Nigeria is another African nation that has suffered due to a massive brain drain. With much of Nigeria still essentially a developing nation with unreliable power and few resources, higher level science, engineering and medical professionals often find little to motivate them into staying, especially with job offers from the U.S. and European nations exerting a powerful pull. Since Nigeria’s brutal civil war in late 60s, the country has bounced between military governments and dictatorships, pushing out between 11 and 17 million people. Today, over 2.5 million Nigerians live in the U.S. alone, and of these about 40,000 are doctors and over 20,000 are academics. That’s a heavy loss for a nation that so desperately needs qualified professionals to rebuild and improve its own resources.
