Sri Lanka population 2017

During 2017 Sri Lanka population is projected to increased by 104 793 people and reach 20 979 811 in the beginning of 2018. The natural increase is expected to be positive, as the number of births will exceed the number of deaths by 203 740. If external migration will remain on the previous year level, the population will be declined by 98 948 due to the migration reasons. It means that the number of people who leave Sri Lanka to settle permanently in another country (emigrants) will prevail over the number of people who move into the country (to which they are not native) in order to settle there as permanent residents (immigrants).

Population dynamics in 2017

According to our estimations, daily change rates of Sri Lanka population in 2017 will be the following:

The population of Sri Lanka will be increased by 287 persons daily in 2017.

Population of Sri Lanka 2016

As of 1 January 2017, the population of Sri Lanka was estimated to be 20 875 018 people. This is an increase of 0.50 % (104 269 people) compared to population of 20 770 749 the year before. In 2016 the natural increase was positive, as the number of births exceeded the number of deaths by 202 723. Due to external migration, the population declined by 98 453. The sex ratio of the total population was 0.974 (974 males per 1 000 females) which is lower than global sex ratio. The global sex ratio in the world was approximately 1 016 males to 1 000 females as of 2016. See also map of the world by sex ratio of total population.

Below are the key figures for Sri Lanka population in 2016:

Sri Lanka population density

Sri Lanka population density is 318.2 people per square kilometer as of February 2017. Density of population is calculated as permanently settled population of Sri Lanka divided by total area of the country. Total area is the sum of land and water areas within international boundaries and coastlines of Sri Lanka. The total area of Sri Lanka is 65 610 km2 according to the United Nations Statistics Division .

Sri Lanka age structure

As of the beginning of 2017 according to our estimates Sri Lanka had the following population age distribution:

24.9 67.2 7.9

- percentage of population under 15
- percentage of population between 15 and 64 years old
- percentage of population 65+

In absolute figures (estimate):

We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.

65+
15-64
0-14
male female

Note: The pyramid provided is not corresponding to data given above because the age groups have different number of years.

As we can see the Sri Lanka population pyramid has an expanding type. This type of pyramid is common for developing countries with high birth and death rates. Relatively short life expectancy, as well as low level of education and poor health care are also describe such kind of population age distribution model.

Age dependency ratio

Dependency ratio of population is a ratio of people who are generally not in the labor force (the dependents) to workforce of a country (the productive part of population). The dependent part includes the population under 15 years old and people aged 65 and over. The productive part of population accordingly consists of population between 15 and 64 years.

This ratio shows the pressure on productive population produced by the dependent part of population.

The total dependency ratio of population in Sri Lanka is 48.8 %.

The value of 48.8 % is relatively low. It shows that the dependent part of population is less than a half of the working part. In other words the working population (labor force) in Sri Lanka must provide goods for itself and cover expenditure on children and aged persons. And this part of population is less than 50% of working population. The value of less than 50% means that the pressure on productive population in Sri Lanka is relatively low.

Child dependency ratio

Child dependency ratio is a ratio of people below working age (under 15) to workforce of a country.

Child dependency ratio in Sri Lanka is 37.1 %.

Aged dependency ratio

Aged dependency ratio is a ratio of people above working age (65+) to workforce of a country.

Aged dependency ratio in Sri Lanka is 11.7 %.

Life expectancy

Life expectancy at birth is one of the most important demographic indicator. It shows the number of years a newborn infant would live assuming that birth and death rates will remain at the same level during the whole lifetime.

Total life expectancy (both sexes) at birth for Sri Lanka is 75.7 years.
This is above the average life expectancy at birth of the global population which is about 71 years (according to Population Division of the Department of Economic and Social Affairs of the United Nations).

Male life expectancy at birth is 72.2 years.
Female life expectancy at birth is 79.4 years.

Literacy of population

According to our estimates 14 517 498 persons or 92.64% of adult population (aged 15 years and above) in Sri Lanka are able to read and write. Accordingly about 1 153 796 adults are illiterate.

Literacy rate for adult male population is 93.63% (7 083 644 persons). 482 089 are illiterate.
Literacy rate for adult female population is 91.71% (7 433 853 persons). 671 708 are illiterate.

Youth literacy rates are 98.36% and 99.17% for males and females accordingly. The overall youth literacy rate is 98.76%. Youth literacy rate definition covers the population between the ages of 15 to 24 years.
