Is being in an area of Iowa that’s growing quickly a good thing or a bad thing?
Depends on who you ask.
Some want bigger, more exciting cities like Des Moines and Cedar Rapids, while others want peace and quiet like in Iowa Falls and Sergeant Bluff, thank you very much.

After getting knee-deep in the Census’s American Community Survey using Saturday Night Science, we emerged with this set of cities in the Hawkeye State that have people climbing over each other to get in.

Methodology: How We Measured The Fastest Growing Cities In the Hawkeye State for 2025
To figure out which cities are growing the most, we used Saturday Night Science to look at the growth rates for cities since the beginning of the decade, according to the American Community Survey put out by the census every year. Specifically:
- Current Population
- Population in 2010
- Growth rate from 2010 to Current (The latest available data which came out in Dec 2023)
We ranked all 84 Iowa cities with a population over 5,000 people from highest growth rate to lowest.
The city with the highest growth rate during this time was crowned the fastest-growing city in the Hawkeye State.
And for those of you who are a little rusty with their statistics, you can calculate the growth rate by the following formula:
[Current Population – Population 2010] / [Population 2010]
The data has been updated for 2025. This report is our tenth time ranking the fastest growing cities in Iowa.
Here’s a graph of the cities in Iowa with the most significant percent increase in population:
