South Korea's birth population has rebounded for two consecutive years, successfully hitting the bottom as a preliminary version. The overall birth rate in South Korea had been declining, reaching a low of 0.72, then rebounding to 0.75 two years ago and 0.8 last year. This means that each woman of childbearing age on average gives birth to 0.8 children in her lifetime. Although this figure is still very low, it at least indicates that the decline is not endless. China's total fertility rate is around 1.09, which has been decreasing year by year and may drop below 1 in the future. However, if South Korea can bounce back from the abyss, it is good news for us. The internationally recognized normal population replacement level is 2.1, and anything below 1.3 is considered ultra-low fertility.
