South Koreans Face Extinction by 2750
Don't be alarmed, that is a long way off by a few hundred years. However, a study conducted in 2014 found that "South Koreans could 'face natural extinction by 2750 if the birthrate were maintained at 1.19 children per woman — assuming no reunification with North Korea or significant inflow of migrants."
The research conducted by Brookings Institute and commissioned by the National Assembly in Seoul, also found that South Korea's current population of 50.2 million could fall to 20 million by the end of the century.
According to that simulation, the second-largest city, Busan is predicted to "go extinct" by 2413, whereas Seoul has a few more decades (predicted extincition is 2505).
There is still hope if the birthrate were to increase, or if a miraculous reunification with North Korea could happen...
Anything is possible, right?
