7 billion +- 10% people live on earth. Approximately the half lives in China, India or South-East-Asia.
I'd say 1 billion +- 50% people live in Africa. There exist 60 +- 50% countries.
I assume that south of the Sahara the population of a country somehow correlates with its size.
D: South Africa
Furthermore South Africa is part of the G20 and the BRICS countries.
For the record: Imrich Lichtenfeld / Imi Sde-Or lived in Bratislava not Wien before he fled to Palestine / Israel.
