업데이트 된 한국의 출산율: 0.78... 국가소멸이야기가 나오는데... 그래서 한 명 한 명 아기들이 너무나 소중!
Fertility rate (fertility rate of 2.1 children per woman ensures a broadly stable population): All countries who has less than 2.1 ratio should open their borders for immigration to stabilize the population growth.
BTW, the updated fertility rate in South Korea is 0.78. Dangerous.
