That sounds incredibly unlikely to me. Or, I suppose it could make sense, but only under a couple of circumstances:

1. Each year’s crop of UT students constitutes a large fraction of Austin transplants. But that doesn’t seem possible, as I can’t imagine that’s more than 20k a year.

2. Most transplants are from Texas, but every other Texas metro is experiencing similar intra-state migration, and so every big city in Texas is hollowing out the state’s hinterlands.
