There are currently 64 counties in the U.S. State of Colorado but before Colorado became a U.S. state in 1876, it had only 26 counties. The number rose to 40 in 1885 after the creation of Archuleta County and eventually to 64 counties in 2001 when Broomfield was consolidated as a city and county.
These Colorado counties are important units of government in the state because there’re no townships or other minor civil divisions.
Out of these 64 counties, two (Broomfield and Denver) have consolidated city and county governments. Each county in Colorado has its own character and sense of identity.
Here is a list of all the counties in Colorado, their FIPS code, year formed, and population.
