Methodology: How we determined the whitest places in Idaho for 2025
To rank the whitest places in Idaho, we used Saturday Night Science to look at Census demographic data.
We had to look at the number of white people living in each city in Idaho on a per capita basis. In other words, the percentage of white people living in each city in Idaho.
We looked at table B03002: Hispanic OR LATINO ORIGIN BY RACE. Here are the category names as defined by the Census:
- Hispanic or Latino
- 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*
Our particular column of interest here was the number of people who identified as White alone.
We limited our analysis to town with a population greater than 5,000 people. That left us with 32 cities.
We then calculated the percentage of residents that are White. The percentages ranked from 89.3% to 45.8%.
Finally, we ranked each city based on the percentage of White population, with a higher score being more White than a lower score. Preston took the distinction of being the most White, while Rupert was the least White city.
We updated this article for 2025. This report represents our tenth time ranking the whitest cities in Idaho.
