About 13% of the world's adults -- or about 630 million people -- say they would like to leave their country and move somewhere else permanently. For roughly 138 million people, that somewhere else would be the U.S. -- the No. 1 desired destination for potential migrants. The U.K., Canada, and France also rank among the top choices for potential migrants.
