Sri Lanka Population 2018

20,941,515

Sri Lanka may seem like a small island lying southeast of India. However, it has a significant population of 20.95 million in 2018 (down from 21,481,334 in 2013), with the most dense areas lying in the urban areas such as the capital, Colombo, and other large cities that are also the industrial and economic hubs of the country. It is growing at a rate of 0.913% annually and houses people from many different ethnicities and religions, which gives the country a multi-cultural and multi-ethnic identity.

Sri Lanka hosts a dynamic age structure that includes a very large age bracket of 25-54 year old individuals dominating the country. Around 42.6% of the population lies in that age bracket. Even though Sri Lanka is a developing economy, such a large working population is allowing it to pursue development projects and create a large number of jobs that can utilized by its inhabitants. This is not only helping many people to support their families, but is also helping Sri Lanka’s economy grow steadily in the last few years.

Moreover, the median age of people in Sri Lanka is estimated to be 31.1 years, with the median age of men being 30.1 years while females have a median age of 32.2 years. Furthermore, Sri Lanka has a high life expectancy of 75.94 years, with a male life expectancy at 72.43 years and female life expectancy at 79.59 years. This is also why 9.1% of the country's population is in the 54-65 year age bracket, while 8.1% of its population is above the age of 65. An estimate of the number of deaths each year in the Sri Lanka lies at 5.96 deaths per a population of 1000 people.

Sri Lanka Birth Rate

On the other hand, due the large number of youngsters in the country, the marriage rates have only gotten higher in the last few decades. The great number of marriages have also resulted in a greater rate of births as well. The birth rate in Sri Lanka has risen in the last few years to around 17.04 births per population of 1000 people. This is also why the population in the 0-14 year old age bracket makes up 24.1% of the total population.

Sri Lanka is a country of multiple ethnicities, but the two most prominent are the Sinhalese and the Sri Lankan Tamils. The Sinhalese make up around 75% of the total population and are concentrated in the central and southwestern parts of the country. The Tamils make up around 11.9% of the total population and are thus the largest minority present in the country. The Sinhalese are predominantly Buddhist, and thus it is the major religion in the country, followed by Hinduism, which is actively practiced by the Tamils. The next most popular religion is Christianity, especially among the Burgher population.

Sri Lanka is a developing country with a lot of potential to grow if it can utilize its large work force and provide job and development opportunities for them. The country is steadily growing and needs to utilize its resources more carefully to sustain its development for the future.
