Visualizing the Language of Eugenics
The first set are about place - one considers country of origin other than the United States and the other captures data about state of birth for those who were born in the U.S.

Finally, and in many ways the most disturbing, are the evidence used to support a sterilization recommendation. First are the diagnoses of patients who were recommended for sterilization. Of particular note are the "not-feebleminded" and "normal," but it's worth noting that the protocols for diagnosis of clinical conditions were very different in the early 20th century and would rarely hold up in modern clinical assessments in the same way.
In addition to using clinical diagnoses to support sterilization recommendations, many facilities used criminal activity as evidence of mental incapacity, in this visualization we see the kinds of reported criminal activity captured with the records.
