Methodology: How we determined the most diverse cities in Idaho for 2024
We still believe in the accuracy of data — especially from the Census — and Saturday Night Science. So that’s where we went to get the race breakdown across Idaho.
That leads us to the Census’s most recently available data, the 2018-2022 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
We limited our analysis to non-CDPs with a population greater than 5,000 people. That left us with 34 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 4,597 (Jerome) to 8,611 (Hayden).
Finally, we ranked each city based on the HHI, with a lower score being more diverse than a high score. Jerome took the distinction of being the most diverse, while Hayden was the least diverse city.
We updated this article for 2024. This report is our tenth time ranking the most diverse places in Idaho.
