Bloomberg News has a great interactive map based on the 2010 census that lets you see where 20 different groups of immigrants are in the US. While I could not find my father's (the CzechRepublic), it did include all of the bigger immigrant groups. For examples, above is a picture of where the Dutch descendants are located. I found the link at Chart Porn. Now for those of you who use Google Docs (see below) and another delivery device for your students (we are mandated to use Blackboard), you can just go to an assignment where you have information on immigration, add the map above and not have to re-upload it into Blackboard.
