Genealogists! You Must See This
And non-genealogists will be amazed by it, too.
Today's NY Times has an interactive map that shows -- by COUNTY! -- where the immigrants came from in each decade, going back to 1880.
Take a look!
Update: An instructive thing to do is select a particular country from the drop-down menu in the upper left, then slide the date bar from 1880 to 2000 watching how the immigration pattern changes through the decades.
If you select Mexico, you will see the number of Mexican-born people gradually increase in the Southwest then, suddenly, they all but disappear in 1930. What happened? Did the Great Depression send them back to Mexico? Of course, in more recent years the Mexican immigration pattern explodes.
