The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid. This is based on a racial classification made by Carleton S. Coon in 1962. There is no universally accepted classification for “race”, however, and its use has been under fire over the last few decades. The United Nations, in a 1950 statement, opted to “drop the term ‘race’ altogether and speak of “ethnic groups”. In this case, there are more than 5,000 ethnic groups in the world, according to a 1998 study published in the Scientific American.
So should we go with 4 or 5,000?
