Colorado’s population growth has slowed significantly, falling short of earlier projections.
The state, currently at 5.8 million residents, was expected to reach this milestone five years earlier and now isn’t anticipated to hit 6 million until 2026, well past the initial estimate of 2020.
Annual growth rates have dropped dramatically, from an average of 75,000 new residents per year between 2010 and 2020 to just 30,000 annually since 2020.
A key factor in this slowdown is Colorado’s low fertility rate—among the lowest in the nation—which reflects a broader national decline.
