The United States has a longstanding reputation as being a melting pot (or salad bowl), with its diversity manifesting itself across many different demographics. However, some places across the country are notably more heterogeneous than others.
Stacker compiled a list of the most diverse counties in Montana using data from using data from the U.S. Census Bureau. Counties are ranked by the highest Simpson's diversity index score. Simpson's diversity index measures community diversity on a scale of 0 (least diverse) to 1 (most diverse), more on the calculation can be read here.
