South Korea has broken its own record for the world's lowest fertility rate, as the country struggles to reverse its years-long trend of declining births. The country's fertility rate, which indicates the average number of children a woman will have in her lifetime, sunk to 0.81 in 2021 -- 0.03% lower than the previous year. The 2021 fertility rate was 1.6 in the United States and 1.3 in Japan, which also saw its lowest rate on record last year. As of last November, 16.8% of South Koreans were over 65 years old, while just 11.8% were aged 14 or under. About South Korea Capital: Seoul Currency: South Korean won President: Yoon Suk- yeol
