But today, we’re going to put opinions aside and look at the cold, hard facts — since 2010, which cities in Wyoming have grown the fastest.
After getting knee-deep in the Census’s American Community Survey using Saturday Night Science, we emerged with this set of cities in the Equality State that have people climbing over each other to get in.

Methodology: How We Measured The Fastest Growing Cities In the Equality State for 2026
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 2024)
We ranked all 16 Wyoming cities with a population over 6,000 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 Equality 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 2026. This report is our eleventh time ranking the fastest growing cities in Wyoming.
