with Sri Lankan Tamils.
3. Indian Moors were only classified as a separate ethnic group from 1911 to 1971. Prior to 1911 they were included with Sri Lankan Moors. After 1971 they were included with Others.
4. The 1941 Census was postponed due to World War II.
5. The 1951 Census was postponed due to a shortage of paper at the time.
6. 2001 Census was only carried out in 18 of the 25 districts. Inclusion of data would be misleading.
7. The official census dates for the 2011 Census was 20 March 2012.
8. Since the outbreak of hostilities between the government and armed Tamil separatists in the mid-1980s, several hundred thousand Tamil civilians have fled the island and more than 200,000 Tamils have sought refuge in the West (July 2010 est.) Aside from such migrants, there is an estimated 1.7 million Sri Lankans who are employed abroad (2010 est.), through which Sri Lanka earned USD 4.1 billion in annual worker remittances in 2010. Such remittances are a key source of foreign exchange for Sri Lanka.
9. These figures are based on the 2001 census which was only carried out partially in the Northern and Eastern provinces, where the majority of Sri Lankan Tamils and Hindus live. Therefore the Sri Lankan Tamil and Hindu percentage is grossly understated. The Sri Lankan government estimates that the Tamils (Sri Lankan and Indian) account for 18% of the population.
10. English is commonly used in government and is spoken competently by about 10% of the population as second language.
