Methodology: How We Determined The Cities In Iowa With The Largest Hispanic Population For 2025
We used Saturday Night Science to compare data on race from the US Census for every city in Iowa.
Iowa’s most recently available data comes from the 2019-2023 American Community Survey.
Specifically, 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 Hispanic or Latino.
We limited our analysis to places in Iowa with a population greater than 5,000 people. That left us with 76 cities.
We then calculated the percentage of Hispanic or Latino residents in each Iowa city. The percentages ranked from 48.7% to 0.4%.
Finally, we ranked each city based on the percentage of the Hispanic or Latino population, with a higher score being more Hispanic or Latino than a lower score. Denison was the most Hispanic or Latino, while Maquoketa was the least Hispanic or Latino city.
We updated this article for 2025. This article represents our tenth time ranking the cities in Iowa with the largest Hispanic/Latino population.
