Moving Trends for 2025

1990s look like the biggest spike in Colorado population growth.

Colorado's population has grown significantly from roughly 2.2 million in 1970 to over 6 million by mid-2025. Driven by high net migration, the state more than doubled in size over these five decades, with rapid growth in the 1990s and 2010s. Growth recently slowed to its lowest rate since the 1980s, driven by natural increase rather than migration.
