You are reading TOO much into it. It just means there's POTENTIAL demand from X to Y city. It's just searches and doesn't represent people who actually moved. This is merely one subset of the overall picture. There's more than just Redfin first of all. Second of all, you will have many people who aren't even interested in owning anytime soon and therefore aren't going to be looking on Redfin anyway.

The 18.7% one you showed is in and of itself for that area. An 18.7% for Denver is probably smaller than a 3% for NYC area. Did you know that Chicago is 100 miles closer to Denver than LA is? I talked with a coworker who actually grew up in Denver about this. She wasn't surprised that Chicago was #1 as she said going back many years there Chicago was always one of the big places to go for people from there when they wanted to get out of CO.
