However, flight of human capital in South Africa should not be attributed solely to regional factors. For example, the demand for skilled labourers in the UK, US, Canada, New Zealand, and Australia has led to active recruitment programs by those countries in South Africa. These countries accounted for 75% (by volume) of recent skilled emigration with the UK receiving approximately half of annual skilled South African emigration from 1990 to 1996. It has been suggested that the role of domestic socio-political variables may be negligible. The health sector has been hit particularly hard.
