Definition
This variable identifies if the person was considered "insane," as contemporaries understood that term. The enumeration instructions in 1850 did not include a definition of "insane" . However, the 1860 instructions to enumerators stated that a person institutionalized for insanity should be so labeled, but someone "competent to manage his or her business affairs without manifesting any symptoms of insanity to an ordinary observer" should not be. "As a general rule," these instructions continued, "the term Insanity applies to individuals who once possessed mental faculties which have become impaired," not to persons suffering a mental disability from birth.
