I was quite interested in reading a recent article on the Moneyweb website, advising that South Africa had gained 400,000 white people since 2009.  I am not sure that one can draw the exact same conclusion that they have, that that growth is simply because of white expats returning to South Africa, but no doubt that is part of the story.  They seem to have discounted birth and population growth as a result that way.  The article essentially points out that the white population of South Africa was 5,9 million in 1973 and by 2009 was down to 3,9 million with the considerable number of people who immigrated.  They say since then the white population is now back to 4,3 million.  That is still of course 27% of the white population who have left South Africa, or died at a higher rate than being born, but it is good news that people are returning.  The article quotes an employment agency saying that there is a lot of demand for South Africans returning from overseas countries who have degrees and that they have also discovered, since the crisis in 2008, that there overseas jobs were not as secure as they had thought beforehand.  They obviously bring a lot of experience back with them and apparently they have been hired by a number of medium-sized firms doing business throughout Africa, particularly in the construction and engineering sectors.  The article estimates that some 2 million South Africans still live overseas.
