 Of the top 15, 10 out of 15 are in Florida and Texas. Texas, having eight of the fastest growing cities, five of them, more than half, are right around the metropolitan area of Dallas. Then you have two around the metropolitan area of Austin and one around Houston. But in Florida, it's interesting, the heart of Florida is growing the most because the two cities in Florida, Haines, Florida, and Leesburg, Florida, are both within a stone's throw of Orlando.
