LIke a lot of surveys, this one has some real methodological issues. My family moved every five years or so, and each time it was to a differnt kind of environment. How to answer that?

Seems like the original survey was designed to prove a point...and it doesn´t. But then, I design surveys as part of my job, and I´ve never designed one that didn´t leave at least one question unanswered...because we didn´t see it coming!
