How We Determined The Largest Cities In Colorado
We've been ranking and dissecting cities in the Centennial State for over 4 years now -- making this actually the fourth time we've run the numbers. We always use the best data, the US Census. In this case, that means we are using the American Community Survey.
It what is probably the most simple analysis we run each year, we ranked every place in Colorado from biggest to smallest. The biggest city this year? That would be Denver.
The smallest? Aetna Estates, although there are places smaller than 1,000 people not listed here, so keep that in mind as we take a look at the top ten.
Now on to numbers 11-100 Biggest in Colorado
We hope that you find the big city, or really any city, that's right for you. Below is a list of the rest of the biggest cities along with every other place in Colorado.
Have fun snacking around in the Centennial State!
