South Korea Demographics: Population Trends and Social Shifts
South Korea is currently navigating a profound demographic transition. Once characterized by rapid growth and a mid-century baby boom, the nation now faces some of the most significant population challenges in the world. From a plummeting fertility rate to a rapidly aging society, the statistical landscape of the Republic of Korea reflects broader socio-economic shifts.
As of 2024, the estimated population stands at 52,081,799, with a growth rate that has slowed to just 0.21%. This stabilization marks a sharp contrast to the mid-20th century, where the population expanded rapidly following the Korean War.

- Total Population: Approximately 52.1 million (2024 est.).
- Fertility Rate: 0.75 children born per woman, one of the lowest globally.
- Life Expectancy: 83.4 years on average (Female: 86.6, Male: 80.3).
- Age Structure: 19.3% of the population is aged 65 or older.
- Immigrant Share: 3.5% of the total population.
- Natural Increase: Currently negative, with deaths exceeding live births.
Population Growth and Historical Trends
The trajectory of South Korea's population has been shaped by significant historical events. Between 1930 and 1960, the population grew from roughly 13.9 million to nearly 25 million. This growth accelerated through the 1970s and 80s, peaking in the early 21st century before beginning to plateau.
The mid-20th-century baby boom (1955–1960) created a demographic bulge that is now moving into retirement, contributing to the current aging crisis. While the population passed the 50 million mark in 2012, recent data shows a trend toward stagnation and potential decline.
Fertility and Vital Statistics
The most pressing demographic concern is the Total Fertility Rate (TFR)—the average number of children born to a woman over her lifetime. In the early 1900s, the TFR was approximately 6.0. By 2024, this figure dropped to 0.75, well below the replacement level of 2.1.
Regional disparities exist within the country. Seoul reports the lowest TFR at 0.581, while regions like Chungcheongbuk (0.882) and Jeju (0.826) show slightly higher, though still critically low, rates.
Birth and Death Rates
The Crude Birth Rate (CBR) and Crude Death Rate (CDR) have converged. In 2024, the birth rate is estimated at 7 births per 1,000 population, while the death rate is slightly higher at 7.4 deaths per 1,000. This results in a negative natural increase, meaning the population would shrink without migration.
Age Structure and Life Expectancy
South Korea's population pyramid has shifted from a wide-base triangle to a top-heavy structure. The 15–64 age group (the working-age population) makes up 69.4% of the total, but the 65+ cohort is growing rapidly, now representing 19.3% of the population.
This shift is mirrored by a dramatic increase in life expectancy. In 1908, life expectancy was only 23.5 years; by 2020, it reached 83.5 years. Women generally outlive men, with a 2024 estimate of 86.6 years compared to 80.3 for males.

Migration and Ethnic Composition
To offset natural population decline, migration has become an increasingly important factor. The net migration rate is estimated at 2.6 migrants per 1,000 population. Foreign residents now make up 5.3% of the total population, with the largest groups originating from China, Vietnam, Thailand, and the United States.
Demographic Summary Table
| Indicator | Value |
|---|---|
| Total Population | 52,081,799 |
| Fertility Rate (TFR) | 0.75 |
| Life Expectancy (Avg) | 83.4 Years |
| Infant Mortality | 2.8 per 1,000 live births |

Social and Cultural Landscape
The population remains predominantly ethnic Korean, with Korean as the primary spoken language. Religiously, the society is diverse; approximately 51% of the population is irreligious, while 31% identify with Christianity and 15% with Buddhism.
Frequently Asked Questions
What is the current fertility rate in South Korea?
As of 2024, the total fertility rate is 0.75 children born per woman, which is among the lowest in the world.
Is the population of South Korea shrinking?
While the total population is around 52 million, the natural increase has become negative, meaning deaths now outnumber births. Growth is currently minimal (0.21%) and relies partly on migration.
How has life expectancy changed over time?
Life expectancy has risen dramatically from 23.5 years in 1908 to an average of 83.4 years in 2024.
Which region in South Korea has the lowest birth rate?
Seoul has the lowest total fertility rate in the country, recorded at 0.581.
What is the ethnic makeup of South Korea?
The vast majority of the population is ethnic Korean, though there is a growing foreign resident population, primarily from China, Vietnam, and Thailand.
