The whole world seems to be getting older even Nigerias older population seems to be increasing. I do worry about how we are gonna take care of our elderly in the future. I hope birthrates level out or we find a way to take care of them without collapsing the economy.
Also it seems that our politics have slowly but surely been centering the old and imo have created many of the problems we see in the west today.
Just some of my thoughts when looking at this data
Don’t know too much on this, but I do know South Korea had a period, much like China, of worrying about overpopulation and they had a lot of policies in place to discourage births. That might be part of what’s behind that steep fall.
Why did you use Nigeria if we know that their fertility rate and population numbers are fabricated? Kenya also is a large high fertility country with much better data and track record.
(Kenya has a UN Age-Sex Accuracy Index of ~22 while Nigeria lies at ~60. That means Nigerias data is trash. You can also look at the history of their censuses to see why they got this extremely bad score)
Edit: sources
[Nigeria](https://www.researchgate.net/figure/The-United-Nations-Age-Sex-Accuracy-Index-for-2006-Nigeria-Census_tbl1_334442330) (2006 was their last census so we don’t have anything newer to work with)
[Kenya](https://www.knbs.or.ke/wp-content/uploads/2023/09/2009-Kenya-population-and-Housing-Census-Analytical-Report-on-Population-Dynamics.pdf) (search for age-sex Accuracy index or look for page 28)
This is pretty neat. You should mark when the projection (compared to actuals) begins. Make the legend and axis bigger and more readable. Consider another color than red because it implies danger
Every time I see predictions for the year 2100 I laugh.
Even just 10 years ago, predictions for today would have been hilariously wrong in multiple important ways (AI, Trump, Russia, …).
This is as credible as tea leaf reading.
