The Jukes family was a New York hill family stuied in the late 19th and early 20th centuries. The studies are part of a series of other family studies, including the Kallikaks, the Zeros and the Nams, that were often quoted as arguments in support of eugenics, though the original Jukes study, by Richard L. Dugdale, placed considerable emphasis on the environment as a determining factor in criminality, disease and poverty.
