SEOUL (BLOOMBERG) - South Korea has once again shattered its own record for the world's lowest fertility rate as it faces the prospect of its population of 51 million people more than halving by the end of this century.
South Korean women were estimated, based on 2021 data, to have an average of just 0.81 children over their lifetimes, down from 0.84 a year earlier, the statistics office said Wednesday (Aug 24). The number of newborns declined last year to 260,600, which equates to about 0.5 per cent of the population.
South Korea is the world's fastest-aging nation among economies with per capita GDP of at least US$30,000 (S$41,900), according to United Nations global population projections and World Bank data. By 2100, its population will fall by 53 per cent to 24 million, up from a 43 per cent decline forecast in 2019.
The forecast is a sobering reminder of the demographic threat and associated economic challenges confronting Bank of Korea Governor Rhee Chang-yong and President Yoon Suk Yeol, who both took office earlier this year.
Rhee warned in April that South Korea's economy faces the risk of secular stagnation as the population ages and productivity slows. He said rising welfare spending would take away from the finance needed to boost economic growth, a key goal set out by Yoon in his inauguration pledges.
A shrinking workforce is a major factor in the decline of South Korea's potential growth rate. The working-age population peaked at 37.3 million in 2020 and is set to fall by almost half by 2070, according to Statistics Korea.
While seeking to slow the decline in the birth rate, South Korea is also enacting a series of measures to live with the new reality, enhancing living conditions for retirees and introducing more robots. Inviting more women, elderly people and foreigners into the workforce is another goal.
The number of women of child-bearing age fell 2 per cent to 11,620,000 last year, signalling the fertility rate is only likely to deteriorate further. A typical South Korean woman gave birth to her first child at age 32.6, up from 30.2 a decade earlier, according to the stats office. Her partner on average would be 35.1, compared with 33 a decade earlier.
By region, the capital Seoul showed the lowest fertility rate at 0.63, while Sejong, home to government headquarters, had the highest at 1.28, according to the stats office. The most populous province, Gyeonggi, recorded 0.85, closer to the average.
In the decades following the 1950-53 Korean War, the population at least doubled and in an effort to curb the baby boom in the early years of economic development, the government encouraged couples to have only one child.
That policy was scrapped around the turn of the century as births started to sharply fall, prompting the government to spend tens of billion of dollars each year to encourage more children, but with little success so far.
