84% of the German population is ethnically German, so the commenter above was probably spectacularly unlucky. They are right though in that it is an aging population with only around 13% under 16.
87% of the overall population, yet only 13% of the child. That’s a stark difference.
But the comment reminds me of an observation in SE Asia - go to Singapore and very few kids and tons of senior citizens.
Then go to Vietnam and its most people in their 20’s and younger. It’s a difference you can’t help but notice.
And since Singapore is extremely selective about who they give citizenship too, they’re really struggling with the age pyramid. I believe the estimate is it will be 2 workers for every retired person by 2030.
