Kurzgesagt did an episode on South Korea’s population problem, it was pretty bleak. https://youtu.be/Ufmu1WD2TSk
Yeah, because data extrapolations 75 years into the future are definitely reliable.
Just like all the predictions from 1950 on how life in 2025 would be.
Just the flying cars and household robots will still have to wait 🙁
This seems to imply a great healthcare system for the elderly with no funding from the young. Would life expectancy really continue to climb in such an economy? Generally infrastructure would crumble without investment I would think? This feels pretty idyllic, finding some form of stability. I would not be so confident that is achievable.
really cool work. love this data visualization, OP.
I gotta learn how to do it myself
Those nursing homes are gonna be lit in 2069
This provides no information on total population which is simple to show and seemingly important.
I knew it was one of the worst in the world, but the visualization is staggering.
Great color scale choice matching the Korean flag
South Korea is really bad for this.
I have a good friend who’s daughter is teaching over there (female). She would like to become a citizen and has been there for about 6 years now. But they do not want foreigners to boost the population.
They want Koreans to have more Koreans and make it very very difficult to emigrate there and get citizenship.
Basically, she is there for another year or two and then leave so a female professional that could have kids there, can’t become a citizen on her own, she has to marry to become one.
If she stays long term just working, she can’t retire there as the services wouldn’t be available to her as a non-citizen if she retired there.
Its just backward thinking in my mind.
That and the fact that the pollution is so bad its making everyone sterile.
What’s missing from these charts is the fact that S. Korea’s population is expected to be reduced by 50% by 2100.
