International mobility of Nobel prize winners in science, 1994-2017

The pie chart shows the number of Nobel prizes awarded between 1994 and 2017 by the country in which the universities of the prize-winning researchers are located. Out of 179 prizes, almost half were obtained in the United States; the United Kingdom and Japan, which come second, won far fewer. The first ten are therefore all countries in the Northern hemisphere. The arrows show the thirty or so researchers who migrated between starting their research and winning the Nobel Prize; most of them were attracted to the United States, which comes far ahead of the United Kingdom and Australia.
