America is becoming more racially and ethnically diverse, on its way to becoming majority non-white in 2045—but some parts of the country are changing more rapidly than the rest.
The counties seeing the greatest relative increase in racial and ethnic diversity are among the least diverse places in the country—particularly in the Midwest, Axios reports.
Using Census data, Axios calculated a diversity index for every county (or parish) in the United States going back to 2009. Each number represents the probability that two people chosen at random will be of a different race or ethnicity.
The country as a whole has a diversity score of 57.3, which means that there is about a 57 percent chance that two people chosen at random will be of a different background. Since 2009, the country’s diversity index has increased about 5 points. The most diverse counties tend to contain a big city or be near one. Least diverse counties tend to be more rural, have smaller populations, and are farther from the coasts.
According to the data, East Baton Rouge Parish is about as diverse as the rest of the U.S., with a score of 57, but it’s diversity score went up almost 5% from 2009 to 2017. The parishes surrounding Baton Rouge have significantly lower diversity scores, but showed greater increases in diversity over time, with Livingston Parish’s score increasing by nearly 25%.
