Here’s a nice little mashup from Forbes. They created an interactive map visualizing migration data into and out of US counties based on 2008 IRS data*. The black lines represent people moving to a certain place, the red lines are people moving out. TONS of people moving to SF (where I live). No wonder I have to stand in line so long for my strawberry balsamic ice cream fix from BiRite Creamery!
*I went looking for said IRS migration data and found that:
The County-to-County Migration Data are updated annually and available for purchase as follows:
* $200 per year for the entire United States
* $10 per year per State
* $500 for the entire United States for all years
It’s unfortunate to say the least that IRS feels the need to charge for access to public domain data that the public has already paid for once already. Has anyone come across other data sets like this? please leave us a comment.
