Immigration map

From the NYT:

Immigration Explorer

If you want to really freak out your anti-immigration neighbor, show them what happens when you select "Mexico" and drag the slider from 1970 to 2000. But of course this is another way in which maps can mislead. The population circles are scaled so as to be proportional to the number of people they represent, but on the map those circles cover a certain geographic area, which is not what they're supposed to represent. You could easily think there are no non-Mexicans left in southern California, but I'm pretty sure that's not the case.
