Best In Colorado Real Estate™: Boulder

Boulder County’s inbound migration is now 79.5% concentrated in just three states — Colorado, California, and Texas — according to ALEX Intelligence’s new analysis of IRS migration data (https://alex-companies.com/data/2026-10-26-boulder-mig-state-top3). This isn’t just a demographic trend — it’s a structural force reshaping the local economy. The dominance of high-income, high-mobility populations from these states is accelerating inequality and entrenching a self-reinforcing market that resists diversification. What does this mean for long-term residents, affordability, and future development? How might this pattern shift if one of these top three states experiences a downturn in migration? The data is clear: Boulder is not becoming more diverse — it’s becoming more exclusive.
