This is cool, and maybe even useful. I caught Map: Where Americans Are Moving yesterday on

The map is interactive, so you can click on any county and see movement in and out during 2008. The view I chose above shows how people move into Santa Clara County, CA (Silicon Valley) from the north central areas, and from there they tend to move out to the West Coast and Texas. What does this tell us about entrepreneurship and the Silicon Valley.

Then I did it from my home county Lane County OR, which is where we moved to from Silicon Valley 18 years ago. The patterns are radically different. People move here mainly from the west, and especially California; and it seems they leave for the west too, mainly Washington. Does this look like a gradual shift northward?
