No matter which side of the immigration fence you happen to be sitting on, there's not much doubt about how the patterns have shifted over the past 40 years. As another part of that Brookings study (see earlier post), the share of immigrants coming in from Mexico, the Caribbean and Latin America has grown from 19 percent in 1960 to 53 percent in 2008. Europe's share of total immigrants has fallen from 60 percent to 13 percent.
