Until the abolition of slavery at the end of the 19th century, over 80 percent of Brazil population was black. However, starting at the beginning of the 20th century the Brazilian government started a whitening policy until the middle of the 20th century by offering special settlement incentives to Europeans, Japanese and other non-Africans in order to dilute the African dominance.
Today, out of 191 million Brazilians 48% are white people. Black people are now less than 8%. 43% are considered mixed, 1% Yellow, and the original Indians population is now only 0.4% (less than half a million).
The whitening policy In Brazil succeeded just over 60 years period.
When I’m telling my fellow africans, don’t take your current demographic position in Africa as something eternal and unchangeable, they don’t believe me.
Europeans are not making enough baby anymore to conquer demographically a whole continent, but Chinese and Indians could team up with them like in the case of Brazil and easily change the demographic chart of any african country in less than half a century.
