Between 1995 and 2010, millions of Americans moved between the states, taking with them over $2 trillion in adjusted gross incomes. Two trillion dollars is equivalent to the GDP of California, the ninth largest in the world. It’s a lot of money. Some states, like Florida, saw tremendous gains ($86.4 billion), while others, like New York, experienced massive losses ($58.6 billion). People moved, and they took their working wealth with them.
