Sioux Nation Reservation Is Least Healthy Place in U.S.

Sioux County, North Dakota, is the least healthy place in the U.S. for the second consecutive year, while Los Alamos County, New Mexico, is the healthiest, according to a study.

Sioux County, headquarters of the Standing Rock Sioux Nation, which covers about 1 million acres in North and South Dakota, has the highest rate of premature deaths in the nation, researchers at the University of Wisconsin found. The county loses almost 24 years of potential life per 100 residents, compared to less than 3 years lost per 100 in Los Alamos, home to the Los Alamos National Laboratory.
