Redfin Reports Americans Are Leaving Areas at Risk of Poor Air Quality, Mostly Because They're Expensive

Redfin's latest report reveals that U.S. counties with high air-quality risk lost 277,740 residents in 2025, a significant decrease from the 603,270 outflow seen in 2021. The analysis indicates that while environmental concerns are present, affordability remains the primary driver for migration, as people leave expensive coastal hubs for more affordable inland markets. A Redfin survey highlighted that 36% of homebuyers now consider high-end air filtration systems a top priority, reflecting growing consumer adaptation to poor air quality.
