1) Oakland (Diversity Index: 65%)
With a Diversity Index of 65 percent, the port city of California is the most ethnically diverse city in America. This is a little surprising because the population of Oakland is much less than those of some other American cities. Population of this city is 413,775. The city is a thriving hub for black culture.
The Diversity Index was ranked by measuring how much other races were present in the total population of the city when compared to the majority race.
