South Korea Births Jump 6.8%, Lifting Fertility to 0.80
South Korea’s births rose 6.8% in 2025 to 254,500—the largest yearly increase in 18 years—lifting the total fertility rate to 0.80. The rebound, helped by the early- to mid-1990s cohort entering peak childbearing age (the so-called second echo-boom) and continued government incentives for marriage and childbirth, follows two years of gains and comes as firstborns rose 8.6% and the average maternal age reached 33.8. While the trend signals a demographic upswing, the fertility rate remains the OECD’s lowest.
