American history is a story of immigration and diversity. As of June 2012, people of color constituted 36% of the workforce, and the Census has predicted that by 2050, there will be no racial or ethnic majority in the United States. Our nation’s diversity is often a point of pride among residents, as well as an appealing aspect of the United States for newcomers and visitors. In honor of Diversity Day, NerdWallet took a closer look at which cities contribute the most diversity to this melting pot.
