Migration patterns...

Migration patterns...  Via friend, reader, and former colleague Simon M., this fascinating interactive map.  Click on any country, and all the other countries in the world become color-coded to show where immigrants to that country come from.  Click again on the same country, and it shows you where emigrants from that country go.  Just clicking around randomly showed up all sorts of patterns that were unexpected to me.  For example, Thailand is one of the top sources of immigrants to Iceland.  Brazilians emigrate in large numbers to Japan.  And over a million Russians emigrated to Germany in 2013!
