An interactive map showing where Americans are moving from and to:

More than 10 million Americans moved from one county to another during 2008.

Most of the highlighted cities have similar migratory patterns. Folks moving in, moving out; it basically balances out. There are only two exceptions I noticed.

The first, was Manhattan, where far more people were moving into than out of. How that island hasn’t sunk from its own weight baffles me.

And then there’s Detroit.
