The latest issue of the the Atlantic has an interesting set of statistics concerning the percentage of physicians that leave their own country to practice elsewhere. According to a study by the New England Journal of Medicine Ireland loses 41.2% of its graduates to the four countries of US, UK, Australia or Canada.
The actual figures are stated as 9,166 physicians practicing in Ireland, with 6,423 graduates from Ireland practicing in those 4 countries.
Roughly one fourth of all doctors in the United States, the UK, Australia, and Canada were born elsewhere; of those, anywhere from 40 percent (in Australia) to 75 percent (in the UK) come from low-income countries. (This dependence is largely confined to these four countries: in only three of the other twenty-six OECD nations do foreigners make up more than 10 percent of all physicians.) In absolute numbers, India supplies the most doctors to the four Anglophone countries cited, followed by the Philippines and Pakistan. However, the biggest proportional losses tend to be in Caribbean and sub-Saharan countries. And matters are likely to get worse before they get better, the study notes: mounting pressure in developed countries to increase the number of doctors will probably lead to further recruitment from overseas.
Here are the stats:
