Not very far

According to a recent controversial study, people don't move around very much in their daily lives.

Tracking 100,000 cellphone users, the study found that most people spend the majority of their year traveling within a 20 mile radius, and that this pattern appears to persist even when those people traveled to a farther distance. 

As we think of our world's expansion because of film, planes, and the Internet, it's fascinating to consider that we may be no different than our ancestors, who were limited to horseback or foot. They didn't travel too far either, and when they got somewhere, they usually stayed put. 

On the good side of this, the more we push people to consider investing locally, the more we're going to see this pattern remain true for a larger population. On the not so good side, I'm sure some of us are wondering how ethical it is to be secretly "followed" through GPS tracking via your cell phone. And finally, it really does show you how people follow the cities where the jobs are. Places like downtown Bellevue are literally banking on this. For all the workers of Microsoft that will be transferred to downtown Bellevue, I believe some will be looking into housing options within 1 15-20 mile radius.
