Does that actually work that way? AFAIK the US freedom of movement is mostly resulting in greater and greater concentration... the only non-urban areas that are getting more and more popular are general "nice" (i.e. geographically advantageous) areas, like Florida and ski resorts.
I'm not sure I would call Florida geographically advantaged although a lot of people actually like it. (My understanding is taxes also make it attractive to retirees and second home owners.) Lot of growth in the desert Southwest (Arizona, Nevada) and Texas. It's mostly the Midwest that is conspicuously lacking.
The last few years there has been a significant increase in people moving from California to Texas. Texas now has the fastest state population growth rate.
Makes sense - I was in Wimberly about 4 years ago and it was so peaceful and quaint - it was a retirement town. Went over there again about 5 months ago and the downtown was bursting at the seams with cars. Same time of year - you can no longer walk across the street without looking - it's a danger zone now. Filled with hipsters and their wives and 2.2 kids.
There was an article on HN a few weeks ago about people moving to Boise to get away from the high cost of living in Silicon Valley. Is it a hellhole as in crime ridden or more because there's nothing there?
