I found this rather startling:

In 2008, over two million US citizens fled the United States for greener pastures, and while this figure still represents less than 1% of the total US population, the trend is astounding. Between 2006-2008, the average number of US permanent resident filings stood at roughly 1.1 million/year, placing the legal inflow at negative 900,000 people. In a country of immigrants, the trend is emigration, not immigration.

If thatโ€™s correct, I canโ€™t think events in 2009 will do anything to diminish the flow. What I wonder is: Where did those 2 million go? Britons, Canadians, Europeans, etc, who seek โ€œgreener pasturesโ€ generally wind up in the U.S. For most of us immigrants, this is the last stop on the tour: Thereโ€™s nowhere else to go. So where on the planet do a couple of million Americans go to find somewhere โ€greenerโ€?
