The populations of Colorado and California have both flatlined after decades of increases. Colorado growth this century was spectacular and has not yet hit zero but dropped to its lowest level since 1959 and was only 0.4% in the last 12 months, below the slow U.S. growth rate. There have been declines in some key metro cities like Boulder and Denver.
In 1965, I couldn’t wait to move to California, find a job in Hollywood and start college. Not today. Millennials and Gen Z are not flocking to the Golden State. California has seen a significant fall off after being the country’s growth leader for decades, primarily because people have stopped moving there.

After the 2000 Census, Colorado gained its eighth Congressional seat and California, for the first time in history, lost one. Both states in recent decades received high net in migration. It has stopped both internationally with the closed borders since 2024 and internally due to much lower U.S. inflow matched or exceeded by outflow, especially in California. If California growth doesn’t increase, it could lose up to 4 Congressional seats in 2030.
