Brain drain Definition
A brain drain or human capital flight is an emigration of trained and talented individuals for other nations or jurisdictions, due to conflict or lack of opportunity or health hazards where they are living. It parallels the term "capital flight" which refers to financial capital which is no longer invested in the country where its owner lives and earned it. Investment in higher education is lost when the trained individual leaves, usually not to return. Also whatever social capital the individual has been a part of is reduced by their departure. Spokesmen for the Royal Society of London first coined the expression “brain drain” to describe the outflow of scientists and technologists to the United States and Canada in the early 1950s.
