South Africa> Spain?

Think of it as Brit and Dutch > Spain.

Yeah, obviously these stats aren't representative of the population if less than 10% are Brit or Dutch

Yeah but then its useless to generalize to the population

It's in Current Biology. Cell is the domain. It's like when you see http://nature.com , but it's in some other journal on same domain. Publisher trick.
