The U.S. Census Bureau has just released a set of county-to-county migration flow tables based on American Community Survey data. What does that mean in plain language? On a county-by-county basis you can now track where movers to your county moved from and where those who left went.
And, instead of having to wade through a bunch of intimidating databases, the Census Bureau has created a nifty visualization to allow you to see and extract information on migration. You can access this visualization by clicking here.
