I just found this really cool map on immigration. The map is a visual of immigration from 1850-2010. What makes the map so awesome is you can see where people were migrating to during any time. What I really find interesting is how immigration is changing. For example, not many Irish are migrating as they once were. Click here for the map.
See the interactive graphic here University of Richmond/Digital Scholarship Lab. Almost all of us living in the United States today are immigrants. Where was your family originally from?
