Methodology
To find the fastest-growing cities in Colorado, we analyzed recent U.S. Census data. We eliminated towns with populations of less than 5,000 residents (as those can easily see misleading-high percentage increases with just a small number of new residents). We then calculated the population percentage increases for the remaining cities and ranked the cities by the highest percentage change.
