The Tax Foundation has created a “migration calculator” based on data from the Internal Revenue Service, tabulating the number of individuals moving between states each year, and income affected by the shifts.

The calculator shows that 612,520 people renounced their citizenship in New York State and moved to Florida in the 10-year period, taking with them $19.7 billion in adjusted growth income.

Between 2009 and 2010 alone, 40,195 New York residents moved to Florida, taking $1.3 billion in income.
