# List of census-designated places in Colorado

The U.S. State of Colorado has 210 census-designated places. The United States Census Bureau defines certain unincorporated communities as census-designated places (CDPs) for enumeration in each decennial census. The Census Bureau defined 187 CDPs in Colorado for the 2010 Census and 210 CDPs for the 2020 Census.
At the 2020 United States Census, 714,417 of the 5,773,714 Colorado residents (12.37%) lived in one of these 210 census-designated places. Another 4,299,942 residents (74.47%) lived in one of the 272 municipalities of the state, while the remaining 759,355 residents (13.15%) lived in the many rural and mountainous regions of the state.
Colorado CDPs range in population from Highlands Ranch with a 2020 population of 103,444 to Fulford which lost both of its residents before the 2020 Census. Black Forest is the most extensive CDP with 101 square miles (261 km$^2$) of land area, while Blue Sky is the least extensive with 23 acres (0.093 km$^2$) of land area. Orchard Mesa was the most densely populated with a 2020 population density of 41,840 residents per square mile (16,155/km$^2$), while Cathedral was the lease densely populated of the populated CDPs with 0.70 resident per square mile (0.27/km$^2$).
Five Colorado CDPs extend into more than one county: Brook Forest, Coal Creek, Columbine, Strasburg, and Watkins.
The Town of Keystone incorporated on March 28, 2023.
