Open immigration is a very good thing for ageing countries.

Interesting stuff. Why is Nigeria so nicely exponential?

Also, I wish that the colour saturation varied as a function of temporal distance from the present day, i.e., 2015 (2013 rounded) is the most saturated, 2010 and 2020 are the second most saturated, and so forth. Right now, saturation increases as a function of time, and that means that there is no obvious point that demarcates past, observed data and future, predicted data.

I'm glad I don't live in any of these countries. I get to live past 79.

That's interesting that in Japan's chart you can see both the Baby Boom and the Echo Boom (Boomers' kids) really clearly, but you can't see the Echo Boom in the US chart except as the teeniest waver. I suppose that's primarily US immigration evening out the Baby Boom somewhat?

No cannibalism crash as we run out of potash and topsoil?

It's because Nigerian women average 6 or 7 kids, and most of them live to adulthood. That's average! It's a disaster in the making. The averaging of 6-7 kids per woman, I mean, not the most of them living to adulthood part. You want virtually all kids to live to adulthood but only an average of 2 or so per woman. Or slightly less if you want to bring down your population gracefully.

Indeed. I feel like capping the data at 79, while perhaps necessary based on the data being used, seriously undersells the number of ageing boomers developed countries will be dealing with in 20 years.

Undulating wave of boomers.

GIFs are a useful and fun format for a lot of things. Hilarious RuPaul's Drag Race moments. Bunnies falling over. Graphs about ageing population, though, not so much.

Like most ways of presenting information, it has advantages and disadvantages. It's much easier to perceive the shift in Japan's age breakdown seeing the graph in motion this way. But I often wish GIFs came with a pause button so I could see individual frames for longer.
