Race relations in America seem to be hitting a tipping point.

While we still haven’t dealt with racism as a society, the election of Donald Trump to the presidency has only flamed the tensions that have been mounting for years.

Part of the reason for that tension? The country as a whole continues to self segregate across race, income, and party lines. But it’s not all bad on the race relations front.

There are parts of Illinois where there’s a high level of diversity — where people of all walks of life come together. We decided to shine a light on those places today.

Using a standard measure of diversity, we ranked all 332 cities in Illinois from most to least diverse.

So what city is the most diverse in Illinois? According to the most Census data, Bolingbrook took the number one over all spot for diversity in Illinois.

Read on below to see how we crunched the numbers and how your town ranked. To see where Illinois ranked as a state, we have a ranking of the most diverse states in Ameria.

How we determined the most diverse cities in Illinois for 2019

We still believe in the accuracy of data — especially from the census. So that’s where we went to get the breakdown of race across Illinois.

That lead us to the Census’s most recently available data, the 2013-2017 American Community Survey data from the US Census.

Specifically, we looked at table B03002: HISPANIC OR LATINO ORIGIN BY RACE. Here are the category names as defined by the Census:

  • White alone*
  • Black or African American alone*
  • American Indian and Alaska Native alone*
  • Asian alone*
  • Native Hawaiian and Other Pacific Islander alone*
  • Some other race alone*
  • Two or more races*
  • Hispanic or Latino
* Not hispanic or latino

We limited our analysis to non-CDPs with a population greater than 5,000 people. That left us with 332 cities.

We then calculated the HHI for each city by finding the racial breakdown of a city in percent terms, squaring them, and then adding the squares together. This left us with scores ranging from 2,738 (Bolingbrook) to 9,593 (Paris).

Finally, we ranked each city based on the HHI with a lower score being more diverse than a high score. Bolingbrook took the distinction of being the most diverse, while Paris was the least diverse city.
