Wonder Where Most New U.S. Permanent Residents Come From? See DHS’s Map

The Department of Homeland Security (DHS) has released a series of maps showing the countries of origin of U.S. lawful permanent residents, spanning the years from 1820 to 2010. Scanning the graphics is like a timeline of major or cataclysmic world events — there’s a spike in Irish immigration soon after the time of the potato famine (1845); a spike in Cuban immigration shortly after Castro came to power in the 1950s — and a current spike in immigration from India (Silicon Valley is calling, I believe).

But doesn’t anyone want to leave Iceland?
