America’s Melting Pot Cities

Methodology

To determine America’s melting pot cities, 24/7 Wall St. ranked metro areas based on the likelihood that two residents picked at random would be from two different world regions: the United States, Europe, Asia, Africa, Oceania, Latin America, and other parts of North America. The measure refers to the birthplace of the current residents. The index is based on the share of residents of a specific national origin with 5-year data from the U.S. Census Bureau’s 2017 American Community Survey and is the sum total of the individual probabilities that two residents will not share a national origin. The same method is used in the USA Today Diversity Index. Supplemental data on race, ancestry, income, poverty, and population also came from the Census Bureau. Data on unemployment came from the Bureau of Labor Statistics and is seasonally adjusted for June 2019. Data on regional price parity, or cost of living, came from the Bureau of Economic Analysis and is for 2017.
