How quickly does a fertility rate of 0.7 shrink each generation?
Core argument: South Korea's fertility rate of 0.7 is the lowest of any nation in the world and may be the lowest in recorded history.
South Korea has a fertility rate of 0.7. This is the lowest rate of any nation in the world. It may be the lowest in recorded history. If that trajectory holds, each successive generation will be a third the size of its predecessor. Every hundred contemporary Koreans of childbearing age will produce, in total, about twelve grandchildren. The country is an outlier, but it may not be one for long. Middle-aged Koreans remember a time when children were plentiful. In 1970, a million Korean babies were born. An average baby-boomer classroom had seventy or eighty pupils, and schools were forced to divide their students into morning and afternoon shifts. It is as though these people were residents of a different country. In 2023, the number of births was just two hundred and thirty thousand.
