The map that shows where America came from:

Fascinating illustration shows the ancestry of EVERY county in the US      

Census data shows heritage of 317 million modern Americans     
Clusters show where immigrants from different nations chose to settle     
Largest ancestry grouping in the nation are of German descent with almost 50 million people     African American or Black is the second largest grouping with just over 40 million people     
Almost 20 million people claim to have 'American' ancestry for political reasons and because they are unsure of their family's genealogy
