Just having dragged the scroller for the embedded sample for Halifax, N.S. a simple, idle question occurs to me: I presume that this is all not just regression to the mean? Is there something deeper than that demonstrated here?
I would like to see what it is like for a small sliding scale. Give me the same data with the ability to slide it over a 10 year or 10 month period. Do the smaller population areas flip back and forth between "mobile" and "immobile"?
