Where Are People Moving Too?

Within the U.S. and Canada, one view of the answer is in the map at right, which shows as blue those states/provinces with more people moving to them, orange with more people moving from them, and red for states with about the same amount of people moving too or from them.

Mind you, this view is a bit biased: it measures moves by Atlas Van Lines, which means it's looking at a slice of relatively well-off movers (a great many people cannot afford to pay the likes of Atlas for their services).  Another thing to watch: some of the absolute numbers are very small.  For example, 3 people moved out of Newfoundland, and 9 people moved in.  With a sample that small, I don't think we learned very much about Newfoundland!

But even with all the caveats, there are some surprises on here (for me, at least).  Why are people leaving Wyoming?  Why are people moving to Washington?  Why aren't more people leaving California (like they are New York, New Jersey, Connecticut, and Illinois)?
