Latinos in the USA
Looking at the mix of European, African and Native American ancestry, self-identified Latinos in the 23andMe database had the most diversity in their ancestry. But again, just as the mix of ancestry among African Americans and whites differed from state-to state, so too did Latinos, which again sheds more light on their social history.
On average Latinos had about 70 percent European ancestry, 14 percent Native American ancestry and 6 percent African ancestry. The remainder ancestry is difficult to assign because the DNA is either shared by a number of different populations around the world, or because it’s from understudied populations, such as Native Americans. Obviously that large “unassigned” percentage means that those “averages” could be higher. As with African Americans, looking at the regional and state-to-state numbers for self-identified Latinos, the differences are striking.
Recent studies have shown that countries across South America, the Caribbean, and Mexico have different profiles of genetic ancestry molded by each populations’ unique history. According to 23andMe’s data, the United States has its own set of unique regional histories.
For example, some Latinos have no discernible Native American ancestry, while in others have as much as 50 percent of the ancestry being Native American. Latinos in states in the Southwest, bordering Mexico — New Mexico, Texas, California and Arizona — have the greatest percentage of Native American ancestry. Latinos in states with the largest proportion of African Americans in their population — South Carolina, Louisiana and Alabama — have the highest percentage of African Ancestry.
