What about Afro-Americans? I think they are more than mentioned here "OTHER" - Kemalettin Bulamacı

Actually, most African-Americans that are descended from slaves would have surnames that derived from their ancestors' European-American owners' surnames. And some of those names are on this map (Jackson, Robinson). As far as recent immigrants from Africa, their names wouldn't show up on this list due to them not being among the most common names in the US. My surname is one of the most common surnames in Ireland and it doesn't show up on this list even in the Boston area. So it's not meant to be some accurate representation of the ethnic diversity of the US. It's just a fun infographic. - Spidra Webster

From the blog post that goes with this graphic (http://blogs.ngm.com/blog_ce...): "Slaves often took their owners' names, so about one in five Americans now named Smith are African American. In addition, many newcomers' names were anglicized to ease assimilation. The map's scale matters too. 'If we did a map of New York like this,' says project member James Cheshire, 'the diversity would be phenomenal' -- a testament to that city's role as a once-and-present gateway to America." - Tom Stocky

It's amazing how few "others" there are: Patel (Indian), Cohen (Hebrew?), Kim (Korean), and Nguyen (Vietnamese). Are really only 4 top-25 surnames in the US that didn't originate in those 10 locations? - Gabe

In sufficient concentrations, probably. - Andrew C (see frenf.it)
