Korean Population: #1 Hard Truth About This Declining Statistic + Easy Vocabulary

Curious about the Korean population (or 인구 – ingu in Hangeul) and how it is distributed around the country? Stop your search and read this article, where I will tell you about the country’s population density and evolution over the last few years.

Based on my experience, the first time I stepped foot in South Korea, I also saw how the population seemed to be much older. It’s pretty much like the Japanese population, to be honest, and now I have statistics that back my opinion.

Both North Korea, or 조선 (Joseon), and South Korea, or 한국 (Hanguk), are following a declining trend in terms of their population. According to the United Nations publication “World Population Prospects: The 2022 Revision”, Korea’s population will decline to 61 million in 2070 after peaking at 78 million in 2022. This fact is mainly due to South Korea’s declining population, which has already been a case study by many experts. According to United Nations, South Korea’s downward trajectory that started in 2021 when it came to roughly 52 million will continue to drop to 38 million in 2070. North Korea will follow this projection and start its declining trajectory after peaking in 2023.

As if discussing this topic was not interesting enough, I’m also going to give you a series of vocabulary in Korean about the population that you’ll find super useful for your next discussion with your Korean friend about why the population is following this trend. Keep reading until the end and absorb all the information I have to give you!

Korean Fertility: A Case Study

South Korea’s population used to be relatively young. However, this younger population has become a smaller share of the total population in less than two decades. On the other side of the spectrum, the South Korean population over 65 has been growing at a concerning pace since 2010. Based on this, Korea is expected to become the country with the oldest population by 2070, reaching 46.4% of the population in this range. In a country where life expectancy is reaching 83.5 years, the high aging rate of South Korea’s population is a topic to be taken with care and seriousness.

South Korea is one of the planet’s most densely populated countries, with a density of 503 people per square kilometer. However, this was not a factor in what happened in 2021. In a surprising turn of events, South Korea’s population recorded its first-ever decline in total since 1949, coming down to roughly 52 million.

South Korea’s population decline and aging are primarily due to the declining fertility rate that has set records worldwide. South Korea became the first country in the world to see its total fertility rate fall below 1 percent. These records are negative as Korea is the second country in the world with the lowest fertility rate of 0.81 births per woman, just behind Hong Kong’s 0.75.

The decline in the population and continuing aging is a major concern for Korea’s economy, as working-age people will continue to drop and productivity will continue its downward trajectory.
