10 Most, Least Ethnically Diverse Cities in America

In 25 years, the United States will be the most "colorful" it's ever been, as WalletHub puts it. That's because by 2045, it's estimated there will be no single ethnic group that can claim the most people in the nation. To find out which US cities are ahead of the pack as the most ethnically diverse, the site looked at more than 500 of them across three key metrics: ethnoracial diversity, languages spoken, and birthplace diversity (whether they were born abroad, in US territories, or in various sections of the US). Maryland claimed four cities in the top 10. Read on to see how cities across the US ranked:

1. Jersey City, NJ (No. 1 in the "Linguistic Diversity" category)
2. Gaithersburg, Md.
3. Germantown, Md.
