Which City has the biggest Diversity of all around races?

Good question, but not sure which one because each city is unique in it's own way. New York City (The Big Apple) has many diverse populations and shops as well as good schools with a diverse selection. Los Angeles (The City of Angels) has diverse culture as far as food and music and all the big shots are in Hollywood ranging from Usher to Carrie Underwood and Aerosmith to Boyz II Men. Chicago (The Windy City) has diversity in it's urban and suburban neighborhoods ranging from the ghetto to eazy street. and don't forget the eateries. So to answer the question each city has it's own unique diversity and each one should be looked at accordingly so I say that there all diverse in there own way.
