The current census figures support the fact that far more whites are remaining in South Africa than in neighboring African countries, and they CAN just pick up and leave - other African countries are courting them (and white Zimbabweans) to help stimulate the economies of those countries.
Have some white South Africans left? Absolutely, yet proportionally many more remain than in Zimbabwe - because the South African government has always pursued a different policy than Mugabe. Some whites today still move to South Africa.
As far as any stats, coming out of RSA are concerned, taking them as gospel is akin to believing that under Obama, the American economy was a roaring success for everyone. LOL
