The category for listing disabilities is defined as "Deaf & Dumb, Blind, Insane, or Idiotic.” Slaveholders include disabilities as a census category in order to track the "soundness" of enslaved Black people's physical and intellectual capacities. Slaveholders diagnose Black abolitionists as being of "unsound mind," listing this as the reason for uprisings and abolitionists' lack of ability to "see the benefit" of contributing to a slave labor economy.
