Colorado State Population

A population nearing 6 million.

Colorado's population stands at approximately 5.8 million, reflecting a history of dynamic growth since its territorial days. The initial surge in the mid-19th century was fueled by the gold rush, transforming a sparsely populated frontier into a burgeoning state, followed by steady expansion through the 20th century, driven by agriculture, mining diversification, and the emergence of military and aerospace industries. More recently, the state has experienced significant, sustained growth, especially in the 21st century, attracting new residents primarily through its robust technology, aerospace, and outdoor recreation sectors, coupled with its desirable lifestyle and natural amenities. This influx has largely concentrated in the Front Range Urban Corridor, leading to increased urbanization, a more diverse demographic profile, and ongoing challenges related to infrastructure, housing affordability, and resource management.
