One analyst says it's a sign people in California are fed up with high housing prices and urban sprawl. The Census Bureau says more people left the state during the last half of the 1990's than moved in from other states. That's the first time that's ever happened! California gained more than a million people in the period, but lost more than two million. California was once part of Mexico , and the saying goes: it soon will be again, at least culturally, because most of its population increase came from south of the border.
( New York , Pennsylvania , and some other northeastern states in the "Rust Belt" also had more out-migration than in-migration.) States in the "Sun Belt," (the South and a couple of desert states) on the other hand, continue to have more people moving in than out. Retirement destination-Florida leads the pack, but Georgia , North Carolina , Arizona , and Nevada are also in the top five.
