The statistic shows the total population of South Korea from 2020 to 2024, with projections up until 2030. In 2024, the total population of South Korea was about 51.75 million people. Population of South Korea South Korea, also called Republic of Korea, has one of the highest population densities worldwide, i.e. a very high number of inhabitants per square kilometer. However, this does not equal bad standard of living; on the Human Development Index, which ranks countries by their level of living standards using key factors, such as unemployment rate, literacy rate, fertility and mortality rates, etc., South Korea is among the highest-ranked countries. When looking at the aforementioned key factors, South Korea indeed seems to offer a fairly stable environment for its inhabitants, economically and demographically: The country’s unemployment rate has been relatively steady for the past decade, its gross domestic product (GDP) is constantly increasing, and it is among the countries with the highest trade surplus worldwide. As for standard of living, life expectancy at birth in South Korea is among the highest worldwide – South Korea is even mentioned in a recent ranking of the best birthplaces for children. Despite the high population density, South Korea is now one of the countries with the lowest fertility rates, i.e. the number of babies born by women of childbearing age. This apparent discrepancy could be explained by a high number of immigrants coupled with the aforementioned high life expectancy.

Declining birth rate Several factors are contributing to the expected demographic changes in South Korea. Firstly, the birth rate has been declining for years. As of 2024, South Korea had the lowest fertility rate in the world. This trend continues despite the efforts of successive governments to encourage young people to have children. An increasing number of South Korean women are prioritizing their careers, often choosing to focus on work rather than starting a family at a young age. While the employment rate for South Korean women is still lower than that of men, it has steadily risen over the past decade. Increase in life expectancy Secondly, life expectancy in South Korea has steadily increased due to improved living standards and healthcare. The average life expectancy at birth for South Koreans has risen from less than 75 years to almost 83 years over the past twenty years.
