In the United States today, interstate migration is becoming a more and more prominent topic. A new book called How Money Walks has used IRS data to put hard numbers to which states are losing and which states are gaining wealth due to interstate migration.
Most of it won't surprise you: the northeast and the rust belt states, along with California, are losing residents at incredibly high rates. Most of the south and southwest is gaining. Texas, Florida, Arizona, and Colorado lead the way in total wealth gained due to migration. Some are surprising, though: Washington State, for example, has been a fairly large gainer. And the outlier in the South is Louisiana.
