Population of Colorado

Analysis# Colorado Population Analysis Colorado's 2024 population of 5,959,316 reflects steady 20th-century growth, with an 18.49% increase over the past decade positioning it as the 20th most populous state. The 1910s marked Colorado's most dramatic expansion, indicating that early 20th-century economic drivers—likely mining and early industrialization—outpaced subsequent decades' growth rates. The past decade's 18.49% growth rate suggests contemporary factors like migration and economic diversification have restored Colorado to mid-range growth rankings despite being well-established nationally.
