Centennial, CO
What Centennial is actually like
Centennial was incorporated on February 7, 2001, formed from unincorporated Arapahoe County areas including the former census-designated places of Castlewood and Southglenn, following a citizen vote on September 12, 2000 that passed with 77% approval; at the time, it was reportedly the largest incorporation in U.S. history, with a population already exceeding 100,000. The city's name references Colorado's 1876 statehood, granted in the U.S. centennial year -- the source of Colorado's "Centennial State" nickname.
Centennial is Colorado's 11th most-populous city (108,418 residents, 2020 Census) and is entirely suburban in character, spread across 29.87 square miles with major corporate employers including Comcast, UnitedHealth Group, and Arrow Electronics, headquartered there and Colorado's largest company by revenue. It hosts the second-largest IKEA store in the U.S. (opened July 27, 2011) and the international headquarters of Gamma Phi Beta sorority. The Denver Broncos' headquarters and training facility, in nearby Dove Valley, relocated there in 1990/2003.
