Jason sent me the great interactive graphic below from the folks at the New York Times (April 7, 2009). It shows the amount and countries of origin of foreign-born workers in the United States. Note that the top five sources of immigrant employment in the U.S., in descending order, are Mexico, Philippines, India, China, and El Salvador. We have over 5 million workers from Mexico, but the second-place country--the Philippines--was the source of only about 850,000. U.S. Immigration is truly only about Mexico.
The data come from the most recent survey of the Census Bureau's American Community Survey via the Minnesota Population Center. For a link to other great graphics see, "Perfecting the visual presentation of information."
