Interestingly there was a discussion over Bill Gate's measuring teachers report with heated debate about the right graph to choose (scatterplots vs xxx) I like this and it is interesting information, but sorry, the "right" graphic to use here is the Mercator projection. I have to scroll down a long way to see which country people leave Azerbijan for (Russia). But the data is interesting. And its a helluva lot harder…

Why the Mercator projection specifically? It's a map projection for navigation purposes. What makes sense is for the right/left column to re-arrange itself by size once you click on a corresponding country.

Interestingly, both the UK and Russia are top destinations for people to both go to and leave. Also there seem to be almost as many people leaving Russia to go to the Ukraine as leaving Ukraine to go to Russia. Any one have any idea why this would be?

I have no idea if this is related, but I remember reading something a while back about how hard this type of data is to interpret.

A poignant example was given, describing how an entire city might switch countries, for example from Ukraine to Russia (and maybe back again?), and how that is a difficult situation to deal with.

Do the entire occupants of that city count as emigrants? What if they then decide to move back across the border? What happens if the city moves back a year later?

In any case, I don't know if there are issue like that here, but I would not be surprised if there were.

"but sorry, the "right" graphic to use here is the Mercator projection."

Maybe I'm just not understanding you, but this doesn't make sense to me. The site doesn't even show a map, what does the Mercator projection have to do with it?

It appears that in the UK people come for the posperity/jobs and people born in the UK leave because of the weather - or at least that's what the press here in the UK say.

another alternative (easier to program, but not the "natural" representation) would be to put the data in a circle and use the same location for both arrival and departure. i did something similar for package dependencies - the code is offline now, but you can see a screenshot at http://acooke.org/portfolio/practicl/

Adding in a table of the countries with the most emi/imigrants by proportion of the population would be useful. I thought Afghanistan had a high emigrant figure - 8% BUT New Zealand has 14% !

>10% of the Kiwi population went to their culturally-similar neighbour with a much better economy. Similar story with >15% of the Irish emigrating, mostly to less-economically-dire Britain (although there's a long established Irish exodus tradition), and for that matter the >1.2 million Brits off to Australia.

I expect most of these migrations won't be permanent, and these stats probably include a large proportion on 1 year working visas.

Yeah, and a key thing missing from these graphs is ease of movement. As far as I know, Australia is about the only country Kiwis can move to for work without requiring a visa, whereas the UK is getting stricter and stricter each year as it looks towards the EU rather than the Commonwealth.
