Today’s map comes a day late – we’ve been hard at work getting the data ready. We’ve updated our interactive State Migration Calculator with the latest IRS data, and it now includes migration in 2008-09. I’ve used the new data to create a map of interstate movement of income over the past decade. Florida is the big winner – migrants bought a net $70 billion dollars in annual income into the state between 1999 and 2009. New York, on the other hand, lost the most income: $45 billion.
