South Korea in numbers
The UN counts 51,748,739 people in South Korea in mid-2023, which makes it the 29th-largest population of the 236 countries and areas the UN reports, and 0.64% of the world's people. That is 2.6 times its 1950 population of 19.8 million.
Its population peaked in 2020 at 51.9 million and has been falling since. The UN's medium projection has 21.8 million in 2100. The projection is uncertain: on 1 January 2100 the UN's 95% range runs from 9.4 million to 51.9 million.
Since 2019, more people have died here each year than have been born, and the UN's projection has that holding every year to 2100. Deaths also outnumbered births in 1950. The population still grew until 2020, because more people arrived than left.
The median age was 18.7 in 1950 and 45.5 in 2023; the projection has 60.8 in 2100. 18.3% of people were 65 or older in 2023, against 45.2% projected for 2100. The working-age population (15–64) peaked in 2017 at 37.6 million; in 2023 it was 36.6 million.
Among countries it ranks 29th in 2023, 47th in 2050 and 72nd in 2100. It is overtaken by Sudan in 2026, Uganda in 2026 and Iraq in 2030.

KOR · 1950–2100 · every age, every year
South Korea, every age in every year
Each column is a year and each row an age; the denser the ink in a cell, the more people. Everyone born in the same year climbs one 45° diagonal, so famines, baby booms and migration show up as streaks. Select a cell to follow its generation.
KOR · ages 15–64
Who does the work in South Korea
South Korea had the most working-age people it is ever expected to have in 2017: 37,641,900 people aged 15–64, against 36,583,300 in 2023.
aged 15–64 children under 15 aged 65 and over
How to read this: one orange square for each of 100 people aged 15–64 in 2023. Beneath them, teal for the children living alongside those 100 and violet for the people aged 65 or older.
Fewer than 50 dependants live alongside every 100 people aged 15–64 in 43 years: 1987–2029.
fewer than 50 dependants per 100 the same, projected 50 or more
How to read this: 1950 on the left, 2100 on the right; coloured in the years with fewer than 50 dependants per 100 working-age people, grey in the rest, hatched where that is a projection.
KOR · arrivals minus departures
Who arrives in South Korea, and who leaves
In 2020–2025 South Korea gains 64,794 people a year: everyone who arrives, minus everyone who leaves. The age at which that happens most is 20–24, at 31,927 a year more arriving than leaving.
more arrive than leave more leave than arrive
How to read this: each column is one age, youngest on the left. Above the line, in blue, are the ages gaining people; below it, in orange, the ages losing them. This is the UN's projection for 2020–2025 — the record of migration by age does not go back beyond 2020.
In the years that were counted, 1950–2023, the most it gained in one year was 308,037 (2014) and the most it lost was 270,754 (1991).
In 2024, 1,811,507 people living in South Korea had been born in another country, 4 of every 100 people there, against fewer than 1 in 1990.

Of every 100 babies born in South Korea in 2023, 65 a mother aged 20 to 34 and 35 a mother aged 35 or older. In 1950 it was 4 under 20 and 24 aged 35 or older.

Years in good health in South Korea
In South Korea, WHO puts the healthy years a newborn could expect in 2021 at 72.5 (95% range 71.6–73.1), out of 83.8 in all. The years in less than full health come to 11.3, above the world's 9.5.
74.1 in full health, 12.6 not: 86.7 years
70.7 in full health, 10.0 not: 80.7 years
a year in full health a year in less than full health
How to read this: each square is a year of life, each row ten years; filled squares are years in full health, rounded to whole years.
Women: 74.1 healthy years of 86.7. Men: 70.7 of 80.7.

How to read this: each square is 1,000 people, so the rows can be compared with one another. The last row is people from South Korea living in another country, wherever they are.
In 2025, 14,572 people asked for asylum in South Korea for the first time; 179 people from South Korea asked for asylum in another country. Of every 100 people from South Korea whose claims were decided that year, 0 were given protection. Who asks for asylum, and who is given it

Of every 100 people in South Korea in 2025, 76 lived in a city, 14 in a town or suburb and 10 in the countryside.

Nearly everyone has electricity at home (2024). 2.1 of every 100 do not use the internet (2024).
How to read this: one square for every hundredth person, coloured as the key shows. Because the rule behind the colours is the same everywhere, two countries' squares can be compared directly.
KOR · adults 25 and over · 2020
How far people in South Korea went in school
Of every 100 adults in South Korea in 2020, 2 never went to school and 81 finished upper secondary or went further.

Its people aged 15 to 64 were most numerous in 2020, the first year counted, and are never as many again in the middle projection; nor are the ones who finished upper secondary.
How to read this: the row is the adults (25 and over) shrunk to 100 people, coloured by how far each went in school, least schooling on the left. The Wittgenstein Centre's count, 2020.
