DENVER – Cities along the Front Range continue to grow at a solid clip, according to new population estimates from the federal government.

The U.S. Census Bureau this month released its July 2017 population estimates and the numbers show that Colorado’s population as a whole rose to 5,607,154 last year, which represents an increase of about 11.5 percent since the 2010 Census.

Looking at individual cities, Timnath has seen the biggest population increase since 2010. It had an estimated population of 3,295 as of July, an increase of 427 percent from its 2010 population of 625.

Like Timnath, some of Colorado’s smallest towns have seen the biggest increases in terms of percentage due to their relatively small populations, so for the sake of this list, we’re comparing cities with populations of 10,000 people or more.

With that in mind, here are the Colorado cities that have seen the biggest increases in population since the 2010 Census:
