The Global Brain Trade
The Global Brain Trade - RF CafeThe September 2012 edition of IEEE's Spectrum magazine has an interesting chart on the last page that shows the percentage of researchers that immigrate/emigrate to/from 16 different countries versus how many emigrate from the them. The chart bars represent percentages, not absolute numbers. Switzerland has the highest number of researchers immigrating to it (~60%) while about 35% emigrate from it. We don't know whether any of those immigrants stayed a while and then joined the emigrants ranks. India has the greatest number of researcher emigrants leaving (~40%) while immigrants relocating to India are almost immeasurable. China is not included because access to researchers there was too restricted (gotta love those Communist regimes).
