I did some maths today & was calculating whether South Africa's white population could all fit into Robben Island like many advocates of a white-free South Africa wish for & the answer is, they couldn't.
The white population of South Africa is currently at around 5 million & the area of Robben Island is 5 km squared (2 miles squared). This would make for an uncomfortable 1 million people per kilometre squared population density.
So how many white South Africans can live on Robben Island were it to be a whites only country? The most densely populated regions in the world, the Principality of Monaco & Macau, have a population density of around 20 000 people per square kilometre. For Robben Island, 20 000 people per square kilometre equates to 100 000 people on the whole island. Which is less than a fiftieth or 0.02% of the white population of South Africa. So they couldn't all be relocated there & a large majority of them would need to remain in the Western Cape (Khoi & San territory) if we were to decolonise our lands unless the #AmicableDeportation concept is implemented.
Trivia: If Robben Island were to become a sovereign state, they'd be bigger than Monaco & the Vatican City & about the same size as Gibraltar.
