Round the world, nations are trying on the prospect of shrinking, growing old populations – however none extra so than South Korea.
During the last 60 years, South Korea has undergone essentially the most fast fertility decline in recorded human historical past. In 1960, the nation’s whole fertility price – the variety of youngsters, on common, {that a} lady has throughout her reproductive years – stood at slightly below six youngsters per lady. In 2022, that determine was 0.78. South Korea is the one nation on the planet to register a fertility price of lower than one little one per lady, though others – Ukraine, China and Spain – are shut.
As a demographer who over the previous 4 a long time has performed in depth analysis on Asian populations, I do know that this extended and steep decline can have big impacts on South Korea. It could decelerate financial development, contributing to a shift that can see the nation find yourself much less wealthy and with a smaller inhabitants.
Older, poorer, extra dependent
International locations want a complete fertility price of two.1 youngsters per lady to switch their inhabitants, when the consequences of immigration and emigration aren’t thought-about. And South Korea’s fertility price has been constantly under that quantity since 1984, when it dropped to 1.93, from 2.17 the 12 months earlier than.
What makes the South Korean fertility price decline extra astonishing is the comparatively brief interval wherein it has occurred.
Again in 1800, the U.S. whole fertility price was properly over 6.0. However it took the U.S. round 170 years to constantly drop under the substitute stage. Furthermore, within the little over 60 years wherein South Korea’s fertility price fell from 6.0 to 0.8, the U.S. noticed a extra gradual decline from 3.0 to 1.7.
Fertility decline can have a constructive impact in sure circumstances, through one thing demographers seek advice from as “the demographic dividend.” This dividend refers to accelerated will increase in a rustic’s financial system that observe a decline in delivery charges and subsequent modifications in its age composition that lead to extra working-age folks and fewer dependent younger youngsters and aged folks.
And that’s what occurred in South Korea – a decline in fertility helped convert South Korea from a really poor nation to a really wealthy one.
Behind the financial miracle
South Korea’s fertility decline started within the early Nineteen Sixties when the federal government adopted an financial planning program and a inhabitants and household planning program.
By that point, South Korea was languishing, having seen its financial system and society destroyed by the Korean Warfare of 1950 to 1953. Certainly by the late-Nineteen Fifties, South Korea was one of many poorest international locations on the planet. In 1961, its annual per capita revenue was solely about US$82.
However dramatic will increase in financial development started in 1962, when the South Korean authorities launched a five-year financial improvement plan.
Crucially, the federal government additionally launched a inhabitants planning program in a bid to deliver down the nation’s fertility price. This included a aim of getting 45% of married {couples} to make use of contraception – till then, only a few Koreans used contraception.
This additional contributed to the fertility discount, as many {couples} realized that having fewer youngsters would usually result in enhancements in household dwelling requirements.
Each the financial and household planning packages have been instrumental in transferring South Korea from one with a excessive fertility price to at least one with a low fertility price.
Because of this, the nation’s dependent inhabitants – the younger and the aged – grew smaller in relation to its working-age inhabitants.
The demographic change kick-started financial development that continued properly into the mid-Nineteen Nineties. Will increase in productiveness, mixed with an rising labor power and a gradual discount of unemployment, produced common annual development charges in gross home product of between 6% and 10% for a few years.
South Korea right this moment is one of many richest international locations
on the planet with a per capita revenue of $35,000.
Shedding folks yearly
A lot of this transformation of South Korea from a poor nation to a wealthy nation has been because of the demographic dividend realized in the course of the nation’s fertility decline. However the demographic dividend solely works within the brief time period. Lengthy-term fertility declines are sometimes disastrous for a nation’s financial system.
With an especially low fertility price of 0.78, South Korea is dropping inhabitants every year and experiencing extra deaths than births. The once-vibrant nation is on the way in which to changing into a rustic with a lot of aged folks and fewer employees.
The Korean Statistical Workplace reported not too long ago that the nation misplaced inhabitants prior to now three years: It was down by 32,611 folks in 2020, 57,118 in 2021 and 123,800 in 2022.
If this development continues, and if the nation doesn’t welcome thousands and thousands of immigrants, South Korea’s current inhabitants of 51 million will drop to underneath 38 million within the subsequent 4 or 5 a long time.
And a rising proportion of the society might be over the age of 65.
South Korea’s inhabitants aged 65 and over comprised underneath 7% of the inhabitants in 2000. At this time, almost 17% of South Koreans are older folks.
The older folks inhabitants is projected to be 20% of the nation by 2025 and will attain an unprecedented and astoundingly excessive 46% in 2067. South Korea’s working-age inhabitants will then be smaller in dimension than its inhabitants of individuals over the age of 65.
In a bid to avert a demographic nightmare, the South Korean authorities is offering monetary incentives for {couples} to have youngsters and is boosting the month-to-month allowance already in place for folks. President Yoon Suk Yeol has additionally established a brand new authorities group to determine insurance policies to extend the delivery price.
However thus far, packages to extend the low fertility price have had little impact. Since 2006, the South Korean authorities has already spent over $200 billion in packages to extend the delivery price, with just about no influence.
Opening the trapdoor
The South Korean fertility price has not elevated prior to now 16 years. Slightly, it has continued to lower. This is because of what demographers seek advice from because the “low-fertility lure.” The precept, set forth by demographers within the early 2000s, states that when a rustic’s fertility price drops under 1.5 or 1.4, it’s tough – if not unimaginable – to extend it considerably.
South Korea, together with many different international locations – together with France, Australia and Russia – have developed insurance policies to encourage fertility price will increase, however with little to no success.
The one possible way for South Korea to show this round could be to rely closely on immigration.
Migrants are sometimes younger and productive and normally have extra youngsters than the native-born inhabitants. However South Korea has a very restrictive immigration coverage with no path for immigrants to develop into residents or everlasting residents until they marry South Koreans.
Certainly, the foreign-born inhabitants in 2022 was simply over 1.6 million, which is round 3.1% of the inhabitants. In distinction, the U.S. has at all times relied on immigration to bolster its working inhabitants, with foreign-born residents now comprising over 14% of the inhabitants.
For immigration to offset South Korea’s declining fertility price, the variety of international employees would possible have to rise nearly tenfold.
With out that, South Korea’s demographic future can have the nation persevering with to lose inhabitants yearly and changing into one of many oldest – if not the oldest – nation on the planet.
