The Most Unusual Ancestry in Each State

36. Oklahoma
> Location quotient of ancestry:
7.3
> Most unique ancestry: American Indian
> Percentage of state residents identifying as American Indian: 14.1%
> Share of U.S. American Indian population living in state: 8.4%

Oklahoma has the largest share of American Indian residents in the country. More than 14% of Oklahoma residents identify as American Indian, or 8.4% of the total U.S. American Indian population. Unlike many of the most unique heritages in a state, the American Indian population is indigenous to Oklahoma. American Indian populations were forcibly relocated by European settlers as early as the 15th century, and their location today is largely dictated by state and federal policies. Unlike those in other parts of the country, most Oklahoman tribes were able to stay within the state, and others from east of the Mississippi were relocated there as well.

Like many of those with African ancestry, the first Congolese came to the United States as slaves in the 17th century.

> Location quotient of ancestry:
11.5

Of the 231,474 U.S. citizens who identify as Pennsylvania German, nearly half of them live in Pennsylvania. At one point, all Pennsylvania Germans lived in Pennsylvania, as the ancestral designation is the product of immigrants from southwest Germany who settled in the state in the late 17th and 18th centuries. Pennsylvania Germans have since migrated to other states, and they are highly concentrated in Delaware, Ohio, and Indiana today. Pennsylvania Germans speak a dialect of the German language, which is popular amongst Amish communities.

39. Rhode Island

Just 2.1% of Rhode Island residents identify as Cape Verdean, but nearly 21% of all individuals reporting such heritage nationwide live in the state. One of the only museums dedicated to Cape Verdean culture is in East Providence. According to the museum’s exhibit, most Cape Verdean-Americans owe their ancestry to whalers and seasonal cranberry farm workers migrating to New England.
