How many ethnicities are there in the world?
More than 5,000.
There are more than 5,000 ethnic groups in the world. This is according to a 1998 report entitled ‘ËœBy the Numbers: Ethnic Groups in the World’â„¢ published in the Scientific American in September 1998. Estimates vary, and the classification of ethnic groups remains vague and debatable. Since there are 6,909 living languages worldwide according to the 2009 Ethnologue, it can be safe to assume that each language is spoken by at least one ethnic group; therefore there would be at least 6,909 ethnic groups throughout the world.
