"Guyana loses a greater proportion of its high-skilled workforce to OECD countries than any other non-member nation, the OECD reports. It finds that 83% of the country's graduates now live in an OECD country. Size is the best predictor of emigration. Smaller countries, especially African and island nations, send a higher proportion of their graduates to the OECD. Big ones, such as Bangladesh, keep most of theirs."
