Facebook does not ask for your race. But a recent study used the US Census data to predict the race of users from their surnames. For instance, a person with a surname Washington was 89% likely to be black.
Based on this study, here’s the race based split up of Facebook’s 100 million American users
White : 74%
Black : 11%
Latino : 9%
Asian : 6%
1 thing… Please change “Blacks” to “Black”!
Thanks for pointing out, Michael..Have made the correction.
