The times when fertility rises in these countries seem to be mainly when GDP per capita is rising quickly. (Slight rightward lean to the up-surges). Not every time, but the boxes seem more inclined to drift to the right only when they are rising if at all.
Not every upward surge drifts rightward (Japan), but the overall leftward drift of fertility seems more noticeable when GDP/capita isn't rising very quickly, or is falling. (Norway, USA)
Would a semilog chart show things better? (log GDP per capita.)

Good question. Log GDP animation will be in today's QTRS.
I wish I had the coding chops to display panel data like this. A famous example is Hans Rosling: https://www.youtube.com/watch?v=hVimVzgtD6w&t=176s
It's awesome to hear a data scientist say "Start the world!"
Hans Rosling was brilliant. Animated data by time is a really powerful tool to understand data.
