Methodology: How We Measured The Fastest Growing Cities In the Treasure State for 2024
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 2022)
We ranked all 17 Montana 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 Treasure 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 2024. This report is our tenth time ranking the fastest growing cities in Montana.
Here’s a graph of the cities in Montana with the most significant percent increase in population:
