Anecdotal evidence suggests that increasing numbers of South Asian immigrants are coming to South Africa. Apparently, a significant proportion of the population of Indian townships [areas formerly set aside for South African "Indians"] is made up of recent immigrants from South Asia, although there are also stories about these immigrants setting up house in traditionally black areas (lacking apartheid-era hangups about race, they are said to assimilate rapidly).
The implications, particularly in fields like IT, should be obvious.
