Colorado, known for its stunning landscapes and diverse communities, boasts a rich tapestry of 273 active municipalities, comprising 198 towns, 73 cities, and two consolidated city and county governments. The state's capital, the City and County of Denver, holds the distinction of being the oldest municipality, dating back to December 3, 1859, when it was granted a charter as part of the extralegal Territory of Jefferson.

The newest addition to Colorado's municipal roster is the Town of Keystone, which was incorporated on February 8, 2024, adding to the state's vibrant community fabric. These municipalities vary widely in population and geographical features, from Denver with a bustling 2020 population of 715,522 residents to the secluded Town of Carbonate, which remains uninhabited year-round due to harsh weather conditions.

In terms of population density, the City of Glendale stands out with 8,117 residents per square mile, while the Town of Bonanza maintains a more tranquil pace with just 38 residents per square mile. Geographically, Colorado municipalities span from the expansive City of Colorado Springs, covering 195 square miles, to the compact Town of Sawpit, which spans a mere 19 acres.

As of the 2020 United States Census, the majority of Colorado's residents, approximately 74.47%, resided within one of these active municipalities, underscoring their significance as centers of community and governance. The remaining population resides in census-designated places or rural and mountainous areas, highlighting the diverse living environments across the state.

With each municipality contributing its unique charm and character to Colorado's landscape, from urban hubs to tranquil retreats, the state continues to attract residents and visitors alike with its blend of natural beauty and vibrant community life.
