That’s an entirely different thing than “per unit of time”. It’s a valid question, turns out there isn’t an answer, but some very basic searching linked me to the original map as released: http://cf.datawrapper.de/dduui/2/
To your edit, sure, there are diaspora maps for timeframes. Those are called immigration/emigration maps, because the acts of which grow or shrink a diaspora.
To be fair, I originally did say per what and when. So the when has always been an unanswered question. I’ve not changed my original question at all, because the original image doesn’t answer them
