Republic of Korea population 2020

During 2020 Republic of Korea population is projected to increase by 248,825 people and reach 51,659,009 in the beginning of 2021. The natural increase is expected to be positive, as the number of births will exceed the number of deaths by 186,619. If external migration will remain on the previous year level, the population will be increased by 62,206 due to the migration reasons. It means that the number of people who move into Republic of Korea (to which they are not native) in order to settle there as permanent residents (immigrants) will prevail over the number of people who leave the country to settle permanently in another country (emigrants).

Republic of Korea age structure

As of the beginning of 2020 according to our estimates Republic of Korea had the following population age distribution:

15.7 72.9 11.4

- 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 Republic of Korea population pyramid has a contracting type. This type of pyramid is more common for highly developed countries with low birth and death rates. Usually countries with such kind of population age distribution model have long life expectancy, high level of education and good health care.

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 Republic of Korea is 37.1 %.

The value of 37.1 % 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 Republic of Korea 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 Republic of Korea 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 Republic of Korea is 21.5 %.

Aged dependency ratio

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

Aged dependency ratio in Republic of Korea is 15.7 %.

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). external link
