I need a list of unconventional, interesting facts related to modern
international migration of human beings. I think I heard once that
Ecuador's biggest import is foreign money from emigrants sending money
back to their families. Anything that is remarkable, outrageous, or
startling is helpful-- and sources are, of course, important to note.
I know this is vague, but I just need some interesting facts related
to migration, immigration, emigration, historical patterns-- anything.
Thanks.
