The Other Side
I think that your figure is vastly overestimated.
According to "Polish Statistical Yearbook of 1938" Africa's total population in 1935 was 148.2 million.
And according to "Polish Statistical Yearbook of 1939" Africa's population in 1936 was 151.7 million.
Well, if you'd like, you can read the researchers' paper and let them explain their process. Based on their authority and prestige, I'm somewhat inclined to believe them, but I'm not in a position to claim certainty.
