There is the vast amount of documentation on why people move to the suburbs. We know almost nothing, however, about why people do not move to the suburbs or, if they have lived in suburbs and now live in the city, why they changed their minds.

William H. Whyte says:
One thing is clear. The cities have a magnificent opportunity. There are a definite signs of a small but significant move back from suburbia. There is also evidence that many people who will be moving to suburbia would prefer to stay in the city - and it would not take too much more in amenities and space to make them stay.
