South Korea’s bachelor time bomb is about to really go off. Following a historic 30-year-long imbalance in the male-to-female sex ratio at birth, young men far outnumber young women in the country. As a result, some 700,000 to 800,000 “extra” South Korean boys born since the mid-1980s may not be able to find South Korean girls to marry.
As a demographer who over the past four decades has conducted extensive research on East Asian populations, I know that this increased number of South Korean boys will have huge impacts throughout South Korean society. Coincidentally, similar trends are playing out in China, Taiwan and India.
