Is being in an area that’s growing quickly a good thing or a bad thing?

Depends on who you ask. Some want bigger, more exciting cities like Denver and Colorado Springs, while others want peace and quiet like in Lochbuie and Manitou Springs, thank you very much.

But today we’re going to put opinions aside and just look at the cold hard facts — over the past five years, which cities in Colorado have the grown the fastest.

After getting knee deep in the Census’s American Community Survey, we emerged with this set of cities in the Centennial State that have people climbing over each other to get in:

  1. John
  2. Monument
  3. Frederick
  4. Lone Tree
  5. Firestone
  6. Erie
  7. Lochbuie
  8. Commerce City
  9. Wellington
  10. Castle Rock

If you happen to be a resident of one of these communities, you’re probably not too surprised to find it on our list.

If you’re not–and you’re wondering why these places are kind of a big deal–keep reading. We’ll tell you what makes each of these 10 places in Colorado are growing like weeds–but first, a bit about our methodology.

How We Measured The Fastest Growing Cities In Centennial State

To figure out which cities are growing the most, we simply had to look at the growth rates for cities over the last five years, according to the American Community Survey put out by the census every year. Specifically:

  • Population in 2014
  • Population in 2010
  • Growth rate from 2010 to 2014 (The latest available data)

We ranked all 78 Colorado 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 Centennial State.

And for those of you who are a little rusty with their statistics, you can calculate the growth rate by the following formula:

[Population 2014 – Population 2010] / [Population 2010]
